　　This paper calculates educational mismatch index of different industries in China. Then it employs multi-instrumental variable method to inspect the effect of export trade on educational mismatch. It arrives at the conclusion that the improvement of export trade significantly reduces industrial educational mismatch index namely export trade is ben- eficial to the alleviation of the phenomenon that highly educated labor is engaged in low-tech jobs. Based on above-mentioned studies, this paper argues that the implementation of indus- trial opening-up policy helps to reduce the efficiency losses caused by educational mismatch and optimize the allocation of labor resources.
