英文摘要：

Core employees are the foundation of an enterprise. A good job security mechanism can help them to relieve their pressure, to improve their mental environment and to increase satisfaction; hence they can work whole-heartedly and improve working efficiency. Through empirical study, we find that job security contents two aspects： working guarantee and right protection. Job security plays a positive role in affective commitment and job satisfaction. Job embeddedness works entirely as an intermediation between job security and affeetive commitment, and works partially as an intermediation between job security and job satisfaction. Therefore, as a way of preventing brain drain, job security gives full play to improving the employees＇ working attitude.
