Although the enterprises green innovation behavior has received widespread attention, a systematic analysis framework has not yet been formed. Based on the stakeholder theory, upper echelons theory and institutional theory, the article takes 211 transportation enterprises as the research object, and constructs a theoretical model between suppliers’ green pressure, top managers’ environmental awareness, government environmental regulations, and enterprises green innovation behavior. Using hierarchical regression analysis and Bootstrap method to test, it explores the impact of suppliers’ green pressure on enterprises green innovation behavior, and further analyzes the mediating role of top managers’ environmental awareness and the moderating role of government environmental regulations. The results show that suppliers’ green process collaboration and suppliers’ green knowledge sharing have a significant positive impact on the enterprises green innovation behavior; top managers’ environmental awareness plays a partially mediating role between suppliers’ green process collaboration, suppliers’ green knowledge sharing and enterprises green innovation behavior; the government environmental regulations positively moderate the relationship between suppliers’ green process collaboration, suppliers’ green knowledge sharing and enterprises green innovation behavior. Finally, it puts forward the management enlightenment to promote the green development of transportation enterprises.
