本研究用意在探討遍佈全國之銀行分行的經營績效，並使用兩階段資料包絡分析法（Data envelopment analysis，DEA）以評估分行營運績效。研究對象為國內一金控體系下的分行進行個案研究，研究時間為2014年。有別於以往銀行進行績效評估時所使用的權重法。此次研究將會以一階段資料包絡法先找出分行作業面產出的效率，再透過二階段資料包絡法將分行投入的資源轉換為金融商品服務，再轉換為分行的獲利及經營績效，以深入了解分行投入資源及獲利能力配合下所產生的分行營運績效是否如期望中的具有效率或是有待改善的結果。

This paper is intended to explore the efficiency of bank branches throughout Taiwan, the operational performance uses the two-stage Data envelopment analysis (DEA) to evaluate the branch operational performance. The subjects were domestic branches under a financial holding company, during the study period of 2014. The Study will use Data envelopment analysis to evaluate operational efficiency in first stage. In second stage, it will input number of services and depositions to transform financial products and services, to a branch profit and business performance. This will help the branch manager to gain insight into the resources and the profitability of branches. The proposed methods facilitate the decision making by showing whether branches perform at the expected efficiency or exists a need for improvement. An illustrate example is done to show the applicability using data from thirty different branches.
