Abstract: Drawing on the samples of 163 management team members from 14 colleges and universities in China, this study employs correlation analysis and statistical analysis to explore the relationship between two types of team conflict, organizational justice and organizational citizenship behavior, and then to examine the mediating role of organizational justice. The results from hierarchical regression analysis indicate that task conflict has significantly "inverted U" shape impact on organizational citizenship behavior, organizational justice partly mediates the relationship between task conflict and organizational citizenship behavior. Furthermore, relationship conflict has significantly negative effect on organizational citizenship behavior, while organizational justice fully mediates the relationship between relationship conflict and organizational citizenship behavior.
