IPO (Initial Public Offing), or Initial Public Offering, refers to the first time a company (issuer) offers its shares to the public.

  The capital market serves as the core of the modern financial system and represents the most efficient financing channel and powerful capital operation platform for enterprises. As the sole pathway for companies to enter the capital market, IPO subjects companies to stricter information disclosure and corporate governance requirements. This, to some extent, reduces the risk profile of companies while maximizing corporate value and enhancing shareholder returns. The CnOpenData A-share Listed Companies IPO Inquiry Letter Text Dataset comprehensively covers various documents throughout the IPO listing process of companies in China's capital market, holding significant importance for empirical research and standardized development of China's capital market.

  This dataset collects IPO inquiry letter text data from A-share companies listed on the Shanghai Stock Exchange and Shenzhen Stock Exchange, containing fields such as Company Name (公司名称), Disclosure Type (披露类型), Listing Board (上市板块), Sponsoring Institution (推荐机构), Disclosure Time (披露时间), Announcement (公告), and URL (URL).
