Abstract This study discusses and tests the influencing factors and process mechanism of the formation of transactive memory system in knowledge team. 84 knowledge teams along with a total of 338 members were used as research subjects. From the aspects of expertise, task and relationship, an integrated model of “environmental foundationinternal conditionknowledge system” is proposed along with shared mental model and behavioral trust as mediators. Empirical results show that the expertise heterogeneity, task interdependence and tie strength have positive impact on transactive memory system. Shared mental model and behavior trust fully mediate the impacts of expertise heterogeneity and task interdependence on transactive memory system, and partially mediate the effect of tie strength on transactive memory system. Among the control variables, team size has negative effect on transactive memory system, team history and task complexity have positive influence on transactive memory system.
