利用1988～2009年国家统计局全国入户调查数据，本文研究了我国城市居民财产性收入的规模、组成、变化以及其对收入差距的贡献。采用基尼系数的分解方法，将每年的收入差距分解到各个收入成分的贡献，并发现与其他收入形式相比，财产性收入分布的基尼系数是最高的，对总收入差距的贡献也在迅速扩大，这一现象值得重视。本文还分别对东、中、西部地区进行了分析，发现财产性收入主要集中在东部地区。

Using 1988～2009 urban household survey data collected by National Bureau of Statistics of China, this study examines size, composition, and changes of individual capital gains and its contribution to income inequality. Using the Gini coefficient decomposition method, we decompose income inequality in each year into the contribution of each income component. Furthermore, we find that compared to other income forms, capital income has the largest Gini coefficient, and its contribution to total income inequality has been rising significantly, which requires careful attention. In addition, we analyze capital income for the Western, Central, and Eastern regions separately, and find that capital income are the grea- test in the Eastern region.
