公平收入差距与收入分配公平感*

本文基于CGSS的调查数据探索公平收入差距与微观收入分配公平感的相关关系。结果表明，公平收入差距和微观收入分配公平感之间存在倒U型关系，当实际收入不断接近自我感知的公平收入时，收入分配公平感不断提升，并在收入等于公平收入处达到最高；此后，随着真实收入的继续增加，分配公平感不升反降。改变模型设定、控制变量形式等方式都证明了该结果的稳健性。此外，异质性分析表明，受教育程度、工作状态和不平等归因对两者之间的关系存在调节作用。这一研究将为提升居民对于收入分配的公平感知提供有效的理论依据。

GAP BETWEEN REAL INCOME AND SELF PERCEIVED FAIR INCOME AND PERCEPTION OF DISTRIBUTIVE JUSTICE

Based on China General Social Survey(CGSS) Data,this paper explores the correlation between the gap between real income and fair income and micro perception of distributive justice.Our results confirm an inverted “U shape” relationship between the two.As the actual annual income increases towards the self perceived fair income from below,perception of distributive justice is ascending constantly,and then reaches the peak when real income is around fair income.After that,as real income continues to increase,perception of distributive justice no longer continues to rise and starts to fall instead.This relationship is robust after we change our model setting and the form of control variables.In addition,heterogeneity analysis reveals that education,work status and inequality attribution of the respondents have a regulatory effect on the relationship between the two.This study offers a positive evidence based foundation on how to improve residents' perception of distributive justice.
