Abstract: From the view of the prefecture-level city and county, this paper analyzes the change and spatial mechanism of regional economic inequality in Jiangsu by Gini Coefficient and spatial autocorrelation method since 1978. The research reveals that since 1978 regional economic inequality is shown enlarge a trend before 2008, while after 2008 clearly narrow and the regional economy inequality of county is higher than that of the prefecture-level city. On the scale of county and prefecture-level city, regional economic inequality in Jiangsu has notable positive correlation, and constantly enhances. Spatial agglomeration is obvious in the smaller scale. A high-level agglomeration in the south of Jiangsu and a low-level agglomeration in the north of Jiangsu result in regional economic inequality and spatial autocorrelation on the scales. But in the scale of the prefecture-level city, the low-level agglomeration in the north of Jiangsu is the main reason to lead to regional economic inequality and spatial correlation, while in the scale of county, the high-level agglomeration in the south of Jiangsu is the key cause. Hence, we should pay more attention to regional inequality of county, focusing on improving the economic level in under-developed areas at the scale of prefecture-level city and promoting spatial diffusion in higher-developed areas at the scale of county.

Key words: regional economic inequality, spatial scales, spatial association, regional pattern, Jiangsu
