中文摘要：

文章基于组织支持理论和“压力源-压力-压力结果”框架,探讨了不同强度的工作边界对员工情绪耗竭的差异性影响,考察了角色压力的中介效应和边界弹性能力的调节效应。通过对企业样本数据的收集和分析,证实工作边界强度与员工的情绪耗竭之间存在U形关系;并且角色压力在这一关系中起着中介作用,即工作边界强度通过与角色压力之间的U形关系而对员工情绪耗竭产生了U形的影响;此外,边界弹性能力调节了工作边界强度与员工角色压力之间的U形关系,即较高的边界弹性能力有助于缓和工作边界强度对员工角色压力的负面影响,并且相较于过强和过弱的工作边界,这一缓和效果在适中工作边界强度条件下最好;更进一步,还发现边界弹性能力还调节了角色压力的中介效应。

英文摘要：

Based on organizational support theory and ＂stressor-strain-outcome＂ model, this study constructs a moderated mediation model to research the mechanism between workload boundary and employees＇ emotional exhaustion. Using a question- nacre survey, the results show that there is a U-shape relationship between the workload boundary and the employees＇ emotional exhaustion; and this relationship is mediated by employees＇ role stress. Furthermore, boundary flexibility moderates the U- shape relationship between workload boundary and employees＇ role stress. This means that the boundary flexibility can help reduce the negative effects of the workload boundary on the employees＇ role stress, and compared with too strong and too weak workload boundary, the reduced negative effects are the most appropriate when the workload boundary is in the middle. Lastly, workload flexibility moderates the mediation effects of employees＇ role stress.
