The microfoundations of open innovation: CEO overconfidence and innovation choices

How to successfully drive open innovation (OI) has been an important issue. However, the existing literature on the determinants of OI mainly focuses on organizational and contingent factors, and the “human side” of it is still not well understood, which also motivates us to explore it more deeply. This paper attempts to link upper echelon theory with OI research using data from a large sample of Chinese listed companies to investigate how the overconfident tendency of the CEO affects his or her preference for different OI modes. At the same time, what role do other top management team (TMT) members play in this process. The results show that overconfident CEOs favor market and organization-oriented OI over technology-oriented OI, and TMT governance can moderate such relationship, that is, as the level of TMT governance increases, the preference of overconfident CEOs for market and organization-oriented OI will be weakened, avoiding the negative effect of excessive adoption of such activities on firm performance. By focusing on the human side of OI, this paper adds to the literature on the impact of strategic leadership, namely the influence of key individual CEO and other executives within the organization on OI management, which is also a response to the emphasis that more attention should be paid to the microfoundations of OI in the future.
