Analysis of County Economic Spatial-Temporal Disparities in the Circum-Taihu Lake Economic Zone
Abstract:Coefficient of variation,Theil index and statistical techniques were applied to analyze the evolution of economic spatial-temporal disparities and spatial economic structure in Circum-Taihu Lake Economic Zone by using county as a spatial unit and per capita GDP as measuring index for the level of regional economic development.Analysis of coefficient of variationand Theil index indicated that the interregional inequalities in Circum-Taihu Lake Economic Zone have been narrowed. By the decomposition of Theil index, it shows that the interregional inequalities between the southern Jiangsu(Sunan)and the northern Zhejiang (Zhebei) have been narrowed,the intraregional inequalities of the southern Jiangsu(Sunan) is the major proportion of the global spatial disparity and the intraregional inequalities of the nothern Zhejiang(Zhebei) is the least.From the temporal change of the spatial autocorrelation,we found that cities and countries in Circum-Taihu Lake Economic Zone which develop fast tends to concentrate.Contrasting the variation tendency of CV and Moran’s I,they are reversed during the study period from 2004 to 2013.Moran's I scatter plot pided the 21 counties of Circum-Taihu Lake Economic Zone into HH counties and the counties that has no space for inspection by the general stochastic process.HH counties have increased and are located in the Northeast Circum-Taihu Lake Economic Zone.To illustrate the preposition that county and city trajectories of economic growth determine the changes regional inequality, each county and city per capita GDP was compared to the corresponding Circum-Taihu Lake Economic Zone average in 2004,2007,2009 and 2013 to see if a county or city had been converging to the average or perging from 2004-2007,2007-2009 and 2009-2013. We find four regional types are pided by the trends of all cities and counties such as downwardly converging , upwardly converging, upwardly perging and downwardly perging .
