In this paper, we employ 2010, 2014 and 2016 China Family Panel Studies (CFPS) survey data to study the influence of parents' education on their children's education from the perspective of educational expectations. We study the intergenerational transmission of education from the perspective that parents' educational level will affect their perception and willingness to invest in their children’s education, thus affecting their children's educational expectations and the educational level of their offspring. To conduct our study, we use parents’ willingness of sending their children study abroad as dependent variable to measure parents’ educational expectation. Our researches are based on a series of OLS, Probit and IV estimations, the results show that there is a positive and significant relationship between parents’ education and their expectations for children's education. The higher the educational level of parents, the stronger their willingness to send their children abroad to study. The higher the educational level of parents, the higher their expectations for their children's education. Parents' expectations for their children's education affect the ways of taking education and thus have an impact on their children's final education. At the same time, we find that although both of father’s education and mother’s education will affect their expectations for their children, the gender differences between father and mother do exist. Compared with father, mother has a greater impact on children's future education.
