Abstract: Ethical leadership is a leadership style that emphasizes ethics, which plays an important role in shaping and promoting employees’ organizational citizenship behavior. Based on social learning theory and SOR (Stimulus Organism Response) model theory, the mechanism and boundary conditions of ethical leadership on employees’ green behavior are discussed. Through the empirical analysis of 310 questionnaires, a moderated mediation model is constructed. The results show that ethical leadership is helpful to the production of employees’ green behavior; The green psychological climate partially mediates the positive influence of ethical leadership on employees’ green behavior; Perceptions of insider status play a positive role in the process of green psychological climate affecting employees’ green behavior. Based on these, leaders should strengthen their own environmental morality, supervise and guide employees’ green behavior, enhance employees’ green psychological climate, deepen employees’ perceptions of insider status, and further make employees show more positive green behaviors to improve the green performance of enterprises.

Key words: ethical leadership, employees’ green behavior, green psychological climate, perceptions of insider status
