Abstract: with the enrichment and improvement of green entrepreneurship theory, green entrepreneurship orientation has become an important topic in the field of green entrepreneurship research. Based on the theory of knowledge creation spiral, this paper introduces green knowledge creation and knowledge absorptive capacity as mediating variables and moderating variables, and constructs a theoretical model of the influence mechanism of green entrepreneurial orientation on green competitive advantage. Through the empirical analysis of 589 questionnaires, the results show that: Green entrepreneurial orientation has a positive impact on green competitive advantage; green knowledge creation plays an intermediary role between green entrepreneurial orientation and green competitive advantage; knowledge absorptive capacity positively moderates not only the relationship between green entrepreneurial orientation and green competitive advantage, but also the relationship between green knowledge creation and green competitive advantage; knowledge absorption capability positively moderates the process of green entrepreneurial orientation influencing green competitive advantage through green knowledge creation. The results of this research are helpful to enrich and expand green entrepreneurship theory and provide guidance for green entrepreneurship practice.
