Credit supervision is a new type of governance means that combines the moral value of honesty and trust with legal principles，and institutionalizes and legalizes the value of honesty. Three secondary indicators are set up under the first-level indicator of “credit regulation”，which are “credit repair”，“credit rewards and punishments” and “credit disciplinary relief mechanism”. Under the second-level indicator “credit repair”，there is a third-level indicator “whether to set up guidelines for the credit repair process”；under the second-level indicator “credit rewards and punishments”，there is a third-level indicator “whether to set up a reasonable credit reward and punishment mechanism”. Under “Credit rewards and punishments”，there is a tertiary indicator of “whether a reasonable credit reward and punishment mechanism is set up”；and under “Credit punishment and relief mechanism”，there is a tertiary indicator of “whether a credit punishment and relief mechanism is set up”. After evaluation，all cities have formulated guidelines for the credit repair process，set up a relatively uniform credit reward and punishment mechanism，and basically established a credit discipline and relief mechanism. However，the following problems still exist：the lack of effective incentives for credit repair；the absence of legislative norms for credit disciplinary mechanisms and the generalization and abuse of credit disciplinary mechanisms；the narrow channels of relief in credit disciplinary relief mechanisms，and unclear legislative norms for credit relief. In the future，the positive incentive mechanism for credit repair should be improved and the credit repair system should be publicized；the legislation of credit disciplinary mechanism should be explored；and the relief mechanism for credit discipline should be constructed at the legislative，law enforcement and judicial levels.
