Using data for manufacturing firms listed on China A‐share markets between 2003 and 2018, this research explores the impact of institutional investors on corporate green innovation. The study finds that pressure‐resistant institutional investors (PR investors) positively contribute to green innovation, whereas pressure‐sensitive institutional investors (PS investors) hinder it. In addition, this study examines the moderating effect of political ties, distinguishing between ascribed and achieved ties. Ascribed ties weaken the positive relationship between PR investors and green innovation, whereas achieved ties strengthen it and weaken the negative association between PS investors and green innovation. Moreover, the study investigates the influence of institutional development on the relationship between institutional investors and green innovation, and finds that managerial myopia is the mechanism through which institutional investors influence green innovation. Furthermore, this study reveals that there are heterogeneity effects among small and large firms, polluting and non‐polluting firms, and firms facing different levels of market competition. Overall, the study sheds new light on how institutional investors, acting as ‘invisible hands’, interact with political ties, acting as ‘visible hands’, to impact green innovation in transition economies.
