Analyzing data from Chinese online interactive investor platforms, our study reveals that Minority Shareholder Activism (MSA) effectively curtails informed insider trading by voting with their hands or feet, particularly in firms with weaker external monitoring. MSA not only reduces the profitability of insider trading but also encourages firms and regulators to implement stricter ex-post disciplinary measures. Moreover, MSA alleviates the negative impact of insider trading on the stock market by enhancing stock liquidity, increasing stock price informativeness, and reducing crash risk.

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.
