安徽省区域经济差异的时空演变及影响因素

Spatial-temporal Evolution and Influencing Factors of Regional Economic Disparities in Anhui Province

区域经济发展差异是我国经济发展中长期面临的主要问题之一,科学研判区域发展形势,精准施策,对实现区域经济均衡发展,推进五位一体建设进程具有重要意义。采用泰尔指数和空间自相关等方法,分析2011—2019年安徽省经济差异的时空演变特征,同时引用地理探测器模型深入对比分析各因素的影响力,分析影响区域经济差异的主要因素。研究表明:安徽省区域经济差异呈“先降后升再降”的趋势,整体上区域经济差异不断缩小,皖中城市经济差异不断扩大;从空间演变格局来看,区域经济发展水平呈空间正相关性。经济发展水平呈一定的“阶层固化”的态势,中东部经济发展水平相对较高,西北部地区经济发展有待提高;从各影响因素的作用强度来看,投资状况是影响安徽省经济差异的主导因素,其次为产业结构与对外开放程度。

The disparities of regional economic development is one of the main problems that our economy faces in the long term.Scientific research and judgment of the regional development situation and precise implementation of policies are of great significance for achieving balanced regional economic development and promoting the five-in-one construction process.Theil index and spatial autocorrelation and other methods are used to analyze the spatial-temporal evolution characteristics of the economic disparities in Anhui Province from 2011 to 2019.At the same time,the geographical detector model is used to compare and analyze the influence of various factors,and analyze the main factors affecting regional economic disparities.Research shows that the regional economic disparities in Anhui Province show a trend of"decline,rise and decline again".As a whole,the regional economic disparities conti-nue to shrink,and the urban economic disparities in central Anhui continue to expand.From the perspective of the spatial evolution pattern,the regional economic development level is spatially positively correlated.The level of economic development is in a state of"stratum consolidation".The economic development level in the central and eas-tern regions is relatively good,and the economic development in the northwestern regions needs to be improved.From the perspective of the strength of various influencing factors,investment status is the leading factor affecting the economic disparities in Anhui Province,followed by the industrial structure and the degree of opening to the outside world.
