企业通过相互竞合关系形成了企业价值网络，但随着知识冗余的变化，企业如何运用互补性资产促进创新绩效仍缺乏充足的理论与实践研究。在分别引入企业价值网络和知识冗余作为中介变量和调节变量的基础上，以216家创新型企业为研究样本，运用因子分析以及多元线性回归等方法进行实证研究，探讨互补性资产对创新绩效的影响机理。研究发现：价值网络生态中可以利用的互补性资产越丰富，企业价值网络的运行越稳定；企业价值网络稳定性的增强有利于创新绩效的提升；一定水平的知识冗余有利于促进企业创新绩效；企业价值网络在互补性资产与创新绩效之间起中介作用；知识冗余调节了互补性资产与创新绩效、企业价值网络与创新绩效之间的关系。研究进一步丰富了以互补性资产为主要内容的“平台创新理论”以及以知识冗余为主要内容的“知识基础理论”，对企业价值网络与创新绩效的可持续发展具有重要的理论参考和实践指导意义。

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.
