Abstract：
People\'s dependence on technology in the digital environment has increasingly become the focus of academic and social attention. Social media, in particular, with the functions of connecting with others and maintaining interactions, has become an inseparable part of people\'s lives. Although the formation of problematic use of social media has been extensively discussed by scholars, it is mainly confined to the individual level and lacks a macro perspective from the external environment. This study draws on the perspective of institutional theory and introduces copresence as a mediating role, aiming to investigate the influence mechanism of social environmental forces on individuals\' problematic use of social media. An online survey (N = 462) was conducted to collect data and test the research model. Our data were analyzed using the structural equation modeling (SEM) approach. Results show that social environmental forces exert an impact on problematic use of social media through the sense of copresence, and only mimetic force can directly affect behavior outcomes while the other two forces can not. Besides, social environmental forces have a relationship with people\'s sense of copresence while using social media. Among them, mimetic force and normative force positively correlate with copresence while coercive force is negatively related to copresence. Furthermore, copresence is found to influence problematic use of social media positively. Practical and theoretical implications are discussed.
摘要：
数字环境下人们对技术的依赖日益成为学术界和社会关注的焦点。社交媒体,特别是,具有与他人联系和维持互动的功能，已经成为人们生活中不可分割的一部分。尽管学者们广泛讨论了社交媒体使用问题的形成，它主要局限于个人层面，缺乏外部环境的宏观视角。本研究借鉴了制度理论的视角，引入了共情作为中介作用，旨在探讨社会环境力量对个人问题使用社交媒体的影响机制。进行了在线调查（N=462）以收集数据并测试研究模型。我们的数据使用结构方程模型(SEM)方法进行了分析。结果表明，社会环境力量通过共感对社交媒体的问题使用产生影响，只有模仿力可以直接影响行为结果，而其他两种力不能。此外,社会环境力量与人们在使用社交媒体时的共感有关系。其中,模拟力和规范力与共感呈正相关，而矫顽力与共感呈负相关。此外，发现共存对社交媒体的有问题使用有积极影响。讨论了实践和理论意义。
