台灣地區產物保險公司的經營效率－投入差額調整方法之應用Efficiency of Non-Life Insurance Companies in Taiwan: An Application

摘要
本文採用Fried et al.(2002)提出的三階段方法來衡量台灣地區產物保險公司的經營效率，並分析影響投入差額的環境變數。研究結果發現，增加分支機構數可顯著降低權益資本差額和佣金費用差額；擴張保險公司規模可顯著降低負債資本差額；擴張保險公司規模會顯著提高權益資本差額；而外國所有權則顯著降低本文的三項投入差額。
關鍵字：三階段方法、經營效率、投入差額
Abstract
This paper adopts the three-stage analysis proposed by Fried et al.(2002) to measure the managerial efficiency of non-life insurance companies in Taiwan. Environmental variables affecting input slacks are also analyzed. The number of branches significantly reduces slacks of equity capital and commission expenses. The scale significantly decreases slacks of total liabilities but increases slacks of equity capital. The foreign ownership significantly decreases all three input slacks.
Keywords: three-stage approach, managerial efficiency, input slacks
