Recent reform in China has made a subset of Chinese stocks available to foreign investors, partially opening up China's stock market. Our difference-in-differences analysis shows that this liberalization reform boosts investments in investable firms relative to noninvestable ones, with results robust to various sensitivity analyses. Besides capital inflows and risk sharing, a potential but underexplored channel is improved corporate governance due to direct and indirect pressures from foreign investors, which lowers the cost of capital and improves capital allocation efficiency. Consistent with this corporate governance channel, we find that the liberalization reform reduces investable firms’ agency costs, increases their investment efficiency and total factor productivity, and improves their operating performance. Further analysis finds that the positive investment effect from the liberalization reform is stronger among firms that were poorly governed before the reform.

During the 2015 stock market crisis, the Chinese government used hundreds of billions of dollars to purchase shares directly in the secondary market. We find that compared with non-rescued firms, rescued firms have significantly lower liquidity after being rescued. Policy uncertainty regarding subsequent interventions better explains the reduction in liquidity than the liquidity dry-up and bad firm signaling hypotheses. Inconsistent with the potential moral hazards associated with government bailouts, the investment policies of rescued firms become more conservative after being rescued. Our evidence warns of the unintended consequences of direct purchase rescue programs.
