A Study of Operational Efficiency of Commercial Banks for Financial Holding Company in Taiwan

[[abstract]]由於台灣金融機構家數過多、競爭劇烈，且中小金融機構效率不彰、容易倒閉，有被納入金控體系的需要，政府將2001年訂為金融改革元年，且修改相關法令並通過「金融控股公司」等六法，結合了銀行、證券及保險三大行業以增強我國金融業之競爭力。 本研究以25家本國銀行，包含現今11家「金融控股公司」下之商業銀行與14家「非金融控股公司」下之商業銀行為研究對象，資料來源為台灣經濟新報資料庫，研究期間為2002年至2006年底，以薪資支出、利息支出及非利息支出為投入變數；利息收入及非利息收入為產出變數，運用資料包絡分析法(Data Envelopment Analysis；DEA)及Malmquist生產力指數(Malmquist Productivity Index；MPI)，分別求算個別銀行之經營效率值與跨期成長率，來探討加入金控體系之銀行是否真的優於未加入金控體系之銀行。 研究結果發現，金控公司和非金控公司子銀行主要的無效率原因皆來自規模無效率，必須依據規模報酬來改變其規模型態以降低無效率的情形，而在整體技術效率的表現，金控公司子銀行並沒有較非金控公司子銀行更有效率。Malmquist生產力指數方面，以整體的總生產力變動來看，非金控公司子銀行是稍微優於金控公司子銀行。[[abstract]]Under the situation that the number of local financial institutions was too many thereby causing fierce competition and in view that medium-sized and small-sized financial institutions are required to be incorporated in the financial holding company in 2001 Under which banking securities and insurance sectors are encouraged to form the financial holding company in order to increase the competitiveness of domestic financial institutions This study focuses on the business activities by 25 domestic banks including 11 commercial banks which have been established by financial holding company and 14 commercial banks which have been established by non-financial holding company The data is collected from 2002 to 2006 The input variables are salary expenditures interest expenditures and non-interest expenditures and the output variables are interest income and non-interest income The data of this study are analysed by using Data Envelopment Analysis(DEA) and Malmquist Productivity Index(MPI) in order to find out the management efficiency and the inter-temporal change The empirical results indicate that the cause of inefficiency for the banks of financial holding company and non-financial holding company is scale inefficiency Therefore it must change operational scale in order to improve efficiency according to scale returns In technical efficiency the banks of financial holding company are not more efficient than the banks of non-financial holding company In Malmquist Productivity Index the banks of non-financial holding company are slightly superior than the banks of financial holding company in total factor productivity chang
