A股上市公司招股说明书公告数据

根据2007年1月30日证监会令第40号公布的《上市公司信息披露管理办法》，为规范发行人、上市公司及其他信息披露义务人的信息披露行为，上市公司应当及时、准确、完整地披露相关信息，包括招股说明书、募集说明书、上市公告书、定期报告和临时报告等。  一份及时、准确的上市公司公告足以给投资者利空或利好的信号、影响实时市场，而回溯历年上市公司公告，又能够实现学术研究中的按图索骥——市场反应、投资者情绪、公司业绩……在当下新媒体时代，上市公司公告的市场反应则更为强烈迅速，而这些都能够通过大数据来体现。

Pursuant to the Administrative Measures for Information Disclosure of Listed Companies issued via Order No. 40 of the China Securities Regulatory Commission (CSRC) on January 30, 2007, to standardize the information disclosure practices of issuers, listed companies and other information disclosure obligors, listed companies are required to disclose relevant information timely, accurately and completely, including prospectuses, fundraising prospectuses, listing announcements, periodic reports and temporary reports, etc. A timely and accurate listed company announcement can sufficiently deliver bearish or bullish signals to investors and exert impacts on the real-time market. Retrospecting on historical listed company announcements also facilitates targeted academic research covering topics such as market reactions, investor sentiment, corporate performance and more. In the current new media era, the market response to listed company announcements is more rapid and pronounced, and all these phenomena can be captured and reflected through big data.
