本論文主要利用Bresnahan(1982)加碼檢定法估計台灣地區本國銀行及外商銀行的市場力。研究期間為民國八十九年一月至九十四年十二月月資料進行實證研究，估計的參數為價格加碼的部分。研究結果顯示，外商銀行的不完全競爭程度高於本國銀行。當本國銀行進一步分為公營與民營銀行，其估計結果顯示，兩者間的市場結構趨向完全競爭。 This thesis applies the technique suggested by Bresnahan(1982) to estimate the market power of the domestic banks and foreign banks operated in Taiwan area. Using monthly data covering the period of 2000 and 2005, the estimated parameter representing the price markup have shown that the foreign banks is operated within a imperfect competitive market than those of the domestic banks. When the domestic banks are separated further more into the public owned and private owned, the pooled estimates remain the same.
