Drawing from the IPO (Input–Process–Output) model, this study adopted a multilevel framework to investigate the dynamic mediating mechanisms that link group leader emotional intelligence (EI) with group performance. Based on a sample of 64 group leaders and 194 group members, this research applied multilevel structural equation modeling (SEM) and explored two mechanisms, namely group cohesion at the group level and person–group fit at the individual level in the relationship. Results revealed that group leader EI could improve group performance through enhancing group-level cohesion. At the individual level, it showed that group leader EI positively affected P-G fit. The paper utilized and expanded the IPO framework to explain the relationship between group leader EI and group performance from a multilevel perspective. Practical and theoretical implications are discussed.

本研究借鉴 IPO（输入-过程-输出）模型，采用多层次框架来研究将组长情绪智力 (EI) 与组绩效联系起来的动态中介机制。本研究以 64 名小组领导和 194 名小组成员为样本，应用多层次结构方程模型 (SEM) 并探索两种机制，即小组层次的小组凝聚力和个体层次的个人-小组契合关系。结果表明，组长 EI 可以通过增强组级凝聚力来提高组绩效。在个人层面，这表明组长 EI 对 PG 适合度有积极影响。该论文利用并扩展了IPO框架，从多层次的角度解释了组长EI与团队绩效之间的关系。
