    Abstract: 為了加入世界貿易組織，台灣早已自80年代逐步進行金融自由化的工作：早在1983年政府就擴大存放款利差，1984年允許銀行根據其個別情況制定基本放款利率並放寬本國銀行設立分行的家數與條件。然而金融自由化最重大的里程碑則是在1989年7月財政部修訂銀行法，開放新銀行設立並解除利率管制，自此之後台灣才真正成為金融自由化的國家。
    本研究針對1986年到2002年的本國銀行，採用資料包絡分析法計算效率值，旨在探討台灣銀行業在開放新銀行設立前後的效率與生產力變動情形。不同於其他研究僅以年度為基礎來計算相對效率值，本研究使用「大邊界」的觀念建構出單一效率邊界，更能顯示出在一致的比較基礎上效率變動的趨勢。本研究的主要結果如下：
    1.銀行業全體與開放前既存之舊銀行，在開放前的效率值均顯著大於開放後。至於開放後新舊銀行效率的比較，新銀行的整體技術效率與規模效率較高，舊銀行則在純技術效率上領先新銀行，但檢定結果僅有規模效率一項為顯著。
    2.金控子銀行的效率值較非金控子銀行為高，顯示金控公司會挑選表現好的銀行作為合作夥伴。
    3.在生產力分析部分，舊銀行開放後的總生產力仍小於開放前，儘管舊銀行在開放後的各項經營效率變動較開放前高，但因技術的大幅衰退以致整體生產力仍呈現衰退現象。顯示舊銀行雖然在效率上有所改善，但對於營運上的創新仍太過保守。
    4.在Tobit迴歸分析的部分，股東權益報酬率、資產規模、流動準備率和效率值的關係為正向；分行家數、可控制費用、催收款比率和效率值的關係則為負向。

    關鍵詞：銀行業、效率分析、資料包絡分析法、解除管制
    In order to join World Trade Organization, Taiwan has been gradually liberating its banking industry since 1980s. In 1983 Taiwan augmented the interest difference between loans and savings in banking industry. In 1984 Taiwan allowed a bank to set its own basic interest rate of loans base on business difference and reduced the restriction of setting up the new branches. The biggest leap was in 1989, Taiwan passed the new banking law which deregulated the banking industry. The new law opened the market for the new entrants and abandoned the interest regulation.
    The purpose of this research is to examine the efficiency and productivity changes before and after deregulation of Taiwan’s banking industry. This research applies Data Envelopment Analysis (DEA) approach to measure efficiency scores. The data include most of the domestic banks in Taiwan from 1986 to 2002. Unlike other research use yearly basis to measure relative efficiency difference, this research constructs a single efficiency frontier, grand frontier, to measure the trends of efficiency changes. The major findings of this research as follows.
    1. The statistical results of the full sample exhibit that the efficiency measures before deregulation are statistically significant greater than that of after deregulation. Although the new entrants exhibit higher efficiency scores in total technical efficiency and scale efficiency than incumbents after deregulation, however, only scale efficiency indicates statistically significant level. Incumbents exhibit a higher pure technical efficiency than the new entrants after deregulation.
    2. Banks that joined the financial holding company exhibit higher efficient scores than those of do not join the financial holding company.
    3. The total factor productivity denotes a regress after deregulation. The major factor of productivity regress is due to technology decrease. However, the efficiency change of incumbent banks exhibits a significant increase after deregulation. The finding suggests that although the incumbent banks have significant improvements in efficiency, they are still too conservative in innovations.
    4. The Tobit regression suggests that return on equity (ROE), total assets, and current-reserve ratio have a positive effect on efficiency measures; however, the number of branches, controllable expenses, and bad debt ratio have a negative effect on efficiency measures.
