Abstract：From the perspective of knowledge management, this study establishes a mechanism model of team boundary spanning behavior’s influence on team creativity by taking knowledge integration capacity and knowledge heterogeneity as mediating variable and moderating variable respectively. Through the statistical analysis of 510 questionnaires by paired sampling from 78 teams in knowledge-based service industry, it is explored that three dimensions of team boundary spanning behavior (diplomatic behavior, coordination behavior and detection behavior) have a positive impact on team creativity, and this effect is achieved through the mediating role of knowledge integration capacity. In addition, knowledge heterogeneity plays a negative moderating role between knowledge integration capacity and team creativity.
