| Summary: | 博士 === 元智大學 === 管理學院博士班 === 100 === This thesis consists of two independent studies that mainly are to delve into the obscure and intricate relationships between transformational leadership (TL) and organizational citizenship behavior (OCB). Study 1 is to examine a conceptual model linking concepts of TL and OCB, with knowledge sharing, trust and empowerment as important mediators in the causal relationships. As hypothesized, the results showed that TL was significantly related to knowledge sharing, trust and empowerment. Moreover, knowledge sharing, trust and empowerment were significantly related to OCB. This study also verified that knowledge sharing, trust, and empowerment fully mediated the relationship between TL and OCB. Hence, the findings from this study advance understanding of the relationship between them. Study 2 is to explore the mediating effect of empowerment on the relationship between TL, job characteristics and OCB. The results showed that TL had significant positive relationships with JC and OCB. JC also significantly related to OCB. Besides, the results supported the hypothesis that empowerment had a partial mediating effect on the relationship between JC and OCB. However, empowerment did not mediate the relationship between TL and OCB. The implications of the results contribute profoundly meaning to researchers and practicing managers.
