中文論文摘要

自民國八十年政府解除金融管制以來，銀行總家數及分支機構家數都快速的成長，銀行家數的急速擴張造成金融業過度的競爭，使得銀行業吸收存款的業務愈來愈困難，銀行業的生存空間亦不斷被壓縮。這種現象不僅僅存在於台灣，各國政府亦面臨相同的挑戰，美國於一九九九年十一月通過「金融服務現代化法」( Gramm- Leach- Bliley Act )，藉以提高美國金融機構在國際上之競爭力；我國亦於民國九十年十一月一日實施「金融控股公司法」，此法打破了金融業不得跨行業經營的限制，但是，銀行從事多角化的經營是否能提高銀行經營上的績效，值得作進一步的探討。故本文之主要研究目的在於瞭解商業銀行加入金融控股公司前後，其經營績效及生產力之變化情形。

在研究方法上，本文利用資料包絡分析法(Data Envelopment Analysis；DEA)評估各銀行間之經營效率值，包括三項投入變數：勞動、資金及資本；三項產出變數：放款總額、投資總額及其他收入。在得到各銀行間的經營效率值後，本文進一步以Mann-Whitney檢定樣本組(金控成員之商業銀行)及對照組(非金控成員之商業銀行)兩組樣本在各期間的經營效率值是否有顯著差異。另外，本文應用Malmquist productivity index求得樣本組及對照組在金融控股公司成立前、後期間生產力值的變化，同樣地，應用Mann-Whitney分別檢定此兩組樣本在成立前、後期間的生產力值間是否有顯著差異。

在樣本資料的選擇上，根據財政部金融局統計資料顯示截至90年底止，國內共有14家金融控股公司成立，除了新光金控及國票金控在其集團中沒有商業銀行成員外，其餘皆有一家以上的商業銀行成員，本文選擇15家為金控成員的商業銀行為樣本組，不是金控成員的24家商業銀行為對照組。資料來源包括金融業務統計輯要及本國銀行營運季報，樣本期間自民國89年1月至民國92年6月底止，以半年為一期的基準，共計有七個期間。

實證結果發現，民國89年上半年至民國91年上半年之各期間，樣本組的純技術效率部分，在5%顯著水準下並未顯著優於對照組，但是，在民國91年下半年及92年上半年，則顯著優於對照組。另外，以生產力指標驗證發現，樣本組的效率變動在10%的顯著水準下，成立後期間顯著優於成立前期間，對照組的技術變動在1%的顯著水準下，成立後期間顯著優於成立前期間。藉由本文的實證分析，可以得知商業銀行在加入金融控股公司後確實會對其經營績效及生產力有提昇效果。

Abstract

Taiwan government has opened up the establishment of financial holding corporations since July 2001. Under this system, one financial holding corporation can involve banking, security and insurance business at the same time. The purpose of this paper is then to study the efficiency and productivity growth of commercial banks in Taiwan before and after financial holding corporations’ establishment.

We employ a Data Envelopment Analysis (DEA) approach to generate efficiency indices as well as Malmquist productivity index for each bank. In addition, we use Mann-Whitney criteria to investigate the difference of the efficiency indices between member and non-member banks of financial holding corporations. With the same method, we also examine the difference of the efficiency indices between two periods--before or after the financial holding corporations were established.

According to Bureau of Money Affairs, Ministry of Finance, Taiwan, there are 14 financial holding corporations. We chose 15 member banks of financial holding corporations and 24 non-member banks of financial holding corporations as our sample banks. Data in used were drawn mainly from Financial Transaction Statistics. We use the semiannual data sets for each of the time series. The time period covered is from January 2000 to June 2003.

From this study, we can find the following results. First, the member banks of financial holding corporation are more efficient then the non-member banks. Second, member banks as well as non-member banks of financial holding corporation both demonstrate a greater technical progress in the second time period.
