This study examines the impact of state ownership on share price informativeness using the unique setting of the Split Share Structure Reform in China. This reform abolishes the trading restriction on shares held mainly by state shareholders. In doing so, it renders state shareholders' wealth more sensitive to share price movements and decreases their conflict of interests with private shareholders. This change is expected to strengthen the corporate governance incentives of state shareholders and reduce the information asymmetry in Chinese listed firms. This prediction is confirmed through empirical evidence of increased share price informativeness among firms that are more sensitive to the impact of this reform, i.e. those with more state ownership or restricted shares. These findings imply that this reform benefits the information environment and minority shareholders in the Chinese stock market

We find that the cost and profit efficiencies improved across all types of Chinese domestic banks in general and the banks are more profit-efficient than cost efficient. Foreign banks are the most cost efficient but the least profit efficient. The profit efficiency gap between foreign banks and domestic banks has widened after the World Trade Organization transition period (2007-2013). Ownership structure, market competition, bank size, and listing status are the main determinants of the efficiency of Chinese banks. We also find a causal relationship between efficiency and SROE by using the panel auto regression method. The evidence from the shadow return on equity (SROE) suggests that policy makers should be cautious of the adjustment costs imposed by the recapitalization process, which offsets the efficiency gains.authorsversionPeer reviewe
