Existing literatures primarily investigate the antecedents of team innovation from team characteristics and process perspectives,paying less attention to the role of external activities and internal-external interface activities.In this study,we introduce leader's boundary spanning behavior,and examine its influence on team innovation as well as the underlying mechanisms and boundary conditions.Analysis of a sample of 111 R & D teams indicates that team leader's boundary spanning behavior has a positive effect on team innovation,through the mediating role of knowledge sharing quality (not quantity).Further,team communication is found to marginally moderate leader's boundary spanning behavior,namely team innovation is better improved by leader's boundary spanning behavior when the communication with the team is better.The findings deepen our understanding of antecedents that foster team innovation,and provide implications for team innovation management.%团队创新是组织创新的基础.以往主要从团队特征和过程角度考察团队为何能创新,但在如今的开放生态系统中,边界活动的作用不容忽视.本研究引入“领导跨界行为”概念,基于知识管理视角考察了它对团队创新的影响效果、内在机制和边界条件.基于111个研发团队样本进行数据分析,结果发现:领导跨界行为对团队创新有正向影响,这种影响是通过团队成员知识分享质量(而非知识分享数量)的中介作用而实现的;此外,这种影响还受团队沟通质量的调节,即在团队沟通质量高的团队中,领导跨界行为更能促进团队创新.本研究有助于从新的视角理解团队创新的诱发机制,对企业的创新管理实践有一定的启示意义.
