湖南省县域经济高质量发展的时空差异与分布动态OA

Using the data of 122 counties(cities,districts)in Hunan Province from 2010 to 2024,this paper constructed an evaluation index system for high-quality development of county economy based on the new development philosophy.The entropy weight-TOPSIS method,Moran's I index,and kernel density estimation were adopted to systematically analyze the spatial-temporal differences and distribution dynamics of high-quality development of county economy in Hunan Province.The results showed that during the study period,the high-quality development of county economy in Hunan Province presented fluctuating growth and staged differentiation,which was mainly driven by opening-up and coordination.However,innovation and sharing exhibited shortcomings,and green development acted as a bottom-line constraint.The spatial pattern of county economy displayed gradient differentiation featuring leading performance in Changsha,Zhuzhou,and Xiangtan,steady development in Dongting Lake region,differentiated growth in Southern Hunan,and weak development in Western Hunan,with significant characteristics of high-high agglomeration and low-low agglomeration.The overall improvement was accompanied by widening gaps and increasing polarization.Accordingly,this paper proposed four optimization paths—implementing differentiated policies for different regions,upgrading the driving forces,coordinating urban-rural development,and assisting in underdeveloped counties—to narrow county development disparities and facilitate the coordinated development between regions in Hunan Province.
