Emergence of shared leadership networks in teams: An adaptive process perspective
研究了共享领导网络的三个维度（领导权分散、领导密度、情境匹配领导）在团队中的不同作用，发现交互记忆系统促进领导权分散和情境匹配领导，进而影响团队绩效。
Adaptive leadership theory suggests that shared leadership networks grow in a complex manner. We propose that leadership decentralization (the dispersion of leadership), leadership density (the total amount of leadership), and situationally-aligned leadership (SAL: leadership transitions to those who fit situation requirements) are distinct aspects of a shared leadership network and should be examined together to capture the development of shared leadership process. Through a study of 450 participants in 90 teams, we find that each of these three aspects of shared leadership plays a different role during shared leadership network emergence. Specifically, transactive memory systems (TMS) contribute to decentralized leadership structures, which in turn precipitate more dense leadership networks. We also find that TMS contributes to the most situationally aligned team member engaging in leadership. Both leadership density and SAL predict team performance. We discuss the theoretical and practical implications of these results.
