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

  Capital markets are the core of the modern financial system, serving as the most efficient financing channel and powerful capital operation platform for enterprises. As the exclusive pathway for companies to enter capital markets, IPO subjects companies to stricter information disclosure and corporate governance requirements. This effectively reduces corporate risk coefficients while maximizing corporate value and enhancing shareholder returns. CnOpenData's IPO Issuance Text Data of A-Share Listed Companies comprehensively covers various documents throughout the IPO listing process of companies in China's capital markets, holding significant importance for empirical research and standardized development of China's capital markets.

  This dataset collects IPO issuance text data from A-share companies listed on the Shanghai and Shenzhen Stock Exchanges, with two distinct sources each for Shanghai and Shenzhen markets. It contains fields such as: Code(代码), Company Name(公司名称), Title(标题), Announcement Date(公告时间), URL(URL), Category(分类), Board(板块), Industry(行业), and Year(年度).
