The role of institutional investors in the development of Environmental, Social, and Governance (ESG) criteria lacks consensus in the academic community. This study utilizes a quasi-natural experiment involving Chinese mutual funds that have signed the United Nations Principles for Responsible Investment (UNPRI) to investigate whether institutional Investors’ ESG investment commitments can significantly reduce ESG rating disagreement among the companies in their portfolios. We first find that companies held by ESG commitment institutional Investors exhibit less disagreement in ESG rating compared to those held by Non-ESG commitment institutional Investors. we then show that institutional Investor’ ESG investment commitment influence ESG rating disagreement by enhancing the quality of ESG disclosure and attracting external ESG attention. We further discover that institutional investors’ ESG investment commitments significantly mitigates the ESG rating disagreement among domestic ESG rating agencies and firms with a higher level of corporate governance.

In this paper, we use a distinct quasi-natural experiments to examine the effect of liberalization of the stock market on corporate environmental, social, and governance(ESG) disclosure quality. We find that the liberation of the opening of Shanghai(Shenzhen)-Hong Kong Stock Connect (SHSC) significantly and consistently improves ESG disclosure quality of listed companies, and this effect is most evident in environmental information disclosure. We then find that the SHSC can improve the quality of ESG disclosure of listed companies through “voting with feet” and “external supervision” effect. Furthermore, the effect is stronger in firms that are Non-SOEs and with low equity concentrations. Overall, our results suggest that the liberalization of stock market can improve the quality of companies’ ESG disclosure quality.
