In order to explore the relationship between team knowledge heterogeneity， team conflict and team performance of bidding procurement project review committee， based on theoretical derivation， this paper puts forward a research hypothesis，constructs an analysis model， and uses regression equation model to verify the relationship of the above three parties. The results show a negative correlation between team knowledge heterogeneity and team performance， and a positive one between team knowledge heterogeneity and cognitive conflict and emotional conflict.There is no correlation between cognitive conflict and team performance， and emotional conflict plays a mediating role between team knowledge heterogeneity and team performance of the bidding procurement project review committee.The research explores the overall mechanism of the heterogeneity of explicit and implicit knowledge of the bidding procurement project review committee team，reveals the formation mechanism of cognitive conflict risk and emotional conflict risk and points out the dynamic change of cognitive conflict in the operation and evolution of team organization system.As a result， itexpands the scope of application of the theoretical basis of organizational behavior and enriches the research achievements in the field of organizational behavior.
