英國經濟學人雜誌 ( 2000/11/11 )、美國紐約時報 ( 2000/12/5 )、美國商業周刊 ( 2000/12/11 ) 等媒體均報導台灣銀行業的逾期放款比率節節昇高，本土性金融危機即將發生，外國媒體雖然有可能是其引用偏差的數據或是誇大其辭的結果，但台灣整體金融體質不健全，經營效率日益下降，卻是不爭的事實。
放款為銀行主要的收入來源，但是每一筆放款皆有可能成為逾放款。逾放款為非意欲產出，導致銀行的資產品質及績效下降，本研究探討逾放款對銀行效率的影響。由於逾放款為非意欲產出，一般的隨機邊界法或資料包絡法無法應用，本研究採用投入距離函數法估計效率邊界，據以取得逾放款之影子價格，影子價格即為銀行解決逾放款問題最高願意付出的邊際成本。研究結果顯現：新銀行較舊銀行願意付出較高的成本解決逾放款問題，而公營銀行處理不良放款的意願較民營銀行為高；此外，新銀行在處理逾放款所願意付出的成本隨不同年度則愈益減少，而舊銀行則呈現相反的現象，隨年度愈增。值得一提的是就台灣本國銀行的技術效率表現而言，尚有34.57% 改善空間。

In Economist (11/11/200), New York Time (12/5/2000), Business Week (12/11/2000) and other news media, they have reported that the (share or ratio) of banks’ nonperforming loans in Taiwan has risen, and that it is likely that a financial crisis will happen in the island. The reports and observations of these foreign news media may be derived from some unorthodox data, and exaggerate the outcome. However, it is undeniable fact that the financial system in Taiwan is not perfectly sounded and that the banks often operate inefficiently.
This study tries to investigate how non-performing loans (NPL) affect Taiwanese commercial banks. We employ the input distance function approach to find the frontier of production possibility set and then apply the envelope theorem to calculate the shadow prices of NPL. The shadow price of NPL is the marginal cost of reducing NPL when banks are operating on the production frontier. Empirical results show that public banks have to spend more resources than private banks to cut NPL and both types of banks follow the similar trend through time. Compared to those established before deregulation, banks established after deregulation need almost 2.5 times more resources to reduce one unit of NPL. The marginal costs of reducing NPL for banks established before and after deregulation appear reverse trends during 1999-2001. Furthermore, Taiwanese commercial banks in average could increase their technical efficiencies by 34.57 percent provided that all banks operated on the production frontier.
