资质过高感对员工知识共享行为的影响:一个被调节的中介模型

The Influence of Perceived Overqualification on Employees' Knowledge Sharing Behavior:a Moderated Mediation Model

基于差异-减少机制和自我验证理论,探讨资质过高感对员工知识共享行为的影响机制和边界条件。结果表明:资质过高感显著负向影响员工知识共享行为;核心自我评价在资质过高感与员工知识共享行为的负向关系中起完全中介作用;领导政治技能调节了资质过高感与员工核心自我评价的关系,领导政治技能越高,资质过高感对员工核心自我评价的负向影响越小;领导政治技能调节了资质过高感通过核心自我评价对员工知识共享行为的间接影响,领导政治技能越高,资质过高感对员工知识共享行为的影响就越小。

Based on the discrepancy-reduction mechanism and self-verification theory,this paper explores the perceived overqualification effects on employee'knowledge sharing behavior and its mechanism.The results show that:perceived overqualification has a significant negative influence on employees'knowledge sharing behavior;core self-evaluations play a full mediating role in the negative relationship between perceived overqualification and employees'knowledge sharing behavior;leader political skill negatively moderated the relationship between perceived overqualification and employee core self-evaluations;leader political skill also negatively moderated the indirect relationship between perceived overqualification and knowledge sharing behavior through employees'core self-evaluations.
