IT기업에서의 공유리더십이 혁신행동에 미치는 영향 : 긍정심리자본과 지식공유의도의 매개효과를 중심으로

This study examines the effect of shared leadership on employees’ innovative behavior and investigates the mediating roles of positive psychological capital and knowledge sharing intention. Using survey data collected from 415 employees working in IT firms in the Seoul–Gyeonggi region, structural equation modeling (SEM) was employed to test the proposed research model. The results indicate that shared leadership has significant positive effects on positive psychological capital, knowledge sharing intention, and innovative behavior. Knowledge sharing intention emerged as the strongest proximal antecedent of innovative behavior and partially mediated the relationship between shared leadership and innovative behavior. In contrast, positive psychological capital showed a positive indirect effect on innovative behavior through knowledge sharing intention but exerted a significant negative direct effect on innovative behavior, resulting in a non-supportive mediation effect in the expected direction. These findings suggest that the influence of shared leadership on innovative behavior is transmitted primarily through concrete behavioral intentions such as knowledge sharing rather than through the accumulation of psychological resources alone. Moreover, the results highlight a paradoxical effect of positive psychological capital, indicating that it may inhibit innovative behavior under certain contextual conditions. This study contributes to the literature by clarifying the multi-level mechanism linking shared leadership, psychological resources, and innovative behavior, and by offering practical implications for fostering innovation through leadership and knowledge-sharing practices.
