金控子銀行與一般銀行績效比較

Abstract

自2001 年金融控股公司法實施以來，目前台灣已有14 家金控成立，一般認為金控因具有交叉行銷及一次購足等優勢，故其旗下子銀行的績效也較一般獨立子銀行之績效為優，故本文目的在研究金控子銀行與非金控子銀行間績效是否有所差異，以及金控事業主體不同（如保險、銀行或證券），是否會影響旗下子銀行之績效。本文第一階段使用資料包絡分析法，分析台灣十一家金控子銀行及十三家獨立銀行之績效是否不同。第二階段利用吸引力測度(attractiveness measure)及進步測度(progress measure)來區辨各評估單位(DMUs)間的績效優劣及排名。研究發現，金控子銀行績效顯著優於非金控子銀行，以銀行為金控事業主體之金控子銀行其績效優於事業主體為保險與證券之金控旗下子銀行。本文作者亦依據分層、吸引力測度與進步測度為各評估單位建立標竿，並建議銀行管理當局利用標竿遞進學習。

The Financial Holding Company Act passed in 2001 and allows banks to combine with insurance firms, security brokerages and to form Financial Holdings. It is thought that the performance of the bank subsidiary of a Financial Holding Company (FHC) is better than the independent bank, because the FHC develops cross-selling strategy and provides a one-stop shopping convenience for its bank subsidiary’s customers. The purpose of this research is to determine whether a bank subsidiary in FHC or independent bank has a greater efficiency and ascertain whether different main businesses (banking, insurance, securities) of a FHC affects the performance of its bank subsidiary. Applying a non-parametric frontier approach, data envelopment analysis (DEA), to evaluate the relative efficiencies of 11 bank subsidiaries of Financial Holding Companies (FHCs) and 13 independent commercial banks in Taiwan, this thesis provides evidences that (1) bank subsidiary of a FHC outperforms independent banks; (2) the types of main businesses of a FHC does have influence on the performance of its subsidiary; the ranking of performances from good to bad as follows: banking, insurance and securities. In addition, this thesis measures context-dependent bank performance for different efficiency levels. This context-dependent DEA model allows (1) the benchmarking of our Decision-Making units (DMUs) compared to its competitors; (2) measuring attractiveness and progress and drawing a benchmark-learning roadmap as a tool for ranking all DMUs.
