Abstract:
In this paper, we theoretically analyze the mediating effect of import in the relationship between intellectual property rights (IPRs) protection and innovation, and then we use firm-level data of China Industrial Enterprise Data and customs data to analyze the effect of IPRs on innovation, and we also test the mediating effect of import. Empirical results show that: (1) Stronger IPRs protection has a positive effect on innovation of leading innovative enterprises; (2)From the perspective of mechanism, stronger IPRs protection can promote innovation of private enterprises, patent-intensive enterprises and exporting enterprises by affecting import values. Stronger IPRs protection can promote innovation of private enterprises and patent-intensive enterprises by affecting diversity of import products. What's more, stronger IPRs protection can promote innovation of exporting enterprises by affecting quality of import products. China is at an important stage of implementing innovation-driven development strategy, and government should pay high attention to the promotion of intellectual property rights protection and import trade on innovation.
