Abstract:

The purpose of the study is to analyze the spatial variation of 〖JP2〗economy in PanYangtze River Delta.〖JP〗The economic growth in each region not only 〖JP2〗depends on its own characteristics,but also on the neighborhood〖JP〗 regions which it belongs to.Unfortunately,the traditional approaches 〖JP2〗suppose that each region is independent〖JP〗 from others,so they just evaluate the regional disparity variations of "isolated" regions and cannot tell the dynamics of interrelated regions.Methods of ESDA were employed,which 〖JP2〗could incorporate spatial〖JP〗 effects into the analysis of regional disparities,identify global and local disparities at the 〖JP2〗regional scale and visualize〖JP〗 the spatial distribution and patterns through Moran scatter plots or LISA maps.In order to avoid the variation instability of the variable of per capita GDP,methods of spatial autocorrelation indicators adjusted by Empirical Bayes was employed. This paper investigated the spatial dynamics of regional disparities at the municipal level in PanYangtze River Delta by analyzing per capita GDP data,1999~2008.The results indicated that the economy development showed obvious spatial cluster pattern in PanYangtze River Delta.The value of EBI showed a trend of increased volatility; the spatial transfer of clusters and outliers showed definite rules; the economy development showed obvious local spatial disparity pattern.The study indicated the feature of the Yangtze River Delta region with highvalue and the new expansion provinces with lowvalue
