Although employee creativity has been identified to promote organizational competitiveness, its effect on leader empowering behaviors remains underexplored. This study investigated the underlying mechanism and boundary condition under which employee creativity influences leader empowering behaviors. Drawn on social exchange theory and similarity-attraction theory, this study developed a moderated-mediation model in which supervisor–subordinate guanxi serves as the intervening mechanism and supervisor–subordinate similarity serves as a boundary condition influencing this relationship. Using three-wave, time-lagged survey data collected from 309 supervisor–subordinate dyads, this study found that supervisor–subordinate guanxi mediates the relationship between employee creativity and leader empowering behaviors, and that this relationship is stronger when supervisor–subordinate similarity is high rather than low. Finally, theoretical and practical implications were discussed.

Guanxi refers to the quality of social interaction outside of work, developing through social activities. This article explores the antecedent (core self-evaluation, CSE) and consequence (job satisfaction) of the supervisor–subordinate guanxi for identifying the beneficial effect of guanxi. I also consider the effects of (dis)similarity of CSE which refers to individuals’ appraisals of their own worthiness, effectiveness, and capability. The data include 89 supervisors and their corresponding 437 subordinates from financial banks in Taiwan. The results indicate that CSE of the supervisor and subordinate positively relates to their own perceptions of guanxi and job satisfaction. Guanxi acts mediation between CSE and job satisfaction for supervisors and subordinates. The similarity effect of CSE is mostly prevalent for guanxi and job satisfaction. The findings offer implications for selecting an appropriate employee who are comparatively fit with management.
