In order to comprehensively analyze the characteristics and contents of the policy release of health care payment reform in China and propose policy suggestions for future deepening reform，this study obtained 171 health care payment reform policy at the national level in China from 2009 to 2021 through systematic retrieval. Using statistical methods，social network analysis methods and content analysis methods, we constructed a three - dimensional analysis framework based on“policy tools - policy objectives - policy strength” based on the diachronic analysis of policy items and the analysis of publishing institutions. We then further conduct a multi - dimensional quantitative classification and cross - comparative analysis of policy content. The study found that policy tools are rich and diverse under the framework of policy analysis, while the internal distribution is uneven. The reform focuses on service quality improvement，but the distribution of each objective varies greatly. Additionally, the number of high - intensity specialized documents is relatively small, and the overall control capacity is low. The analysis of each cross - dimension shows different degrees of mismatch and structural imbalance. We recommend improving the internal structure of the policy and enhancing the balance of the use of policy tools；giving full play to the policy goal-strength synergy effect and improving the compatibility of all aspects of reform. It is also crucial to break the institutional factors that restrict the improvement of the policy system to promote reform and development from the bottom.
