江苏省沿江市(县)利用外资时空差异及其影响因素

根据江苏省沿江36个市 (县)90年代以来实际利用外资额的标准差与变差系数的分析,揭示出这一区域在实际利用外资不断地发展过程中,各市（县）的差距存在着阶段性的变化;并由区域空间增长的差异,得出苏州市、无锡市地区和南京市两大投资核心的形成和分散的趋势。同时,主要借助于定量分析方法,研究表明,此区域实际利用外资额空间分布的不平衡性特性主要归结于各市（县）的投资环境的地域差异,特别是各市（县）的一般性的经济因素起着关键作用,而这正成为了江苏省沿江市（县）改善投资环境的重点。

ANALYSIS ON THE DIVERGENCE AND TEMPORAL-SPATIAL STRUCTURE OF THE FOREIGN INVESTMENT IN CITIES AND COUNTIES ALONG THE YANGTZE RIVER IN JIANGSU PROVINCE

The main purpose of this research is to study the evolution process and spatial disparities of foreign investment in cities and counties along the Yangtze River in Jiangsu Province after 1990 year. By studying of standard deviation and warp coefficient of foreign investment in this region, three stages of foreign investment are divided. These three stages are the expanding stage(1990/1993 -1999), the dropping stage (1999-2001)and the high rising stage (after 2001). The spatial disparity of foreign investment distribution in this region and its causes are also analyzed with the aid of Factor analysis in which 36 counties and cities of this region are chosen as the case. The four factors are abstracted from 14 varibles and the first twins are general economic factors and they are more important than the laters. The results suggest that the regional disparities of foreign investment are mainly resulted from the difference in geographic and human situations and the regional policies to attract foreign investment should focus on improving these economic factors.
