Abstract Using the provincial panel data, this paper measures regional innovation efficiency (rie) of high-tech industries, and then build dynamic spatial Dubin model to analyze the influences and spatial spillover effects of rie on international trade of high-tech industries, finally to estimate the threshold effect. It is found that: Wholly average level of rie are high with trend of convergence. The local effect of rie is higher than the diffusion effect of that. The improvement of rie can effectively enhance the enthusiasm of high-tech industries to participate in international trade. Notably, the positive influence of rie is restricted by the level of market competition. Both openness and FDI have positive influences and spillover effects, while market competition has negative effects. The rie makes a significant positive spatial spillover effect on the international trade intensity of high-tech industries. The influences and spillover effects of variables on the major four economic zones are somewhat different.
