中文摘要：

旨在探讨工作不安全感对员工工作幸福感和工作绩效（上级评定）的影响，以及一般自我效能感在其中的作用机制。研究采用问卷调查的方法，共收集到513个有效样本。数据分析采用层级回归分析的方法。研究结果发现：（I）工作不安全感对员工工作幸福感和工作绩效都有显著的消极影响；（2）一般自我效能感对工作不安全感与身体健康、心理健康之间关系具有显著的调节作用，但对工作满意度的调节作用不显著；（3）一般自我效能感对不安全感一工作绩效之间关系具有显著的调节作用。这就表明，在当今处于转型期的中国社会里，工作不安全感是影响员工工作幸福感和工作绩效的一个重要压力源，而一般自我效能感可以发挥有效的调节作用。

Nevertheless, general self-efficacy did not have any moderating effect on the relationship between job insecurity and job satisfaction. The significant moderating role of general self-efficacy on the relationship between job insecurity and job
