文章以我国居民个人收入为研究对象，测算了三种收入不平等指数，并按收入来源法对其进行了分解。研究表明：2009年我国居民收入的不平等程度是比较高的，且基尼系数城镇低于农村；从不平等指数的分解结果来看，工资收入扩大了总收入的不平等；退休金收入减小了居民收入不平等。%Taking the personal income of Chinese residents as the object of study, this paper estimated three types of income inequality index, and decomposed them with income source method. The study showed that: Chinese residents' income inequality is relatively high in 2009, and the urban Gini coefficient was lower than rural areas;from the inequality index decomposition results, wage income expanded the inequality;pension income decreased the inequality.
