A Study On Spatial Correlation And Spillover Effects Of County Economic Development In Hunan Province

In economic development,the county is closely linked to neighboring counties through the circulation of materials,capital,and information.The balanced development of the county economy is an important way to solve the main contradictions in our society.As a major province in central China,the study of county economic development in Hunan Province is helpful to understand the growth mode of county economic development,to provide theoretical support and practical evidence for the efficient and coordinated development of county economy in Hunan Province,and to provide important reference for county economic development in other central provinces.This paper is divided into five parts: The first part is the literature review.Starting from the domestic and foreign research literature on regional economy,county economy and spatial effects,the existing literature is sorted out and summarized,which is the literature basis of this paper.The second part is related theory discussion,which defines county economy and analyses two kinds of economic growth theories,carries on the theoretical analysis of the influencing factors of county economy,and finally carries on the relevant theoretical analysis of regional economic development as the theoretical basis of this paper.The third part is the study on the current situation of county economic development in Hunan Province.The Topsis model based on the entropy weight method is used to analyze the comprehensive strength of county economic development.The difference of county economic development is preliminarily analyzed by descriptive statistical method and development difference index method,and the reasons for the difference are summarized.The fourth part is the spatial effects of county economy in Hunan Province.ESDA method is used to test the spatial correlation.Spatial panel model is used to study the influencing factors of county economy development.Partial differential decomposition method is used to decompose the spatial spillover effect.The fifth part is policy recommendations.According to the results of theoretical and empirical analysis,relevant policy recommendations are put forward to promote the development of county economy in Hunan Province,with a view to promoting the efficient and coo rdinated development of county economy in Hunan Province.The results show that: Firstly.There is a phenomenon of unbalanced development of county economy in Hunan Province.The disparity of county economic development is not only caused by the disparity of county economic development within the four regions,but also by the economic disparity among the four regions.Secondly,there are significant spatial correlation and spatial agglomeration effects in Hunan County Economic development.Third,the influencing factors of county economic development in the four regions are different,and only the Changsha-Zhuzhou-Tan region has significant spatial correlation.Fourthly,the spatial spillover effect of county economic development in Hunan Province is remarkable.The innovations of this paper are as follows: Firstly.While analyzing Hunan as a whole,the spatial correlation of county economic development in Changsha-Zhuzhou-Tan region,Dongting Lake region,Western Hunan region and Southern Hunan region with different sub-samples is studied,and the research perspective is unique.Secondly,the research methods in this paper include comprehensive evaluation,difference index method,ESDA method and spatial econometric model.The spatial characteristics of Hunan county economic development are studied from various angles and methods,which makes the conclusions more stable and reliable.Thirdly,this paper studies the law of Hunan county economic development from the aspects of comprehensive strength research,differentiation analysis,spatial correlation,spatial spillover effect and so on.The research idea is novel,and the research is more convincing.
