  To further enhance the quality of listed companies, protect the legitimate rights and interests of investors, and maintain the order of the securities market, the China Securities Regulatory Commission (CSRC) issued the Notice on Implementing the Work Plan for Promoting Random Sampling (CSRC Announcement [2015] No. 80) in accordance with policy documents including the Notice of the General Office of the State Council on Promoting Random Sampling to Regulate Mid-Event and Post-Event Supervision (Guo Ban Fa [2015] No. 58). Since 2016, CSRC has implemented on-site inspection and random sampling of listed companies, requiring various provinces and cities with independent planning status to conduct random sampling to strengthen preventive regulation.

  CnOpenData presents the A-Share Listed Companies On-site Inspection Random Sampling Dataset, which includes fields such as province and city with independent planning status (省份和计划单列市), document issuance date (发文日期), work implementation period (工作开展时间), inspection scope cutoff date (检查范围截止时间), number of listed companies in the jurisdiction (所辖区域上市公司数), and sampled company names (抽取时公司名称).
