| 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 re-sults are obtained.First,the economic development has a strong spatial autocorrelation and the regional econom-ic differences will increase in the future.The level of economic development an... |
