This article investigates the relationship between the number of informational channels and overeducation
in the outcome of job search, using the survey data of postgraduates in China. The empirical
results show: (1) the more the informational channels of job search are used, the lower the probability and
the less the intensity of over-education will be; (2) graduates from prestigious “985” universities have
lower probability and less intensity of over-education than those of their counterparts from “none-985”
universities. Based on the findings above, we argue that helping graduates to get more job information and
improving the quality of universities will lighten the problem of the over-education under the situation of
great higher education expansion.
