由於銀行準備金比率為受貨幣政策機制影響的重要變數之一，但目前並無針對台灣進行的實證研究，因此本文的研究重點著重於探討台灣的銀行準備金比率受不同變數因子的影響。本研究採用的解釋變數有央行的重貼現利率、製造業的工業生產指數、加權法定準備率、壞帳比率、存放款利差、3年期政府公債殖利率、落後一期拆款利率及代表拆款市場重大變革時點的虛擬變數。樣本主要採用由中央銀行統計資料庫及 TEJ 資料庫所蒐集之月資料，採用期間為 1995 年 6 月至 2014 年 7 月，並且使用 OLS 模型進行實證分析。實證結果發現，製造業的工業生產指數及落後一期拆款利率為負向顯著，而 1995年8月的虛擬變數為正向顯著。 / The purpose of the study was focused on the impact of Taiwan banks' reserve ratio by different variable factors, since the banks' reserve ratio was one of the important variables affected by monetary policy mechanism, however, there was no empirical research carried out for Taiwan currently.
