The present study offers new theoretical insights into the dynamics of shared leadership. Integrating arguments from shared leadership and team development theory, we examine how shared leadership changes over the course of a project team's life cycle and how this pattern of change relates to team performance. Guided by shared leadership theory and project team literature, we also explore team‐level factors, which may alter the pattern of shared leadership development. In particular, we propose that in project teams shared leadership develops in a nonuniform way, approximating an inverted U‐shaped pattern, increasing early in the team's life cycle, peaking around the midpoint, and then decreasing in the later phase. In turn, this development pattern relates positively to team performance. We also extend theory by explaining how specific team characteristics influence the pattern of shared leadership development. Using a three‐study approach, we empirically examine the hypothesized relationships and conclude with a general discussion of the theoretical and practical implications of our findings.

共享领导力发展和团队绩效：共享领导力动态的新视角

本研究为共享领导的动力提供了新的理论见解。结合共享领导力和团队发展理论的论据，我们研究了共享领导力如何在项目团队生命周期中发生变化，以及这种变化模式与团队绩效之间的关系。在共享领导力理论和项目团队文献的指导下，我们还探索了团队层面的因素，这些因素可能会改变共享领导力发展的模式。特别是，我们建议项目团队中的共享领导力以不统一的方式发展，近似于倒U形模式，在团队生命周期的早期增加，在中点附近达到顶峰，然后在后期减少。反过来，这种发展模式与团队绩效成正比。我们还通过解释特定的团队特征如何影响共享领导力发展模式来扩展理论。使用三项研究方法，我们以经验方式检查了假设的关系，并以对我们发现的理论和实践意义的一般讨论作了总结。
