  Bonds are negotiable securities issued by governments, enterprises, banks, or other debtors to raise funds through legal procedures, promising repayment of principal and interest to creditors on specified dates. The relationship between bond purchasers (investors) and issuers is a creditor-debtor relationship, where the issuer acts as the debtor, and the investor (bondholder) serves as the creditor. Based on the issuer type, bonds in the issuance market can be categorized into government bonds, financial bonds, and corporate (enterprise) bonds. As debt instruments, bonds, like other securities, represent fictitious capital rather than real capital; they are certificates of real capital utilized in economic operations.

  In recent years, China's bond market has developed rapidly, playing a significant role in serving the economy, increasing the proportion of financing, and supporting supply-side structural reforms. According to the Statistical Yearbook of the People's Bank of China, the scale of China's bond market has steadily expanded, with total issuance continuously growing. In 2021, the total bond issuance in China reached 61.38 trillion yuan.

  Research on the bond market is crucial for constructing a new bond market framework. To this end, CnOpenData has launched the China Bond Issuance Information Data, which includes the following datasets: Bond Basic Information Table, Bond Classification Table, Bond Issuance and Offering Details Table, Bond Embedded Option Features Table, Bond Credit Rating Table, and Institutional Investment Restriction Table. These datasets provide a foundational resource for studying capital market issues.
