Wang J, Ma M, Dong T, et al. Do ESG ratings promote corporate green innovation? A quasi-natural experiment based on SynTao Green Finance's ESG ratings[J]. International Review of Financial Analysis, 2023, 87: 102623.

【内容摘要】Corporate efforts in green technology improvements are critical for enhancing sustainability; consequently, how to promote green innovation has attracted scholarly attention. This study explores whether and how environment, social, and governance (ESG) ratings influence corporate green innovation by using an independent third-party rating agency's (SynTao Green Finance) ESG ratings in China as a quasi-natural experiment. We find companies covered by the ESG rating agency significantly increase green innovation output by 3.9%, mainly as an increase in green invention patents. ESG ratings' positive effects on green innovation are more pronounced for firms whose investors are less short-sighted, non-state-owned enterprises and firms with higher degree of financial constraints. Additionally, we find ESG ratings' impact can also increase the green innovation quality and synergetic green innovation. Thus, ESG ratings from third-party institutions can effectively increase corporate green innovation, which has important implications for companies to achieve green transformation and for emerging markets to improve ESG rating systems.
