RESUMO
OBJECTIVE To quantitatively evaluate the existing payment policies of diagnosis-related groups （DRGs）in China ， so as to provide reference for the formulation and improvement of policies. METHODS Totally 58 documents related to DRGs payment issued by the national and provincial medical security bureaus from 2017 to 2022 were processed by text mining method. PMC index evaluation model of DRGs payment policy was established. Nine typical DRGs payment policies were quantitatively evaluated and analyzed by 10 primary variables and 40 secondary variables. RESULTS Among the 9 policies，5 were excellent and 4 were acceptable. The average score of PMC index was 6.882. Generally ，there was still room for improvement because of the acceptable level. By comparing the two representative policies ，it was found that the main reasons was a lack of consideration in terms of supervision and management ，incentives and constraints when facing policy changes ，reason of the lower level of urban development. CONCLUSIONS Although DRGs payment policy in China is basically perfect ，there is still a lot of room for improvement in terms of extending the time limit of the policy ，summarizing and spreading the successful experience of pilot cities.
