Children's education and women's employment are widely discussed issues. This paper attempts to analyze the impact of female labor participation on children's education. First, the theoretical hypothesis of the impact of female labor participation on children's years of education is proposed, and then empirically tested using the 2016 CFPS database. To overcome endogenous effects, we use the labor force participation rate of other women in the same community as an instrumental variable for female labor participation in the family, and empirically test the impact of female labor participation on children's education. The results show that urban women's participation in labor will reduce their children's education level, while rural women's participation in labor does not affect their children's education level.
