基于角色理论，通过收集3个阶段的253份员工数据，探究移动技术的工作使用对员工工作-家庭冲突的影响机制及边界条件。研究结果表明：移动技术的工作使用不仅与工作-家庭冲突正相关，还会通过角色超载间接激化工作-家庭冲突；组织支持可以削弱移动技术的工作使用与角色超载之间的正相关关系，同时也削弱了移动技术的工作使用通过角色超载对工作-家庭冲突的中介作用。

Based on Role Theory, the research explored the mechanism and boundary conditions of mobile technology usage for work on employees’ work-family conflict through 253 valid employee samples collected in three stages. Research results shed light on the following findings: the use of mobile technology for work could not only directly increase employees’ work-family conflict level, but also indirectly aggravate conflict level through role overload. Organizational support could weaken the positive relationship between the use of mobile technology for work and role overload. At the same time, it weakens the mediating effect of the use of mobile technology for work on work-family conflict through role overload.
