Based on the resource advantage theory and knowledge-based theory, this study explores the impact of green entrepreneurial orientation (GEO) on green innovation, the moderating role of green absorptive capacity (GAC), and the mediating role of knowledge creation process. Through the survey of 173 middle-senior managers, this study finds that GEO significantly affects green innovation, and GEO has a positive impact on knowledge exchange (KE) and knowledge integration (KI). Furthermore, GAC strengthens the positive impact of GEO on knowledge creation process. Additionally, KE and KI have positive impacts on green product innovation and green process innovation. KE and KI play the mediating roles in the relationship between GEO and green innovation. These results expand the theoretical basis of green entrepreneurship, provide a more comprehensive understanding of how to carry out green innovation for enterprises, and contribute to the improvement of the research on green entrepreneurship.
