“…Moreover, the Sino-Securities ESG rating covers all A-share listed companies, covering three primary indicators (environmental, social, and corporate governance), 14 secondary indicators (environmental management systems, green business objectives, green products, external environmental certifications, environmental violations, institutional systems, health and safety, social contributions, quality management, system-building, governance structure, operational activities, operational risks, and external sanctions), 26 tertiary indicators, and over 130 underlying data indicators, resulting in a nine-grade rating from low to high (denoted as C-AAA). The indicators selected by the Sino-Securities ESG rating combine the mainstream international ESG assessment framework, consider Chinese characteristics and specific practical experience, and incorporate the opinions of external market experts, which are reasonable and have been widely used by academics [58,[72][73][74][75]. Therefore, this study draws on Fang and Hu and He and Zhuang [76,77], the C-AAA ratings are assigned as 1-9, and ESG performance is measured by taking the mean of each quarterly rating.…”
