Employing a sample consisting of Chinese A-share listed companies, this study carries out an empirical research to investigate the influence path of political connections on enterprise environmental performance. The results show a strong positive association between political connections and corporate environmental performance, and green technology innovation plays the mediating role between them. In addition, public participation negatively moderates the relationship between political connections and corporate environmental performance. When the level of public participation is higher, the relationship between political connections and corporate environmental performance becomes weaker.
