摘　　要：在分析江苏区域经济和外商投资的空间分布特征基础上,将表征经济发展的GDP和表征外商投资的FDI同时引入CES生产函数模型,探讨了不同时期两者的内在时空关系,得到以下结论:①区域经济空间格局维持"南高北低"稳定态势,外商投资格局则呈现出由苏南向苏中、沿海和苏北地区逐渐蔓延的态势而导致两者的对应程度趋于瓦解;②CES模型显示外商投资逐步发挥对经济的独特促进作用,且其边际效应高于国内投资而成为影响经济增长的一个重要外在因素;③在假定国内投资与有效劳动投入不变的前提下,虽然增加外商投资有利于沿海和苏北的经济增长,但现阶段并未引起江苏经济空间格局"南高北低"的波动。The level of foreign direct investment plays a different role in regional economic growth at different stages, which makes it crucial to measure the influence on regional economic growth of this effect above quantitatively. Based on the analysis of spatial distribution characteristics of Jiangsu regional economy and foreign investment, this paper introduces GDP and FDI into CES Production Function simultaneously, and explores the inner temporal relationship between them. After study above, the main conclusions have been summarized as follows： （1） space structure of regional economy maintains a stable situation as ＂high in the south and low in the north＂, while the pattern of foreign investment demonstrates a situation of gradual spreading from the south to the middle and from the coastal and to the north of Jiangsu, which makes the corresponding degree of the two above patterns tend to collapse; （2） CES production function reveals that foreign investment plays a unique role on promoting economy gradually, and marginal effect is higher than domestic investment making it an important external factor on economic growth; （3） Although it is beneficial to the economic growth in the coast and north of Jiangsu to increase foreign investment on the premise of assumed invariability of domestic investment and effective labor input, it doesn＇t induce a fluctuation of economic space pattern as ＂high in the south and low in the north＂ in Jiangsu at present stage.
