In order to comprehensively analyze the characteristics and contents of the policy release of medical insurance payment reform in China, and put forward policy suggestions for deepening reform in the future, this study obtained 171 medical insurance payment reform policy texts at the national level in China from 2009 to 2021 through systematic retrieval. Using statistical methods, social network analysis methods, content analysis methods, based on the diachronic analysis of policy items and the analysis of publishing institutions, a three-dimensional analysis framework based on ' policy tools-policy objectives-policy strength ' was constructed, and further multi-dimensional quantitative classification and cross-comparative analysis of policy content were carried out. The study found that under the framework of policy analysis, policy tools are rich and diverse, but the internal distribution is not balanced ; the reform focuses on the improvement of service quality, but the distribution of objectives varies greatly. a small number of high-intensity special documents, the overall control capacity is low ; each cross-dimension analysis shows different degrees of mismatch and structural imbalance. It is recommended to improve the internal structure of the policy and enhance the balance of the use of policy tools ; give full play to the policy goal-strength synergy effect and improve the compatibility of all aspects of reform needs ; break the institutional factors that restrict the improvement of the policy system and fundamentally promote reform and development.
