  IPO (Initial Public Offering), referring to a company's (issuer) first sale of its shares to the public, represents the primary channel for enterprises to access capital markets.

  As the core of modern financial systems, capital markets serve as the most efficient financing channel and powerful capital operation platform for enterprises. The IPO process, being the exclusive pathway for companies to enter capital markets, enables companies to face more stringent information disclosure and corporate governance requirements. This effectively reduces corporate risk coefficients while maximizing corporate value and enhancing shareholder returns. The CnOpenData A-share Listed Companies IPO Pre-disclosure Text Dataset comprehensively covers various documents from China's capital market IPO processes, holding significant implications for empirical research and regulatory development in Chinese capital markets.

  This dataset collects pre-disclosure documents of A-share companies listed on the Shanghai and Shenzhen Stock Exchanges, containing fields such as Company Name (公司名称), Disclosure Type (披露类型), Listing Board (上市板块), Recommendation Institution (推荐机构), Disclosure Time (披露时间), Announcement (公告), and URL.
