回顧97年，國內商業銀行剛擺脫雙卡陰影，卻又遭遇美國次級房貸風暴演變為全球金融危機等影響，多家銀行接連認列相關金融投資損失，致國內金融機構資產減損金額不斷擴大，削弱97年銀行業整體獲利。在財務吃緊的情況下，因而採取遇缺不補，以及各式降低成本的方法，除營運型態分別有外匯指定分行與非外匯指定分行並進行組織調整，加強控管風險確保獲利能力等。有關營運型態與組織調整是否會影響分行營運績效等是為本研究的動機。 本研究針對某公股上市銀行之國內分行共125家，用資料包絡分析法產出導向模式進行分析探討，投入變數為各分行之人員數與樓地板使用面積，產出變數則為活期性存款、定期性存款、個人金融放款、企業金融放款與扣備呆後盈餘，樣本期間為民國95年與民國97年作為組織調整之區分，藉以比較該商業銀行於此二期前後之分行營運效率差異。並依據地理位置座落都會區或非都會區與營運型態分為有、無外匯指定項目，藉以探討各該分行營運效率之差異，結果顯示該銀行在不同營運型態與組織調整前後，均對分行營運效率的表現有顯著差異。 For retrospect 2008, the domestic commercial bank just getting rid of the shade of double c-cards , it is influenced but encountered the sub-prime mortgage turmoil in the United States and developed into a global financial crisis .Many banks booked losses on relevant financial investments one after another, eroding overall banking industry profit performance.
