Abstract:Innovation consortium is an effective organizational form to solve the bottleneck problems. Identifying the influencing factors of knowledge co-creation in innovation consortium and realizing knowledge co-creation in innovation consortium are the keys to effectively play the role of innovation consortium. From a systemic perspective, based on the multi-agent theory model, 16 influencing factors of knowledge co-creation in innovation consortia are analyzed and refined from four aspects: subject, object, mediator, and environment. Then, the two-tuple linguistic-DEMATEL method was used to conduct an in-depth study on the causal categories and importance of each factor, to identify the cause group factors and result group factors of knowledge co-creation in the innovation consortium, and to comprehensively compare the influence degree, affected degree, cause degree, and centrality scores of each factor to identify the key influencing factors. The results show that: the knowledge co-creation of innovation consortium is jointly influenced by multiple factors; the knowledge co-creation platform is the most important causal factor; the knowledge co-creation performance is the most important result factor; the level of knowledge stock, willingness to share knowledge, knowledge co-creation performance, knowledge co-creation platform, digital technology tools, network structure, and policy system are key factors. The research results can not only deepen the research on innovation alliances and knowledge co-creation, but also provide ideas for promoting knowledge co-creation in innovation alliances. Therefore, it is necessary to effectively utilize digital tools, build knowledge co-creation platforms, and strengthen government empowerment to create favorable knowledge co-creation environment in order to improve the knowledge co-creation effect of innovation consortium.
