In China, the work of contracted family doctor services and its supporting policies have been emphasized. However, research findings on the evolution and trends of the theme of contracted family doctor services are relatively scarce, which is not conducive to understanding its overall development trend.

To review and analyze the evolution path contracted family doctor services policy at the central level in China, reveal the key issues and hot areas in policy formulation and implementation, and provide references for the subsequent policy optimization.

This study employed the dynamic topic model (DTM) to extract and analyzed 40 central-level contracted family doctor services policy documents from December 2008 to May 2023 and calculates their topic popularity, similarity and topic evolution path.

The DTM identified 21 policy topics and their distribution acrossed different stages. The study revealed that the policies had distinct phased characteristics, with the focus shifting from improving primary care quality to tiered diagnosis and treatment, and optimizing service outcomes. However, implementation, guidance, and standard-related policies were relatively lacking.

Policy makers should deepen the collaborative governance of contracted family doctor services policy, strengthen the stage continuity of contracted family doctor services policy, and enhance the national standards, norms, and overall guidance for contracted family doctor services.

我国重视家庭医生签约服务工作及配套政策，但针对家庭医生签约服务主题的演进与趋势研究成果相对匮乏，不便于了解其整体发展态势。

了解我国中央层面家庭医生签约服务政策的演进路径，揭示政策制定和实施中的关键问题和热点领域，为后续政策优化提供参考。

本研究采用动态主题模型（DTM）对2009年12月—2023年5月发布的40份中央层面的家庭医生签约服务相关政策文本数据进行主题提取和分析，计算其主题热度、相似度及主题演化路径。

DTM共挖掘出21个家庭医生签约服务政策主题，以及各阶段的主题热点分布。研究发现，我国中央层面家庭医生签约服务政策的阶段化属性明显，不同阶段的关注焦点从提升基层服务质量转向分级诊疗和优化服务效果，执行指导及标准类的政策相对不足。

政策制定者应深化家庭医生签约服务政策的协同治理，强化家庭医生签约服务政策的阶段承接性，并提升中央层面对家庭医生签约服务的标准规范和整体指导。
