摘要
文章以人均国内生产总值(GDP)为测度区域经济差异的变量指标,定量分析改革开放以来江苏省区域经济差异演变的总体水平与空间变化特征;并引用国外的区域分离系数等方法,分析了江苏省经济增长与区域差异空间格局变化的相互关系,即随着江苏省的经济增长,苏南、苏中与苏北三大区域逐渐发散趋异,城乡两大区域逐渐收敛趋同。通过各市县经济增长对区域差异收敛与发散贡献的空间分析,得出江苏省城市、农村、苏南、苏中与苏北地区分别表现为向下收敛、向上收敛、向上发散和向下发散的结论。
In the first section of this paper we provide a background for this study by reviewing the exiting domestic and intemational studies on regional economical growth and spatial structure of the economic inequality in China and Jiangsu province, and put out the primary objective of this study is to illustrate the relationship between spatial inequality evolvement and regional economic growth in Jiangsu province. In the second and third section of the paper we explain a set of methodologies of regional economic inequality and a measure of separation between groups of regions, using a consistent data of gross domestic production per capita, by taking 67 cities and counties in Jiangsu province as geography study units, this paper lnake a quantitative analysis of measuring the variety characteristic of regional economical inequality in Jiangsu province since the economic reforms of 1978 in China. By the decomposition of Theil index, it shows that the dominant sources of overall regional inequality in Jiangsu province in the gross domestic production per capita have shifted from rural - urban to intraruml inequality. The interregional inequalities among the southern Jiangsu（Sunan）, the central Jiangsu （Suzhong） and the northern Jiangsu （Subei） have been widen. In the fourth section of the paper, using a separation index recently developed measures based on regional inequality decompositions, we make a quantitative analysis of the relationship between regional economic growth and spatial structure varieties in Jiangsu province. The general conclusion that we draw from this paper of the analysis is that the continuous growth of diverging among Sunan, Suzhong and Subei areas and the continuous growth of converging between cities and counties in response to regional economic growth in Jiangsu province. To illustrate the preposition that county and city trajectories of economic growth determine the changes regional inequality, each county and city per capita GDP was compared to the con-esponding province average in 1978,1983,1993,1999 and 2003 to see if a county or city had been converging to the average or diverging from 1978 - 1983,1983 - 1993,1993 - 1999, and 1999 - 2003. We find four regional types are divided by the trends of all cities and counties such as downwardly converging （cities）, upwardly converging （countries）, upwardly diverging （Sunan） and downwardly diverging （ Suzhong and Subei）.
