Policies serve as a vital driving force in advancing reforms in depth. To explore the development characteristics of policies related to the reform of DRG/DIP payment methods, this paper adopts the methods of bibliometrics, content analysis, and social network analysis to construct a six-dimensional analytical framework of "number of publications, publication forms, publication authority, policy intensity, targets, and policy tools." Through this framework, a quantitative analysis of relevant policies concerning the reform of DRG/DIP payment methods in China is conducted. The findings reveal that the number of policies follows a trend of "increase-decrease" over time, which reflects the process from pilot, promotion, to optimization and adjustment. The publication forms are relatively low-level and lack authority. The overall effectiveness demonstrates a trend of "increase-sudden decrease," with a relatively low average effectiveness, which is consistent with the encouragement of extensive exploration at the local level in the initial stage. The targets are diverse, with a focus on reform implementation plans, and the use of policy tools is comprehensive but imbalanced. Based on the analysis above, it is proposed to enhance policy effectiveness and execution from top-level design, optimize the structure of the targets to stimulate synergies effect, adjust and increase the use of demand-oriented policy tools, thereby promoting cooperation among multiple stakeholders and strengthening policy synergy to strengthen the reform of DRG/DIP payment methods.
