安徽省县域经济空间差异及演化分析

Spatial evolution analysis of county-level economy in Anhui Province

基于2008-2017年安徽省61个县域的人均GDP,运用空间自相关Moran′sI指数和Getis-Ord G指数分析县域经济的空间聚集性,通过标准差椭圆研究经济发展空间分布的中心性和方向性,分析安徽省县域经济空间差异及演化.结果表明,安徽省县域经济发展水平呈现由东南向西北递减的格局;经济发展存在显著空间正相关,近年来发展差异程度逐步扩大,经济热点地区集中在东南部;经济重心较为稳定,有缓慢向东转移趋势,标准差椭圆呈西北-东南走向,呈空间收缩趋势.从优化产业结构、因地制宜制定发展政策和加强地域合作等方面提出建议.

Based on the per capita GDP of 61 counties in Anhui Province from 2008 to 2017,the spatial aggregation of county-level economy was analyzed by using spatial autocorrelation Moran′s I index and Getis-Ord G index,the standard deviation ellipse were used to analyze the centrality and directionality of the spatial distribution of economic development,and analyze the spatial difference and evolution of county economy in Anhui Province.The results show that the development level of county economy in Anhui Province shows a decreasing pattern from southeast to northwest,there is a significant positive spatial correlation in economic development,the development differences gradually expand in recent years,the economic hot spots are concentrated in the southeast.The economic center of gravity is relatively stable with a slow eastward transfer trend,the standard deviation ellipse shows a northwestsoutheast trend,showing a spatial contraction trend.Suggestions are put forward from the aspects of optimizing industrial structure,making development policies according to local conditions and strengthening regional cooperation.
