本文主要利用隨機邊界法,結合Translog模型對2014 - 2016年15家台灣金控銀行公司的治理特性與其經營效率之相關性研究進行評估。實證指出:樣本期間台灣金控銀行之經營績效平均值為0.898,也就是說,樣本期間台灣銀行產業尚有10.20%(1-0.898)的無效率可以改進。外生變數對金控銀行無效率之估計係數中、董監席次(Z2)係數為 -0.223此意味董監席次(Z2)的增加對金控銀行的無效率有改善的正面影響。銀行之間的經營效率,樣本期間,經營效率最高的是前五名分別華南金、第一金、兆豐金、合庫金及玉山金。
Our research focus on using Stochastic Frontier Approach combined with translog model to evaluate the relationship of operating efficiency and governance characteristics of 15 financial holding companies in Taiwan from 2014-2016. Based on the empirical evidences of this research, the average value of the operating efficiency is 0.898 within the sample time. In other words, there is still 10.20% of operating inefficiency that can be adjusted and improved within this period. Based on the impact of exogenous variables to the coefficient of the inefficiency of Financial Holding Companies, the coefficient number of the Chairman of the Board is -0.223, which means that the increase of the number will have positive improvement towards the inefficiency of financial holding companies. According to the ranking of operating efficiency, Hua Nan Financial Holding Company was ranked the first, followed by First Financial Holding Company, Mega Financial Holding Company, Taiwan Cooperative Financial Holding Company, and E.Sun Financial Holding Company.
