Abstract:Based on the sample of A-share listed companies from 2014 to 2018, this paper explores the relationship between manager power and innovation behavior, and analyzes the regulatory role of heterogeneous institutional investment between them. The results show that ownership power and expert power have a significant positive impact on innovation behavior, ownership power is more conducive to market innovation, and expert power is more conducive to technology innovation; Organization power and reputation power have significant negative effects on innovation behavior. Organization power can inhibit technology innovation, while reputation power has stronger negative effects on market innovation; Pressure-resistant institutional investors can play the role of supervision and governance, and encourage managers to produce innovative behavior by relieving managers' short-term performance pressure; Pressure-sensitive institutional investors tend to form alliances with managers, which makes it difficult for them to play an independent supervision role and does not contribute to the creation of innovation behavior.
