Job embeddedness has a good prediction effect on employee turnover.How to improve job embeddedness has become an important issue in enterprise management.Based on social exchange theory and social identity theory,this paper explores the influence of leadership member exchange(LMX)on job embeddedness,and examines the mediating role of organizational identification and the moderating role of supervisor’s organizational embodiment.Through questionnaire survey,238 valid questionnaires were obtained.The research hypothesis was verified by correlation analysis,multiple regression analysis and confirmatory factor analysis.The results show that LMX has a positive effect on job embeddedness.Organizational identification plays a complete mediating role between LMX and job embeddedness.The supervisor’s organizational embodiment plays a moderating role in the relationship between LMX and organizational identification.A mediating moderation model between LMX and job embeddedness is finally validated.
