Abstract:In this paper, patent introduction is divided into exclusive introduction and non-exclusive introduction, based on the perspective of technology catch-up theory, the influence of different introduction modes on the independent innovation performance of enterprises is compared, and the mediating effect of the knowledge base of introduced enterprises and the regulating effect of the characteristics of introduced patent knowledge are verified.The patent data of high-tech enterprises listed in Shanghai and Shenzhen from 2006 to 2019 were used for empirical test.The results show that: the patent introduction has an inverted U-shaped effect on the independent innovation performance of enterprises, and the exclusive patent introduction has a greater influence on the improvement of the independent innovation performance than the non-exclusive patent introduction, in which the knowledge base of enterprises plays an intermediary role.At the same time, When the knowledge base of the enterprise is weak, the heterogeneity of patent introduction plays a positive regulating role between non-exclusive patent introduction and enterprise independent innovation performance.
