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 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.

As a new carrier to promote the integrated development of rural industries,leisure agriculture and rural tourism are the "green" driving force to increase farmers' income and get rich. With the help of the "quasi-natural experiment" of the national leisure agriculture and rural tourism demonstration county policy,this paper empirically tests the impact,mechanism and constraints of the development of leisure agriculture and rural tourism on farmers' income based on the panel data of 816 counties in China from 2005 to 2018 and the multi-period PSM-DID method. The study finds that the policy of leisure agriculture and rural tourism demonstration county will increase the per capita net income of local rural residents by 3.04%,especially in areas with better rural tourism resource endowment and higher economic development level,the income-increasing effect of the policy can be brought into play to a greater extent. Moreover,with the passage of time,the income-increasing effect of the policy is becoming stronger and stronger. In addition,the mechanism test shows that improving the level of rural non-agricultural employment and increasing the adoption of agricultural technology are important intermediary mechanisms for the policy of demonstration counties to increase farmers' income. The findings of this paper not only provide an important practical basis for vigorously developing leisure agriculture and rural tourism,but also provide useful policy enlightenment for promoting rural revitalization and realizing common prosperity.

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.

Taking the villages and households in Jia County on the Loess Plateau as research object,based on the theoretical framework of rural construction theory and livelihood resilience,this paper quantitatively describes the impact of changes in rural construction level on the household livelihood resilience of 61 village-level units in 1990-2020. It uses geographically weighted regression model to identify and analyze the key rural construction factors and their spatial effects. The results show that: 1) Since 1990,rural construction level has been upgraded from a low level to a high level,and livelihood resilience has been increased from a weak level to a medium level. Spatial pattern in the county was basically the same,with the characteristics of "high in the east and low in the west,and high in the south and low in the north". 2) There is a strong correlation between household livelihood resilience and rural construction level. Among the factors of rural construction,road traffic conditions,grassroots governance capacity,market construction and compulsory education have significant positive effects on livelihood resilience. 3) The strong effect area of each element has obvious spatial differentiation characteristics. According to the local conditions,rural infrastructure,public services and grass-roots governance should be upgraded to achieve comprehensive rural revitalization and sustainable livelihoods.

The concept of "landscape gene cell" originally refers to the basic unit of traditional urban landscape,which is the analogy of organic somatic cells. All settlement buildings and structures can actually be regarded as cell units with different forms and functions,which jointly constitutes the organic whole of settlement cultural landscape. This study continues this concept and the analogy with the biological characteristics of biological cells. The study suggests that landscape gene cells have the following biological characteristics: metabolic activities; proliferation and apoptosis; inheritance and mutation. Among them,metabolic activities include spatial metabolism,material metabolism,and functional metabolism,and genetic patterns include cell diffusion,cell mutation,and cell constancy. Finally,three traditional settlements in northeast and southeast Hunan--Zhangguying Village,Zhongtian Village and Shanggantang Village are selected to explain the expression of the biological characteristics of landscape gene cells.

It's very important to ensure a stable soybean supply for national food security. Optimizing the layout of China's soybean import with the goal of minimizing risk and cost is the practical need to ensure the security of soybean supply chain. Based on the soybean trade data from 2000 to 2020 and the risk-cost planning model,this paper analyzes the optimal layout strategy of China's imported soybeans,investigates the feasibility of expanding the market to potential exporting countries,and simulates the adjustment direction of import layout under the change of international economic and trade pattern. The results show that: 1) China's soybean import pays more attention to controlling economic costs,relatively ignores avoiding market risks,there is a certain optimization space. 2) Since 2017,the soybean import volume has exceeded the safe and economic scope. It is necessary to appropriately control the growth of soybean import scale on the basis of ensuring domestic demand. 3) From the perspective of the optimal import volume of various countries Brazil and the United States both play an important role in China's soybean import,which indicates that it should develop more soybean production capacity of importing countries such as Argentina,Canada and Russia,and potential source countries such as Paraguay and Bolivia. 4) The national risk of the United States increases,the export volume of Brazil decreases and the domestic demand increases,which all increase the cost and risk of China's soybean import. Therefore,it needs effectively expand domestic soybean and oil crops production,stabilize soybean imports from Brazil and the United States in the short term,release the expectation of stable economic and trade cooperation in the medium and long term,and deeply tap the potential of global soybean export. In the future,it is necessary to integrate and construct the risk assessment and warning system of soybean global supply chain,strengthen the simulation and prediction of soybean economic and trade cooperation,and ensure the security of the soybean supply chain system.

Since the Reform and Opening up,China has continuously promoted the development of opening up,and has preliminary established a comprehensive pattern of opening up. The Belt and Road Initiative (BRI), which is put forward in 2013,is not only the internal demand for China to create a new pattern of all-round opening up, but also an important support for building China into a modern socialist country. In the new era, the road of Chinese modernization proposed in the Report of the 20th CPC National Congress provides new guidance for high-level opening up and high-quality development of the BRI. Under this background, on the basis of reviewing the progress of China's opening up and the BRI, the article explains the new requirements and missions of high-level opening up and the Belt and Road construction,and puts forward some policy suggestions to promote the high-quality development of Belt and Road construction. The study suggests that high-quality development of BRI should focus more on deepening the 'five focuses' cooperation,expanding new cooperation areas, optimizing regional pattern of opening up, and strengthening enterprise risk prevention. Moreover, it suggests that geographers should systematically study the theory of Chinese path to modernization, and carry out research on international development,national geography,world geography, Belt and Road construction cases, geopolitics, geo-economy, geo-environment, etc.

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.

Based on the panel data of 13 cities in the Beijing-Tianjin-Hebei region from 2011 to 2019,this paper calculates the development level of the digital economy in the Beijing-Tianjin-Hebei region using the time-series global principal analysis method,and explores the spatial characteristics of the digital economy in the Beijing-Tianjin-Hebei region using the exploratory spatial data analysis,analyzes the spatial effect of the digital economy using the spatial econometric model,and identifies the key factors affecting the digital economy of Beijing-Tianjin-Hebei region. The results show that: From the perspective of spatial evolution pattern,the digital economy shows the seriously unbalanced development in the Beijing-Tianjin-Hebei region and the characteristics of an obvious hierarchical structure. From the perspective of spatial correlation,it shows "H-H" type spatial agglomeration characteristics in Beijing,Tianjin and Langfang,and show "L-L" type spatial agglomeration characteristics in Handan,Xingtai and Hengshui. From the perspective of spatial effect,technological progress and industrial structure have a significant direct effect on the development of digital economy,while per capita GDP,the number of urban employment and industrial structure have a significant positive spatial spillover effect,and education level and technological progress have a significant negative spatial spillover effect. From the heterogeneity test,the impact of urban scale heterogeneity is very obvious. Accordingly,the paper puts forward some policy suggestions for promoting the integrated development of the digital economy in Beijing,Tianjin and Hebei.

The paper starts with the differentiated protection of traditional villages at a macro scale,and selects four traditional villages with local characteristics as research objects which belong to Zhejiang,Anhui,Shaanxi and Yunnan respectively. Using geographic model and GIS spatial analysis methods,this paper comprehensively analyzes spatial distribution pattern characteristics of traditional villages in different regions and its influencing factors from city and county perspectives. The results show that: 1) The traditional villages in four provinces show a aggregation distribution. The traditional villages in Anhui province present the most uneven distribution and the highest concentration, followed by Zhejiang and Shaanxi, it has the lowest concentration in Yunnan Province. 2) The traditional villages in four provinces mainly locate in hilly and mountainous areas. The traditional villages mainly locate in hilly areas of Shaanxi Province and mountainous areas of Zhejiang Province. At the same time,the distribution of traditional villages shows the characteristics of river-oriented and lake-oriented trend. 3) Traditional villages have obvious agglomeration in urban centers,and most villages distribute in central townsare within 30 km. In terms of transportation,traditional villages in Anhui Province has the highest accessibility,while there has the worst in Yunnan Province. 4) In some cities of Shaanxi and Yunnan, there is a positive correlation between the density of traditional villages and economic development. Except of the above, there is a negative correlation between them. It indicates that there are regional differences in the impact of social and economic development on traditional villages. Based on the analysis of the characteristics of traditional villages in different regions,this paper puts forward the differentiated protection and development countermeasures.

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.

This paper uses NPP-VIIRS nighttime lighting data and Gaode's population migration data to study the spatial structure characteristics of the Yangtze River Delta urban agglomeration using standard deviational ellipse method,spatial Moran index,network centrality analysis and core-edge analysis and to investigate the influencing factors of the Yangtze River Delta population migration network structure in terms of economic development level,industrial structure,public services and migration costs. It's found that: 1) The development of the Yangtze River Delta urban agglomeration is uneven,which is higher agglomeration in the east than that in the west. There is a significant positive spatial correlation,specifically in the form of a core-edge spatial structure with larger cities close to larger cities and smaller cities close to smaller cities,the urban agglomeration expands along the Yangtze River,the Beijing-Shanghai high-speed railway and the direction of Nanjing-Hefei. 2) According to the intensity of population migration,the Yangtze River Delta urban agglomeration is divided into four levels of population migration networks,with the network density increasing and the number of node cities increasing as the network level decreases. Among them,Shanghai,Suzhou,Wuxi,Nanjing,and Hangzhou have high degree of density and intense radiation and agglomeration effect. 3) The Yangtze River Delta urban agglomeration has an apparent core-edge structure,with a polycentric,networked,and synergistic development pattern forming within the region. 4) Wage level,industrial structure,transportation accessibility and medical services are the main influencing factors on the network structure of the population migration of the Yangtze River Delta urban agglomeration,all of which significantly promote population migration.

： As an important measure to improve our multi-level medical security system,the integration of resident medical insurance is of great significance to realize the urban and rural integration,promote the fairness of consumption and improve the social welfare. Based on the review of the policy implementation of the resident medical insurance integration in China and the panel data of 278 cities at the prefecture level and above from 2006 to 2019,this paper uses the methods of time-varying DID and spatial DID to explore the effect and mechanism of the resident medical insurance integration on the urban-rural consumption gap. Results show that: 1) The integration of resident medical insurance and the urban-rural consumption gap index show the characteristics of spatiotemporal coupling,which exhibits a gradual diffusion from coastal regions to inland areas and a gradual alleviation from inland areas to coastal regions respectively. The urban-rural consumption gap index is significantly lower in the Pearl River Delta,Yangtze River Delta,Shandong Peninsula which are the earlier policy pilot areas. 2) The integration of resident medical insurance can significantly alleviate the urban-rural consumption gap,and there is a spatial spillover effect,which will slow down the urban-rural consumption gap in cities with similar economic development level,and aggravate the urban-rural consumption gap in geographically adjacent cities. 3) By narrowing the urban-rural income gap and reducing precautionary savings,the integration of resident medical insurance alleviates the urban-rural consumption gap,and its effects on consumption inequality are heterogeneous in different economic agglomeration areas and cities with different levels of economic development.

Rural culture has multiple values such as history,culture,economy and ecology,and need to be protected through utilization and utilized in protection to realize living inheritance. The development of tourism industry is not only an important force for rural revitalization,but also an important path for the living inheritance of rural culture. And the emotional elements contained in rural cultural tourism have a close bond with "Place". Based on the local theory of human geography, this paper analyzes the local brand construction mode of rural culture and its tourism revitalization path,and takes the geomantic omen of Chengkan Village as a case study. The results show that: 1) The local brand construction of rural culture takes cultural authenticity as the core, local knowledge, local dependence and local identity as the multi-wheel drive, activates local attachment and reshapes geographical imagination. 2) Based on this local brand construction,the tourism activation of rural culture makes the authenticity culture rooted in rural areas flow in tourism activities. Taking cultural authenticity as the starting point,it forms a circular path through the nodes of cultural consumption, delocalization, cultural reproduction and relocalization.

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.

The report of the 20th CPC National Congress points out that the most arduous and complex task in the comprehensive construction of a socialist modernized country still lies in the rural areas. The endogenous capabilities play a critical role in solving this problem. Rural households serve as the fundamental organizational units of the rural economy development. The article reviews the research on the geography of rural household,such as the role of rural households in rural development as well as the relationship between rural household economic activities and the geographical environment,and analyzes the development status and related development thoughts of new economic subjects in the process of rural modernization, such as the relationships between rural households and enterprises, farmers' development consciousness and entrepreneurial spirit. It proposes the novel research framework on the geography of rural household in the process of rural modernization. Compared to the existing research on the geography of rural household,this framework adds the location and spatial structure of new agricultural management entities,such as family farms,agricultural cooperative organizations, agricultural social service organizations, and agricultural leading enterprises,and the spatial correlation between agricultural leading enterprises and other agricultural management entities including rural households. Consequently,the autonomous development capabilities of households are further expanded,and entrepreneurial spirit is introduced. The article emphasizes the need for special attention to the entrepreneurial spirit of rural areas in the context of increasing marketization of rural households and coexistence with new agricultural management entities in rural regions. In contrast to general entrepreneurship, it highlights innovations in the background of specific cultural and institutional settings,innovations related to special stages and industries,and innovations arising from the interconnection and flows of urban-rural factors. Meanwhile,the relationship between these economic entities and the geographical environment represents a particular focus for the study of the geography of rural households.

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.

Promoting high-quality development of new urbanization is the only way to realize the Chinese modernization. This paper constructs the evaluation index system of high-quality development of new urbanization from five aspects of economic development,infrastructure,urban-rural coordination,green low-carbon and innovative development,and analyzes the high-quality development level of new urbanization in Guangdong Province from 2009 to 2020 by using the combination weighting method,time-ordered weighted average operator method and spatial statistical analysis method. The results show that: 1) The level of high-quality development of new urbanization in Guangdong Province is not high,and the change trend of five aspects is different. The green and low-carbon has the largest contribution to the high-quality development of new urbanization,and the innovative development has the smallest contribution. 2) It has a high level of comprehensive development and strong capacity for sustainable development in the Pearl River Delta region ,followed by the west and north of Guangdong Province,it is the weakest in the east of Guangdong Province. 3) The urban spatial association pattern is mainly homogeneous agglomeration. High-high spatial agglomeration cities are distributed in the Pearl River Delta,and low-low spatial agglomeration cities are in the rest of Guangdong. 4) Economic foundation,technological innovation ,government guidance,industrial structure and foreign trade are the core influencing factors for the high-quality development of new urbanization in Guangdong Province. Finally,policy suggestions are put forward from three aspects: improving the system and mechanism of regional coordinated development,formulating differentiated development plans and optimizing the implementation path.

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.

In recent years,the birth rate of Chinese population continues to decrease,the demographic dividend period is coming to an end,and the population contraction phenomenon becomes more and more obvious at the county level. Based on the data of 6th National Census and 7th National Census,this paper constructs the measurement index of permanent population and working-age population to investigate the situation of population contraction at the county level,analyzes the spatial pattern of population contraction,and explores the related factors affecting the population contraction by using the spatial Durbin model. The results show that: 1) In 2010-2020,the decrease of permanent population accounted for about 53% at the county level,over 70% of the counties (districts) showed a decrease of working-age population to some extents,and over 96% of the counties (districts) showed a growth rate of working-age population less than that of the permanent population. 2) From the perspective of space,the three provinces of Northeast China and Shanxi are concentrated in the counties where the permanent population is shrinking,while the counties that maintain population growth are mainly concentrated in Zhejiang Province,Tibet Autonomous Region and Xinjiang Uygur Autonomous Region. Some developed eastern regions,such as Tianjin, Beijing, Shanghai and Jiangsu,are also facing shrinking working-age populations. 3) The factors affecting the county population contraction are very complicated. Economic development level,industrial structure,birth rate,geographical position,education level and administrative level all affect the county population contraction significantly.

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.

To analyze the spatial distribution and influencing factors of national-level "Little Giant" enterprises which focus on specialization,refinement,uniqueness and innovation has important reference value for promoting the transformation and upgrading of small and medium-sized enterprises and the innovation-driven development in China. This article investigates the spatial distribution characteristics of 4 922 national-level "little giant" enterprises in China using spatial statistical method and identifies the main influencing factors by the Geodetector. The results reveal that: 1) As a whole,China's national-level "little giant" enterprises show an agglomeration distribution pattern of "dense in the east and south,sparse in the west and north",and tend to spread westward and northward. 2) At the regional scale,there is a "three-pole and multi-core" agglomeration pattern based on "central city and urban agglomeration". China's national-level "little giant" enterprises show the even distribution in the east of China except of that in other regions. The national-level "little giant" enterprises concentrate in urban agglomerations,among which it has big difference. 3) The degree of spatial disequilibrium distribution showed that the order from high to low is high-tech service industry,machinery and equipment manufacturing industry,high-tech manufacturing industry,wholesale and retail industry,food and light textile industry,mining and processing industry,and industrial supporting service industry,it has obvious difference among the different industries. 4) The spatial distribution pattern of national "little giant" enterprises is the result of many factors. Infrastructure and policy environment are the main influencing factors,economic strength and social development are the important influencing factors,natural conditions and innovation ability are the basic influencing factors. There is a significant nonlinear strengthening effect among the influencing factors,but there is a great difference in the interaction of each dimension of the influencing factors.

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.

Improving the business environment is a realistic need to speed up the building of unified domestic market and realize coordinated and high-quality development among regions in the new era. It is also an inherent need to build a modern socialist country in an all-round way. This study constructs the evaluation system of business environment from six dimensions: market environment,government environment,commercial environment,open environment,legal environment and public service. Based on the entropy TOPSIS method,it measures and evaluates the comprehensive level of business environment in China's provinces during the "13th Five-Year Plan" period,and analyzes the regional differentiation of business environment. The results are as follows: 1) The stability and volatility of the comprehensive evaluation of business environment in each province coexist. 2) There are significant provincial and regional differences in the comprehensive level of business environment in each province,it presents the overall gradient evolution characteristics in time and space. 3) There is a large space for optimization between the business environment of each province and the ideal business environment. It puts forward some feasible suggestions for building first-class business environment,which includes establishing a multi-governance evaluation system based on government-market-society,identifying and making up for the sub-environment weakness of provincial-business environment,and focusing on narrowing the gap in the comprehensive level of business environment in the eastern, central and western regions.

The construction of the theoretical system of Chinese path to modernization provides academic guidelines for tourism geography research in the new era. Based on analyzing the scientific connotation of Chinese path to modernization and combining the disciplinary orientation and development trend of tourism geography,this article constructs a new framework for tourism geography research from the aspects of theory,methodology and application. It is emphasized that the disciplinary advantages and regional,comprehensive,intersectional and applied characteristics of tourism geography must be brought into play,with the theory of human-environment relationship in tourism as the core,and the comprehensive application of multidisciplinary theories and technical methods. While strengthening the research on tourism spatial analysis,destination evolution and sustainable tourism development, tourism geography research should pay attention to the innovative application of modernity theory,symbiosis theory, justice theory,theory of scenes,theory of a community of shared future for mankind and new form of human civilization,and gradually build a theoretical system of tourism geography that meets the requirements of Chinese path to modernization. As the efforts in promoting the independent knowledge innovation in tourism geography,it is proposed to strengthen the tourism geography research on "Chinese characteristics",specifically to explore in depth the scientific issues such as the characteristics of population (demand) and the law of mobility,the mechanism and path of tourism development to promote common prosperity,the deep integration and high-quality development of culture and tourism,the harmonious coexistence of human-environment relationship and sustainable development of tourism,the geographical pattern of international tourism,and the role of tourism in promoting world peace. Tourism geographers should be the pioneers and agents in the construction of Chinese path to modernization in tourism research and actively undertake the political mission of responding to national strategies,the social mission of promoting common prosperity,the cultural mission of coordinating "two types of civilization",the ecological mission of promoting the harmony of human-environment relationship,the economic mission of propelling the service industry,and the international mission of advancing peaceful development,fundamentally to better serve the Chinese path to modernization and high-quality development of tourism.

Improving the spatial governance level is an important force for the modernization of national governance capabilities. With the development of smart society,constantly enriching data sources have become powerful weapons for perceiving and understanding urban space. Urban spatial governance,as a key level connecting the preceding and the following in the spatial governance system,currently lacks a unified and coordinated framework to address the issues of invalidation,disorder,and imbalance it faces. This makes data-driven governance become the necessary path for the digital and intelligent transformation of future governance,and thus deeply promotes the logical transformation from the empirical spatial governance to the scientific. Fully tapping into the potential of data resources can help strengthen the connections between urban spatial governance in different spatial units,levels,and entities. The research proposes that data-driven urban spatial governance should start from the massive multi-source geographic information data and urban perception data,creates an interconnected data management platform and an indicator system that emphasizes both rigidity and flexibility. Furthermore,it should establish a clear basic framework for urban spatial development through the construction of urban safety and functional patterns,utilize the urban intelligent brain platform to form an intelligent governance framework for spatial monitoring,evaluation,simulation,and decision-making throughout the entire process,and achieves the ultimate goal of high-quality,coordinated,and fair development of urban space.

The report of the 20th National Congress stressed that comprehensively promoting the great rejuvenation of the Chinese nation through Chinese path to modernization and building a new development pattern is the only way to realize Chinese path to modernization,which is a systemic and deep-seated change bearing on the overall situation. Humanities and economic geography is a practical science,which needs to face the national strategic needs in the new era and reflect on the new requirements,new connotations and important scientific issues in the field of regional development. This paper briefly reviews the statements made in the 20th National Congress report on Chinese path to modernization and the construction of a new development pattern,as well as the relationship with the new pattern of regional development. It studies the multi-dimensional influences on the concept,stages,key points,regional relations,urban-rural relations,spatial governance and opening of regional development. Furthermore,it analyzes the rich spatial connotation of the new development pattern,including the coordinated development of regions,integrated urban-rural development,modernization of spatial governance,and a dual circulation. It then benchmarks the regional coordination level of major countries in the world. Finally,this paper puts forward several important issues of geography in the process of Chinese path to modernization and the construction of new development pattern: the balance and synergy between major regional strategies,special type areas and coordinated regional development;new-type urbanization,rural revitalization and urban-rural integration;rational distribution of population,economy and society;major function-oriented zones,sustainable development and territory spatial system;the Belt and Road,dual circulation and opening up;and the new pattern,new factors and new mechanisms of regional development in China.

This study constructs a data set of campsites in China,quantitatively analyzes the spatial distribution pattern,equilibrium situation and spatial density of campsites in China,and explores the influencing factors and driving mechanism of the spatial distribution of campsites in China by combining the entropy method and the Geo-detector model. The results show that: 1) Campsites show a clustered spatial distribution pattern as a whole,and the spatial distribution of campsites presents the concentrated and unbalanced characteristics. 2) The distribution density of the campsites has obvious layering characteristics. In terms of the spatial distribution,it presents a concentrated distribution structure based on 'four cores-banded area-dotted group'. 3) The spatial distribution of campsites is the result of the comprehensive effect of natural ecological environment,traffic location,tourism and leisure level,socio-demographic condition and the level of economic development,and the influence ability of each influencing factors on the spatial distribution of campsites has dynamic differences. 4) Traffic location has synergistic effect and security effect on the spatial distribution of campsites,resource endowment has guiding effect and leverage effect on the spatial distribution of campsites,and social population and economic level have reshaping effect and superposition effect on the spatial distribution of campsites,and COVID-19 epidemic plays the role of catalyst effect. There is a strong symbiotic relationship between 'road-scenery-city-human-land' in the spatial distribution of campsites across the country. Driven by multiple factors, campsites show the distribution law of 'along the line, near the scenery and near the city'.

The spatial reconfiguration and optimization of settlements contributes to the transformational development and organic spatial renewal of villages,and is an important way to promote the inheritance of traditional villages and realize rural revitalization. Taking Chongmudang Village,a traditional tourism-oriented village,as a case study,the study is guided by the theory of system theory and uses the methods of landscape genetic analysis,remote sensing interpretation and GIS spatial analysis to accurately identify the evolutionary characteristics of the spatial reconfiguration of the internal and external systems of the settlement and deeply explore the mechanism of spatial reconfiguration and rural revitalization. The study shows that: 1) Landscape genetics and residential architecture are the main components of the spatial reconstruction of Chongmudang settlement,with landscape genetics showing a harmonious character of slight changes but blending into the local area,the harmonious coexistence of old and new landscapes,and the dynamic continuation of traditional styles. Residential architecture shows a clear characteristic of settlement form at the overall level, the evolution of building functions from single to composite, and the orderly spatial expansion at the local level. 2) The external system of Chongmudang Village guides and constrains the settlements,showing the characteristics of proximity, centrality and hydrophilicity, the closer the settlements are to the roads, infrastructure and water, the denser they are. 3) With the external environment driving and the internal elements responding,Chongmudang Village adopts a three-dimensional reconstruction path of cultural continuity,spatial order and material renewal to promote the spatial reshaping of spatial elements,spatial pattern optimization and spatial organization of village settlements, which provides a cultural,spatial and material basis for rural revitalization, and empowers the practice of rural revitalization.

The digital new economy led by live-streaming e-commerce has become an important driving force for urban development. It is of great theoretical and practical significance to study the spatial location characteristics and the influencing factors of live-streaming e-commerce enterprises at the urban scale. Taking Hangzhou as a case,this study analyzes the location characteristics of the live-streaming e-commerce enterprises in Hangzhou in 2016,2019 and 2021 based on the data of Tianyancha,establishes the "subject-market-space" analysis framework from the perspective of "people,goods and market" in the field of e-commerce,and reveals the influencing mechanism of location choice of Hangzhou live-streaming e-commerce enterprises using multi-scale geographically weighted regression (MGWR) model. The results show that: 1) The live-streaming e-commerce industry is rapidly reshaping the spatial pattern of the digital industry in the main urban area of Hangzhou. Since 2016,it has accelerated outward expansion and formed the live-streaming economic plates which are Yuhang,Binjiang-Xiaoshan and Linping-Qiantang,showing a special spatial evolution trend of "low in the center and high in the periphery". 2) The three major clusters have formed a pattern of professionalization and specialization. The core competitiveness of Yuhang cluster lies in high-quality life service facilities and good environment for companies' innovation. Linping-Qiantang cluster with professional market and diversified talent supply,coupled with relatively low housing prices,attracts a large number of live bases for small retails or wholesale industry. Binjiang-Xiaoshan cluster has multiple advantages and is comprehensively the strongest one. 3) In comparison with the classical location theory,industrial basis, employment cost and transportation accessibility are still the key factors affecting the location choice of live-streaming e-commerce enterprises. However,new location factors such as human demand,enterprise incubation and talent supply play an important supporting role in the development of live-streaming e-commerce industry,and there is spatial heterogeneity for all factors.

Digital technology innovation is the core driving force of the digital economy development. An in-depth study on the regional distribution pattern and its formation mechanism of digital technology innovation is helpful to promote the regional digital economy and its high-quality development. Based on the corresponding relationship between digital economy and international patent classification,this paper obtains the patent output data of digital economy from 2003 to 2018,and analyzes the spatial and temporal pattern of digital technology innovation and its factors in the Yangtze River Delta. The results show that: 1) The scale and vitality of digital technology innovation show obvious spatial differentiation,and form a pattern of agglomeration distribution in Shanghai,southern Jiangsu,northeastern Zhejiang and central Anhui,and the agglomeration degree is decreasing. 2) The results of Moran' I and spatial measurement show that the scale and vitality of digital technology innovation in the Yangtze River Delta region have a significant spatial spillover effect. 3) The results confirm that economic development,human capital,capital enrichment,digital access and infrastructure construction have a significant positive impact on digital technology innovation,while environmental pollution has a significant negative impact. The transformation of the technological and economic paradigm of technological innovation provides a new opportunity for the economic development of the relatively backward areas to catch up. In the future,the high-quality development of central and western regions should pay more attention to the cultivation of the core competitiveness of digital economy,and strengthen the construction of digital infrastructure and the construction of digital technology innovation ability.

The Report to the 20th National Congress of the Communist Party of China proposed promoting national rejuvenation through the Chinese path to modernization,and elaborated the scientific connotation,essential requirement,grand blueprint,and realization route of the Chinese path to modernization.

Intelligent logistics is an important support for the modern supply chains and plays a key role in China's deep involvement in the global industrial and value chain division of labor and cooperation. This study takes 30 provincial units in China from 2006 to 2020 as the research objects, and explores the network structure and influencing factors of the spatial connection in the intelligence of the logistics industry by using a range of methods,including the entropy weight and the coefficient of variation integrated assignment method,the modified gravity model,the social network analysis method and the geographical detector. The results show that: 1) The spatial connection intensity in the intelligence of the logistics industry has increased over time,yet the overall connection effect remains insufficient. In terms of spatial distribution,the spatial connection intensity in the intelligence of the logistics industry which displays a characteristic of "club convergence" shows a significant layer decreasing trend in the eastern,central and western regions. 2) The network structure of the spatial connection intensity in the intelligence of the logistics industry changes from the simple and sparse characteristic to the complex characteristic over time,and the spatial pattern is characterized by "density in the east and sparsity in the west". In addition,the network efficiency of the spatial connection intensity in the intelligence of logistics industry is declining,and the inter-regional connection is at the stage of uncoordinated development. 3) The research reveals that there is heterogeneity in the influence of different driving factors on the spatial connection intensity in the intelligence of logistics industry. And the influence ability of the driving factors are,in descending order,innovation ability,economic development,education level,openness to the outside world,industrial structure,government regulation and control,transportation infrastructure and asset investment. Moreover,the influence of the interaction factors after the combination achieves a two-factor growth.

Ecological well-being performance (EWP) reflects the sustainability of regional development. Clarifying the economic and environmental effects of EWP change is of great significance for the coordinated promotion of economic development,environment protection,and people's well-being. The EWP of urban agglomeration in the middle reaches of the Yangtze River was measured from 2005 to 2020. A panel regression model was used to analyze the economic and environmental effects of EWP and the stage characteristics of the effects,under the carbon peaking and carbon neutrality goals. The study shows that: 1) During the study period,the improvement of EWP in the study area had an economic inhibitory effect and a significant carbon emission reduction effect. 2) The economic effect of EWP in the study area showed a stage-specific characteristic. The coordination between EWP and economic growth gradually increased. EWP mainly exhibited economic disincentive effect in 2005-2012,economic promotion effect started to appear in 2013-2020. 3) The environmental effects of EWP in the study area showed phased characteristics,and the carbon emission reduction effect showed a strengthening trend. The increasing effect of EWP on per capita carbon emissions changed to the reducing effect,and the reducing effect of EWP on carbon emission intensity was further enhanced.

The construction of urban green infrastructure plays a significant role in improving urban thermal environment and green high-quality development. 270 literatures related to thermal comfort analysis of urban green spaces retrieved from the Web of Science core database in 2000-2020 are used to sort out the research progress and trends with CiteSpace software. The results show that: 1) The research on thermal comfort of green infrastructure can be divided into three stages. The differences in disciplinary attributes have led to multiple independent core teams at home and abroad,and the research shows the characteristic of strong geography. 2) The research highlights closely follow the changes in international facts,presenting thematic diversity,multidisciplinary participation,and multi-scale effects. The focus of the research has gradually shifted from the impact of urban climate change on environmental thermal comfort to exploring the impact of environmental thermal comfort on the high-quality lifestyle of residents. The research shows the characteristics of rapid growth and phased changes. 3) Currently ,the research value demands are gradually shifting to the residents,and the research on the improvement of thermal comfort of diversified green infrastructure by using the intersection of technology and disciplines will become the focus.

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.

As China's economy enters the high-quality development stage,the industrial structure will also be deeply adjusted,which will have a significant impact on the air quality. Based on panel data of 285 cities at prefecture level and above in China from 2001 to 2020,this paper explores the temporal and spatial evolution of PM_2.5,empirically analyzes the impact of industrial structure adjustment on PM_2.5 using spatial Durbin model,and tests the regulatory role and specific mechanism of industrial agglomeration. The results show that: 1) The overall PM_2.5 of Chinese cities presents an inverted U-shaped characteristic,which is rising first and then falling. Cities in Beijing-Tianjin-Hebei,Central Plains,Shandong Peninsula and other regions are always high value regions. 2) China's urban PM_2.5 has obvious spatial correlation,showing the characteristics of "expansion before contraction". 3) The increase in the proportion of the secondary industry has a significant positive correlation with urban PM_2.5,while the proportion of the tertiary industry has a significant negative correlation with urban PM_2.5. 4) Whether it is manufacturing industry agglomeration or producer service industry agglomeration,it plays a positive role in adjusting the industrial structure to affect urban PM_2.5 and the latter has a greater positive role. 5) Industrial structure adjustment can reduce urban PM_2.5 concentration by reducing pollutant emissions.

Digital technologies such as mobile Internet have empowered the traditional retail industry and promoted the interactive integration of online and offline retail space. The new retail model of community group buying with presale system has developed rapidly, and gradually changed the shopping way of residents. The research on community group buying is mainly focused on the concept connotation, operation mode, distribution mode and distribution center location. The discussion of spatial distribution pattern of the pickup points still needs to be further deepened. Based on the data of the seventh national population census, road density and POI (Point of Interest), this paper analyzes the spatial distribution pattern of pickup points of community group buying in Guangzhou by the means of standard deviation ellipse, kernel density analysis and multiscale geographically weighted regression, and explores its influencing factors. The results show that: 1) The pickup points of community group buying in Guangzhou exhibit the "center-periphery" distribution pattern, its distribution density shows decreasing trend from the city center, suburbs to outer suburbs. It shows the continuous agglomeration in the central area and cluster distribution in the outer suburbs, which reveals that the spatial distribution pattern of the self-picking points of community group buying has a high matching degree with the population density. 2) Convenience store density, population density, supermarket density, comprehensive market density and the proportion of young and middle-aged residents have a significant positive impact on the spatial distribution of pickup points of community group buying, while express network density has a significant negative impact. The spatial distribution preference of pickup points of community group buying is in areas with dense traditional retail distribution, such as convenience stores, supermarkets, comprehensive markets, indicating that the pickup points community group buying are path-dependent on the distribution of traditional retail space.
