中国草莓主产区布局变迁特征及影响因素研究OA

This paper selects the major strawberry production as the research object,employs the industrial concentration index,comparative advantage index,and Moran's index to analyze the layout from 2002 to 2022 of major strawberry production,and uses the Dagum Gini coefficient to decompose the regional differences of comparative advantages for strawberry production,and constructs a panel model to explore the factors affecting the changes in strawberry production layout in China.The results show that:(1)Strawberry production has gradually shifted from concentrated to dispersed,but it is still highly concentrated,and showed a significant westward and southward migration trend.Meanwhile,the number of provinces with comparative advantages in terms of scale and efficiency remained stable.(2)Strawberry production exhibits positive spatial autocorrelation,with high-high aggregation and low-low aggregation characteristics.(3)The overall differences of strawberry production tended to shrink,the proportion of inter-regional differences first decreased and then increased,and the proportion of intra-regional difference was relatively stable.(4)The changes in strawberry production layout were the result of the combined action of supply-side and demand-side factors.Supply-side factors generally dominated the layout changes of strawberry production,especially natural conditions,while the role of demand-side factors was relatively weak.The findings can provide valuable insights for localities to leverage their comparative advantages and guide the optimization of strawberry production layout.
