In recent years, Chinese college graduates have faced a challenging employment situation, calling for an analysis of the social stratification function of higher education. This paper used linear regression to analyze factors influencing the occupational status attainment of college graduates. The social stratification function of higher education was found to be significant. Educational factors were essential for occupational status attainment. Nevertheless, new graduates' occupational status could also be affected by individual and family factors. On the whole, college graduates achieved stratum promotion. Men had higher occupational status and longer mobility distance than women, and rural graduates had higher occupational status and longer mobility distance than urban graduates.
