  Openness and transparency constitute fundamental principles in government procurement management systems. Enhancing information disclosure in government procurement is not only essential for deepening comprehensive reforms and establishing modern fiscal institutions but also serves as a critical measure to strengthen public oversight and improve governmental credibility. It holds significant importance in standardizing procurement practices and upholding fairness, impartiality, and transparency in government procurement activities. Regulatory frameworks such as the Budget Law of the People's Republic of China, the Implementation Regulations of the Government Procurement Law of the People's Republic of China, and the Regulations on Practicing Frugality and Combating Waste by Party and Government Agencies establish new requirements for increasing procurement transparency, advancing information disclosure, and enhancing societal supervision across multiple dimensions. These regulations further delineate the objective of achieving full-process information transparency in government procurement.

  The scope and responsible entities for information disclosure are as follows:

  • Procurement project information, including procurement announcements, procurement documents, budget amounts, and procurement results, shall be disclosed by procuring entities or their authorized procurement agencies;
  • Regulatory and penalty information, encompassing complaint resolutions, inspection rulings, performance evaluations of centralized procurement agencies, and records of illegal or dishonest activities, shall be disclosed by financial departments;
  • Other government procurement information mandated by laws, regulations, or rules shall be disclosed by relevant entities in accordance with legal provisions.

  Procuring entities may legally select appropriate procurement methods based on project characteristics: (1) Open Tendering; (2) Selective Tendering; (3) Competitive Negotiation; (4) Competitive Consultation; (5) Inquiry-Based Procurement; (6) Single-Source Procurement; (7) Framework Agreement Procurement. Projects exceeding open tendering thresholds must adopt open tendering procedures. Alternative methods may be employed under special circumstances, subject to prior approval from同级政府采购监督管理部门 (same-level government procurement regulatory authorities) before procurement commencement.

  Currently, the CnOpenData team has released Government Procurement Data, primarily documenting bid-winning results. However, existing datasets inadequately reflect the procedural aspects of government procurement workflows. To address this gap, CnOpenData introduces the Government Procurement Announcement Data, which comprehensively details公告流程信息 (announcement process information) throughout procurement cycles. This dataset encompasses seven core components: Basic Information Tables, Prequalification Announcements, Bid-Winning Notices, Transaction Announcements, Bid Abolition/Termination Notices, Correction Announcements, and Method-Specific Notices (e.g., Open Tendering, Selective Tendering), featuring critical fields such as Title, Procuring Entity (采购人), Project Name (采购项目名称), and Category (类别). This resource aims to provide high-quality data support for related academic research.
