Interest in firms’ ESG performance is longstanding and growing. However, understanding remains fragmented across firms at different stages of their life cycle. This study investigates the role of life cycle stages in the relationship between ESG and firm performance in the Chinese context. Using a sample of 26,412 firm–year observations of firms listed in China from 2011 to 2021, the results provide evidence that, although ESG has a significant positive effect on firm performance, the effect is contingent on the stages of the firm’s life cycle. The association between ESG and firm performance is more pronounced for firms in the growth and mature phases. We also find that this effect is enhanced for state-owned growth firms localized in regions with a lower marketization degree. Furthermore, the findings also extend the distinct mediation roles of institutional investors and the agency cost of free cash flow in the nexus of ESG and firm performance. This paper provides direct empirical evidence for a better understanding of firm’s behavior across different life cycle stages, as well as helps to achieve a win–win situation of firm performance and social value.

Under the background of sustainable development and high-quality development in China, it is of great significance to actively promote enterprises to practice ESG development concepts and digital transformation. This study uses a sample of state-owned companies in the Chinese capital market during the period from 2014 to 2020. The results of the research show that there is a U-shaped relationship between ESG performance and the value of state-owned enterprises. And digital transformation plays a positive moderating role in the relationship. The result of a further mechanism study indicates that ESG performance affects enterprise value by reducing the financing constraints. This study also examines the results using a dynamic panel model and endogeneity test method. Therefore, this study provides references to promote ESG practices and offers new insight into the role of digital transformation in state-owned companies. In order to pursue sustainable development and high-quality economic development, ESG practices and digital transformation should also be paid attention to in enterprises.
