Why do firms appoint expired independent directors? How do expired independent directors affect corporate governance and thus impact investment decisions? By taking advantage of the sharp increase in expired independent directors’ re-employment in China caused by exogenous regulatory shocks, Rule No. 18 and Regulation 11, this paper adopts a PSM-DID design to test the impact of expired independent directors on CSR performance. We find that firms experience a significant decrease in CSR performance after re-hiring expired independent directors and the effect is stronger for CSR components mostly related to internal governance. The results of robustness tests show that the main results are robust to alternative measures of CSR performance, an extended sample period, alternative control groups, year-by-year PSM method, and a staggered DID model regarding Rule No. 18 as a staggered quasi-natural experiment. We address the endogeneity concern that chance drives our DID results by using exogenous regulatory shock, an instrumental variable (the index of regional guanxi culture), and placebo tests. We also find that the negative relation between the re-employment of expired independent directors and CSR performance is more significant for independent directors who have more relations with CEOs and raise less objection to managers’ decisions, and for firms that rely more on expired independent directors’ monitoring roles (e.g., a lower proportion of independent directors, CEO duality, high growth opportunities, and above-median FCF). The mediating-effect test shows that the re-employment of expired independent directors increases CEOs’ myopia and thus reduces CSR performance. In addition, we exclude the alternative explanation that the negative relation is caused by the protective effect brought by expired independent directors’ political backgrounds. Our study shows that managers may build reciprocal relationships with expired independent directors in the Chinese guanxi culture and gain personal interest.

We examine the effect of minority shareholder voting rights on labor investment efficiency using a sample of Chinese firms. Taking advantage of the difference-in-difference setting, our study reveals that the expansion of minority shareholder voting rights has a detrimental effect on labor investment efficiency. Through analysis of holding period and a managerial shortsightedness index based on textual analysis, we find that this outcome can be attributed to the fact that minority shareholders typically prioritize short-term gains over long-term corporate growth. Moreover, the impact of voting power is more pronounced in determining the investment efficiency of rank-andfileemployees. Our results are more significant for firms that face severe financial constraints, are non-state-owned enterprises, exhibit lower levels of internal control, possess fewer female managers, demonstrate lower human capital quality and higher labor intensity. Taken together, our paper suggests that minority shareholders could be myopia in making labor decisions.

We investigate the unintended real effects of regulator-led minority shareholder activism on corporate innovation. We use manually collected data from the China Securities Investor Services Center (CSISC), a novel regulatory investor protection institution controlled by the China Securities Regulatory Commission (CSRC) that holds 100 shares of every listed firm. We find that by exercising its shareholder rights, the CSISC substantially curtails the innovation output of targeted firms. This effect is amplified in cases involving a high level of myopic pressure and few innovation incentives. We further observe variation in the real effects of different intervention methods. Textual analysis reveals that CSISC intervention with a myopic topic and negative tone contributes to a decrease in innovation. The results of a mechanism analysis support the hypothesis that regulator-led minority shareholder activism induces managerial myopia and financial constraints, impeding corporate innovation. Furthermore, CSISC intervention not only diminishes innovation output but also undermines innovation efficiency. In summary, our findings suggest that regulator-led minority shareholder activism exacerbates managerial myopia to cater to investors and financial constraints, ultimately stifling corporate innovation.

Digital transformation empowers enterprises with new kinetic energy for high-quality development, can digital transformation enhance the transparency of capital market? This study constructs a corporate digital transformation index, and examines its impact on Chinese capital market transparency from the perspective of information senders. We find that corporate digital transformation significantly improves transparency, and this finding is more pronounced in non-SOEs, firms with low political connection, high industry environment uncertainty, and low regional marketization level. Channel tests show that lowering management myopia and increasing analyst attention are possible mechanisms. Furthermore, digital transformation improves stock liquidity by enhancing enterprises’ information transparency. Overall, our findings provide critical insights for improving transparency in China’s capital market.

From 2013 to 2015, China lifted the ban on margin trading for designated stocks based on apublic ranking index. Using a regression discontinuity design that exploits the threshold rules, I find that margin trading eligibility causes the stock share turnover and prices to increase. Moreover, firms react to this speculative pressure by manipulating earnings and reducing long-term investment. These effects are stronger for firms that are more prone to investor short-termism ex-ante. Consistent with managerial myopia, marginable firms later experience a decline in operating performance. My results suggest that margin traders, as short-term speculators, pressure the manager to focus on current earnings and take myopic actions.
