According to the Information Disclosure Management Measures for Listed Companies (CSRC Order No. 40 issued on January 30, 2007), to standardize information disclosure behaviors of issuers, listed companies, and other information disclosure obligors, listed companies shall disclose relevant information promptly, accurately, and completely, including prospectuses, offering circulars, listing announcements, periodic reports, and temporary reports.
Timely and accurate corporate announcements can provide investors with negative or positive signals that impact real-time markets. Retrospective analysis of historical corporate announcements enables academic investigations into market reactions, investor sentiment, and corporate performance. In the current new media era, market responses to corporate announcements have become more immediate and intense, all of which can be quantified through big data analytics.
The A-share listed company shareholders' meeting announcement data launched by CnOpenData contains comprehensive fields including Stock code (股票代码), Company name (公司名称), Announcement title (公告标题), Announcement time (公告时间), Category (分类), Industry (行业), and Year (年度). This dataset provides robust data support for research on A-share listed companies and securities markets.
