The Lasting Benefits of Teams: Tie Vitality After Teams Disband
提出“关系活力”概念衡量团队解散后成员联系的持久性和可及性，研究发现团队关系资本和咨询网络密度正向影响关系活力，对理解团队长期价值有参考意义。
This paper introduces the concept of tie vitality, which indicates the durability and accessibility of team member connections after a team has disbanded as an additional measure of team effectiveness. The authors integrate the team and social network literatures to investigate the effects of team relational capital, team advice density, and dyadic similarities on tie vitality. Two field studies of graduate business student teams show that team relational capital—a psychological team-level state reflecting trust, identification, and mutual obligations among teammates—positively relates to tie vitality. Furthermore, team-level advice network density—a structured behavioral pattern of advice seeking and receiving—amplifies the positive relationship between relational capital and tie vitality. Results also indicate that dyad similarity relates to tie vitality, although it varies depending on which demographic characteristics are considered. Overall, findings indicate that the connections made in teams remain active after teams disband, with the extent of vitality depending on qualities developed during the team experience.
