Abstract: With regard to the research gap of the heterogeneous response mechanism of enterprises to institutional pressure in the process of green innovation, this paper, by employing the fsQCA method, makes an analysis of "strategic flexibility-environmental ethics" configuration mode under multiple institutional pressures, and identifies four types of green innovation path:surviving high pressure, grasping opportunities while avoiding risks, adjusting to changing circumstances, and making spontaneous transformation. The study finds that in the path of grasping opportunities while avoiding risks and the path of making spontaneous transformation, resource flexibility and coordination flexibility can respond to or even replace institutional pressure. In the path of adjusting to changing circumstances, environmental ethics can encourage enterprises to recognize standard pressure and respond to it through complementary configuration with strategic flexibility. In the green innovation path of passive survival, standard pressure can replace environmental ethics and strategic flexibility and directly promote green innovation of enterprises. By revealing the internal and mutual allocation relationships among institutional pressure, strategic flexibility and environmental ethics, this paper contributes to institutional theory and dynamic capability theory, and provides assistence for enterprises to make green innovation and for the government to make policies.
