Social networks formed through social media platforms have facilitated knowledge sharing among primary health care professionals (PHCPs). However, the impact of these networks on PHCPs' job performance and the mediating role of knowledge sharing remain underexplored. This study aimed to investigate the association between social networks formed via social media and the job performance of PHCPs, and to explore the mediating role of knowledge sharing in this association.
A cross-sectional survey was carried out among PHCPs in Henan Province, China, involving 655 valid responses. Validated scales measured the key variables, and structural equation modeling (SEM) tested the proposed hypotheses, including the mediating effect of knowledge sharing through bootstrap method. Statistical analysis was performed using SPSS 24.0 and AMOS 24.0.
The degree centrality ( = 0.225; = 0.001) and network heterogeneity ( = 0.093; = 0.043) of the social network had a significant direct association with job performance, whereas the direct associations of betweenness centrality and network tie strength with job performance were not significant. Knowledge sharing mediated the relationship between degree centrality ( = 0.147; = 0.001), network heterogeneity ( = 0.251; = 0.043), and job performance.
The study revealed the internal mechanisms by which social network characteristics influence PHCPs' job performance, highlighting the mediating role of knowledge sharing. Social networks formed within social media contexts have multifaceted effects on job performance, with knowledge sharing as a critical mediating variable. These findings underscore the importance of leveraging social media for professional networking and knowledge exchange to enhance PHCPs' job performance.
通过社交媒体平台形成的社交网络促进了初级卫生保健专业人员（PHCPs）之间的知识共享。然而，这些网络对PHCPs工作绩效的影响以及知识共享的中介作用仍未得到充分探索。本研究旨在调查通过社交媒体形成的社交网络与PHCPs工作绩效之间的关联，并探讨知识共享在这种关联中的中介作用。
在中国河南省的PHCPs中进行了一项横断面调查，共获得655份有效回复。使用经过验证的量表测量关键变量，并通过结构方程模型（SEM）检验所提出的假设，包括通过Bootstrap方法检验知识共享的中介效应。使用SPSS 24.0和AMOS 24.0进行统计分析。
社交网络的度中心性（= 0.225；= 0.001）和网络异质性（= 0.093；= 0.043）与工作绩效存在显著直接关联，而中介中心性和网络联系强度与工作绩效的直接关联不显著。知识共享在度中心性（= 0.147；= 0.001）、网络异质性（= 0.251；= 0.043）和工作绩效之间的关系中起中介作用。
该研究揭示了社交网络特征影响PHCPs工作绩效的内在机制，突出了知识共享的中介作用。在社交媒体环境中形成的社交网络对工作绩效具有多方面影响，知识共享是一个关键的中介变量。这些发现强调了利用社交媒体进行专业网络建设和知识交流以提高PHCPs工作绩效的重要性。
