中文摘要：

弱的工作边界可以实现非工作向工作的渗透，从而有助于员工平衡工作与生活，降低工作压力，但是过弱的工作边界因为非工作向工作渗透过多。反而会引起他们工作压力增加．因此工作边界强度与工作压力之间存在U型关系。然而．在什么条件下工作边界强度与工作压力的关系发生方向性变化，尚无定论。本文基于个人一环境匹配理论，提出员工个人对工作边界强度的偏好与实际工作边界强度的匹配程度在这两者关系中起着决定性的调节作用。本文通过问卷调查方式。验证了假设，即伴随着工作边界强度的减弱，员工工作压力先减少后增加。拐点处工作边界强度为5．3988（以7点量表来测），偏向于较强的工作边界：当员工的工作边界强度趋近于其偏好时其工作压力降低，但当工作边界强度超过其偏好时其工作压力增加。论文最后围绕缓解员工工作压力．从工作边界管理以及与员工偏好相匹配的角度．提出了对策建议。

英文摘要：

Existed research has shown that weak work boundary has contributed to achieve mutual permeablity between work and non-work so as to help employees balance work-life and ease work stress. Whereas, overly weak work boundary which means too much penetration between work and non-work, will lead to the frequent conversion among different roles for employees, and increase their work stress instead. Thus there should be a U-shaped relationship between work boundary strength and employee＇s work stress. However, there isn＇t a determined conclusion that in which conditions the relationship between work boundary strength and employee＇s work stress will change in direction. Based on person--environment fit theory, the authors put forward that the consistency of personal preference and organization given in work boundary strength plays a decisive role in moderating these two variables. This paper verified the hypothesis by questionnaire, which is： Accompanied with an increase in work boundary strength, the work stress of employees will firstly increase and then decrease, and get 5.3988 （7-point likert scale） in turning point of work boundary strength, prefer to stronger work boundary; When the work boundary strength rises to approach preferences of employees, their work stress will decrease, when it exceeds preferences, their work stress begin to increase. At the last part, some countermeasures and suggestions on work stress management aimed at employees of different preferences are given.
