Analysis On The Characteristics Of Spatial Structure And Influncial Factors On County Economy In Hunan Province

Due to the differences in rich natural resources and location conditions of county units,the unbalanced development on county economic is caused.Therefore,how to promote the development on county economy coordinately and rapidly is a problem worth studying.In this paper,the center of gravity model and spatial auto correlation analysis were used to measure the spatial correlation of county economy in Hunan Province from 2005 to 2017,which analyze the spatial correlation and spatial heterogeneity of the county economies.Through the multiple linear regression model,the influencing factors of the county economy in Hunan Province are further revealed.The specific conclusions are as follows :Firstly,on the whole,there were problems such as the uneven of county economy,weak overall economic strength,and unreasonable industrial structure in Hunan Province.Secondly,through the analysis on the characteristics of spatial structure on county economy in Hunan Province,it was found that the regional differences were significant.The Changsha-Zhuzhou-Xiangtan areas had always been the developed regions in the years on study and were the core of economic growth in Hunan Province.The development of the western region in Hunan Province was relatively slow.Thirdly,the county economy of Hunan Province had always been located in the northeastern part of the eastern and central regions;From the perspective of the speed of gravity shift,it showed the characteristics of speed and slowness.Through the global Moran'S I index analysis,it was found that the development on county economic in Hunan Province had the characteristic of spatial auto correlations,which was significantly positively correlated,showing the characteristics of uneven distribution,meaning that the degree of the agglomeration on county economic fluctuated to a certain extent;Through the local Moran'S I index analysis,it is obvious to find that the H-H agglomeration type mainly exists in the Changsha,Zhuzhou and Xiangtan areas,while the L-L agglomeration type mainly exists in the GreaterXiangxi area.Fourthly,the influential factors on the multiple linear regression were significant.Among the selected six indicators,industrial GDP and rural per capita disposable income had a greater impact on county economy.
