Abstract:Innovation demand drives the emergence of knowledge teams within various organizations. How to effectively utilize the skills and experiences (tacit knowledge) that are difficult to express and heterogeneous (tacit knowledge) possessed by knowledge-based talents within knowledge teams, which has become the key to promote the development of team innovation activities. Based on this, this paper explores the relationship between tacit knowledge heterogeneity and knowledge-based team creativity from the perspective of knowledge reconstruction, and examines the moderating role of cognitive conflict and team communication, and verifies it with the total effect moderating model. The results show that: (1) tacit knowledge heterogeneity has a significant positive impact on knowledge-based team creativity; (2) under the regulation of cognitive conflict and team communication, knowledge reconstruction plays a partial mediating role between tacit knowledge heterogeneity and knowledge-based team creativity; (3)Cognitive conflict regulates the relationship between tacit knowledge heterogeneity and team creativity. When the level of cognitive conflict is lower, the tacit knowledge heterogeneity has a higher positive effect on team creativity. But when this level is higher, cognitive conflict brings too many cognitive viewpoints and generates too much cognitive load, which can interfere with other members’ cognitive structure, thus weakening the positive impact of tacit knowledge heterogeneity on team creativity; (4) Team communication has a significant indirect moderating effect in the two stages of the model. The higher the proficiency level, the greater the influence of tacit knowledge heterogeneity on knowledge reconstruction and knowledge reconstruction on team creativity.
