鑑於以往文獻研究期間多著重於金融風暴前後的探討 (廖桂櫻,2008;張永青,2008;朱炫璉與吳志銘,2009),且過去文獻也因金控成立不久,取得的年度期間資料有限,加上法案的成立需經長時間方可看出其成效,而針對公營與民營、公股與非公股銀行,以及研究期間著重於金融控股公司法前後之議題亦不多見。因此,本研究建構2002年第四季至2015第三季,共國內八家泛公股銀行及二十二家非公股銀行之企業別資料 (firm-level panel data)。 首先,本研究運用資料包絡分析法 (data envelopment analysis,DEA) 求算效率值,比較泛公股銀行與非公股銀行,在金融控股公司法實施後之經營效率。進一步使用麥氏生產力 (malmquist productivity index,以下簡稱MPI) 衡量泛公股銀行與非公股銀行,在金融控股公司法實施後生產力之變動情形。本文納入過去文獻鮮少採用之評比機構評估銀行所使用之績效變數,及考量巴賽爾協議加入前後期之比較與相關之變數,使用了核心存款 (活期存款及定期存款) 與放款及貼現。其次,將效率值及MPI運用四象限圖進行比較分析。結果顯示: 一、泛公股銀行在經營效率上相較於非公股銀行的確具有優勢。 二、非公股銀行較有完善的管理效率,生產技術的進步也較快。 三、非公股銀行因傳統包袱少、彈性相對較公股銀行大,未來成長深 具發展潛力。 綜合以上的結果發現,金融控股公司法實施後,金融業邁向一次購足型態發展,技術方面持續進步以及具有完善的管理制度,有助於提升經營效率及生產力。
This paper constructs the firm-level panel data of 8 public shares banks and 22 non-public shares banks from the fourth season of year 2002 to the third season of year 2015. First, this study applies the data envelopment analysis (DEA) to measure efficiency, and then we compare the efficiency between public and non-public shares banks after the implement of Financial Holding Company Act. Further, we use malmquist productivity index (MPI) to evaluate the productivity change between public and non-public shares banks after the implement of Financial Holding Company Act. This paper adopts the rare used of credit rating variable, and takes into account the variable of Basel II. This study takes into core deposit (demand deposits and time deposits) of appraised organization using performance variables that rare discuss in previous literatures. Second, This study uses four-quadrant diagram of efficiency value and malmquist productivity index. Compare with previous studies, this study extension of the period and with more detailed variables. The results show that : 1. Public shares banks compared to non-public shares banks have an advantage in operating efficiency. 2. Non-public shares banks have better management efficiency than public shares banks. Its production and technological progress are also faster than public shares banks. 3. Because non-public shares banks have less burden of tradition and more elastic than public shares banks, that have future growth potential . Based on the above results show that after the implementation of the Financial Holding Company Act, the financial sector towards the development of one-stop shopping patterns, technological advances and continued with a sound management system help to improve operational efficiency and productivity.
