本研究试图利用来自四轮中国家庭追踪调查的家庭人均收入数据, 分析2012年至2018年中国收入不平等的趋势和模式。 研究发现, 这一时期中国收入不平等出现了加剧的趋势。 基于Shorrocks分解法和Lerman-Yitzhaki分解法, 研究发现工资收入和转移收入对总体不平等的百分比贡献占主导地位, 同时发现工资收入对减少收入不平等有正向作用, 而转移收入则相反, 即对整体收入分配具有负面影响。
This study attempts to analyze the trend and patterns of income inequality in China between 2012 and 2018 by using household income per capita data which comes from four waves China Family Panel Studies. The study finds that China income inequality appears an increase trend during this period. Based on Shorrocks decomposition approach and Lerman-Yitzhaki decomposition approach, the study finds that that wage income and transfer income have dominant percentage contribution to total inequality, and also finds that wage income have a positive role in decreasing income inequality and transfer income have a counter-intuitive negative effect on equalizing overall income distribution.
