基于媒介情境理论，通过两阶段收集的290份问卷数据，探究了企业社交媒体（ESM）沟通可见性对员工组织公民压力的影响。研究结果表明：ESM沟通可见性的信息透明和网络半透明对员工获得型和防御型印象管理行为均有正向影响，且网络半透明影响更大；防御型印象管理行为对员工组织公民压力有正向影响，且ESM沟通可见性的网络半透明通过防御型印象管理行为的完全中介正向影响员工组织公民压力。另外，员工自我监控水平在上述关系中起正向调节作用。

rounded in media situational theory, this study investigates the impact of enterprise social media (ESM) communication visibility on employees’ organizational citizenship pressure through 290 survey responses collected in two stages. The findings indicate that both message transparency and network translucence of ESM communication visibility have positive effects on employees’ acquisitive and defensive impression management behaviors, with network translucence exhibiting a stronger impact. Furthermore, defensive impression management behavior positively affects organizational citizenship pressure, and network translucence positively influences organizational citizenship stress through the full mediation of defensive impression management behavior. Additionally, employees’ self-monitoring levels play a positive moderating role in the aforementioned relationships.
