摘　　要：运用收入转换矩阵和P指数实证分析了我国城乡居民的收入流动性及其对长期不平等的影响,结果表明:总体上看,我国居民收入地位的互换程度在加剧。从各阶层的流动来看,底层和顶层相对固化,中国较高的收入流动性主要是以中间收入阶层的互换为主,特别是以中间阶层的收入状况恶化为主;各个时期的收入流动都对收入不平等的降低起到了显著的正向影响,改革前期的影响度要远远高于改革后期;从城市和农村的对比来看,农村收入流动对长期不平等的改善远远超过城市。本文所蕴含的政策含义是改善收入分配政策体系,促使顶层和底层能打破固化趋势、扩大中等收入群体的范围应是我国未来社会政策的主要方向。The urban and rural residents＇ income mobility and its influence on long-term income inequal- ity in China are analyzed based on the income transform matrix and P index. The results are as fol- lows ： as a whole, the degree of interaction of residents＇ income position is exacerbating, the middle in- come group plays a major role in the interaction of income position, and the income mobility of the low and high income groups has a trend of solidification; the income mobility in different periods has a great positive effect on the reduction of the income inequality, and the effect degree at the initial stage of reform is much higher than at later stage; and the effect is better in rural area than in urban area. The results show that the strategies such as breaking the solidification of the low and high income groups, expanding the middle income group and improving the income distribution system should be taken in the future.
