中文摘要：

以企事业单位的中基层管理人员的270份问卷为样本，采用多元回归对领导-部属交换对员工工作压力的影响及其中介机制进行分析研究。研究结果表明，领导-部属交换与员工工作压力为U型相关，与员工的领导支持感、工作满意度均为直线相关关系；领导支持感在领导-部属交换与工作满意度中起部分中介作用；工作满意度与员工工作压力为U型相关。研究结果为领导-部属交换负面效应的研究提供了中国情境下的经验验证，有助于把握领导-部属交换与员工工作压力的负面效应的作用方式和途径，使领导者意识到在实践中要关注“圈内人”身心健康，提高“圈外人”的领导-部属质量以降低员工的工作压力。

英文摘要：

With the data of the 270 questionnaires from the middle managers and employees in the organizations, this study examines the relationship between the LMX and the work stress with the methodology of hierarchical regression analysis. The findings indicate that the curvilinear effect be- tween the LMX and work stress and the linear effects among the LMX, perceived supervisor support and job satisfaction have been found. Moreover, partial mediation effect of perceived supervisor sup- port between the LMX and job satisfaction has been examined, and the curvilinear effect between the job satisfaction and work stress has been supported. These results help the researchers to open the door of the negative effects of LMX and their mediation mechanism in the Chinese context. This study also indicates that leaders should concern the health of the ＂in-group＂ and the improvement of the ex- change quality of the ＂out-group＂ to reduce the employees＇ work stress.
