Abstract:Open innovation is becoming a key driving force for economic development, providing an excellent ecological environment for the research and development, sharing and transfer of the results of innovation subjects, which has also caused academic discussions on the relationship between open innovation and innovation performance. Most of the existing research focuses on the internal cooperation relationship of the innovation subject, ignoring the impact of external organizational management factors (such as incentive systems) brought by the multi-level representation of open innovation on innovation performance. In this paper, 85 national cultural and technological integration demonstration bases are used as the research object, and the regression model is used to explore the direct impact of open innovation on base innovation performance and the moderating effect of government funding and policy support. The research results show that: open innovation has a significant positive impact on base innovation performance, financial support can promote the role of open innovation to improve innovation results, and the adjustment effect of policy support does not exist. Based on the reality of the application of the open innovation model of the national cultural and technological integration demonstration base, it is recommended that each base take advantage of macro-control to improve the matching degree of demand-side and supply-side technology transactions. Government departments should set a reasonable range of government funding subsidies. Improve the pertinence of policy support, and provide strategic choices and relevant practical guidance for market entities to build an open innovation ecosystem.
