社交媒体介入工作领域后衍生出“随时在线、全天候工作”的职业文化，加剧工作 与生活界限的模糊与冲突，最终导致员工的疲倦。基于媒体从业者固有的时间性结构， 本研究从社交媒体介入工作场所的“赋能-奴役悖论”切入，建构媒体从业者非工作时 间社交媒体使用引致工作倦怠模型，旨在探究媒体人在非工作时间使用社交媒体的前因 后果。基于478位媒体从业者的调查数据显示，工作需求、印象管理两种动机会显著正向 预测媒体人的非工作时间社交媒体使用；非工作时间社交媒体使用会直接影响媒体从业 者的情绪衰竭；非工作时间社交媒体使用频率会通过影响媒体从业人员的感知侵入和感 知监视，间接导致不同维度的工作倦怠情况。本研究为理解媒体从业者“浸入”在社交 媒体中的劳动状况，提供了有价值的理论依据。

During non-work times, work information is increasingly intruding into employees’ private lives and breaking work-life boundaries. Based on the research paradigm of empowerment/ enslavement paradox, this study constructs a model of social media use during non-working hours about media practitioners. In this study, 478 valid samples were collected by questionnaire survey. The results show that job demand and impression management positively predict workrelated social media use during non-work time of media practitioners. Moreover, work-related social media use during non-work time of media practitioners signifcantly positively predicts emotional exhaustion. Furthermore, the frequency of social media usage indirectly predicts the different dimensions of job burnout through invaded perception and monitored perception. The study provides a valuable theoretical basis for understanding the labor conditions of media practitioners‘immersed’in social media.
