隨著兩岸人身保險業的交流合作不斷加深，有必要對兩岸人身保險業的經營效率進行深入探討。本文利用隨機邊界法來評估兩岸90家人壽保險公司2006-2011年總共六年的投入要素經營效率。本文將員工人數、股東權益資本、負債資本三項作為投入要素，營業收入作為產出要素。實證結果發現：在勞動力投入要素方面，台灣地區的平均效率值普遍高於中國大陸；負債資本投入要素方面，中國大陸人壽保險公司的負債資本平均效率值高於台灣地區；股東權益資本投入要素方面，兩岸效率值並無顯著差距，台灣地區人壽保險公司的平均效率值略高於中國大陸。

As the communication and cooperation in life insurance industry across the Taiwan Strait are becoming deeper, it is necessary to have a deeper research on the efficiency of life insurance industry across the strait. This paper applies stochastic frontier approach extend from Zhou et al. (2012) to estimate the input factors efficiency of the 90 life insurance companies from 2006 to 2011. We treat the number of employees, shareholder's equity, and the liability as the input factors, while the operating revenue as the output factor. Our major empirical findings are as follows: The average labor efficiency score of Taiwan areas is higher than that in mainland China. Companies in mainland China get a better average liability efficiency score than those in Taiwan. The average shareholder's equity efficiency scores in the two areas are quite close, while companies in Taiwan do a little bit better.
