Corporate ESG(Environmental,Social,and Governance)performance is a crucial criterion for eval-uating green and sustainable development.With increasing external pressure on enterprises to adopt sustainable de-velopment practices,exploring the relationship between supply chain digitization and corporate ESG performance from the perspective of institutional pressure holds significant importance.Using A-share listed companies from 2013 to 2021 as the research sample,this study examines the impact of supply chain digitization on ESG perform-ance and enriches the indicators of coercive,mimetic,and normative isomorphic institutional pressures based on in-stitutional theory,analyzing the roles these pressures play in this relationship.The findings indicate that supply chain digitization significantly enhances corporate ESG performance,a conclusion that remains robust after a series of tests.Mechanism analysis reveals that both coercive and mimetic isomorphic institutional pressures positively moderate the effect of supply chain digitization on improving ESG performance,whereas the moderating effect of normative isomorphic institutional pressure is not significant.Against the backdrop of accelerating the construction of a digital China,this research provides empirical insights from the perspective of multidimensional institutional pressure to promote the coordinated development of digital supply chain expansion and corporate sustainable devel-opment.
