Green innovation is the driving force of greening transformation and high-quality development,just as innovation is the driving force of development. Based on the green innovation research literatures in the field of economic geography from 1990 to 2019 in the Web of Science and CNKI databases,this paper uses bibliometric analysis and a review of relevant literatures at home and abroad with the help of Citespace software to systematically sort out the theoretical development lineage and hot topics of green innovation research,clarifies the research frontier and academic controversies,and aims to seek a breakthrough for the construction of the theoretical system of green innovation in China. From the perspective of economic geography,it's found that: 1) The research lineage has mainly experienced the development from focusing on the connotation and characteristics of green innovation itself,to attaching importance to external influences,driving effects and the relationship between cross-regional knowledge interactions and green innovation,and then to the current research on the characteristics of inter-firm and inter-city innovation networks and their spatial evolution characteristics around green innovation. 2) The research focuses on knowledge linkages and spatial impacts at the micro-firm and city levels. 3) The research hotspots include the double spillover effect,triple bottom line,multiple driving effects and path dependence of green innovation. 4) The research paradigms focus on the influence of geographical location,the evolution of flow-spatial networks and the synergy of innovation systems. The research proposes that: Firstly,the future research direction of green innovation is to explore the balance point of green innovation investment under different positions,so that green innovation can conform to policy logic and market logic at the same time to the greatest extent. Secondly,it should explore the impact of green innovation under the policy push/pull effect based on multi-dimensional proximity. Thirdly,based on the background of China's current green development strategy and the "double carbon" target,it should explore an efficient and appropriate green innovation system with Chinese characteristics.

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.

Improving the ability of the economic system to respond to internal and external shocks is of great significance to the high-quality development of the regional economy. The spatiotemporal correlation characteristics and dynamic evolution mechanism of China's regional economic resilience from 1997 to 2020 were systematically observed in this study by constructing an economic resilience index and using Theil index, spatial analysis, geographic detectors and other methods. The results showed that: 1) During the study period,China's regional economic resilience generally showed a W-shaped dynamic fluctuation and upward trajectory, about 65% of the provinces were in a state of moderate resilience, and the disequilibrium characteristics at the regional level were gradually strengthened. Inter-provincial differences were the main components of spatial differences in economic resilience. 2) The spatial correlation of regional economic resilience had a typical evolutionary trend in stages, and economic resilience in space gradually showed a positive agglomeration correlation. The locally-related cold and hot spots patterns were directly affected by the type and scope of the shock,showing significant inter-provincial heterogeneity. 3) The spatiotemporal evolution of economic resilience was driven by the common interactive complex factors, and the evolution pattern of resilience collaborative dominated by effective market and competent government was gradually established. The guiding role of innate factors such as geographic location was becoming more and more diverse. Financial support and technological innovation were effective drivers for the improvement of the regional economic system's risk adaptability. Urban development and government management were the main paths and played an important role in the occurrence of multi-dimensional linkage effects.

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. Based on the analysis of the current imbalance of urban-rural development in China,this article proposes to improve the system and mechanism for promoting the new type of urbanization,consolidate and improve the basic rural operation system,improve the support system for strengthening agriculture,benefiting farmers and bringing prosperity to farmers,deepen land system reform,accelerate the establishment of the system and mechanism for integrative development of urban and rural areas,comprehensively improve the integration level of urban-rural planning,construction and governance,promote the equal exchange and two-way flow of urban and rural elements,constantly narrow the gap between urban and rural development. 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.

This paper constructs an index system for measuring the resilience of industrial chains from the four aspects which are resistance,recovery,evolution and government power,and builds a model for measuring the resilience of industrial chains based on the dynamic combination-TOPSIS method. On this basis,this paper measures the resilience of 14 manufacturing industry chains in China as a whole and in the eastern,central and western regions in 2011-2020 using data from listed companies,and analyzes the spatial differences and evolution patterns of the resilience of manufacturing industry chains using the methods of Kernel density estimation,Dagum Gini coefficient decomposition and σ convergence. The results show that: 1) there are differences in the resilience level,driving factors and weak links of each manufacturing industry chain in China,among which the resilience is relatively large in terms of the energy,transportation equipment manufacturing and metal products industry chains,while the resilience is smaller in terms of the textile,clothing and apparel,papermaking,education and sporting goods and other manufacturing industry chains. 2) According to the change of the resilience of the industry chains,China's manufacturing industry chains can be divided into three types: benign fluctuation type,fluctuation-reversion type and fluctuating decline type,while the development of most manufacturing industry chains belongs to the benign fluctuation type. 3) The toughness of China's manufacturing industry chains shows obvious spatial and temporal divergence. The toughness of manufacturing industry chains in the eastern and western regions both have an upward trend,while the central region has a downward trend. The gap between regions in the resilience of manufacturing industry chains has a tendency to expand. In order to enhance the resilience of China's manufacturing industry chain and alleviate the regional disparity,this paper puts forward policy suggestions for consolidating and strengthening the chain as well as promoting coordinated development among regions.

Quantitative spatial economics using structural estimation to closely integrate “big models” and “big data” has great theoretical contribution and extensive application prospects, and has become a new trend in studies of spatial economics. This paper explores the internal unity of gravity equations and equilibrium equations in quantitative models of trade, migration and commuting. reviews the frontier progress in identifying the network effects of exogenous shocks from the perspective of spatial general equilibrium and quantifying the aggregate and differential effects of exogenous shocks through counterfactual simulation. Lastly, it summarizes the academic innovation values of quantitative spatial economics from the heteromorphism and isomorphism of several mainstream models to quantitative methods including structural estimation and counterfactual simulation, prospects its future development directions, and emphasizes the significance of general equilibrium for the analysis of spatial economic issues so as to provide reference for Chinese scholars to narrate compelling China stories about spatial economic development in the new era.

With the deepening of economic globalization,new urbanization and rural revitalization strategies,urban-rural relations have entered a new stage of urban-rural integrated development. Different from the traditional urban-rural relationship,urban-rural integrated development takes the two systems of the urban and the rural area as a whole,emphasizing the multi-level,multi-field and all-round penetration and integration,the urban-rural geographic system has increasingly become an important research object in the field of geography. Geographers at home and abroad are committed to the construction of urban-rural integrated development theory,and carry out the research on the evaluation and measurement of urban-rural integrated development,the driving factors and mechanisms of urban-rural integrated development,the effect of urban-rural integrated development,and the realization path of urban-rural integrated development based on the geographical logic of "pattern-process-mechanism-effect-control". Theoretical discussion and empirical analysis have made relatively rich research results,but there are still problems such as insufficient integration of the perspectives of urban-rural integrated development,insufficient analysis of mechanism mechanisms,insufficient attention to new trends,and lack of innovation in research methods. In the future,it should strengthen the researches on the temporal and spatial heterogeneity and dynamic mechanism of urban-rural integrated development,multi-scale/multi-type regional space urban-rural integrated development,integrated application of new technologies,and the relationship between "dual carbon" and urban-rural integrated development.

The resilience assessment of rural settlements in tourism areas is an important path to quantify the resilience level,identify internal differences,reveal potential risks,and promote the cultivation of resilient villages and sustainable development of rural tourism. Based on the analysis of resilience concept,this study constructs the "absorption-adaptation-transformation" framework of rural settlement resilience assessment in tourist destinations. Taking Enshi as an example,the comprehensive index method and geographic detector are used to measure and identify the resilience level and risk factors of rural settlements at the community and farmer scales. The scale correlation is explored from four aspects: overall trend,index distribution,rank correspondence and risk factors. The results show that: 1) At the community scale,the overall resilience of rural settlements in Enshu is moderate,and the higher the maturity of rural tourism development,the higher the resilience level. 2) At the household scale,the proportion of farmers with medium resilience level is the highest (43%),the proportion of farmers belonging to the type of part-time livelihood has the highest resilience level,and the proportion of farmers belonging to the types of labour/agricultural livelihoods is the lowest. 3) Different risk factors have different effect on the resilience of rural settlements,common factors and difference factors co-exist between scales,and resilience risk barriers are focused with scale refinement. 4) The overall resilience pattern has some continuity and consistency across multiple scales,the distribution of index values gradually shifts towards concentration as the scales are refined,and there is a clear correspondence between scales in terms of resilience index levels,and as the maturity of community tourism development increases,the resilience of farmers' livelihoods also increases significantly.

Rural gentrification is a phenomenon of rural social space reconstruction caused by population mobility, which is deeply characterized by class connotations, institutional context and spatiotemporal heterogeneity, it is an important topic of western geography and has gradually entered the research field of Chinese geography. Based on the geographical logic of "concept-process-pattern-mechanism-regulation",this paper analyzes the research progress of the concept evolution,evolution process,spatial pattern,occurrence mechanism and effect regulation of rural gentrification. The existing research has initially formed the concept, tools and theoretical system of rural gentrification, has begun to take on the research characteristics of multiple methodologies and theoretical schools,and the differences in spatiotemporal context call for comparative research and theoretical dialogue. Guided by the theory of human-environment interaction territorial system, scale thought and comprehensive thinking, and the main line of "human life-environment change-human and environment interaction", this paper constructs a geographical research framework for rural gentrification, and deepens the geographic research theme of rural gentrification in Chinese context.

This paper clarified the scientific connotation and forms of the flow of urban-rural land elements,and explored the spatial-temporal pattern and driving mechanism with the methods of statistical analysis,GIS spatial analysis and spatial econometric model. The results show that: 1) The flow of urban-rural land elements is the process of realizing the value transformation of land elements through ownership change and function transformation in rural-urban territorial system. The main forms include land expropriation,linkage between urban-land taking and rural-land giving(LUTRG),transaction of rural commercial collective-owned construction land and land consolidation. 2) From 2004 to 2017,the flow of urban-rural land elements shows the tendency that first increased with fluctuation,and then continuous,and the spatial distribution is high in the west of China and low in the east of China,and high in the middle of China and low in the north and the south of China. 3) As the result of market-driven and government intervention mechanisms,urban-rural income gap,urbanization rate,non-agricultural income and land financial dependence promote the flow of urban-rural land elements,while urban-rural land comparative benefit has a negative impact. 4) It is the key to rethink the multiple values of land elements and improve income distribution mechanism of land factor appreciation that favor rural territory. Optimizing the pattern and type of urban-rural land element flow is the key content in the future.

Livelihood space is an important carrier for farmers' livelihood practices. Promoting the optimization and reconstruction of livelihood space for relocated farmers is not only the key to achieve their sustainable livelihoods,but also an inevitable requirement for promoting rural revitalization. This paper constructs the evaluation index system of livelihood space quality of relocated farmers from the four dimensions of life,production,society and institution. Based on the data of household survey and in-depth interview in the Longnan mountainous area,this paper evaluates the improvement effect of poverty alleviation relocation on farmers' livelihood space,identifies the key obstacles affecting the quality of livelihood space,and reveals the impact mechanism of poverty alleviation relocation on farmers' livelihood space. The results show that: 1) In the initial stage of resettlement,the effect of poverty alleviation relocation on farmers' livelihood space is general,and only about 35% of farmers believe that the improvement effect of livelihood space is better. 2) From different dimensions,the improvement effect of poverty alleviation relocation on living space is the best,followed by social space,while the improvement effect on production space and institutional space is relatively poor. 3) The expansion of farmland area,compression of housing area,reduction of community participation and insufficient non-agricultural employment opportunities are the main obstacle factors affecting the improvement of livelihood space quality of relocated farmers. 4) Poverty alleviation relocation has a double-edged sword effect on farmers' livelihood space. It can not only promote the development of livelihood space in the direction of urbanization and intensification,but also lead to the development of livelihood space in the direction of disorder,marginalization and atomization. Finally,it puts forward the optimized path and countermeasures for constructing sustainable livelihood space.

Based on the five development concepts,this paper constructs an evaluation index system of the high-quality development of tourism industry from two aspects of "quantity" and "quality". Based on this,the high-quality development level of tourism industry in 30 provinces and cities in China from 2011 to 2020 is measured. With the help of absolute β convergence,kernel density estimation,NICH index and Hurst index superposition,it analyzes the spatial and temporal evolution pattern and development trend of the high-quality development of tourism. It uses the obstacle factor diagnostic model to analyze the factors affecting the high-quality development of tourism. The following conclusions are drawn: 1) During the study period,the development level of high-quality tourism in China is generally good and convergent,showing a spatial distribution pattern of "high in the east and low in the west,high in the north and low in the south",and the eastern coastal area is with high values. 2) In the future,the gap of high-quality development of tourism has a trend of narrowing between the east and the west of China,while it has a risk of widening between the south and the north of China. At the same time,the growth trend is strong in southwest and central regions,while Qinghai has a weak anti-sustainable development trend. 3) The main obstacles affecting the high-quality development of tourism are dynamic,mainly from the four aspects which are innovation drive,environmental effect,industrial structure and development efficiency,and also include the level of tourism service and the integration between cultural industry and tourism industry. Special attention should be paid to the stability of tourism development and the effect of tourism. Therefore,this paper puts forward some countermeasures to promote the development of tourism with high-quality in China from strengthening spillover effect of growth pole,regional tourism integration construction and breaking down main obstacle factors.

Studying the optimization of urban water ecological network from the perspective of resilience and improving the resilience of water ecological space are the important ways to improve the overall resilience level of cities. Firstly, the article combines the objectives of resilient city with water ecological network, and proposes to construct the water ecological space of resilient urban from three dimensions: structural resilience, functional resilience, and regulatory management resilience. Secondly, taking Changsha City as a typical case and applying MSPA model and MCR model, this article identifies and constructs the water ecological network based on the "source-corridor-node". From the perspective of integration of complex network and graph theory, the evaluation index of network resilience is constructed from the structure and function dimensions, and indicators effectively reflecting the structural resilience and functional resilience of the water ecological network are selected to evaluate the resilience of water ecological space in Changsha. The results show that: The overall connectivity of the water ecological network is at good status, a foundation of resilience is preferable, and the landscape fragmentation is manageable, but the long-term urban construction and development damage the connectivity of the water system within the city, and lead to the low-level diversity and single function of the water network. Redundant design of the network is insufficiency, dynamic adaptability of regulation and management is weak. The study further proposes the optimization strategy of the water ecological network in Changsha based on resilience enhancement: speeding up the restoration of natural water corridors and dredging the connection of existing artificial ditches, attaching importance to the implementation of "point-axis development" and multi-functional composite utilization models of ecological nodes and corridors, enhancing the redundancy and modular design of urban water network structure and function, improving the resilience of the regulation and management and forming a dynamic regulation mechanism for multi-channel disaster response.

Urban-rural integrated development is an important development orientation in China, and the county territory is the pioneer area and breakthrough point of urban-rural integrated development. Chinese path to modernization has endowed county territory with new development connotation and era mission. Urban-rural integrated development at county level needs to give full play to the node functions of transition,connection,convergence,transformation and integration of county territory. By optimizing the urban spatial system and the spatial texture of urban-rural territorial functions,urban-rural integrated development can smooth the circulation mechanism,value increment and manifestation mechanism of urban-rural elements,and promote the equal development of urban-rural territories. The key tasks of urban-rural integrated development at county level under Chinese path to modernization are to optimize the urban-rural territorial system within the county territory,accelerate the gradient citizenization of agricultural migrant population,coordinate rural vitalization and county urbanization,and promote agricultural and rural modernization. The research on urban-rural integrated development at county level under Chinese path to modernization should focus on the theoretical reconstruction and practical logic of urban-rural integrated development,the flow mechanism and optimal allocation of urban-rural development elements,the industrial division pattern and function improvement of urban-rural territories,the system scheme of urban-rural integrated development, and the methodology innovation and technology integration facing the new demands within the county territory.

Food security is the cornerstone of national security. In the current complex and volatile external environment,it is all the more important to explore the resilience of food production. Based on the panel data of 31 provinces (cities and autonomous regions) in China from 2004 to 2018,this paper constructs a comprehensive index of grain production resilience,and analyzes the spatial pattern and influencing factors of grain production resilience using the entropy method,standard deviation ellipse and geographical detector model. The results shows that: 1) From 2004 to 2020,the resilience of grain production in China showed a declining trend,and the ability of grain production to resist risks was insufficient. The resilience level was higher in central and eastern regions than that in western region,but the overall trend was downward,while the resilience level of northeast China was relatively stable. 2) Urbanization rate,science and technology factors,and price changes of agricultural means of production are the main factors affecting the resilience of grain production. The interaction between the two factors is mainly two-factor enhancement and nonlinear enhancement. Finally,the paper puts forward some policy suggestions to enhance the resilience of Chinese grain production from the aspects of promoting the development of new urbanization and grain production as a whole,actively building a new modern grain industry system,and accelerating the construction of a new grain industry development pattern.

This paper studies the short video cyberspace attention from the perspective of geography,and explores the relationship and interaction mechanism between the new virtual space and the physical space of short video production. This paper analyzes the spatial distribution of urban tourism Douyin attention by using the method of spatial distribution balance measurement,it uses the Exploratory Spatial Data Analysis (ESDA) method to analyze the spatial structure characteristics of the urban tourism Douyin attention,and the Geographically Weighted Regression model (GWR) to analyze the influencing factors of the urban tourism Douyin attention. The study shows that: 1) From the perspective of spatial distribution equilibrium,the spatial distribution of urban tourism Douyin attention in urban agglomeration has a good balance and moderate concentration degree,and the spatial distribution equilibrium of Jiangxi Province is close to that of urban agglomeration. In Hubei Province and Hunan Province,the spatial distribution of urban tourism Douyin attention is poor and the concentration degree is high. 2) From the perspective of spatial distribution characteristics,the overall pattern of urban tourism Douyin Douyin attention is "high in Wuhan and Changsha,low in cities which locate between Wuhan and Changsha and in the southwest of Jiangxi Province". 3) From the perspective of spatial agglomeration characteristics,there is a positive spatial correlation as a whole,but the degree of spatial agglomeration is low,the spatial distribution of urban tourism Douyin attention is relatively scattered. Among them,Wuhan is the high-value agglomeration area,Yiyang is the low-value agglomeration area,and other cities have insignificant agglomeration characteristics. Wuhan and Changsha are hot-spot areas. 4) From the perspective of influencing factors,the regression coefficient of e-commerce logistics level,human resource level,mobile Internet development level,economic development level and entrepreneurial environment quality are all positive with decreasing degrees of influence in turn,which all have a positive promoting effect on the improvement of urban tourism Douyin attention. Among them,the positive effect of e-commerce logistics level is the largest,and the positive effect of entrepreneurial environment quality is smaller.

Industrial agglomeration has important theoretical and practical significance to promote the high-quality growth of regional economy. This paper takes 289 cities in China from 2004 to 2021 as the research object,and uses spatial econometric model to identify the mechanism of industrial agglomeration on high-quality regional economic growth. The results show that specialized agglomeration and diversified agglomeration have spatial spillover effect on the neighboring regional economy. In terms of industrial structure,specialized agglomeration provides impetus for local development through industrial structure adjustment,but diversified agglomeration does not promote high-quality economic growth of local and neighboring regions through industrial structure adjustment. In terms of city size effect,megacities get economic effects from specialized agglomeration,large and medium-sized cities have spatial polarization effects on neighboring regions,while small cities have no significant effects on either specialized or diversified agglomeration. In terms of regional effects,it mainly obtains economic effects from diversified agglomeration in the eastern region,and the central and western regions obtain economic effects from both specialized and diversified agglomeration,while neither specialized nor diversified agglomeration is significant in northeast China.

Regional integration can effectively promote regional development by promoting inter-regional resource sharing and economic coordination. As national development strategy,Yangtze River Delta integration has become an important issue of concern in the field of economic geography. With the help of the knowledge map visualization technology to analyze the academic research status of the Yangtze River Delta region,this study explores the research progress of regional integration in economic geography based on systematic literature reading. The results show that: 1) Academic research about the regional integration of Yangtze River Delta needs further attention,more academic creativity and closer academic community. 2) Research on regional integration of the Yangtze River Delta concentrates on five aspects: industrial cooperation and spatial organization,urban division and regional development,regional transportation network and integrated high-quality development,and has formed the pattern of multi-center,layered and transportation-oriented network. Proximity,agglomeration effect,spillover effect and the influence mechanism of government game in integration act as essential impact factors in the integration process. 3) Research focus on regional integration of the Yangtze River Delta has shifted from pattern description to mechanism and countermeasures exploration,and research cognition has been constantly upgraded from emphasizing regional division of labor and cooperation,to regional coordination and to regional integration. However,due to the limitation of measurement data and methods,new interpretation of regional integration still needs further exploration and debate.

In recent years, the development of pet industry has become a phenomenal economic form, which not only reflects the changes of social economy and geographical culture, but also reflects the emotional and life needs of people in modern society. The rapid development of pet economy weaves a new network of "life emotion-economic geography" and endows pets with the dual roles of "commodities" and "consumers", not only expedites the huge industrial connection with pet breeding, diet, medical treatment and entertainment as the core, but also injects the new life relationship into the traditional economic form through the "pet +" mode, promoting the renewal of transportation, accommodation, tourism and other industries. Pet economy is based on life and emotional clues, and stimulates the huge theoretical demand. It is the urgent responsibility of the academic community to innovate and explore many of the issues, such as the diversity of pet industry and consumption behavior at the economic level, the new emotional space and human land relationship at the geographical level, the demographic change and new power at the social level, the norms and ethics of animal breeding and trading at the industrial level, the protection of animal rights and interests and the cultivation of life ethics at the institutional level, the improvement of laws and regulations and the optimization of development models at the management level. From the perspective of economic geography, the following essays integrate multi-dimensional perspectives such as cultural geography, consumer behavior and psychology, emotional space and emotional economy, animal ethics and moral economy, as well as the management policy system of pet industry to explore the diversified issues and innovation direction contained in the development of pet economy, so as to provide cutting-edge and profound thinking and judgment for this emerging huge economic form.

With the rapid development and wide application of digital technology,the digital economy has become an important economic form at present,which has an important impact on urban development and its spatial pattern. Taking Hangzhou as the case study,this paper uses the methods of the kernel density and standard deviational ellipse to analyze the evolution and distribution characteristics of digital enterprises,and explore the spatial agglomeration mechanism of their development and change. The results show that: 1) Hangzhou's digital economy has experienced three stages,including steady development stage,rapid development stage and comprehensive development stage. The distribution of digital enterprises shows the evolution characteristics of urban agglomeration,suburban diffusion and regrouping,forming a network structure centering on the three core areas of the main urban areas,Binjiang District and Yuhang District. 2) The location and spatial agglomeration of various digital enterprises show different characteristics of industry agglomeration orientation,land cost orientation,innovation ecological orientation and digital technology orientation. The development of digital technology application industry and digital factor driven industry is the most mature,forming the regional pattern of the spatial agglomeration dominated by innovation ecosystem. 3) The local government,enterprise organizations,the public and other dynamic subjects have jointly promoted the evolution of the industrial spatial pattern of digital economy,including the industrial policy guidance,the urban spatial structure adjustment,the leading enterprises' guidance,the innovation network development,the population suburbanization and the convergence of innovative talents,which have promoted the all-round development of Hangzhou's digital economy.

This paper synthesizes the four dimensions of urban economy resilience,society resilience,ecology resilience and engineering resilience to build the resilience index system of resource-based cities,uses entropy method to measure the resilience level of 114 resource-based cities in China from 2004 to 2020,and further analyzes the regional differences and influencing factors of the four types of resource-based cities. The results show that: 1) The fractal indexes of the resilience of the four types of resource-based cities in China have similar distribution,with the order of social resilience,engineering resilience,ecological resilience and economic resilience. Among them,the average value of each dimension of regeneration-type cities is in the leading position,and the decline-type and growth-type cities are relatively behind. The absolute differences show a steady downward trend in order of growth-type,maturity-type,decline-type and regeneration-type cities. 2) There are obvious regional differences in the resilience levels of four types of resource-based cities,and the main source is regional differences. In terms of intraregional differences,the intraregional differences of four types of resource-based cities are characterized by "mature-type>regeneration-type>decline-type>growth-type". In terms of interregional differences,the regional differences between growth-type and regeneration-type cities are the largest,and the interregional differences between growth-type and regeneration-type cities are the smallest. 3) Market size,scientific and technological investment,financial development,industrial structure and environmental regulation can significantly affect the resilience level of resource-based cities in China,and the intensity of the effect is heterogeneous.

Based on the theory of cultural space and taking Shenzhou events on the Dragon Boat Festival as a case study,this paper adopts the methods of geographical positioning research,literature research and field investigation to explore the living protection and inheritance of intangible cultural heritage. The research shows that Shenzhou events,as a special festival activities,that rely on the religious places of Buddhism and Taoism embodies the practice of cultural space production theory. During the development and evolution of Shenzhou events over the past 1 000 years,it reflects the dominance and changes of different religious cultures,and still remain active in certain regional cultural fields. According to the above,the protection and inheritance of intangible cultural heritage of festival activities need to be fully active protection and inheritance,not only to protect certain material basis,but also to preserve regional traditional culture.

Taking cities in the Yellow River Basin as research area,this paper divides cities into different types by using location quotient,and analyzes the spatial and temporal distribution characteristics and influencing factors of economic resilience of different types of cities in the Yellow Riviver Basin using Moran index,variation coefficient,Spearman correlation coefficient and other methods. The results show that: 1) There is a significant spatial agglomeration phenomenon of urban economic resilience when the level of urban economic resilience is close to that of other regions. There is a positive spatial correlation in cities with the leading industry of the production and supply of electricity,gas and water or agriculture,and the spatial agglomeration characteristics are obvious. 2) From 2008 to 2019,the economic resilience at different types of cities in the Yellow River Basin fluctuated greatly,and the economic resilience gap of different specialized cities in the Yellow River Basin showed a trend of fluctuation narrowing. 3) From 2008 to 2019,the top two types of cities in the Yellow River Basin in terms of economic resilience mainly belong to the cities taking the tertiary industry as the leading industry,while the bottom five types of specialization cities mainly belong to the cities taking the primary and secondary industries as the leading industries.4) For different types of cities,population density is significantly positively correlated with urban economic resilience. Except for the cities focusing the development of architectural or scientific,technological and geological exploration,financial development index are significantly positively correlated with the city's economic resilience.

The report of the 20th National Congress of the Communist Party of China regards promoting the building of the human community with a shared future as one of the essential requirements of the Chinese path to modernization,which provides new theoretical support for the innovative development of China's world economic geography theory. This paper sorts out the development process of world economic geography theory, and explains the important role of the concept of the human community with a shared future in solving contemporary complex world economic geography problems. Based on the perspective of the human community with a shared future,this article puts forward a preliminary understanding of the innovative development of world economic geography theory: world economic geography is an integrated structural concept. Global economic integration, global environmental change,and global geopolitical structure change need to stand in the perspective of the human community with a shared future,and be understood from the aspects of the global whole,the relationship between countries,the development of a country itself,non-state relations,and the interaction of subjects at different scales. World economic geography is a diachronic evolution process. The study of world economic geography should have a clear research unit,and China is an important part of the study. This article preliminarily constructs a theoretical system of world economic geography from the perspective of the human community with a shared future. Based on the theory of global integration,the theory of regional differentiation and regional connection,the theory of earth system science and the theory of human-land relationship areal system,this article explores the problems of world economic geography at different scales and hierarchies from the perspective of history,region,nation and non-nation. Finally,on the basis of the new theoretical framework,the article puts forward the key research content of world economic geography from the perspective of the human community with a shared future.

The border port is the gateway of land opening and the hub node of international trade and social-cultural exchanges among the countries. The border ports play an important controlling role for the system of national land development and the integration of international communication networks. Based on the spatiotemporal dimension,this paper described the opening routes and distribution pattern of China's border ports and analyzed their type differentiation and basic features from the perspectives of transport connection,distance between border port and city,and topography. It investigated their spatial concentration using the HH index from various views and revealed the development mechanism of the distribution and spatial concentration of China's border ports. The results showed that China's border ports with modern functions experienced five stages,and concentrated in the northeastern and southwestern of border regions of China,and Xinjiang. Most of border ports are the road ports and are separated from their local cities. The national opening path,geopolitical pattern, natural geographical environment,transport connectivity,hinterland economy have an important impact on the development of the border ports,including location,size and potential. This research can provide scientific guidance for the distribution optimalization and the formation of supporting policies for China's border ports.

The "office address" and "registration address" of the listed company,which are the only two standards for judging the geographical location of the headquarters,are not spatially identical. This phenomenon may lead to inconsistencies between the location or regional attribution of listed companies (headquarters) defined in numerous literature and the reality,thereby questioning the credibility of research data and conclusions. Based on multidisciplinary literature,this article expounds the divergence of enterprise location and its impact on empirical research,verifies the ability of office address and registration address to represent the location of A-share listed companies (headquarters),and discusses the criteria of enterprise location under different circumstances and its impact on location theory. The results show that: 1) The separation of the office address and the registration address will inevitably lead to the discrepancy between the location and the region of the listed company (headquarters) defined in some literatures and the reality,and cause errors in enterprise indicators,regional indicator statistics and enterprise distance,which makes the credibility of the research conclusion doubtful. 2) Among the 117 A-share listed companies with cross-province separation of office address and registration address,up to 85.48% of the company headquarters and office address are the same,the office address is much better than the registration address in representing the location of the company (headquarters),so the relevant research of listed companies should take the office address as the location of the company (headquarters),and the existing literature using registration address should be re-examined. 3) In fact,the separation between business premises and registration address is quite common. The location of the company (headquarters) in economic geography is be a business premises that undertakes economic functions and occupies a certain geographical space,and the registration address should only be applied in a few non-economic research and data statistics. It should pay more attention to the separation of registration address and business premises,which will be beneficial to the development and innovation of location theory in the aspects of location subject,location phenomenon, location factor and location influence.

In the face of the post-epidemic era,the complex environment of anti-globalization and the new requirements of the "dual circulation" national development strategy,it is more urgent to eliminate barriers to the flow and allocation of elements and promote regional economic integration. However,how to observe and measure the spatial effect of institutional barriers is a difficult problem in practice,and there is no corresponding effective theoretical support. The institutional turn of economic geography has brought about the change of research focus from "object and structure" to "institution". This paper introduces the concept of "institutional distance" in the new institutional economics into the study of regional spatial economy,and holds that the "institutional distance" caused by the institutional environment and institutional arrangement differences between local governments provides a new theoretical perspective and measurement for regional spatial economic analysis method. This paper reveals the mechanism of institutional distance in regional spatial development,initially constructs the spatial economic analysis and interpretation framework affecting regional economic integration,establishes a two-dimensional analysis quadrant based on institutional distance and spatial distance,and analyzes three typical types of regional spatial effects.

This paper selects Yuanjia Village,Shangwang Village and Fuchazhen scenic area in Guanzhong area of Shaanxi Province as empirical research areas,constructs a structural relationship model which involves three potential variables of tourism development,rural reconstruction and rural revitalization. Based on questionnaire and using SPSS software,Amos software,this paper probes into the influence effect and mechanism of rural tourism development on rural revitalization. Research shows that: 1) Tourism development has a very significant positive impact on rural tourism reconstruction (0.868),also has a direct positive impact on rural revitalization (0.049),the indirect effect of tourism development on rural revitalization is 0.748. 2) In the two-dimensional effect,tourism development mainly affects the rural reconstruction's economic reconstruction and social reconstruction,followed by spatial reconstruction; tourism development mainly affects rural revitalization's industrial revitalization,talent revitalization and cultural revitalization,compared with ecological revitalization and organizational revitalization. 3) Rural reconstruction has a very significant positive impact on rural revitalization in rural tourism destinations,which is also the most important direct factor to promote rural revitalization,and has full mediation effect between tourism development and rural revitalization. 4) The action mechanism of rural tourism development on rural revitalization is consistent with the DPSIR model. Driven by the rural reconstruction,the tourism development,the market mechanism and the stakeholder,tourism development promotes the comprehensive and in-depth reconstruction of rural tourism destinations,and ultimately realizes rural revitalization in the transformation development process of the optimization or strengthening of rural regional functions.

The rapid development of the digital economy has great potential for promoting urban-rural integration. In order to explore the development and evolution pattern of the digital economy and its impact on urban-rural integration. This paper measures the level of digital economy development and urban-rural integration in Chinese provinces from 2013 to 2020 based on the entropy weight method,and explores the spatial evolution characteristics of the digital economy using the Gini coefficient,Theil index,logarithmic deviation mean,spatial autocorrelation analysis and cold-hot spot analysis. It uses the spatial econometric model to analyze the effect of the digital economy on the level of urban-rural integration. The main conclusions are as follows: 1) The digital economy development shows the obvious differentiation characteristics,but the trend of differentiation development is gradually slowing down. 2) The development level of the digital economy in provincial areas shows a decreasing trend in the gradient of "East-West-Central",with significant spatial clustering characteristics and a gradually increasing trend of overall clustering. 3) The digital economy development has significantly contributed to the improvement of local urban-rural integration. In terms of sub-dimensions,the positive impact of the digital economy on urban-rural integration is dominated by the local effects of digital industrialisation,industrial digitization and digital innovation.

The study of the spatial correlation network of land use carbon emission is of great significance for regional land use collaborative emission reduction. Based on the data of three national land survey,this study calculates the interprovincial land use carbon emissions,and discusses the spatial correlation network structure and evolution process of land use carbon emissions by the methods of social network analysis. It uses the QAP regression analysis to dynamically analyze the driving factors of the spatial correlation network of land use carbon emissions. It's found that: 1) The spatial association of land use carbon emissions had the characteristics of a spatial network,the spatial correlation and stability of the spatial association network of land use carbon emissions were enhanced as a whole,and the internal hierarchical structure as a whole showed a loose trend. 2) The eastern coastal provinces and cities were in the core position for a long time in the spatial correlation network,and the northwest and northeast regions were in a marginal position for a long time. With the development of economy,the role of the central and western regions in the spatial correlation network had gradually strengthened. 3) The plates in the central and western regions and the northeastern region were the main spillover parties of the elements in the spatial association network,and the plates in the eastern and southeast coastal areas were the main beneficiaries of the elements. 4) The geographical spatial proximity,the level of economic development, the environmental regulation,the level of innovation,the energy consumption structure,the proportion of woodland, and the industrial structure have a significant impact on the formation of the spatial correlation network of land use carbon emissions. It is suggested that attention should be paid to the spatial correlation network of land use carbon emission and its characteristics when designing land use emission reduction policies.

Based on the panel data of 260 cities at prefecture level and above in China from 2005 to 2019,this paper examines the impact and mechanism of digital economy on urban economic resilience from both theoretical and empirical perspectives. It is found that: 1) The development of digital economy has significantly improved the resilience of urban economy,and this conclusion still holds after a series of robustness tests. 2) The mechanism test shows that stimulating entrepreneurial activity and innovation activity is the way of digital economy to promote the urban economic resilience. 3) The spatial spillover effect test shows that the development of digital economy has a positive impact on the economic resilience of surrounding cities. 4) According to the heterogeneity analysis,compared with central and western cities and peripheral cities,the digital economy development in eastern cities and central cities has a stronger promoting effect on the urban economic resilience. This study has important policy implications: strengthening the development of digital economy,promoting the deep integration of digital economy and real economy,and giving full play to the role of digital economy in promoting "mass entrepreneurship and innovation",which is an important way to enhance the resilience of China's urban economy.

Based on the analysis of relevant literatures on high-quality development and green logistics,this article constructs the evaluation index system of green logistics level under the high-quality development,uses the TOPSIS-cloud PDR multi-criteria decision-making method to empirically study the development level of China 's provincial green logistics from 2011 to 2020,and identifies the key obstacle factors. The results show that: 1) There are significant differences in the level of green logistics among provinces,but the development trend is positive in the dimensions of function,structure and operation. In terms of time,it shows a trend of decreasing first and then fluctuating upward. The inflection point appears after the concept of high-quality development is put forward. The development stability is strong in coastal areas,it shows the characteristics of radiation and uneven spatial development pattern which is higher in the east than that in the west. 2) The obstacle factors of green logistics development are relatively stable during the research period. The obstacle degree from large to small is the operation dimension,the structure dimension and the function dimension. The top five secondary indicators are the ratio of science and technology investment to GDP,the turnover of goods,the ratio of total import and export of goods to GDP,per capita GDP and fixed asset investment in logistics industry. According to the research conclusions,this paper puts forward suggestions for improving the level of provincial green logistics under the high-quality development from the aspects of ' operation-structure' coordinated development,strengthening regional economic linkage and formulating characteristic development plans.

Based on the panel data of 101 municipal-level cities in China from 2014 to 2021, this paper depicts the evolution pattern of regional gap of urban and rural residents' pensions in China by using the methods of the Dagum Gini coefficient, the Kernel density estimation and the Shapley value, decomposes and analyzes its sources. It's found that: 1) The regional gap of urban and rural residents' pensions in China shows a wave-like upward trend in general. First-tier and new first-tier cities show an inverted U-shaped evolution. Second-tier cities show a decreasing trend. Third-tier, fourth-tier and fifth-tier cities show an increasing trend. 2) There is a large gap urban and rural residents' pensions in China among different classes of cities, and the larger the span of urban classes, the more obvious the gap between the two. 3) According to kernel density estimation, urban and rural residents' pension benefits in China are improving, but the overall regional gap is still widening. The urban and rural residents' pension gap in third-tier cities expands the fastest, the urban and rural residents' pensions show a bipolar or multi-level differentiation in second-tier, fourth-tier and fifth-tier cities. 4) The Dagum Gini coefficient decomposition shows that the regional pension gap of urban and rural residents in China is more derived from different grades of cities. 5) The decomposition of Shapley values shows that economic development level and population mobility are the main reasons for the widening regional gap of urban and rural residents' pensions.

Regional development gap is an eternal research theme in economic geography. In the new stage of China's development, understanding the new trends and causes of regional development gap is the scientific basis for formulating targeted policies to promote coordinated regional development. It's found that the economic gap between coastal and inland regions has slowed down over the past decade, people's living standard gap has shown an expansion trend. The gap has comprehensive widened between regions of the same type in the north and south, such as between urban agglomerations and developing regions. The urban-rural gap has generally alleviated, but the circumstances are still larger in economic backward region. Border provinces' development in China has generally been ahead of neighboring countries. According to the reasons for the new trend of regional development gap, it puts forward policy suggestions for promoting coordinated development of region in the new era, which includes: in the near future, narrowing regional economic gap is as important as narrowing residents' living standard gap. Adapting to the expansion rule of north-south gap and stimulating the momentum of development in the south are conducive to basically achieve modernization in 2035. According to the deployment of fighting a protracted war, after eliminating absolute poverty, supporting the economic development in relatively poor areas should be taken as a key point of regional policy. Facing new challenges and adapting to new situations, it takes solving the new infrastructure as the main point, reverses the continuous expansion situation of regional innovation capabilities between economically developed and underdeveloped regions, and stimulates the contribution of innovation to the balanced development of regional economic.

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.

Taking 1 204 Chinese traditional villages and 843 national intangible cultural heritages in the Yellow River Basin as the research object,this paper attempts to reveal the spatial relationship and genetic mechanism between traditional villages and intangible cultural heritages by using the methods of kernel density,the gravity center model,grey correlation model,and landscape spatial correlation index in order to provide a scientific basis for their holistic protection and synergistic utilization. The results show that: 1) Both traditional villages and intangible cultural heritage in the Yellow River Basin have obvious spatial clustering and heterogeneity characteristics in distribution and show similar spatial distribution patterns. 2) At the macro and meso levels, there is a close spatial relationship between traditional villages and intangible cultural heritage in the Yellow River Basin,but at the micro-level,they only show a low level of positive spatial association. 3) The complex spatial relationship between traditional villages and intangible cultural heritage in the Yellow River Basin is the result of a combination of factors. The internal interaction between traditional villages and intangible cultural heritage,as well as the natural geographical environment,social and cultural environment,and policy environment have an important impact on it.

The report of the 20th CPC National Congress firstly proposed the strategic task to achieve modernization through a Chinese path, which entails the solid support of urbanization and integrated urban-rural development. The combination of urbanization and integrated urban-rural development plays an irreplaceable and important role in achieving modernization through a Chinese path. Chinese-style modernization construction implies a series of basic requirements for urbanization and integrated urban-rural development in the new era, and in response to these requirements, the following specific construction paths are proposed: continuing to unswervingly implement the new urbanization strategy and building a strategic support chain for the high-quality development of urbanization relying on the innovation; promoting high-quality clustering of urban agglomerations in an orderly manner, and making urban agglomerations the core and pioneer areas through a Chinese path to modernization; advancing the high-quality development of the county comprehensively and building the county and small towns into an important carrier area of Chinese-style modernization; boosting the high-quality urban-rural integration and making the integrated urban-rural development as the direction of Chinese-style modernization; constructing beautiful cities and beautiful villages by relying on the shift in driving forces for development. To achieve Chinese-style modernization based on the new-type urbanization and the integrated urban-rural development requires full consideration of regional and urban-rural differences, a comprehensive regional plan for Chinese-style modernization, and a roadmap and timetable for Chinese-style modernization according to local conditions. If the dialectical relationship and path dependence between Chinese-style urbanization and Chinese-style modernization construction are correctly handled, the process of Chinese-style modernization will be gradually accelerated amidst both opportunities and challenges.

This paper used the complex network method to analyze the evolution and community structure of the international soybean trade-weighted network from 2001 to 2019. The results showed that: 1) The global soybean trade network showed the characteristics of expansion at first and then contraction. The overall connection was weak,it showed the trend of collectivization after 2016. 2) In the network,the core export countries are Brazil and the United States,the core import countries are China and the western European countries,and the core "intermediary" countries are Canada and the western European countries. 3) There are mainly three stable communities in the global soybean trade network. The distribution of communities has obvious geographical characteristics. The exporting countries within the communities are more dominant. The "intermediary" countries have a significant impact on the size of the community. China and the United States have different characteristics of status change in the community. It is suggested to increase the self-sufficiency rate of soybeans in China,diversify the source of soybean imports,expand the scope of the community,firmly grasp the acquisition and pricing rights,and then build an international supply pattern centered on China.

Promoting the green transformation of resource-based cities is an important issue to improve the coordinated development of regions and make up for the shortcomings of transformation. Based on the samples of 111 resource-based cities,this paper reveals the power source and driving factors of green transformation of resource-based cities in China from 2004 to 2019 using the methods of the data envelopment analysis and the quantile regression model. The results show that: 1) The green transformation performance of resource-based cities increased cumulatively by 0.33% in 2004-2019. In terms of distribution location,the green transformation performance of resource-based cities in the south of China is higher than that in the north of China. With regards to development types,the green transformation performance of declining-type cities is higher than that of regenerative-type, mature-type,and growing-type cities. 2) From the perspective of endogenous,technological progress has emerged as a catalyst for promoting growth in the performance of green transformation among resource-based cities,with environmental pollution treatment technology improvements making significant contributions. 3) From the perspective of exogenous,there are notable variations in both size and direction regarding how environmental regulation and industrial structure impact the performance of green transformation across different regions and types of resource-based cities. Notably,employment structure optimization and financial development exert substantial positive effects on the green transformation performance of resource-based cities at each quantile level.
