A Multilevel Study of Group Affective Tone and Team Innovation: A Moderated Mediation Model
基于拓展建构理论和威胁僵化假说，研究了变革型领导如何调节群体情感基调通过信息精加工影响团队创新的过程，发现积极情感基调通过信息精加工促进创新，且变革型领导增强该效应，但对消极情感基调的负面效应无缓解作用。
Drawing on broaden-and-build theory and threat-rigidity hypothesis, we theorized and tested a multilevel model to examine the moderating effects of transformational leadership (TFL) on the team-level process that links positive/negative group affective tone (PGAT/NGAT) to team innovation via information elaboration. Data were collected from 299 team members and 65 leaders from Taiwanese companies at two time points. The multilevel path analysis demonstrated support for a positive indirect effect of PGAT on team innovation via information elaboration and a negative indirect effect of NGAT on team innovation via information elaboration. The positive indirect effect of PGAT on team innovation via information elaboration was found to be stronger when TFL was high rather than low. However, TFL did not attenuate the negative effects of NGAT. Negative group affective tone was negatively related to information elaboration when TFL was high, whereas NGAT had no significant relationship with information elaboration when TFL was low. Theoretical and practical implications are discussed.
