中文摘要：

根据江苏沿海县域经济单元2002—2011年人口与GDP统计数据,计算了县域经济体的基尼系数、变异系数以及泰尔指数,定量分析了研究时段江苏沿海县域经济发展差异性的时空演化趋势。结果表明,沿海县域的产业结构特征表现为以下几个方面。江苏沿海12个县域经济整体经济发展差距经历了先增后减的过程,2009年后各县市之间以及各地级市之间的差距普遍减小;随着时间的推移,南通、盐城、连云港内部的县域经济发展水平具有一致性,地级市内部县域产业结构亦具有一致性,反映了产业结构对于县域经济的影响;三次产业增长率呈现出由第一产业向第二产业再向第三产业推移的产业演变规律。

英文摘要：

On the basis of the population data and GDP during 2002--2011 ,the measure method of Gini variation coefficient and Theil index was suggested to analyze the inequality in Jiangsu coastal counties economy and the tendency of temporal and spatial variation quantitatively. Taking industrial structure of countries, we found the conclusions which were sumnmrized as follows. First of all,the inequality of Jiangsu coastal counties had a course of ＂first increased and then deereased＂.After 2009,the gaps of countries narrowed.Then the similarity of counties economy and industrial structure increased with time. FinaBy,it was obvious that the rate of growth transferred from primary industry to secondary industry, and shift into tertiary industry,which called the regulation of industry evolution.
