Abstract: By using spatial autocorrelation analysis and statistical indicators, this paper uses a composite index constituted by 23 economic indicators for 67 counties in 1999-2007, to carry out a preliminary study on the changes in the spatial pattern evolution and the characteristics of the county level economies. The following results are obtained. First, the economic development has a strong spatial autocorrelation and the regional economic differences will increase in the future. The level of economic development and the trend of “polarization” are consistent. By the LISA analysis we can know that the counties tend to have the similar trends of narrowing the disparities of regional economy, and the disparities between the south and the north are the main reason resulting in regional economic disparities. Moreover, polarization and Dumbbell-shaped pattern will develop further because of the cumulative effects.

Key words: ESDA, Jiangsu province, regional economic disparity, spatio-temporal change, weighted coefficient of variation
