Improving job-worker matching is a way of significance to increase market efficiency. The main purpose of this paper is to find out variations of the factors that affect job-worker matching under different marketization levels. Using multi-level random effects model we found out both tertiary degree and social network are capable to send signals of human capital, in order to improve job-worker matching. At the meanwhile, the effects vary while deepening of employment marketization. As a formal signaling mechanism, tertiary degree has a stable effect while screening method has a fading effect as an informal signaling mechanism.
