Under the background of"Digital Commerce for Rural Vitalization",rural E-commerce has experienced rapid development.However,agricultural products like strawberries,often produced by small-scale,fragmented,and less competitive individual farmers,struggle to meet the compliance and scalability demands of E-commerce,thereby constraining high-quality local economic development.Aiming to address this issue,this paper,guided by relevant policies and strategies,employs case analysis and logical deduction to explore the industrialization path of the"Cooperative+E-commerce"model for the strawberry industry.The research finds that by optimizing the cooperative's organizational structure,implementing multi-channel E-commerce strategies,upgrading the supply chain(including cold chain and quality traceability),and engaging in collaborative brand building,a robust industrial system can be formed.Supplemented by benefit evaluation,policy support,and regulatory oversight,this system can effectively bridge small-scale production with the broader market.This study concludes that this pathway can enhance the added value of the strawberry industry,increase farmer incomes,and provide practical insights for promoting high-quality local economic development. 展开更多

This study investigates the coordination between regional economic growth and ecological sustainability within the context of high-quality town economy development.To address the challenges of balancing economic expansion with environmental protection,a comprehensive evaluation index system is constructed,encompassing two key dimensions:regional economy and ecological environment.Using panel data from 2013 to 2022,the coupling coordination degree model is employed to quantify the interactions and synergy between these dimensions.Additionally,spatial econometric methods are applied to calculate both global and local Moran’s Index,revealing spatial clustering patterns,regional disparities,and heterogeneity.The relative development model further identifies critical factors influencing regional coordination,with a focus on the lagging development of basic infrastructure and public services.The findings demonstrate a positive temporal trend toward improved regional coordination and reduced development gaps,with a spatial pattern characterized by higher coupling degrees in eastern and central regions compared to western areas.Based on these results,this study proposes actionable strategies to enhance coordinated development,emphasizing ecological conservation,the establishment of green production and consumption systems,ecological restoration,and strengthened municipal collaboration.This revised abstract emphasizes the study’s purpose,methods,and key findings more clearly while maintaining a professional and concise tone.Finally,based on the above analysis results,the corresponding coordinated development suggestions of regional economy and ecological environment are given from the aspects of ecological environment protection measures,green production and consumption system construction,ecological environment restoration and municipal coordination. 展开更多

Integrated urban-rural development is an inevitable choice for promoting Chinese modernization.High-quality integrated urban-rural development is essentially a practical response to the current multi-factor and multi-sectoral challenges in urban-rural relations,and plays an important role in implementing the new development philosophy,which promotes Chinese modernization.The theoretical logic supporting the function it plays in enabling Chinese modernization lies in the following aspects:it leverages the free flow of population and resources between urban and rural areas and thus facilitates the balanced development of China’s modernization;it advances the common prosperity of all people through its new type of urban-rural and industrial-agricultural relations;it fosters the coordinated development of the material and spiritual civilizations through the integration of urban and rural cultures;it promotes steering the modernization toward green development through the joint building and managing of the overall urban-rural ecosystem;and it drives modernization in a harmonious and stable direction through integrated urban-rural development.Currently,integrated urban-rural development still faces challenges such as restrictions on the two-way flow of factors,the low efficiency of industrial coordination and support,unequal access to public service facilities,and the insufficient use of land.Therefore,based on the strategic framework of urban-rural integrated development,it is necessary to continuously promote Chinese modernization through high-quality integrated urban-rural development from the perspectives of deepening institutional coordination,expanding the application of digital intelligence in urban and rural industries,optimizing public services,and improving land management. 展开更多

The suburbs surrounding metropolitan areas are the priority area for urban-rural integration development where functional optimization is essential to reconcile growing urban demands with sustainable rural development.Rural functions are changing substantially and vary significantly across areas in the practice of high-quality urban-rural integration development era.How to make use of the advantages of different rural functions and achieve optimized combination of functions are actual problems that urgently need to be solved.The paper analyzed the process of urban-rural integration through the identification of urban-rural integration interfaces and evaluated the multifunctional transformation of rural areas in the Chengdu-Chongqing Economic Circle(CCEC)with a fixed weight evaluation model.The differences in rural functions analyzed with the Theil index reveals the characteristics and sources of differences in the“production-living-ecology-culture”functional areas in the CCEC.The research results show that:(1)The spatial distribution characteristics of rural functions in the CCEC are obvious,and agricultural production clusters dominate the Chengdu Plain and eastern Chongqing,contrasting with ecological conservation zones along the Yangtze River system,while cultural heritage hubs concentrate in economically vibrant tourism corridors.(2)The overall regional differences in rural functions are mainly due to intra-regional differences;in terms of the contribution rate,the contribution rate of intra-regional differences in agricultural production,ecological conservation,and cultural heritage functions is much larger than that of inter-regional differences,whereas the inter-regional differences in human living functions are larger than those of intra-regional differences.(3)Based on the research results,the study area is divided into 14 functional types,which can provide scientific basis for improving the spatial layout and high-quality development of rural functions in the CCEC.These insights advance theoretical understanding of mountainous-urban transitional areas while informing practical strategies for high-quality integrated development. 展开更多

Based on the comprehensive analysis of data from petrology and mineralogy,well logging,seismic surveys,paleontology,and geochemistry,a detailed research was conducted on paleoenvironmental and paleoclimatic conditions,and modeling of the source rocks in the second member of the Eocene Wenchang Formation(Wen 2 Member)in the Northern Shunde Subsag at the southwestern margin of the Pearl River Mouth Basin.The Wen 2 Member hosts excellent,thick lacustrine source rocks with strong longitudinal heterogeneity and an average total organic carbon(TOC)content of over 4.9%.The Wen 2 Member can be divided into three units(I,II,III)from bottom to top.Unit I features excellent source rocks with Type I organic matters(average TOC of 5.9%)primarily sourced from lake organisms;Unit II hosts source rocks dominated by Type II2 organic matters(average TOC of 2.2%),which are originated from mixed sources dominated by terrestrial input.Unit III contains good to excellent source rocks dominated by Type II1 organic matters(average TOC of 4.9%),which are mainly contributed by lake organisms and partially by terrestrial input.Under the background of rapid subsidence and limited source supply during intense rifting period in the Eocene,excellent source rocks were developed in Wen 2 Member in the Northern Shunde Subsag under the coordinated control of warm and humid climate,volcanic activity,and deep-water reducing conditions.During the deposition of Unit I,the warm and humid climate and volcanic activity promoted the proliferation of lake algaes,primarily Granodiscus,resulting in high initial productivity,and deep-water reducing conditions enabled satisfactory preservation of organic matters.These factors jointly controlled the development and occurrence of excellent source rocks.During the deposition of Unit II,a transition from warm to cool and semi-arid paleoclimatic conditions led to a decrease in lake algaes and initial productivity.Additionally,enhanced terrestrial input and shallow-water,weakly oxidizing water conditions caused a significant dilution and decomposition of organic matters,degrading the quality of source rocks.During the deposition of Unit III,when the paleoclimatic conditions are cool and humid,Pediastrum and Botryococcus began to thrive,leading to an increase in productivity.Meanwhile,the reducing environment of semi-deep water facilitated the preservation of excellent source rocks,albeit slightly inferior to those in Unit I.The study results clarify the differential origins and development models of various source rocks in the Shunde Sag,offering valuable guidance for evaluating source rocks and selecting petroleum exploration targets in similar marginal sags. 展开更多
