1990年以來，數位傳播科技的迅速發展，使得媒體產業面臨結構變遷，媒體企業再造（business reengineering）不只是產業界的重要行動，同時也是學術界研究的重要領域之一。媒體企業再造的「關鍵成功因素」（key success factors）是學術界與實務界共同關心的議題，已有不少的研究結果（楊志弘，2004）。但是，由於媒體各部門工作性質迥異，因此存在著各自不同的領導型態，而領導型態對於企業再造的實質運作具有顯著影響（楊志弘，2004），因此，本研究將針對不同部門的領導型態進一步分析企業再造關鍵成功因素的課題。 本研究選取東森華榮傳播事業集團之東森電視臺為研究對象，目的在探討東森電視臺不同部門領導型態之差異；東森電視臺不同部門企業再造關鍵成功因素重要度認知之差異，以及領導型態與企業再造關鍵成功因素重要度認知之間的關聯性。本研究方法係採問卷調查法，按「分層比例隨機抽樣法」，選出東森電視臺的主管和員工為施測對象。總計發放問卷300份，回收有效問卷264份，有效率達88％。依據文獻探討、問卷設計與分析後，本研究主要研究發現如下： （一）東森電視臺各部門領導型態傾向「仁慈權威型」與「諮商民主型」。整體而言，東森電視臺新聞部與節目部的領導型態偏向「仁慈權威型」；而業務部、工程製播部與行政管理部則偏向「諮商民主型」。 （二）東森電視臺各部門企業再造關鍵成功因素重要度認知存在有顯著差異。其中，新聞部視領導決策為最重要的關鍵成功因素；節目部與業務部則最重視目標整合；工程製播部認為人力資源最重要，而行政管理則傾向於認知資訊運用較重要。 （三）東森電視臺之領導型態與企業再造關鍵成功因素重要度認知具有顯著相關。 研究顯示領導型態構面中的組織結構、激勵特性、績效目標與資源控制構面能有效預測企業再造關鍵成功因素重要度認知達39.4％的總變異量。 本研究貢獻在於納入領導型態來探求企業再造關鍵成功因素重要度認知的差異，由於以往的研究多在探討企業再造關鍵成功因素與實施績效之間的關聯性，而本研究擬從更高層面切入，冀望以領導型態的不同來檢視企業再造關鍵成功因素的重要度認知，應可獲得較客觀的結果。

Since 1990, the digital science rapid development has caused the media industry faced with the structure change, the business reengineering (BR) of media not only the industrial field important motion, simultaneously also is one of the important domain which the academic circles studies. The media key success factors (KSF) of BR is a subject which the academic circles and the industrial field cared about together, had many findings. But, the job functions of media various departments is different, therefore has different leadership style. The leadership style makes reveals influence to the substantive operation of media, therefore, this research will aim at the leadership style of different department and further will analyze the topic of KSF of BR. The research select the Eastern television (ETTV) of Eastern Broadcasting Co., Ltd for research object. The main goal is to discussion the difference of ETTV's leadership style in each department. ETTV's each department cognition the important of KSF of BR as well as the connection between the leadership style and the important of KSF of BR. This study adopts questionnaire survey research methods and “Stratified rate random Sampling” sampling method. Distributing 300 questionnaires to high-level managers, mid-level managers and line staffs of ETTV and the recycling effectively questionnaires are 264, effectiveness rate is 88%. After the literature discussion, questionnaires design and the analysis, the main finding of this research are as follows: (1) The leadership styles of various departments in ETTV are tend to “benevolent-authoritative” and “consultative-democrative”. Overall, News department and Program department's leadership styles is tend to “benevolent-authoritative”. The Busniess department, the Project system broadcasts, and the Administration department are tend to “consultative-democrative” (2) The components of KSF of BR in ETTV's departments had made significant difference. Among them, the news department regards the leadership decision-making to become the most important KSF; Program department and Service department most takes the goal conformity; The project system broadcasts think the human resources are importantly, and the Administration department regards as the information utilization is more important. (3) The leadership styles and KSF of BR in ETTV's departments are correlation. Demonstrated the components of the organizational structure, the drive characteristic, the achievements goal and the resources control can efficiently forecast the KSF of BR to reach 39.4% total variations quantities. This research contribution lies in brings the leadership styles to seek the difference on KSF of BR. Because the former research are focus on the connection beetweet KSF implementation achievements connection, but this research draws up from a higher stratification plane cuts into differently, hopes the leadership style can inspect the KSF of BR, it should be possible to obtain a more objective result.
