We apply a translog cost function, a panel data fix-effect model, different definitions for output (by revenue and asset), as well as economies of scale and economies of scope index, to analyze the cost efficiency of 13 subsidiary banks of FHC and 30 banks of non-FHC for 2002-2006 and to see whether the FHC Act can bring more benefits and improve efficiency for Taiwan’s bank industry. Our major findings are: (1) Economies of scale: the subsidiary banks of FHC don’t have economies of scale under the two different definitions for output. (2) Economies of scope: if output is defined by revenue, fee revenue has cost complementary for subsidiary banks of FHC while cost revenue has for banks of non-FHC. If output is defined by asset, only loan has cost complementary with investment asset for both. (3) For FHC, mergers and acquisitions cross different industries don’t improve the cost efficiency of its’ subsidiary banks. (4) On average, the subsidiary banks of FHC don’t reveal better cost efficiency than the banks of non-FHC.目 錄試委員會審定書………………………………………………………………... i謝……………………………………………………………………………….... ii文摘要…………………………………………………………………………... iii文摘要……………………………………………………………………..……. iv一章 導論………………………………………………………………….. 1.1研究背景與動機……………………………………...…………………… 1.2研究目的…………………………………………………...…………….. 6.3本文架構………………………………………….……………………… 7二章 文獻探討……………………………………………………………… 9.1購併的動機與方式……………………………………...……………….. 9.2績效的定義與衡量………………………………………………………. 10.3銀行業投入產出的衡量……………………….………………………… 12.4 效率分析方式………………………………...…………………………. 14三章 實證模型的建立………………………………………………………. 18.1實證模型的建立………………………………….……………………… 18.1.1選擇Panel data的優點與相關模型………….…….………………... 18.1.2超越對數(translog)函數型式…………….……………...…………… 21.1.3規模經濟與範疇經濟……………………………………...………… 22.1.4實證模型設定……………………………………………..…………. 23.2變數定義與資料說明……………………………………………………. 34四章 實證結果分析………………………………………………… 39.1收入面產出實證分析……………………………….…………………… 39.2資產面產出實證分析……………………………………………………. 47.3 總結………………………………………………………………..…….. 54五章 結論與建議…………………………………………………………… 57考文獻…………………………………………………………………….……. 59application/pdf1630182 bytesapplication/pdfen-US銀行效率成本效率超越對數成本函數panel data 固定效果模型Banking efficiencyCost efficiencyTranslog cost functionPanel data fix-effect modelthesishttp://ntur.lib.ntu.edu.tw/bitstream/246246/179185/1/ntu-96-R93323026-1.pdf
