While employees gradually use social media for work purposes, it remains unclear how such a use influences their knowledge sharing and work efficiency. Thus, this study explores how work motivations and communication visibility afforded by social media affect employees’ knowledge sharing and work efficiency. We find that message transparency of communication visibility enhances knowledge sharing and work efficiency but weakens the impact of reputation on knowledge sharing, whereas network translucence of communication visibility increases work efficiency and strengthens the influence of social networking on knowledge sharing. Our findings add to the literature and provide guidance on how to use social media for work.

尽管员工逐渐将社交媒体用于工作目的，但仍不清楚这种使用如何影响他们的知识共享和工作效率。因此，本研究探讨了社交媒体提供的工作动机和沟通可见性如何影响员工的知识共享和工作效率。我们发现，通信可见性的消息透明性提高了知识共享和工作效率，但削弱了声誉对知识共享的影响，而通信可见性的网络透明性提高了工作效率，并增强了社交网络对知识共享的影响。我们的发现增加了文献资料，并提供了有关如何使用社交媒体进行工作的指导。
