According to the "Administrative Measures for Information Disclosure of Listed Companies", listed companies, as information disclosure obligors, shall truthfully, accurately, timely, and completely disclose information to the market in accordance with the law and voluntarily. Such publicly disclosed information includes but is not limited to basic company information, major accounting data and financial indicators, shareholder holdings, and executive compensation. Information disclosure by listed companies serves as a crucial basis for government supervision and investor behavior. Effective administrative regulation combined with market oversight forms a dual-track mechanism that promotes stable and orderly development of the securities market.
