Abstract: With the increasing attention on subgroups and human relationships in Chinese society, employees′ activities are closely related to groups. Employees′ attention to subgroups has become an important factor affecting their organizational citizenship behaviors. Based on taskwork network theory, this study takes a survey from 137 teams and 796 employees in Shandong province as the research sample, and applies cross-level research methods to construct a theoretical model about the influence of demographic faultline and information faultline on employees′ organizational citizenship behavior, trying to test the moderating role of leader inclusion in the subgroups and leaders′ emotional intelligence on this relationship. The results show that both demographic faultline and information faultline have a negative effect on employees′ organizational citizenship behaviors,and leaders′ emotional intelligence positively moderates the relationship between both types of faultline and employees′ organizational citizenship behaviors. The study clarifies the relationship between the two types of faultline and employees′ organizational citizenship behaviors, and confirms the negative effects of the two types of faultline are reversed under the condition of high leadership emotional intelligence.

Key words: group faultline, organizational citizenship behaviors；emotional intelligence, leader inclusion in the subgroups, cross-level
