中文摘要：

在江苏城镇化进程不断深入的背景下,本文从收入来源结构视角对江苏城镇居民收入分配状况以及收入不平等的形成机理进行了研究。通过发展一种基尼系数的测算方法,测度了总收入与不同来源收入的不平等程度,并通过构建基尼系数的结构分解方法,计算了不同来源收入对总收入基尼系数的效应,研究发现：不同来源收入不平等对总收入不平等的边际影响程度存在一定差异及动态变化特征。本文研究的政策涵义为：促进江苏城镇居民共同富裕战略的实现需要关注收入增长中不同来源收入不平等的调节,特别是对于不平等程度较高的财产性收入和经营性收入分配的调节。

Under the background of deepening urbanization In Jiangsu province, the paper studies town residents＂ income distribution inequality and the formation mechanism of urban residents＂ income inequality from the perspective of the structure of income sources in Jiangsu Province. The paper measure the extent of inequality in total income and income from various sources by the Gini coefficient method, and then calculate the effects of different sources of income to total income Gini coefficient according to right weight of different sources of revenue to total revenue, the research conclusion is： there are some differences and dynamic characteristics of the marginal effect of inequality of the different sources of income to overall level of income inequality.
