本研究旨在探討台北市私立幼稚園園長轉型領導行為與成員組織承諾之關係，先以文獻探討為基礎，然後編製問卷實施調查，以蒐集實徵性資料。調查對象為台北市私立幼稚園成員(含合格教師、行政人員、職工)共617人；調查工具則為自編之「幼稚園園長與成員行為表現調查問卷」。問卷回收420份，其資料經統計分析，有下列主要發現： 一、多數幼稚園成員對園長轉型領導的覺知情形良好，且幼稚園成員的組織承 諾現況良好。 二、幼稚園成員對園長轉型領導的覺知程度會因成員的性別、年齡的不同而有顯著差異。 三、幼稚園成員對園長轉型領導的覺知程度不因成員的學歷、服務年資、職務及幼稚園規模而有差異。 四、幼稚園成員的組織承諾會因成員的年齡、學歷及服務年資的不同而有所差異。 五、幼稚園成員的組織承諾不因成員的性別、職務及幼稚園規模而有差異。 六、幼稚園園長轉型領導行為與幼稚園成員之組織承諾呈現高度正相關。 七、幼稚園園長轉型領導行為之「智性刺激」對幼稚園成員組織承諾具有較高之預測力。 基於上述研究發現，本研究提出相關建議，供私立幼稚園園長改進領導行為，以增進幼稚園同仁之組織承諾的參考。 This study was to explore the relationship between principals’ transformational leadership and employees’ organizational commitment of private kindergartens in Taipei City.
