| dc.description.abstract (摘要) | 過去幾年學術界發現，多角化經營會減損公司績效，此結果有別於早期之實證研究。在此情況下，為何高階主管會進行多角化經營？其多角化動機為何？本研究於是從代理理論觀點，參考Aggarwal and Samwick(2003)之模型，探討主導公司管理階層多角化之動機。與過去研究最大之不同處在於：本文在推論過程中，同時納入代理理論兩個不同觀點－趨避風險及滿足私人利益，藉由控制多角化程度之變動，觀察高階主管誘因契約與公司績效連結性強弱，以此推論隱含之高階管理者多角化動機。 本研究認為：若高階主管持股比率與多角化程度呈現負相關，同時在多角化程度變動下，高階主管持股比率與公司績效之連結性越強，則主導高階主管多角化之動機為趨避風險；反之，若高階主管持股比率與多角化程度呈現正相關，同時在多角化程度變動下，高階主管持股比率與公司績效之連結性越弱，則主導高階主管多角化之動機為滿足私人利益。本研究以高階主管持股比率替代高階主管誘因契約，以Entropy指標衡量公司多角化程度，以Tobin’s Q衡量公司績效，在實證時，又將高階主管細分為經營團隊與董事長兩組。 實證結果顯示：在經營團隊組，並無明顯證據顯示其多角化動機由和因素所主導，可能原因為台灣公司家族企業比重高，使專業經理人難以進入權力核心，左右多角化決策，使得實證結果並不顯著；在董事長組，則明顯指出，其多角化動機為趨避風險。換句話說，由於董事長個人財富、職位及聲譽與公司績效關連性很大，因此希望藉由多角化經營降低本身暴露之非系統風險。本研究同時發現，在此情況下，董事長私人利益與公司利益較無衝突，使多角化經營造成公司績效減損之幅度較小。 | zh_TW |
