摘要: 应用探索性空间数据分析(Exploratory Spatial Data Analysis,ESDA)及变异系数方法,取江苏省65个县(市)的经济指标为测度因子,对江苏省县域经济的总体发展趋势、全局及局部空间差异进行研究,发现:各县市经济存在强烈地空间自相关性且空间差异增大,呈明显的二元结构特征,极化态势与经济差异变化趋同;LISA分析显示苏南和苏北地区已形成了与周边地区显著相似的块状面域,南北差异仍是导致省内经济差异的主要因素,南北的极化作用明显大于扩散,在循环累积因果的作用下南北极化的“哑铃状”空间格局将进一步扩大。

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
