Migrant workers are an important part of China's labor market, accounting for one fifth of China'stotal population. However, the living conditions of this huge group still need to be improved. After 40 years,why does this group still have the situation of frequent job mobility, low employment level and low socialstatus? In essence, education is the key element, and the intergenerational flow of education makes this key rolecontinue. The empirical results show that: the intergenerational flow of education does exist in migrantworkers. The education level of fathers has a significant impact on the education of children at the level of 1%,while the education level of mothers has the same trend, and there are subtle gender differences in theintergenerational impact on children's education. Therefore, we should pay close attention to the educationintergenerational flow phenomenon of migrant workers, to better promote their development and enhance theirwelfare.
