| 摘 要： | 江苏沿海地区存在着较为显著的县(市)域经济发展差异,并且有进一步扩大的趋势.在GIS技术支持下,引入空间分析中的区域重心模型,利用人口、经济(GDP)、外资(FDI)等主要重心的时空偏离,对1996-2006年江苏省沿海地区经济之间的空间差异进行了实证分析.结果表明,10年间江苏沿海地区总体上经济空间差异较大;经济重心与外资重心有较大偏移;江苏沿海地区的经济、外资重心较人口重心有显著的空间偏移;人口重心北移趋势明显,经济重心和外资重心从1999年开始一直向南偏东方向位移.

| Abstract: | There are remarkable disparities in economic development in the coastal regions of Jiangsu Province,and the economic gap tends to be widening.This paper conducts an empirical analysis of the regional economic disparities in coal areas of Jiangsu Province since 1996 by applying the regional gravity center model.Such a study is made with the support of GIS technology,and some other major indexes such as population,GDP and FDI.Research results show that the coastal regions of Jiangsu Province have generally ex... |
