中国农业产业链供应链韧性水平的区域差异、动态演进及空间收敛特征OACHSSCD

This paper measures the resilience of China's agricultural industrial chain and supply chain across 31 provinces from 2012 to 2021 by using the entropy weight method,and further examines their regional differences,dynamic evolution,and spa-tial convergence characteristics by employing the Dagum Gini coefficient and its decomposition method,kernel density estimation,Moran's Index,and spatial econometric models.The results go as the following:(1)During the sample period,the overall level of ag-ricultural industrial and supply chain resilience in China exhibits a sustained upward trend,with pronounced gradient disparities across the four major regions and substantial interprovincial heterogeneity.(2)Interregional differences constitute the primary source of overall differences,their contribution declines over time,while intraregional differences are particularly salient in the east-ern and western regions.(3)Interprovincial differences in resilience continue to widen,but no multi-polarization phenomenon has emerged.(4)Although neither national nor regional resilience levels displayσ convergence,both absolute and conditional β conver-gence are observed,suggesting a long-run tendency toward region-specific steady states at heterogeneous convergence speeds.Moreover,agricultural economic scale,population density,government support,and regional market size exert significantly hetero-geneous effects on resilience across regions.
