Although the importance of leadership for innovation processes has been acknowledged, the understanding of the relationships between leadership styles and levels of innovation in work teams is still limited. This study among team managers and team members of 133 Spanish bank branches (i.e., work teams) investigated whether the influence of charismatic leadership on work team innovative behavior comes about via team potency, and whether the relationship between charismatic leadership and team potency is moderated by the level of task interdependence within the team. Data were collected at three different time points. Results of structural equation modeling showed that only at high levels of task interdependence, team managers’ charismatic leadership at time 1 was significantly positively related to an increase in team potency at time 2, which in turn was positively related to manager ratings of their work teams’ innovative behavior at time 3. This means that only at high levels of task interdependence, charismatic leadership had a significant indirect effect on team innovative behavior via team potency. Thus, our study sheds light on the boundary conditions of this effect.

尽管领导力对于创新过程的重要性已得到认可，但对领导风格与工作团队中创新水平之间关系的理解仍然有限。这项对133个西班牙银行分支机构（即工作团队）的团队经理和团队成员进行的研究调查了魅力型领导力对工作团队创新行为的影响是否通过团队效力来实现，以及魅力型领导力与团队效力之间的关系是否通过以下方式得到缓解：团队中任务相互依存的程度。在三个不同的时间点收集数据。结构方程模型的结果表明，只有在任务相互依赖程度很高的情况下，团队经理在第1时刻的超凡领导才能才与时间在第2时刻的团队效能显着正相关。这反过来与经理在时间3对其工作团队的创新行为的评价呈正相关。这意味着，只有在高度的任务相互依赖性下，超凡魅力的领导才能通过团队效能对团队创新行为产生重大的间接影响。因此，我们的研究揭示了这种效应的边界条件。
