本研究以台北市政府員工為例,探討轉換型領導、內在動機、組織承諾對組織公民行為之影響。研究結果發現轉換型領導、內在動機、組織承諾對員工的組織公民行為有正向的影響;內在動機、組織承諾對組織公民行為有正向的影響。除此之外,轉換型領導會透過內在動機之中介,影響組織公民行為的展現;轉換型領導也會透組織承諾之中介,影響組織公民行為的展現。本研究針對研究結果進行討論,並針對人力資源管理實務後續研究提出建議。 ;With the sample of public employees in Taipei city government, this research is to investigate the relationships among transformational leadership, intrinsic motivation, organizational commitment, and organizational citizenship behavior.
