差异化的中国“美貌溢价”——来自CFPS2018的证据

Differentiated Chinese“beauty premium”:evidence from CFPS2018

通过匹配CFPS2018年数据库中的受访者外貌评分,选取颜值指标并将其与微观数据匹配,利用Stata工具实证研究颜值对个人收入的影响。研究结果表明,颜值对个人收入具有显著的正向影响,且颜值对女性的影响程度大于男性,但是颜值对于具有大学教育背景的受访者而言,作用并未增强。利用工具变量解决内生性偏误后,颜值对个人收入具有显著正向影响的结论依然稳健。机制分析表明,颜值可以通过增强社会信任和提高互联网使用频率促进个人收入增长。

By matching the appearance score of interviewees in CFPS2018 database,the appearance level index is selected and matched with micro-data,and the impact of appearance level on personal income is empirically studied using Stata tool.The results show that physical appearance has a significant positive effect on personal income,and the effect is greater for women than for men,but not for those with a college education.After using instrumental variables to solve endogenous bias,the conclusion remains robust that appearance level has a significant positive effect on personal income.The mechanism analysis shows that appearance level can promote personal income growth by increasing social trust and increasing the frequency of Internet use.
