Abstract：Objective To analyze the impact of medical insurance payment method reform on the efficiency of health services in China and provide empirical evidence for optimizing payment policies.Methods Using panel data from 31 Chinese provinces from 2012 to 2022,it measured health service efficiency with super-efficiency SBM model,assessed the effects of payment reforms using a staggered DID model,and analyzed the heterogeneous impacts of health informatization levels and health resources.Results DRG payment method reform increased health service efficiency,while no evidence was found that DIP payment method reform improved efficiency.Heterogeneity analysis showed that DRG payment method reform effects were not significantly influenced by health informatization levels or bed resource distribution,where as DIP payment method reform's negative effects were positively moderated in regions with higher informatization or abundant bed resources.Conclusion DRG payment method reform can improve the efficiency of healthcare services.It is recommended to accelerate the promotion of the DRG payment method system.Regarding the reform of the DIP payment system,it is recommended to improve the DIP scoring settlement mechanism,strengthen refined disease management,optimize hospital information system construction,enhance the medical insurance information platform and medical record quality control system,in order to improve hospital management levels and service efficiency.
