在过去的几十年里，性别平等意识有了显著提升，女性在教育和工作场所的参与度也在增加，但性别收入差距仍然普遍存在。在一些国家，这种差距已经缩小，但在许多其他地方，尤其是发展中国家，性别收入差距仍然很大。基于这种现状，本文聚焦于分析性别收入差距的影响因素。本文采用中国家庭收入调查（CHIP）中选择2008、2013、2018三年数据进行实证研究，分析性别收入差距的影响因素。研究发现，性别收入差距的影响因素有多种方面，包括但不限于年龄、学历、健康状况、工作经验、婚姻状况、单位所有制等。本文先后验证了三条假设。首先，通过对数据进行回归整理，推翻假说1：随着时间推移，男性与女性之间的收入差异会越来越小；其次，通过进行对单位所有制的异质性分析，验证假说2：在国有部门中，男女收入上的差异要小于非国有部门；最后，针对受教育年限这一变量进行工具变量法的稳健性检验，验证假说3：不同学历男女收入差异不同，高学历男女收入差异小于低学历收入差异。

In the past few decades, there has been a significant increase in awareness of gender equality and in women's participation in education and the workplace, but the gender income gap remains widespread. In some countries, the gap has narrowed, but in many other places, particularly in developing countries, the gender income gap remains large. Based on this situation, this paper focuses on analyzing the influencing factors of gender income gap. This paper uses data from the China Household Income Survey (CHIP) in 2008, 2013, and 2018 to analyze the influencing factors of gender income gap. The study found that the gender income gap has many factors, including but not limited to age, education, health, work experience, marital status, unit ownership. Three hypotheses are tested in this paper. First, through regression of the data, hypothesis 1 is disproved: over time, the income gap between men and women will become smaller and smaller; secondly, hypothesis 2 is verified by a heterogeneity analysis of unit ownership. In the state-owned sector, the income gap between men and women is smaller than that in the non-state-owned sector; finally, a robust test of the instrumental variable method is conducted for the length of schooling. Hypothesis 3 is verified: the income gap between men and women with different educational backgrounds is different, and the income gap between men and women with higher educational backgrounds is smaller than that between women with lower educational backgrounds.
