江苏省县域经济增长收敛性和空间格局分析

The Convergence and Spatial Pattern Analysis on the County Economic Growth in Jiangsu Province

以人均国内生产总值作为变量指标,通过计算测度1996～2009年江苏省县域经济增长的收敛性,并利用全局Morans’I指数和空间联系局域指标(LISA)进行空间自相关分析。结果表明,江苏省县域经济增长的空间聚集效应增强,集聚区域间的经济差异不断拉大,经济增长收敛性在空间格局上表现出明显的苏南、苏北间发散和两大区域内部收敛的趋势。

Taking per capital GDP as the variable target,estimates the county＇s economic growth convergence in Jiangsu Province during 1996-2009,and uses the global Moran＇s I index and LISA to carry on the spatial autocorrelation analysis.The results show that that the spatial aggregation effects of county economic growth has been increased,the concentration of inter-regional economic disparities continue has been widen,the economic growth astringency displays obvious divergence between Southern Jiangsu and Northern Jiangsu and the trend of convergence within the two large areas in Jiangsu Province.
