Analyzing Economic Spatial-Temporal Disparities at County Level in Jiangsu Based on ESDA-GIS

Regional economic disparities have been a hot topic in recent academic world. This paper explores the feasibility of coefficient of variance (CV) and exploratory spatial data analysis (ESDA) in investigating the spatial dynamics of regional disparities at county level in Jiangsu by analyzing per capita GDP data from 1999 to 2008. Empirical results show that the overall spatial disparities of regional economy in Jiangsu have been increasing throughout the study period. The polarization effect of Jiangsu is beyond its spread effect, which indicates the spatial ramifications of the whole regional economy into two different clubs through the process of cumulative causation.
