Credit information system is a system to record the credit behavior of individuals or enterprises, which can help financial institutions evaluate the credit status of borrowers. In China, the Credit Information Center of the People's Bank of China is the main personal credit information agency, which collects and stores personal credit information, including loans, credit card repayment and other information. When financial institutions approve loan or credit card applications, they will refer to these credit information to decide whether to approve the applications. Therefore, if the borrowing behavior of a platform is recorded in the credit information system, timely repayment can improve the personal credit score, while overdue repayment may have a negative impact on personal credit.
