Abstract: Based on sample data from A-share listed heavy polluters from 2012 to 2021, this paper adopts the double-difference method to explore the influence of the construction of national pilot zone for ecological conservation on the ESG performance of heavily polluting enterprises. Following several robustness tests, this study argues that the ESG performance of heavy-polluting companies is significantly enhanced by the construction of the national pilot zone for ecological conservation. Specifically, the construction of the pilot zone enhances the ESG performance of heavy polluters by easing financing constraints. The enhancing effect of the construction of the pilot zone on the ESG performance of heavy polluters is more prominent in terms of strengthening social responsibility and optimizing governance structure. Additionally, improving heavily polluting enterprises’ ESG performance is demonstrated to effectively enhance their financial performance. The facilitating effect of the construction of the pilot zone on ESG performance is more obvious among state-owned enterprises, enterprises with high media attention, enterprises established at a late stage, and enterprises with high-quality environmental information disclosure. This study offers an empirical foundation for the government to develop policies regarding the establishment of pilot zones and for heavily polluting enterprises to enhance their ESG performance.
