本研究採用2003-2006年共104筆年資料，將台灣壽險公司區分為三個群組：本國舊公司、本國新公司、外商公司，應用Metafrontier方法求算出共同技術率(Metatechnology ratio, MTR)，並比較各群組間技術效率的差異，更進一步透過迴歸分析，探討影響此差異的因素。實證結果分析如下： 一、 技術效率估計值以本國舊公司最佳，外商公司次之，本國新公司最差。研究結果顯示分群與整體間的效率值存在差異性，而分群的技術效率值皆高於整體的效率值。 二、 於MTR方面，本國舊公司為最接近共同邊界，其次是本國新公司，最遠離為外商公司。各群組內的壽險公司可以群組內MTR值為1的壽險公司為標竿，改善技術無效率的情形。 三、 影響本國舊公司MTR差異的因素，主要是大專以上比率。而本國新公司及外商公司差異原因為投資型證照比率、續約率及ROA等方面。 This study is based on the sample of 104 life insurance companies in Taiwan, starting fron year 2003 to year 2006. The sample was divided into three subgroups: old domestic company, new domestic company and foreign company. The Metafrontier method is applied to calculate Metatechnology ratio (MTR) and used to compare the differentials in technical efficiency among groups. The study also goes further using the regression model analysis to account for the different elements. The conclusions are summarized as follows: 1.The rank of technical efficiency estimate is in order old domestic company, foreign company and the new domestic company. The study shows that there is a significant differential in efficiency value between the subgroups and group as a whole. The technical efficiency values of three subgroups are higher than the whole group. 2.The MTR of domestic old company is close to the common frontier while new company takes second place and the foreign company is the last. The life insurance company can improve the technical inefficency using the companies with MTR equal to 1 as example. 3.The main influential factor accounting for the MTR differential is the quantity of college level workers as far as the domestic old company is concerned. However, for the new domestic company and the foreign company, the factors wedging off the common frontier are the investment certificate, renewal contract rate and ROA.
