Abstract:Enterprises have formed enterprise value network through mutual competition and cooperation, but with the change of knowledge redundancy, there is still a lack of sufficient theoretical and practical research on how to use complementary assets to promote innovation performance. On the basis of introducing enterprise value network and knowledge redundancy as intermediary variables and regulatory variables respectively, taking 216 innovative enterprises as research samples, this paper makes an empirical study by using the methods of factor analysis and multiple linear regression to explore the impact mechanism of complementary assets on innovation performance. It is found that the more complementary assets that can be used in the value network ecology, the more stable the operation of the enterprise value network. The enhancement of the stability of enterprise value network is conducive to the improvement of innovation performance. A certain level of knowledge redundancy is conducive to promoting enterprise innovation performance. Enterprise value network plays an intermediary role between complementary assets and innovation performance. Knowledge redundancy regulates the relationship between complementary assets and innovation performance, enterprise value network and innovation performance. The research further enriches the “platform innovation theory” with complementary assets as the main content and the “knowledge-based theory” with knowledge redundancy as the main content, which has important theoretical reference and practical guiding significance for the sustainable development of enterprise value network and innovation performance.
