  According to the Administrative Measures for Information Disclosure of Listed Companies, listed companies as information disclosure obligors should truthfully, accurately, timely, and completely disclose legally required and voluntary information to the market. This publicly disclosed information includes but is not limited to: basic company information, key accounting data and financial indicators, shareholder equity structures, and executive compensation details. The information disclosure from listed companies serves as crucial evidence for government regulation and investor decision-making, combining effective administrative supervision with market oversight to form a dual-track effect that promotes stable and orderly development of the securities market.

  CnOpenData has launched A-Share listed companies' main business details data, comprising three core datasets: Business Review Table of Listed Companies, Main Business Introduction Table of Listed Companies, and Main Business Composition Table of Listed Companies.
