Analysis Of County Economic Differences And Influencing Factors Based On GIS

The imbalance of regional development is a universal problem in the current global economic development.Studying regional economic development differences from county-level units can better reveal the evolution of local economic development.In recent years,the imbalance of economic development amon g counties in Henan Province is remarkable.The research on the differences in the development of county economy in Henan Province is of great significance to promote the coordinated development of county economy in Henan Province.Under this background,supported by the theory of surveying and mapping geographic information,based on the 2005-2020 Statistical Yearbook and government work report of Henan Province,this paper comprehensively integrates mathematical statistics,GIS spatial analysis and Geodetector model to measure the differences in the development of county economy in Henan Province from the two dimensions of time and space,detect its driving mechanism,and put forward suggestions for the existing problems.The main conclusions are as follows:(1)The absolute difference of county economic development in Henan Province is gradually expanding with the passage of time,and the relative difference tends to increases and then decreases with time;The county economic difference shows a trend of polarization.With the fastest developing Xinzheng City is 12 times faster than the slowest developing Anyang County;The counties with higher-than-average development speed are mainly concentrated in the surrounding areas of economically developed cities,while the number of counties with lagging development speed is relatively high.(2)The development of county economy in Henan Province shows a strong spatial positive correlation and significant agglomeration;The pattern of cold and hot spots in the development of county economy is relatively stable.The hot spots are mainly distributed in the northwest region with Zhengzhou and Jiyuan as the core,and the number of counties continues to increase.While the cold spots are mainly distributed in the eastern part of Henan Province,and the number of counties continues to decrease;The overall moving direction of the center of gravity of county economy is southeast,and it shows a diamond-shaped trend with the passage of time.(3)The main factors affecting the economic development of the county are the value added of secondary industry,economic base,per capita disposable income and general public budget expenditure;The resident population,employees in secondary and tertiary industries,and the value added of primary industry have a negative effect on the development level of county economy in Henan Province.There are interactions among the influencing factors.The explanatory power of the interaction of any two influencing factors on the economic development of the county is manifested as two-factor enhancement or non-linear enhancement,mainly two-factor enhancement.The dominant interaction factors are the added value of the secondary industry ∩ resident population,economic base ∩ the added value of the secondary industry.Based on this,in the process of development,the government should increase investment to retaining human resources and consolidate the real economy dominated by the secondary industry,optimize the economic development pattern,and promote coordinated economic development.
