With the shift from individual to family-based mobility in rural areas,mobile children are gradually becoming an important labor pool in cities and playing an important role in urban socioeconomic development.Based on data from the China Family Panel Studies (CFPS) implemented by the Institute of Social Science Survey of Peking University from 2010-2018,this paper analyzes the impact of mobility experience on the labor market performance of mobile children in adulthood using OLS benchmark regression models and structural equation models.The findings show that mobility experience has a significant positive impact on mobile children’s work income in adulthood,and changes in educational human capital caused by mobility experience have a significant indirect impact on mobile children’s work income and occupational prestige in adulthood.In addition,the earlier the mobility occurs and the greater the distance,the stronger the mediating effect on labor market performance through increasing educational human capital.Therefore,the government should formulate relevant policies to promote the family-oriented mobility of mobile children and minimize the number of children left behind;expand the coverage of high-quality educational resources to reduce the risk of school failure of mobile children;and strengthen the educational capacity of schools and the ability of teachers to improve the educational quality of mobile children.
