摘要
基于核密度估计方法,给出居民收入分布变迁测度及其影响因素分解的相对收入分布方法。使用中国健康和营养调查的微观居民收入数据,实证分析中国居民收入分布及其变迁的特征、过程及其影响因素。实证结果显示:中国居民收入分布变迁的速度与经济体制改革进程相对应;经济增长因素是引起居民收入分布变迁的主要因素,在提高总体居民收入水平的同时加剧了居民收入分布的极化程度;收入分配因素对居民收入分布变迁的作用相对较弱,但有一定的减贫或缩小居民收入差距作用。
Basing on the kernel density estimation, the paper introduces distribution method to measure income distribution changes. Using the data of the relative income ＂China Health and Nutrition Survey＂, the paper analyzes the characteristics of income distribution, its changing process and economic meanings. Furthermore, by decomposing the relative income density function, the paper measures the impacts of growth factors and distribution factors on the income distribution changes. The empirical results show that the changes of income distribution in China closely correspond to the economic system reform process. Economic growth is the most important factor which enhances the overall income level but also raises the polarization of income distribution. Comparing to economic growth, income distributing policies play a much weaker role on income distribution changes but can help to reduce the poverty or narrow the residents＂ income gap in China.
