| 摘 要： | 通过回顾城市经济区划分的基础理论,选取与城市发展有关的20个指标,对江苏省13个地级市作了主成分分析.按照城市综合竞争力的大小排名选取中心城市,并利用基于GIS的可达性分析,计算最小时间成本,确定各个中心城市的影响边界,将江苏省划分成3个经济区.这一划分结果对缩小江苏省地区经济发展水平的差距具有一定的指导意义.

Then takes case of 13 cities in Jiangsu province, uses principal component analysis,and selects central cities based on analyzing the urban comprehensive competitiveness and comparing development level. This article also uses accessibility analysis to calculate the least time cost based on GIS,to fix on the effect-boundary of central cities. Finally divides Jiangsu province into 3 urban economic regions, the result will have significant meaning of reducing the gap among the development of different areas in Jiangsu. |
