As an emerging enterprise reporting system, ESG plays an indispensable governance role in the economic market. Taking China's A-share listed companies from 2009 to 2022 as research samples, the role of ESG disclosure on corporate violations through empirical analysis was revealed, and further the heterogeneity of competition in different industries and media supervision was examined. The results show that ESG disclosure has an inhibitory effect on corporate violations. For companies with a higher degree of industry competition and stronger media supervision, ESG disclosure plays a stronger role in corporate violations.
