A Research on Economic Spatial-temporal Variation at City-level in East China since the Year of 2000

Based on per capita GDP at city-level in east China since 2000,the paper takes cities as a basic research unit andanalyzes spatial-temporal characteristics of economic difference by applying the methods of coefficient variance,Theil indexand ESDA-GIS. The results show that the overall change of economic development patterns in east China is small since 2000.Developed regions are more clustered in the coastal and major economic areas. The basic pattern of eastern developed regionsnear and western less-developed regions away from coastal areas remains unchanged. The overall economic difference trend isreduced while equilibrium enhanced. The paper also finds that the spatial relation is enhanced and economic exchanges are clos-er among various geographical units,the economic cluster characteristic of hot spots region is obvious but its trend is becomingweaker. Finally,the paper carries out cause analysis on the formation and evolution of economic spatial-temporal pattern ineast China,and puts forward some corresponding development strategies,based on local conditions,economic and social de-velopment foundations,cluster and diffusion effect of economic region and regional development policies.
