Spatiotemporal differentiation and influencing factors of primary,secondary,and tertiary industries integration in China's four major tea-producing regions
[Objective]Industrial integration not only enhances the overall competitiveness of the tea industry but also promotes diversified local economic development,serving as an important means to improve the new quality productive forces of agriculture and revitalize rural areas.Explor-ing the spatiotemporal evolution patterns and influencing factors of the integration of primary,sec-ondary,and tertiary industries in China's four major tea-producing regions is of significant impor-tance for promoting the upgrading of the tea industry and driving economic growth in these re-gions.[Methods]Based on the policy background of primary,secondary,and tertiary industries in-tegration,this study focused on 44 major tea-producing areas of China's four tea-producing re-gions.The entropy method was employed to measure the level of industrial integration in these ar-eas across five dimensions:actors,technology,products,business,and markets.Using spatial analy-sis techniques such as kernel density estimation,convergence analysis,the diamond model,and Multi-scale Geographically Weighted Regression,the study explored the spatiotemporal change pat-terns of industrial integration and the spatial heterogeneity of influencing factors.[Results](1)From 2012 to 2021,the level of industrial integration in four major tea regions consistently im-proved,showing a fluctuated development trend;(2)A typical pattern of spatial agglomeration and convergence was observed in these regions,with the overall level of integration increasing,the number of highly integrated areas growing,and the gap between different regions narrowing;(3)The influencing factors of industrial integration exhibited significant spatial heterogeneity:the Southern and Southwest regions are predominantly shaped by foreign investment,land resources,and educational spending;the South and North of Yangtze River regions are predominantly influ-enced by land resources.[Conclusion]Tailored strategies for integrating primary,secondary,and tertiary industries should align with the unique resources and economic characteristics of each tea-producing region.Emphasis should be placed on improving land use efficiency,investment environ-ments,and education,to enhance inter-industry synergy and cross-regional collaboration,promot-ing sustainable economic growth.
