指導教授 : 歐陽豪

摘要


本研究旨在探討金融集團多角化策略與年報資訊揭露對組成公司市場績效之影響,並討論金融控股公司型態對『多角化策略與績效』間之關係的調節效果。本研究採用恩索比(Entropy)方法計算集團多角化的程度,以台灣2003至2009年金融集團企業之上市櫃公司為樣本進行多角化指標計算,並遵循證基會第8屆資訊揭露評鑑中的50項年報資訊揭露指標,以內容分析法進行評分,實證結果發現:「集團總體多角化指標(DT)」對市場績效-杜賓Q(Tobin’s Q)為顯著正向的影響,「集團整體相關多角化指標 (DR)」與「非相關多角化指標 (DU)」對杜賓Q(Tobin’s Q)分別顯著正向與不顯著負向的影響,年報資訊揭露對公司績效為不顯著的正向影響;金融控股公司型態對「集團總體多角化」及「相關多角化」有減弱的調節效果,金融控股公司型態對「非相關多角化」則有增強的調節效果。本研究的貢獻在三方面:第一,補充了台灣金融集團多角化策略及其組成細項對集團組成公司績效影響之實證證據;第二,補充了年報資訊揭露程度對金融集團績效之實證證據;第三,驗證了金融控股公司對多角化策略的調節效果。
