A-share listed companies from 2010 to 2022 as a sample was used to investigate the spillover effect of ESG (environment、social and governance) on supply chain in the context of supply chain integration. The results showed that the ESG levels of suppliers and customers could improve the ESG levels of enterprises. The ESG spillover effect mainly occured through three channels: management knowledge resources, capital resources and technology resources sharing. For non-state-owned enterprises and regional enterprises with a higher degree of marketization, the spillover effect of ESG was more obvious. This study has important reference value for implementing strategic decision to maintain supply chain security in China, and is significant for promoting the high-quality development of listed companies.
