Abstract
We examine whether China’s industry-information disclosure guidelines (IIDGs) improve firms’ stock price informativeness and the quality of their textual disclosure. Employing a stacked difference-in-differences design, we find that applicable firms respond to IIDG implementation by including additional IIDG-related and firm-specific information in the Management Discussion and Analysis (MD&A). Our results also show that the stock market reacts to the enhanced disclosure and incorporates more firm-specific (rather than market-wide or industry-level) information into the stock price, as evidenced by a decrease in stock return synchronicity. Further analyses show that firms with fewer increases in textual disclosure following IIDG implementation are more likely to receive disclosure-related comment letters. Additionally, the extent to which firms change their textual disclosure varies with the industry concentration and firms’ profit margins due to the proprietary costs of disclosure.
