ESG ratings and green innovation: A U‐shaped journey towards sustainable development
基于2011-2022年中国A股上市公司数据，发现ESG评级与绿色创新呈U型关系：低评级公司牺牲绿色创新改善治理，高评级公司则视绿色创新为增长点，且政府补贴和薪酬激励起调节作用。
Abstract This study examines the relationship between corporate ESG ratings and green innovation based on data from Chinese A‐share listed companies for the period between 2011 and 2022. The findings suggest a “U”‐ shaped relationship between ESG ratings and green innovation. Companies with lower ESG ratings (referred to as “bad” companies) tend to focus on improving their corporate governance and operational conditions, often at the expense of green innovation. However, as companies improve their ESG ratings, they increasingly view green innovation as a key growth area. This relationship is particularly evident in companies with low profitability and high operational risks. Additionally, we explore the impact of corporate ESG ratings on different types of green patents. The study finds that “bad” companies can mitigate the negative impact on green innovation through collaborative efforts, while non‐inventive green innovations, they benefit from independent research and development. Furthermore, the study examines the role of government subsidies and executive compensation in influencing this relationship. The results show that government subsidies can both positively and negatively affect green innovation, depending on the company's operational status and ESG rating. The results provide valuable insights for companies, investors, and policymakers regarding the significant role of ESG scores in promoting green innovation and suggest strategies to enhance corporate sustainability performance.
