Sustainable development has emerged as a global imperative, with the rapid adoption of the Environmental, Social, and Governance (ESG) framework reflecting this trend. In the context of digital transformation, this study aims to investigate the impact of ESG performance on corporate value, while also examining the moderating and mediating roles of digital transformation and green innovation within this relationship. Utilizing annual data from A-share listed companies on the Shanghai Stock Exchange (SSE) and Shenzhen Stock Exchange (SZSE) spanning the years 2018 to 2022, this research encompasses a total of 17,940 observations. Given China’s commitment to sustainable, high-quality development, this study underscores the critical importance of advancing ESG principles alongside corporate digital transformation. Empirical analysis reveals that ESG performance significantly enhances firm value, with digital transformation serving as a positive moderator that amplifies the impact of ESG performance on firm value primarily through the enhancement of firms’ green technology innovation capabilities. These findings contribute to a deeper understanding of the interaction between ESG initiatives and firm value, particularly amidst ongoing digital advancements. Consequently, this paper recommends that governments enhance corporate ESG performance through a combination of incentive and penalty mechanisms, establish a comprehensive ESG rating system, and optimize the policy framework for digital transformation. Moreover, enterprises should foster awareness of green innovation, refine their governance structures, accelerate digital transformation efforts, and promote the application of digital technologies and information sharing across various domains to achieve sustainable development and enhance competitiveness.
