Research On The Spatial And Temporal Evolution And Influencing Factors Of Urban Economic Differences And Connections In Jiangxi

Jiangxi Province,with Nanchang City as the single core province,has obvious internal differences.The northern Jiangxi city centered on Nanchang City and the southern Jiangxi city centered on Ganzhou City have obvious characteristics of difference.The economic differences between them face huge challenges for their coordinated development.Therefore,by analyzing the economic differences between cities in Jiangxi Province,this article reveals the characteristics of the spatiotemporal changes of economic differences between cities;at the same time,it explores the connection pattern between cities with the magnitude of gravity between cities.Combining the characteristics of the temporal and spatial changes of economic differences between cities and the inter-city connection pattern,some suggestions and countermeasures suitable for the coordinated development of cities in Jiangxi Province are proposed,which will promote the strengths and weaknesses of the cities within the province and develop in a balanced manner,thereby enhancing the overall provincial competition To narrow the gap with neighboring provinces.This article mainly analyzes the characteristics of the temporal and spatial changes of the economic differences between cities in Jiangxi Province and the inter-city connection pattern.In the process of exploration,the following conclusions are drawn:(1)Firstly,using per capita GDP as an indicator,the time evolution characteristics of economic differences in Jiangxi Province are studied from the provincial scale and the prefecture-level scale of Jiangxi Province.Taking 2002 as the benchmark,the per capita GDP gap increases and the standard deviation increases.Jiangxi Province The absolute difference in economy has increased;but the coefficient of variation and the Gini coefficient have the characteristics of increasing first and then decreasing.The relative difference of the economy of Jiangxi Province increases first and then decreases.Then,the economic difference of Jiangxi Province is divided by the Theil index to obtain the economic impact of northern Jiangxi The characteristics of the largest contribution rate and the lowest contribution rate in southern Jiangxi;taking the county as the research unit,using the global autocorrelation and local autocorrelation to analyze the spatial distribution of per capita GDP.It is a low-value and lowvalue spatially distributed characteristics,mainly distributed in southern Jiangxi.(2)Based on the study of economic differences in Jiangxi Province,taking prefecture-level cities as the analysis object,studying the connections between cities in Jiangxi Province,using the gravity model as a method,calculating the gravity values between cities,and comprehensively analyzing the comprehensive quality and gravity of cities The value is derived from the characteristics of Jiangxi Province with Nanchang as the "leading" city,unbalanced urban connections,and "weak and strong and weak" connections;at the same time,the analysis shows that the cities in Jiangxi Province have a tendency to develop together,Shangrao,Fuzhou,The development of Yingtan Town Group,Pingxiang,Xinyu,Yichun Town Group,Changjiu Integration,Jitai Corridor Group,etc.(3)Aiming at the characteristics of spatio-temporal evolution of urban economic differences and spatio-temporal evolution of urban connections in Jiangxi Province,this paper proposes the coordinated development of cities from the aspects of urban industrial structure optimization,urban opening and cooperation,urban infrastructure construction,urban system reform and urban talent team construction.Based on the previous discussion of urban economy,this article uses the spatial statistical analysis method to study the spatial and temporal changes of urban economic differences,and analyzes the driving factors that affect the spatial and temporal layout;at the same time,the relationship between differences and connections is explored to explore the connection pattern between cities,Breaking the previous single research paradigm.On the basis of urban economic differences and urban connection patterns,suggestions and countermeasures for promoting coordinated development among cities in Jiangxi Province were proposed,which can be used for reference for the long-term development of cities.
