Although many scholars have explored the influencing factors of knowledge sharing, these studies focusing on positive influencing factors of knowledge sharing, few studies pay little attention to negative influencing factors of knowledge sharing. Thus, this study explores the impact of abusive supervision on knowledge sharing, especially examining the mediating role of organizational identification and the moderating of person-organization fit. This study has collected 348 questionnaires in two wave way. The results show that abusive supervision has significantly negative impact on knowledge sharing; organizational identification mediates the relationship between abusive supervision and knowledge; person-organizational fit moderates the effect of abusive supervision on knowledge sharing.
