The choice between further education and employment is a decision that every college graduate must face.An analysis of the income returns from graduate education can provide an important reference.This study is based on the weak screening hypothesis,and analyzes the heterogeneity of graduate education returns,examining the returns from graduate education for college graduates from general and key universities in both the early and later stages.The results show that in the early stage,graduate education mainly serves as a signal function,and graduates from regular higher educational institutions can gain more returns from graduate education.In the later stage,the human capital added by graduate education plays a major role,and graduates from key universities can gain more returns.In terms of theoretical contributions,firstly,this study has verified and advanced the weak screening hypothesis,making up for the lack of distinction between the specific situations where the human capital function and signal function of education play a role.Secondly,this study provides a unified explanation for the negative and positive selection of higher education returns using the weak screening hypothesis,supplementing the explanation of the signal function and breaking through the limitations of existing research confined to the human capital model.
