Abstract: Under the background of China vigorously promoting the construction of open innovation ecology, how enterprises can use the Internet platform to accelerate global technology exchange and promote patents overseas has become an important content of high-quality ‘going out’ for Chinese enterprises. On the basis of clarifying the intrinsic mechanism of the influence of corporate internetisation on overseas patent applications, this paper empirically examines the influence of internetisation on corporate patents going abroad by applying the data of overseas patent applications filed by Chinese GEM listed companies from 2009 to 2021. It is found that the Internetisation of enterprises has a positive incentive effect on patent technology going overseas, which significantly increases the number of overseas patent applications by enterprises, and the conclusion still holds after a series of robustness tests. The mechanism test shows that enterprise internetisation helps its patents to go overseas by improving its collaborative innovation ability and reducing its operating costs. Further research finds that Internetisation has a more obvious effect on promoting overseas patent applications of enterprises with a higher degree of market competition and larger scale. The conclusion of this paper provides a useful reference for promoting Chinese enterprises to actively layout their patents overseas and then improve the international influence of technology.
