Knowledge sharing of family doctor teams under the county medical community is an important way of interaction between the county and rural institutions, which plays an important role in enhancing the quality of regional medical and health services and improving the health of residents.

To investigate the knowledge sharing among family doctor teams under the county medical community, to explore its influencing factors, and to provide a scientific basis for promoting knowledge management and capacity enhancement within family doctor teams.

From October to December 2022, multistage sampling was used for selecting 381 family doctor teams under two county medical communities were selected as study subjects in Hubei Province using the convenience sampling method, and a self-administered team knowledge-sharing questionnaire was used to investigate the knowledge-sharing level of the included subjects, and multivariate linear stepwise regression analyses were used to explore the influencing factors of the knowledge-sharing of family doctor teams, including two dimensions of explicit knowledge sharing and implicit knowledge sharing.

The total knowledge sharing score of family doctor teams under county medical communities was (27.84±3.84), and the mean item level scores of the two dimensions of explicit and implicit knowledge sharing were (5.51±0.79) and (5.61±0.77), respectively; the results of the multivariate linear stepwise regression analysis showed that the heterogeneity of academic qualifications, intensity of team communication, intensity of team activities, motivation of members to learn, the use of platform carriers, and the team leader's role were the influencing factors of knowledge sharing of family doctor teams under the county medical community (P<0.05) .

Knowledge sharing within the family doctor team under the county medical community is at a good level, and there is still room for improvement. It is recommended to improve the level of knowledge sharing among family doctor team members by increasing the frequency of family doctor team activities, improving the intensity of team communication, adopting relevant incentives, and expanding knowledge sharing channels.

县域医共体下家庭医生团队知识共享是县乡村三级机构之间互动的重要方式，对于提升区域医疗卫生服务质量、改善居民健康水平等起重要作用。

了解县域医共体下家庭医生团队的知识共享现状，探讨其影响因素，为促进家庭医生团队内部知识管理和能力提升提供科学依据。

于2022年10—12月，采用方便抽样法在湖北省抽取2个县域医共体，经多阶段抽样选取医共体下的381个家庭医生团队为研究对象。采用自编团队知识共享调查问卷调查团队的知识共享水平，包括显性知识共享、隐性知识共享两个维度。采用多元线性逐步回归分析探讨家庭医生团队知识共享的影响因素。

县域医共体下家庭医生团队知识共享总得分为（27.84±3.84）分，显性知识共享、隐性知识共享维度的平均条目水平得分分别为（5.51±0.79）、（5.61±0.77）分。多元线性逐步回归分析结果显示，学历异质性指数、团队长作用、团队沟通强度、平台载体使用水平、团队活动强度、成员学习积极性是县域医共体下家庭医生团队知识共享总得分的影响因素（P<0.05）。

县域医共体下家庭医生团队内部知识共享处于良好水平，但仍有提升空间。建议通过增加家庭医生团队活动频次，提高团队沟通能力，采取相关激励措施，拓展知识共享渠道等促进家庭医生团队成员知识共享。
