臺灣銀行市場自1990年代以來經歷了一個大規模的變動，包含經營條件的改變、亞洲金融風暴、外在的競爭、法令的鬆綁與金融改革等皆給銀行體系帶來了前所未有的衝擊。本研究主要以非結構性Panzar–Rosse檢定法來檢定臺灣銀行產業的市場結構，配合追縱資料（Panel data）對1996-2007年的臺灣銀行界月資料進行分析。目的在求得不同情況與條件下代表市場結構的H值，另檢視個別事件的發生對臺灣銀行市場的競爭程度之影響，並衡量臺灣銀行產業逐年的變化與影響變化的因素。本文另針對Panzar–Rosse檢定法所衡量之收益係以單純銀行總收入或銀行總收入除以總資產同時進行檢定，發現僅使用總收入為應變數時，存在R-square過高的情形，若將總收入除以總資產，則可消弭R-square過高的結果且不影響結論。實證結果發現臺灣銀行市場除1999、2004與2007年外，大體上維持著獨佔性競爭的狀態。且隨著時間的演進，代表競爭程度的H值上升至某程度後逐漸減少，顯示臺灣銀行產業過度競爭的問題獲得抒緩。另本文使用月資料的檢測能針對過往文獻所無法進行的短期事件影響程度進行分析檢測，亞洲金融風暴並未給臺灣的金融體系造成立即的影響；2000年政黨輪替後的金融革新與自由化使得臺灣銀行產業的競爭程度提高；一次金改藉著消除銀行的不良資產與逾期放款，提升了競爭程度；而二次金改雖然半途而廢，仍對臺灣的銀行產業造成影響。

Banking market has experienced a large-scale changes and events with operating conditions. Asian financial crisis, external competition, deregulation and financial reforms brought an unprecedented impact to Taiwan’s banking system since 1990s. This study used non-structural Panzar–Rosse methodology to examine Taiwan’s market structure with monthly panel data over the period 1996 to 2007. The purpose of this study is to estimate the ‘H-statistic’ which represent market structure. Meanwhile, this research examined the impacts of individual event, factors and yearly changes on competition degrees in Taiwan’s banking system. The results indicated that Taiwan’s market structure is monopolistic competition except for 1999、2004 and 2007. Competition degree increased from 1996 to 2004. Subsequently, this paper examines effects of short accidents by monthly data that previous literatures did not test. Therefore, Asian financial crisis was not affect Taiwan’s financial system immediately. Restructuring, deregulation and financial reforms improved the competition degree.
