Accelerating the formation and development of new quality productive forces is an inevitable requirement for social and economic development. This paper constructs a comprehensive index system of the new quality productive forces (NQPF) from two dimensions: the realistic basis and the realistic performance of the NQPF. It determines the weights of the indexes using the projection tracing model optimized by genetic algorithm,measures the NQPF level in 30 provincial-level regions of China from 2013 to 2022,and analyzes the spatial pattern and evolution characteristics of provincial-level NQPF in China over the past decade using the methods of Dagum-Gini coefficient,Kernel's density estimation,Moran's I,gravitational model and so on. The results show that: 1) The level of China's provincial-level NQPF shows the characteristic of gradient development which is higher in the east of China and lower in the west of China. 2) The level of NQPF is increasing across regions,while the differences are gradually decreasing. The spatial pattern between provincial-level regions shows the characteristics of "low-high" and "high-low" agglomeration. 3) The intensity of gravitational correlation between provincial-level regions is becoming more complicated and dense,and is roughly proportional to the level of NQPF. The research holds great practical significance for improving the NQPF level and promoting high-quality economic development.

Developing new quality productive forces (NQPF) tailored to local conditions is a fundamental requirement for advancing high-quality development. Since the 18th National Congress of the Communist Party of China,China has gradually formed a NQPF strategic framework integrating policy support,factor allocation,and industry guidance. This paper systematically examines the evolution and spatial organization of NQPF,identifies their spatial distribution from the perspective of source-sink functions,and explores strategic positioning and policy guidance for different functional types,including development centers,sources,reservoirs,and hinterlands. Research findings are as following: 1) The development of NQPF exhibits the spatial convergence of industry and innovation,spatial dependence on locational advantages,and diversification of factor flow patterns. These effects contribute to the regional source-sink functions of factor coupling,efficacy differentiation,and scale nesting. 2) During the study period,the sink and source functions of NQPF in China exhibited an uneven distributionpattern that is higher in the north of China than that in the south of China,and higher in the south of China than that in the north of China,respectively. It forms eastern,southern,northern,and western functional zones. Therefore,it is essential to implement policies that align with the development orientation and resource endowment of different regions,foster a combination of source-sink functions,leverage complementary advantages,and coordinate cross-regional layouts to achieve high-quality regional coordination and development.

Promoting coordinated regional development is an important approach to basically achieving modernization with Chinese characteristics. On the basis of summarizing the new trends and referential experiences of regional coordinated development during the "14th Five-Year Plan" period in China, this article puts forward four laws of economic geography that are applicable to the current stage of regional coordinated development in our country. Specifically: 1) National modernization and coordinated regional development are symbiotic, there exists no national modernization with pronounced disparities in inter-regional economic development levels. 2) The structural characteristics of regional geographical functions and the redistribution process of economic gains among regions determine the equilibrium state of living standards and economic development levels between urban and rural areas and among regions. 3) The different from the period of building a moderately prosperous society is that human resources and technological progress have become dominant and decisive factors in the economic development processes of both developed and underdeveloped regions during the modernization period. 4) Regionally differentiated development relying on comparative advantages serves as the cornerstone for enhancing the overall efficacy of national modernization, and increasing the value of ecological products is the key focus of institutional reform for promoting coordinated regional development. Finally, this article also conducts an initial discussion on the adaptive strategies for promoting coordinated regional development during the "15th Five-Year Plan" period.

This paper constructs a multidimensional evaluation index of geo-economic linkage intensity,uses the methods of polygon method,vector sum method,and grey relational analysis to comparatively analyze the evolution of geo-economic linkage intensity between China,Russia and Central Asian countries,and its the influencing factors. The results show that: 1) The geo-economic linkage intensity between China and Central Asian countries overall shows a trend of fluctuating growth,while the geo-economic linkage intensity between Russia and Central Asian countries is basically stable. The geo-economic linkage intensity between Russia and Central Asian countries is higher than that of China-Russia. 2) The role of geopolitics in the geo-economic linkages between China,Russia and Central Asian countries has declined,while the role of trade and transportation in the geo-economic linkages between China,Russia and Central Asian countries has risen. The geo-economic linkages between China and Central Asian countries have gradually shifted from being jointly dominated by trade,transportation,and geopolitics to being jointly dominated by trade and investment,while the geo-economic linkages between Russia and Central Asian countries have shifted from being jointly dominated by tourism,trade,and geopolitics to being jointly dominated by trade,tourism,and transportation. 3) The geo-economic linkage intensities of China-Central Asian countries and Russia-Central Asian countries both show the pattern which is higher in north of Central Asia and lower in the south of Central Asia,but the geo-economic linkage intensities between Russia and the four countries in the south of Kazakhstan fluctuate greatly. 4) Resource endowment is a common and important driving force for the evolution of the geo-economic linkage intensity between China,Russia and Central Asian countries. The geo-economic linkages between China and Central Asian countries are more dependent on market size compared with Russia,and the geo-economic linkages between Russia and Central Asian countries are more sensitive to the level of economic development and political stability than that of China.

The urban-rural integrated development model represents a comprehensive paradigm. It is shaped by market forces and policy instruments, designed to facilitate bidirectional flows of production factors, ensuring equal exchange, fair resource sharing, and fostering mutual prosperity between urban and rural regions. The pursuit of innovative models of urban-rural integrated development is pivotal to achieve urban-rural integration in China. Based on a systematical review of global urban-rural integrated development practice models and extensive fieldworks, this study focuses on typical cases from national urban-rural integration pilot areas and proposes six typical practical models: the Extended-Chain and Strengthened-Chain Model for urban-rural industrial integration, the Equal Legal Price and Equal Market Rights Model for urban-rural construction land integration,the Unified Construction and Distribution for urban-rural infrastructure integration, the Same Standards, Equal Benefit Model for urban-rural public services integration, the Village Super League Model for integrating urban-rural cultural, tourism and sports,and the Delimitation of Property Rights Model for rural homestead land reform. These models offer successful paradigms applicable to nationwide urban-rural integration practices. However, there is no one-size-fits-all model for urban-rural integrated development, as these models display regional and developmental stage heterogeneity. These experience should be learned from but not rigidly replicated.

This study employs various complex network methods to characterize the evolution of the global lithium resource trade network on a long-time scale, analyze the network's topological structure,and reveal its resilience. The findings include as follows: 1) The overall scale of global lithium resource trade shows a steady development followed by rapid growth, with lithium carbonate trade obviously surpassing lithium hydroxide. 2) The scale and density of global lithium resource trade network continue to increase,gradually form a trade pattern dominated by a few core countries,characterized by clear hierarchical features and spatial imbalance. 3) Chile and Argentina are exporters of lithium resources with global influence. China, Japan, South Korea, the United States, Germany, the Netherlands, Belgium, Russia, and Canada have long-term core positions. 4) The backbone structure of the global lithium resource trade network is continually enriched and expanded,demonstrating a development trend with a few countries as core nodes connecting regional trade groups. 5) The resilience of the global lithium resource trade network is declining, with a few countries and trade relations playing a decisive role in the network's structural connectivity. There is a crisis of potential collapse in the lithium resource trade network after facing shocks. Based on the above, this paper proposes policy recommendations to promote China's lithium resource trade cooperation and ensure the security of lithium resource supply.

The uneven spatial distribution and agglomeration of economic geographic space is the normal state,the agglomeration advantages of the core areas makes the innovation research in core areas become the mainstream,innovation in peripheral regions is often neglected and underestimated. However,in recent years, there has been a rise in innovative activity in peripheral regions, which has attracted the attention and explanation of academic circles. The current research investigates innovation in peripheral regions from multidisciplinary perspectives. However, there is still no consensus on the conceptual definition,innovation trajectories,and other related aspects. Additionally,there is no systematic literature review or mechanism explanation. Therefore,this paper conducts a comprehensive examination of innovation in peripheral regions,elucidating the meaning of "periphery", defining the behavior of "innovation in peripheral regions", and creatively constructs an analytical framework to comprehend the trajectories of innovation in peripheral regions via "internal,external,and systemic innovation". Innovation in peripheral regions necessitates the synchronized alignment of regional initiative,the external environment,and regional capability. In addition to exploring its own capabilities and taking proactive measures to achieve "internal innovation",it also needs to incorporate new external knowledge to achieve "external innovation" and embed itself into the system to reach multi-scale "systemic innovation".

This article constructs a comprehensive evaluation index system of the development level of new quality productive forces. Based on the super-efficiency SBM-DEA model,the entropy weight-TOPSIS method,exploratory spatial data analysis methods,and spatiotemporal geographical weighted regression models,it analyzes the evolution characteristics and influencing factors of China's new quality productive forces from 2013 to 2022,and explores the spatiotemporal differences in the impact of different influencing factors. It's found that: 1) The development level of new quality productive forces shows an upward trend,with a spatial distribution pattern of "high in the east of China and low in the west of China", and significant spatial differences in the level of new quality productive forces. 2) The development of new quality productive forces exhibits significant positive spatial autocorrelation and spatial clustering,with high-high clustering areas mainly located in the eastern coastal regions and low-low clustering areas mainly in the western regions. The absolute spatial differences in new quality productive forces have expanded in recent years. 3) Economic, educational, policy, and resource factors influence new qualitative productivity. Domestic economic development levels, foreign trade levels, overall educational investment levels, higher education development levels, and the overall policy focus have a positive impact on new qualitative productivity, while the availability of water resources and mineral resources has an overall negative impact. Additionally, the influence of various factors varies across time and space.

This study analyzes the coupling coordination mechanism between green development and common prosperity in the Yellow River basin,and uses the coupling coordination degree model to measure the coupling coordination relationship between green development efficiency and common prosperity development in the Yellow River basin from 2011 to 2020. It analyzes the spatial-temporal evolution characteristics and influencing factors of the coupling coordination degree between green development and common prosperity using the exploratory spatial data analysis and the geographical detector. The research shows that: 1) The green development efficiency in the Yellow River basin exhibited slow growth and fluctuation from 2011 to 2020,with a spatial gradient pattern of "downstream > midstream > upstream". The common prosperity index showed a steady upward trajectory of evolution,and its spatial distribution evolved from a low-level equilibrium pattern to a high-level imbalance pattern. 2) The coupling coordination degree between green development and common prosperity in the Yellow River basin demonstrated an upward fluctuation trend,forming a "center-periphery" circle structure with provincial capital city as the high-level coordination center in space. The coupling coordination degree between green development and common prosperity has positive spatial autocorrelation,and has the spatial club convergence effect characterized by high-high agglomeration and low-low agglomeration,but it tended towards weakening spatial autocorrelation. 3) Financial development,sci-tech- innovation,digital economy and urbanization level are the leading factors driving the spatial differentiation of the coupling coordination between green development and common prosperity in the Yellow River basin. There is a significant spatial heterogeneity in the effect strength of the influencing factors on the coupling coordination degree,and the explanatory power of each factor interaction has the characteristics of double factor enhancement and nonlinear enhancement.

The concept of human capital provides an important research perspective for understanding the relationship between industry and people. The spatial coordinated evolution between human capital and industrial structure is of great significance in optimizing resource allocation and stimulating regional development potential. The Beijing-Tianjin-Hebei region is in the crucial period of industrial structure upgrading and innovation-driven development. This study demonstrates the spatial pattern evolution of the human capital level and industrial structure upgrading level at the county level, and explores their spatial coupling and synergy. The results show that: 1) The levels of human capital and industrial structure upgrading in the Beijing-Tianjin-Hebei region have been increasing rapidly in 2000-2020, resulting in the average degree of coupling coordination between them in this region transmitted from low-level coordinating stage to medium-level coordinating stage. 17% of counties reached the high-level coordinating stage, mainly distributed in municipal districts around large cities such as Beijing and Tianjin. 2) The spatial pattern of the degree of coupling coordination presents the core-periphery structure, which means that human capital and industrial structure upgrading have a spatially interacted impact. This relationship can be hampered by the administrative boundary and has been enhanced in the north of Beijing-Tianjin-Hebei region while reduced in the south of Beijing-Tianjin-Hebei region. 3) Although the level of educational human capital has been increasing rapidly, the spatial polarization is still within the region, indicating the spatial mismatch between education and industry is the main challenge to achieving regional synergistic development. The results provide suggestions and references for allocating regional human capital rationally and promoting the high-quality development of the Beijing-Tianjin-Hebei region.

Rapid urbanization has resulted in the reorganization of rural social space and the change of residential morphologies, as well as practical problems such as rural social differentiation and spatial imbalance. Understanding the logical mechanism driving changes in rural residential morphologies has become a crucial pathway for promoting new-type urbanization and rural vitalization. This paper explores the conceptual framework of the changes of rural residential morphologies, describes the process, characteristics and mechanism of the changes of rural residential morphologies, as well as its coupling relationship and mutual feeding mechanism with rural spatial transformation. It further discusses strateges for managing these changes in rural residential morphologies along with related plans for spatial governance transformation. The conclusions are drawn as follows: 1) The new-type urbanization putting people first leads to the changes of rural population flow and migration mode, and further leads to the rapid reorganization of rural social space and the drastic changes in residential forms. 2) The new-type urbanization process drives the changes of rural residential morphologies through four evolution stages: the change of housing pattern, the inefficient use of housing, the deviation of housing function and the idle of housing. Economic element, socio-cultural element and urban-rural policies have direct driving role, indirect influence role and macro-guiding role respectively. 3) The changes of rural residential morphologies promote the transformation of rural living, production, ecological and cultural spaces, and the coupled and interconnected mutual feed mechanism makes all kinds of spaces also exert influences on rural residential morphologies. 4) Under the guidance of smart development, the scientific preparation of village spatial planning is needed, as well as the use of digital technology to achieve rural cross-border governance. Promoting the diversified governance by boosting the urban-rural integrated development and improving the mechanism of rural spatial governance are the trends of spatial governance transformation for the in-depth implementation of the strategies of new-type urbanization and rural vitalization.

Based on the essential requirements of Chinese path to modernization, this paper explores the basic logic and innovative path of territorial spatial planning, and provides references for building an inclusive, sustainable, and resilient territorial spatial planning system. It uses the theoretical analysis and inductive-deductive method to discuss the basic relationship and innovation path of the territorial spatial planning system in the future. The research results are as follows: 1) The territorial spatial planning in the process of Chinese path to modernization needs to coordinate five basic relationships: the relationship between human civilization form and planning value orientation, the relationship between energy and resource security and planning goal setting, the relationship between sci-technological revolution and planning connotation iteration, the relationship between climate change and planning function synergy, and the relationship between political and economic pattern and planning paradigm change. 2) The innovation path of a future-oriented territorial spatial planning system needs to coordinate five innovative paths, including "modernity" and "localization" of value radius, "common divisor" and "common multiple" of the target system, "synchronic" and "diachrony" of the connotation logic, "topology" and "relativity" of the functional attributes, "typification" and "normalization" of paradigm features. 3) There is an urgent need to grasp three new directions in the development of the territorial spatial planning system to meet future trends. The first is the theoretical construction of the future territorial spatial planning system in the context of Chinese path to modernization. The second is the practical exploration of the future territorial spatial planning system for the modernization of the national governance system and governance capacity. The third is the scientific limits of the future territorial spatial planning system, the relationship between subject and object, the expansion of spatial principles in different application scenarios, technical innovation, and conceptual transformation.

Based on the two connotations of development and sharing of common prosperity,and combining with the development characteristics of counties,this paper constructs the evaluation system of county-level common prosperity from four dimension which are economic strength,development forces,income distribution and inclusive service. It uses the projection pursuit method to measure the common prosperity level of 1663 Chinese counties from 2008 to 2021. With the help of the policy of demonstration county for e-commerce in rural areas as a quasi-natural experiment,it empirically tests the impact of e-commerce development on county common prosperity and its mechanism using a multi-period and spatial DID model. Results show that: 1) The level of common prosperity in Chinese counties as a whole has increased significantly,but the gap between regions has widened,showing the development trend of "highest in the east of China,fastest in the center of China,stable in the west of China,and slowest in the northeast of China". 2) The e-commerce policy in rural demonstration counties has significantly improved the level of county common prosperity,and there is a positive spatial spillover effect,with the policy effect increasing over time. 3) Heterogeneity analysis finds that the positive effect of e-commerce on county common prosperity is more significant in regions with higher level of human capital as well as stronger county governance capacity. 4) Mechanism analysis shows that e-commerce development enhances the level of county common prosperity by releasing market potential and optimizing the employment structure.

This article re-adjusts the calculation formula for the labor income share, estimates the labor income share of China's provincial-level regions from 1978 to 2017, calculates the bias parameters of technological progress in each provincial-level regions using a standardized supply-side system approach,and conducts a trend analysis of the labor income share across provincial-level regions. It uses the Dagum Gini coefficient to depict the evolution pattern of inter-provincial differences in China's labor income share,and analyzes its sources. Based on the spatial econometric method,it explores the reasons behind the formation of the spatial distribution pattern of factor income. It's found that: 1) The overall spatial distribution pattern of labor income share exhibits a trend,which is the highest in the west of China,followed by central China and the east of China, the more developed region is, the lower the labor income share is. The spatial distribution patterns of depreciation and net production taxes in GDP are opposite to this trend,while the spatial distribution pattern of mixed income in GDP aligns with it. 2) The overall average trend of labor income share of all provincial-level regions showed an inverted U-shape,with the most obvious upward trend in Beijing and Shanghai and the most obvious downward trend in Xizang. Technological progress is biased toward capital in most provincial-level regions,which is a crucial factor contributing to the notable decline in the labor income share. 3) The Gini coefficient reflecting inter-provincial differences in labor income share remains relatively large. From the perspective of intra-regional disparities, the eastern region exhibits the largest internal gap, which is also showing a significant downward trend. In terms of inter-regional Gini coefficients,the disparities between the eastern and central regions, as well as between the eastern and western regions, are more pronounced,while the disparity between the central and western regions is relatively smaller. 4) Spatial econometric analysis reveals that industrial structure exerts a negative spatial spillover effect on labor income share.

The widening gap between the north and the south in China has become a typical phenomenon of unbalanced and inadequate regional development. This paper uses the nighttime satellite light data from 1992 to 2020 to analyze the North-South gap and its dynamic evolution characteristics, evaluates its global and local convergence, and explores the main factors affecting the convergence of the North-South gap. The empirical results show that: 1) During the sample period, the North-South gap showed a downward-upward trend of repeated fluctuations, but after 2013, it showed a new round of accelerated expansion trend. 2) The South and the North in China both experienced a process from non-existent club convergence to club convergence, which is mainly reflected divergence in the southern region and convergence in the northern region. 3) There are obvious local convergence characteristics in the southern and northern regions, but the steady-state level of convergence in different regions is differentiated. 4) The gap between the business environment and the innovation level is the main factor causing the accelerated differentiation between the northern and the southern regions. Technological progress and innovation level are the leading forces leading to the internal differentiation in the southern region, and the change of industrial structure has a positive effect on narrowing the internal gap in the northern region. This paper provides an effective policy reference for narrowing the gap between the northern and the southern regions and promoting regional coordinated development.

As China's economy transitions from rapid growth to high-quality development,innovation has been the core driving force behind economic advancement. The Third Plenary Session of the 20th Central Committee of the Communist Party of China explicitly emphasized the need to "promote the Beijing-Tianjin-Hebei region,the Yangtze River Delta,and the Guangdong-Hong Kong-Macao Greater Bay Area and other regions to better play the role of engine of high-quality development". Based on reviewing studies on innovation-driven high-quality development and the role of urban agglomerations as engines of such growth,this article built a theoretical innovation-driven mechanism model of three major coastal urban agglomerations being engines of Chinese high-quality development. It analyzed the innovative development basis and existing problems of three major coastal urban agglomerations to become engines of high-quality development. Based on this analysis,it puts forward some strategies and policy recommendations to enhance the role of three major coastal agglomerations as innovation-driven engines. It is expected to provide research support and experience reference for the realization of innovation as the driving force,three major coastal urban agglomerations as engines,and promote the Chinese high-quality development.

This study quantitatively evaluates the coordination level between pollution reduction and carbon reduction in 30 provincial-level regions in China from 2006 to 2020. It analyzes the spatiotemporal evolution trend of this coordination level using the Dagum Gini coefficient and spatial Markov chain. Additionally, it empirically tests the impact of green technology innovation on the coordination level between pollution reduction and carbon reduction. The research findings are as follows: 1) The overall trend of the coordination level between pollution reduction and carbon reduction in China is increasing, exhibiting a "club convergence" phenomenon. The spatial difference of the coordination level between pollution reduction and carbon reduction shows a downward trend in China and three major regions. 2) Green technology innovation plays a significant role in enhancing the coordination level between pollution reduction and carbon reduction, while environmental regulation and government financial support significantly enhance its promoting role. 3) Energy consumption intensity reveals the mechanism of green technology innovation affecting the coordination level between pollution reduction and carbon reduction, environmental regulation and government financial support play negative and positive regulatory roles on this impact mechanism, respectively. 4) Heterogeneity analysis reveals that green technology innovation has a significant promoting role in the coordination level between pollution-carbon reduction for central and western regions, but not for eastern region.

The Third Plenary Session of the 20th CPC Central Committee explicitly outlined the need to "improve the institutional system of major functional zones". This paper evaluates the policy value and implementation effectiveness of major functional zones by examining three scientific connotations: emphasizing the fundamental role of resource and environmental carrying capacity,highlighting regional comparative advantages,and adhering to a goal-oriented approach for sustainable development. It uncovers significant developmental disparities among different major functional zones. Based on basic theories and methods in economic geography, this paper discusses reform directions for improving the institutional system of major functional zones,including: building an institutional framework for the major functional zones that is compatible with high-quality development and China's modernization construction,enhancing a coordinated development system between major function and superimposed function,and creating an institutional framework based on major functional zones to expedite the formation of a new territorial system and integrated functional zone layout. Furthermore,it delves into in-depth discussions on key reforms and innovations for achieving high-quality development in major functional zones as well as improving the institutional system. This paper contends that economic geography has played a crucial supporting role in shaping and developing major functional zones. Thus,enhancing the institutional system will serve as a new driving force for economic geography's advancement in the new era.

The high-quality development is a key driver for the evolution of China's economy and society to a higher form. This paper constructs an evaluation index system for the high-quality development of the Central Plains Urban Agglomeration from five dimensions: innovation, coordination, green, openness, and sharing. It employs methods such as the CRITIC method, Kernel density estimation, Markov chain, and Geodetector to explore the spatial-temporal pattern and influencing factors of high-quality development across 29 prefecture-level cities in the Central Plains Urban Agglomeration from 2011 to 2021.The study finds that: 1) From 2011 to 2021, the Central Plains Urban Agglomeration has shown a significant upward trend in the level of high-quality development. Innovation and sharing dimensions show the characteristics of rapid development, while coordination, openness, and green dimensions show the characteristics of more slow development but have still increased positively. 2) The high-quality development of the Central Plains Urban Agglomeration demonstrates a positive trend, with most cities maintaining their current levels or shifting towards higher levels, and cities at higher levels exhibit significant stability and a "club convergence" phenomenon. 3) The five dimensions of high-quality development exhibit significant spatial development imbalances: high-value areas in the innovation dimension are dispersed in a point-like distribution, while high-value areas in the coordination, innovation, and sharing dimensions are concentrated in specific areas, with the core development areas and northern cross-regional collaborative development demonstration areas showing significantly higher levels than other areas. Meanwhile, the green dimension is gradually moving towards balance. 4) In terms of the social, economic, and policy factors affecting the high-quality development level of the Central Plains Urban Agglomeration, the main driving forces are ranked as follows from high to low: digital economy, financial conditions, capital investment, education level, human capital. These factors show significant differences in their driving effects across different dimensions. This study provides new theoretical and empirical support for the high-quality development of the Central Plains Urban Agglomeration, offering important references for the optimization of regional development strategies and policy formulation.

The commodification of rural space is a crucial strategy for promoting the transition and reconstruction of rural space,as well as rural revitalization. This article analyzes the development process and laws of rural spatial commodification according to the analytical framework of "concept identification-types and characteristics-evolution stages and driving factors-effects and inspirations",and puts forward the enlightenment of rural spatial commodification on rural revitalization in China. The results show that: 1) There are certain differences in the rural spatial commodification between China and developed countries in Europe and America. These differences primarily stem from variations in rural spatial ownership,organizationalmodels,economic systems and development paths. These types can be divided into five primary categories,including land elements,agriculturalproducts,ruralindustry,ruraltourism,and rural trade. The development process exhibits distinct phased characteristics with noticeable spatial differentiation among the eastern coastal area,the central region and the western region. 2) Driven by both endogenous development needs and external environment factors,rural areas are increasingly engaged in the production of material and non-material space. This trend has led to a phased evolution of rural spatial commodification with a continuous improvement in its degree. 3) The rural spatial commodification has positive effects such as promoting the multifunctional transformation of rural areas,improving the efficiency of rural land use,diversifying the livelihoods and increasing income of farmers,inheriting and protecting agricultural culture,integrating rural industries,narrowing the urban-rural gap,and promoting social and cultural exchange and integration in rural areas. However,it also leads to creative destruction of rural space,the strong profit sharing of urban capital entities has negative effects on ordinary farmers,such as exclusion and fragmentation of existing social relationships in rural areas. 4) Promoting the commodification development of rural space is an important means to promote industrial prosperity and tap into the potential of rural consumption in the implementation of the rural revitalization strategy. However,it is necessary to introduce relevant policies,improveplanning,strengthensupervision,and prevent the negative impact of commodification of rural space.

Base on the panel data of 28 cities in urban agglomerations of the middle reaches of the Yangtze River, this article empirically investigates the spatial effects of new-type urbanization affecting regional high-quality development from 2011 to 2022 adopting the entropy weight method, OLS model and spatial Durbin model. The results show that: 1) The new-type urbanization and regional high-quality development level centered on the three provincial capital cities of Wuhan, Changsha and Nanchang show a spatial pattern that radiates to the surrounding areas, and there is a significant development gap among different regions. 2) New-type urbanization has a significant role in promoting regional high-quality development,the improvement of financial development level,economic agglomeration levle and infrastructure level has a significant positive impact on regional high-quality development,while the improvement of informatization level and government intervention level has a significant negative impact on regional high-quality development. 3) The impact of new-type urbanization on regional high-quality development of urban agglomerations in the middle reaches of the Yangtze River has a significant spatial spillover effect, and the promotion of local high-quality development is stronger than the impact on neighboring regions.

It is an urgent practical problem to coordinate the spatial conflict between production,living and ecological (PLE) and to optimize the territorial space in the current academic frontier and territorial space planning. Based on an overview of the research progress on spatial conflict and conflict risk, this article preliminarily establishes the logical main line of the research on PLE space conflict risk by focusing on the construction of basic theories,identification and evaluation,driving mechanism,optimization and regulation. It combines with the multi-function of land use and the framework of social-ecological system(SES),and deeply analyzes the formation mechanism of PLE space conflict risk and its occurrence from the dimensions of management-control and spatial form. This article condenses the conceptual connotation of PLE space conflict risk,and establishes the classification system of PLE space conflict risk. In the construction of the method system,this paper puts forward the assessment path of the PLE spatial conflict risk,the research path of the PLE space conflict risk driving mechanism and the PLE space optimization path based on the conflict risk. In the future, it should start from strengthening the research on PLE spatial conflict risk in small and medium-sized space units,and strengthen the research on PLE spatial conflict risk in the aspects of in-depth exploration of the application scenarios of PLE spatial risk in territorial space plans, and the development of intelligent supervision platform of PLE spatial conflict risk.

This article aims to explore the intrinsic connection and mechanism between new quality productive forces and high-quality development of the tourism industry. It firstly defines the concepts of new quality productive forces and high-quality tourism development,and analyzes the logical relationship between them. On the basis of the above, this article further explores the application scenarios of new quality productive forces in the tourism industry, including scenario innovation, service model transformation,and the construction of a unified scheduling platform. It's found that new quality productive forces play a key empowering role in the high-quality development of the tourism industry through innovation driven factor allocation, structural optimization of digital technology, production synergy of institutional change,and green development effects of spatial aggregation. Based on the above, this article proposes strategies, such as building a dynamic management intelligent platform,optimizing the allocation of cultural and tourism resources,strengthening digital connectivity between regions, and adhering to low-carbon and green development, in order to promote the high-quality and sustainable development of the tourism industry.

Based on the panel data of China's inter-provincial from 2010 to 2020,this paper uses the entropy method to measure the common prosperity level in China,and the modified gravity model and social network analysis to explore the spatial correlation network structure characteristics and driving mechanism. The results show that: 1) In 2010-2020,the common prosperity level showed a gradually decreasing gradient from the east of China to the west of China,and the optimal equilibrium degree of the common prosperity level in the north-south direction was higher than that in the east-west direction. 2) The spatial correlation of common prosperity was becoming closer at the provincial level,the spatial network structure was complicated,multi-threaded, and dense, and the spatial correlation flow was "strong in the east of China and weak in the west of China". Beijing, Shanghai, Jiangsu, Zhejiang and other provinces occupied the core position in the spatial correlation network of common prosperity, controlling and influencing the external radiation and spatial spillover of common prosperity level, while Tibet, Xinjiang, Qinghai and other provinces had less influence in the network,and were in the marginal position, difficult to control and influence other regions. 3) Spatial adjacency relation,the difference in economic development level, the difference in urbanization level, and the difference in the degree of opening to the outside world jointly drove the optimization and evolution of the spatial correlation network structure of common prosperity.

Based on the upstream and downstream supply flows between enterprises, this paper identifies the biomedical industry chain, and uses kernel density analysis, locational quotient method, OD analysis method to reveal the spatial pattern of the biomedical industry chain in Wuhan metropolitan area and explore its spatial organization model. The results show that: 1) The distribution of enterprises in each link of the biomedical industry chain based on site space presents diversified characteristics of core agglomeration, node agglomeration and axis agglomeration in Wuhan metropolitan area. 2) Based on the functional network, the correlation of enterprises in each link of the biomedical industry chain presents a complex pattern of local near-domain association, hierarchical radiation association, and long-distance association in Wuhan metropolitan area. There is a certain pattern of spatial correlation between enterprises in multiple links of the biomedical industry chain, which shows the characteristics of the short-distance migration of the core-near-domain from the front-end to the midstream link, the periphery-near-domain convergence reshoring from the upstream to the midstream link, and the near-domain-global two-way output from the midstream to the downstream link. 3) The biomedical industry chain in Wuhan metropolitan area follows the basic pattern of circle layout, including specific characteristics such as functional synergy, circle coordination, decreasing value-added capacity, and traffic series circle penetration.

Urban and rural areas have the relationship of mutual promotion and mutual symbiosis. Whether the urban-rural relationship can be handled well is related to the overall socialist modernization construction. Accelerating the integrative development of urban and rural areas and promoting the common prosperity of urban and rural areas are not only the inherent requirements of Chinese path to modernization,but also a major measure to organically combine the new type of urbanization with the overall rural revitalization.

It will accelerate the formation of a new type of relationship between industry and agriculture,which includes mutual promotion of industry and agriculture,urban-rural complementarity,comprehensive integration,and common prosperity. It puts forward some policy suggestions that are gradually achieving the equality of basic rights and interests between urban and rural residents,the equalization of urban and rural public services,the balance of income between urban and rural residents,the rationalization of urban and rural factor allocation,and the integration of urban and rural industrial development.

Based on the panel data of 180 prefecture-level and above cities in China from 2010 to 2019,this paper uses the quasi-natural experiment of "Broadband China" policy and instrumental variables such as "the shortest distance between a city and a national backbone direct connection point" to discuss the influence of information infrastructure on employment rate of labor force,employment structure,and industrial structure. The results show that: 1) Information infrastructure can improve regional employment. 2) Internet access can promote the upgrading of regional employment structure and significantly promote the increase in the proportion of employment in the tertiary industry. It also significantly has a positive impact on the density of newly registered enterprises in the region and this impact has regional differences. Overall,the construction of information infrastructure is conducive to the transformation and upgrading of regional industrial structure. In light of the findings,this paper proposes to further strengthen the construction and promotion of information infrastructure in the northeastern, central, and western regions,to promote the transformation and upgrading of regional employment and industrial structure, to provide more job opportunities and higher quality jobs for local residents.

This paper explores the theoretical logic of rural tourism promoting rural revitalization based on the ecological-production-living space theory,constructs a performance measurement index system of rural revitalization,measures and analyzes the performance of rural tourism promoting rural revitalization applying entropy-weighted TOPSIS method and natural breakpoints method,and adopts fuzzy-set qualitative comparative analysis to further analyze its influencing factors. The results show that: 1) As a whole,the performance of China's rural tourism promoting rural revitalization varies greatly between regions,showing a decreasing pattern from the eastern region to the western region. 2) According to the spatial sextile map of 2010-2022,the areas with high-level performance show a shift from point-like dispersion to agglomeration distribution pattern,the performance levels of some prefecture-level cities show a fluctuating trend. 3) In terms of the rural tourism types,the stronger location radiation effects in the eastern region obscure the impact of rural tourism types on rural revitalization performance,and the scenic area-dependent type in the western region and the cultural heritage type in the central region have greater revitalization performance. 4) In terms of the grouping analysis of influencing factors,the interaction of nine influencing factors forms four types of high-level and low-level revitalization performance grouping path modes,namely,"guarantee type of support condition","consolidation type of cultural foundation", "limitation type of source market" and " defective type of environmental quality assurance". Based on the above results,this paper proposes the enhancement path of rural revitalization under tourism practice from five dimensions: government, industry, market, enterprise and community.

As an emerging agricultural model,the rice-crayfish co-cropping model is considered as a powerful attempt to achieve sustainable agricultural development. This study aims to explore the impact of the rice-crayfish co-cropping model on the comprehensive development benefits in local area from the perspective of the three-dimensional system of food security,economic development,and ecological protection. Taking Qianjiang City of Hubei Province as the study area,it constructs an evaluation index system of the comprehensive development level of food security,economic development and ecological protection,reveals the spatio-temporal changes of the comprehensive benefits of the three-dimensional system of food security,economic development and ecological protection in each township of Qianjiang City from 2016 to 2020 under the rice-crayfish co-cropping model,and explores its obstacle factors by the means of Kernel density estimation method,comprehensive evaluation model and obstacle degree model. The results showed that: 1) Under the rice-crayfish co-cropping model,the three-dimensional system development index of Qianjiang City showed a dynamic evolution during the "13th Five-Year Plan" period,and there were some absolute differences in each township's development level. 2) The comprehensive development benefits of the three-dimensional system show a decreasing trend with higher benefits in the west,east,and north of Qianjiang City than that in the center of Qianjiang City,economic development benefit and comprehensive benefits are more consistent with the spatial and temporal changes,while food security benefits and ecological protection benefits have opposite trends. 3) Economic development indicators have the greatest impact on comprehensive development benefits,followed by ecological protection indicators and food security indicators.

Achieving common prosperity for all people is an essential requirement of Chinese modernization. It is very important to promote common prosperity by taking county as the carrier and constructing the spatial pattern supporting the development of common prosperity. This paper constructs an evaluation index system of county-level common prosperity including three aspects: development,sharing and sustainability. It takes Zhejiang Province,which is a demonstration zone of high-quality development and common prosperity,as the research object to carry out the spatiotemporal evaluation of county-level common prosperity, and puts forward the optimization plan of the development pattern and the multi-level strategy of promoting the common prosperity. It's found that: 1) During the study period,the level of county-level common prosperity and its three aspects are both improved in Zhejiang Province. Among them, it has big gap in terms of the level of county-level common prosperity and the level of sharing,the gap has narrowed in terms of the development level,the wave shape of sustainability level has changed from unimodal distribution to multi-polar differentiation. 2) The level of county-level common prosperity is high in the north of Zhejiang Province and low in the south of Zhejiang Province. Comparing with other regions in Zhejiang Province,there is still a big gap in the level of common prosperity of the 26 counties in mountainous areas, which is the short board in the construction of common prosperity demonstration zone in Zhejiang Province. 3) There is an obvious disequilibrium line. In order to solve the unbalanced development situation on both sides of the disequilibrium line,it is suggested to build the main axis of supporting the balanced development of Zhejiang Province: Cixi-Qingyuan line,and build the common prosperity development pattern of "two lines, four districts and four cores" based on the Lin'an-Xiangshan line and Cixi-Qingyuan line,so as to to provide spatial support for the development of demonstration zones for common prosperity in Zhejiang Province.

Based on the panel data of 108 prefecture-level cities in the Yangtze River Economic Belt from 2011 to 2020,this study applies the coupling coordination degree and PVAR model to analyze and explore the coupling coordination relationship between digital economy and urban-rural integration development. The results show that: 1) The relationship between digital economy and urban-rural integration development basically realized the transformation from mildly dysfunctional to basically coordinated in 108 prefectural-level cities of the Yangtze River Economic Belt from 2011 to 2020,among which the digital economy and urban-rural integration development of provincial capital cities always maintain a high degree of coupling coordination and have a strong radiation-driven effect on the neighboring prefecture-level cities. 2) In terms of the coupling coordination degree between digital economy and urban-rural integration development in different regions,cities in the lower reaches of the Yangtze River are higher than that in the upper reaches of the Yangtze River,followed by cities in the middle reaches of the Yangtze River. Among them,cities in the lower reaches of the Yangtze River have been in the lead for a long time, cities in the middle and upper reaches of the Yangtze River were basically comparable in 2011-2016,but cities in the upper reaches of the Yangtze River have been significantly higher than that in the middle reaches of the Yangtze River since 2017. 3) At present,it has not formed a long-term positive interactive relationship between digital economy and urban-rural integration development in prefecture-level cities of the Yangtze River Economic Belt. Specifically,the development of urban-rural integration promotes the growth of the digital economy,while there is obvious regional heterogeneity in the role of the digital economy on the development of urban-rural integration. Among them,it has a short-term promotion effect on the urban-rural integration development in prefecture-level cities of the upper and lower reaches of the Yangtze River,but has a certain negative impact on the urban-rural integration development in prefecture-level cities of the middle reaches of the Yangtze River. Therefore,in order to realize the optimal solution of digital economy and urban-rural integration development,underdeveloped prefecture-level cities in the upper reaches of the Yangtze River should focus on development issues and enhance the economic development momentum. The prefecture-level cities in the middle reaches of the Yangtze River should make up for the short boards of development and create the growth poles of digital economy development. The developed prefecture-level cities in the lower reaches of the Yangtze River should focus on the issue of regional coordination,and coordinate the promotion of the regional digital economy development.

Based on the basic logic and internal relationship of the value realization of ecological products in national parks,this paper proposes the mechanism and model of the value realization of ecological products in national parks according to the logic of "product type-core mechanism-implementation method-goal orientation". The value realization mechanism of ecological products in national parks mainly includes value compensation mechanism and agency mechanism, the value realization models of ecological products in national parks mainly include franchise model,brand value-added model,ecological compensation model,mortgage loan model for easement income, and carbon sink trading model,which is to enrich the franchise business models of national parks through ecotourism,science popularization education, and other means, achieve national park brand value-added through standardized production and information technology,promote ecological compensation through differentiated compensation and institutional guarantees, improve the green financial product system of national parks through mortgage and pledge of servitude rights,and promote the conversion of carbon sink value through project development and indicator certification. Therefore,it should improve the mechanisms and models for the value realization of national park ecological products from the aspects of classification compensation,benefit sharing, factor flow,and digital empowerment, in order to form a systematic and complete national park value compensation and agency system,and promote the scientific protection and rational utilization of natural resource assets,as well as the realization of multi-dimensional value of national park ecological products.

On the basis of identifying the population growing and shrinking areas in Northeast China, and evaluating the transportation supply level in multiple dimensions, this paper conducts a comprehensive analysis framework of the influencing mechanism of transportation supply level change. Based on this framework, it discusses the regional differentiation and spatiotemporal evolution characteristics of transportation supply level in Northeast China under the background of population shrinkage, and explores the influencing mechanism of population growth and shrinkage on the change of transportation supply level. The results indicate that: 1) From 2013 to 2020, the transportation supply level in population shrinking areas of Northeast China was always significantly higher than that in population growing areas. The transportation supply shortage was prominent and intensified in population growing areas, the transportation supply tended to be moderate in slight shrinking areas, and that in severe shrinking areas was seriously mismatched and tended to be oversupplied. 2) The increase of the average annual population change rate promotes the improvement of the transportation supply level in population shrinking areas, but has no significant effect on population growing areas. Good natural conditions and high public service level promote the improvement of the transportation supply level in Northeast China, while financial capacity is manifested as a restraining effect. There are regional differences in the impact of industrial development on the improvement of the transportation supply level. The increase of regional area inhibits the increase of the transportation supply level in population shrinking areas, while the influence of regional conditions also has regional difference. 3) The increase in regional population and factor flow demand caused by rapid industrial development is the main reason for the shortage and degree aggravation of the transportation supply in population growing areas. The change of the transportation supply level is mainly due to the reduction of transportation demand caused by population loss and sluggish industrial development in population shrinking areas.

High-tech enterprises have become important drivers of regional innovation activities,exhibiting spatial agglomeration characteristics. This study utilizes methods such as spatial autocorrelation,kernel density analysis,standard deviation ellipse,and multiscale geographic weighted regression(MGWR) model to investigate the distribution characteristics and influencing factors of high-tech enterprises in Beijing. The results indicate that: 1) The spatial autocorrelation of high-tech enterprises in Beijing initially increased and then weakened,with the overall spatial pattern showing little change and trending towards a stable stage of development. Different types of enterprises exhibited distinct clustering characteristics and each had their specific high-density clustering areas. 2) The multiscale geographic weighted regression model can adjust weights at different spatial scales,revealing the heterogeneity of high-tech enterprises at various scales more precisely. 3) Various factors exerted varying degrees of influence on the distribution of high-tech enterprises,displaying spatial heterogeneity. There were significant differences between the regression results of the MGWR model's global influencing factors and those obtained from classifying the enterprises by type. The research findings can provide a scientific basis for governments and enterprises to formulate scientific and reasonable industrial planning and innovation policies,guiding the high-quality development of the urban economy.

Urban-rural common prosperity is the key path to achieve the goal of common prosperity in Chinese-style modernization. This study proposes an evaluation framework,based on the policy agendas of co-construction,sharing,and mutual prosperity,to assess the level of urban-rural common prosperity of urban agglomerations in middle reaches of the Yangtze River from 2011 to 2020. It analyzes the spatiotemporal evolution and regional differences of urban-rural common prosperity of urban agglomerations in middle reaches of the Yangtze River by the means of entropy method,spatial autocorrelation,and Dagum Gini coefficient. The results show that: 1) The overall level of urban-rural common prosperity exhibited a complex "rise-fall-rise" trend in 2011-2020. Wuhan metropolitan area displayed a significantly higher level of urban-rural common prosperity than other regions,while the rank and level of urban-rural common prosperity fluctuated widely from year to year,high-value regions were sparsely distributed,it showed a "collapse" phenomenon in the marginal areas of urban agglomerations. 2) There were no significant spatial clustering patterns or radiation effects within the urban agglomeration. 3) Regional differences of urban-rural common prosperity level were relatively obvious,mainly due to the gap between Wuhan metropolitan area and Changsha-Zhuzhou-Xiangtan metropolitan area. Based on the research conclusions,it puts forward policy recommendations from the aspects of industrial revitalization,service sharing,resource integration and spatial cooperation.

The continuous and rapid growth of the digital economy has become an important force to promote the high-quality development of China's manufacturing industry. Based on the panel data of 41 cities at the prefecture level and above from 2012 to 2021 in the Yangtze River Delta urban agglomeration,this paper analyzes the spatial-temporal evolution characteristics of the coupling coordination between the digital economy and the high-quality development of manufacturing industry and its influencing factors using the coupled coordination model and the spatial Durbin model. It' found that: 1) The degree of coupling coordination between the digital economy and the high-quality development of manufacturing industry continues to strengthen. In terms of temporal evolution characteristics,it shows a highly coupling coordination development trend between the digital economy and the manufacturing industry in the Yangtze River Delta urban agglomeration,and has obvious regional differences. 2) There are great differences in the coupling coordination level between the digital economy and the manufacturing industry in different regions,and there is a large room for improvement. From the perspective of spatial evolution,the proportion of high-quality coordination,good coordination and intermediate coordination is very low,and there is still much room for improvement. From the perspective of spatial correlation, there is a significant spatial correlation,which is embodied in the characteristics of spatial agglomeration. 3) The coupling coordination degree between the digital economy and the manufacturing industry affects each other and has some differences between neighboring cities. Among them,the level of economic development,the level of financial development,the utilization level of foreign capital and the optimization of industrial structure have a significant positive promoting effect on the coupling coordination degree of neighboring areas,the government intervention and the degree of opening to the outside world have a significant inhibiting effect on the coupling coordination degree of neighboring areas,while human capital fails the significance level test. According to the above,it proposes some suggestions: strengthening the top-level design,radiation drive and support capability,and providing impetus for the coupling coordination development between the digital economy and the high-quality development of manufacturing industry in urban agglomerations.

On the basis of clarifying the mechanism of cultural ecosystem services(CESs) promoting cultural and tourism integration,this article takes Lyushunkou District of Dalian City as a case area,based on the POI data and social media data,and applies MaxEnt model and bivariate spatial autocorrelation analysis to quantitatively analyze the development status of cultural tourism integration. Combined with the image and sentiment analysis of online review data,it explores the spatial changes of cultural and tourism integration in the improvement of environmental factors,and proposes management suggestions to promote the development of cultural and tourism integration. The results show that: 1) The coverage ratio of recreational services in the region is significantly higher than that of cultural heritage services. It has a higher level of cultural and tourism integration in central and southwestern regions,accounting for 16.06% of the total area. 2) The main perceptions of tourists in Lyushunkou District are four aspects: landscape quality,recreational behavior,emotional experience and scenic spot management,the main factors leading to negative emotions include imperfect infrastructure,low transportation convenience,and poor professionalism of staff. 3) The road traffic opening between Dalian and Lyushunkou District has a significant effect on improving the level of cultural and tourism integration in Lyushunkou District. The coverage and volume of cultural heritage services and recreational services have increased significantly,and the area of areas with a high level of cultural and tourism integration has increased by 4.11%. Revealing the close relationship between public perception and cultural tourism integration from the perspective of CESs can provide theoretical and empirical support for improving people's livelihood and well-being and realizing the modernization of harmonious coexistence between man and nature.

Maritime service is the link to realize trade circulation and economic globalization. Distinguishing the actual status of maritime service trade in various countries is of practical significance to promote the virtuous cycle of trade and the stable development of shipping industry,and quantitatively identify the pattern and characteristics of maritime service trade. Therefore,this article uses the social network method to explore the topological characteristics and evolutionary laws of the global maritime service trade network. The results show that: 1) In terms of the evolution of network structure characteristics,the network density increases from 0.143 to 0.241 during the sample period,and the network of maritime trade services tends to be complicated and dense,with the characteristics of core edge hierarchy,small world and polarization,while scale-free is not obvious. The Pearson correlation coefficients of node degree and strength degree are -0.4780~-0.3930 and -0.0206~-0.0155,respectively. The trade network of maritime service is a typical heterogeneous network. The frequency of appearance of GCX,F8X,and FKX motifs is relatively high in each year,export structure and reciprocal structure are the important modes of maritime service trade,while highly centralized trade mode is not prominent. 2) From the perspective of each country's network status and role,core countries such as the United States,Germany and Japan play an absolute leading role in the network,South Asia is a low-value trade agglomeration area,it shows a spatial pattern dominated by Europe,Asia and North America. The node degree centrality of China and India is gradually improved,and the network status of emerging economies is obviously enhanced. Singapore is the hub of maritime service trade,Germany and the United States are major exporters of maritime service trade,Japan,the United Kingdom and Thailand tend to assume the role of import initiator,and China as the core country and intermediate node plays an important role in transmission.

The supply imbalance between cities drives population movement to other cities to meet their needs. In the early stages of China's reform and opening-up,the primary supply-demand relationship between population and cities was centered on the population's demand for economic development and the supply of urban labor markets. Once individual labor income meets the production,investment,basic consumption,and basic security needs of individuals or families,the population's demands begin to diversify. Consequently,the supply capacities of cities in terms of consumption,entertainment,landscapes,and transportation start to exert push-pull forces on population flow. This paper leverages Tencent's location big data to construct a population cross-region flow network. It uses the QAP regression model to analyze various supply factors influencing population flow in the process of population movement,and explores the hierarchical and temporal heterogeneity of population flow. The study reveals the following findings: 1) Railway transportation,catering and entertainment,and economic supply are the main factors affecting inter-city population flow,with landscape supply showing sensitivity to time choices. 2) Mobile populations have different demands for cities at different levels,with financial elements showing a diminishing marginal effect by level. However,the supply of catering,entertainment,and railway transportation does not exhibit significant hierarchical heterogeneity. 3) Population flow shows temporal heterogeneity. During holidays,landscape supply shows a significantly positive effect on the population flow,while the significance level for economic supply noticeably decreases.

The article empirically examines the spatial effect of AI application on green innovation using the spatial Durbin model with panel data of the three major urban agglomerations of the Yangtze River Economic Belt from 2011 to 2021 as a sample. The results show that:1) There is a significant positive spatial correlation between the level of AI application and the level of green innovation in the three major urban agglomerations of the Yangtze River Economic Belt,while the Moran's I value of the level of green innovation shows the characteristic of distance weakening. 2) Within the three major city clusters of the Yangtze River Economic Belt, the application of AI can significantly promote the local green innovation level to generate a "digital dividend",but the negative spillover to the green innovation level of its neighbours exacerbates the "digital divide", and this relationship is significantly varied with the difference of geography and location. This relationship changes significantly with geographic location differences. In addition, further analysis reveals that there is an "inverted U-shape" relationship between the local and spillover effects of AI applications on the level of green innovation, in which the local and spillover effects are first promoted and then suppressed. 3)The analysis of spatial effect decay found that the negative spillover effect of AI applications on green innovation level showed a geographic distance decay trend,and the maximum spillover decay boundary was reached at 450 km. Digital inclusive finance and digital industrial agglomeration have a significant moderating role in the "inverted U-shape" relationship between the level of AI application and the level of green innovation. Focusing on the dual perspectives of AI and green innovation,we provide theoretical support and empirical evidence for promoting China's green,low-carbon and cyclical development.
