台灣利率自由化的演進過程，是採取循序漸進的方式，先由貨幣市場實施，再逐步推及到存放款市場。自1989年利率自由化及1991年政府開放新商業銀行設立以來，台灣銀行業的競爭就進入了白熱化的春秋戰國時代，金融版圖重新調整，產業的競爭有增無減。這期間經過兩次的金融改革，體質較弱的銀行紛紛走向讓售及被併購的命運，尤其是2008年發生金融海嘯，對銀行業的經營更是一大挑戰。觀察近年來銀行業的經營困境，存放款利差持續走低，多數銀行採取價格競爭策略，企業授信市場採用低利削價的手段，造成銀行業獲利率降低，危及銀行健全經營體質。所以本研究從文獻回顧探討影響放款利率定價決定因素，從樣本銀行實務授信政策及放款定價辦法探討影響放款利率定價決定因素，並利用樣本資料從實證模型的估計及檢驗來推估假設變數與企業貸款利率定價之間的具體關係及影響方向與程度，最後將實證結果提供予銀行管理當局擬定授信政策及建立完善放款利率定價模型之參考。 / From money market to deposit and loan markets, the development of interest rate liberalization in Taiwan has been in gradual progress. Since interest-rate liberalization in the year of 1989 and governmental approval on the establishment of new commercial banks in 1991, the competition among banks in Taiwan has become severe. Market shares among banks have thus changed. During the period, the financial market experienced two banking reforms. Banks with relatively weak financial nature have been forced to be sold or merged. Moreover, the financial turmoil in the year of 2008 made the business environment of banking industry even more challengeable. Running business in banking has been more difficult in recent years. Interest rate spread for banks has been narrowing. Most banks have adopted price competition strategies. Such price-cutting policy in commercial loan market has resulted in the deterioration of bank management in the industry. This research reviews study-papers focusing on the factors affecting commercial loan interest rate pricing, using bank A as a sample to review its actual operation of credit policy and loan pricing means. In addition, by adopting technique of empirical model measurement and statistical test on the sample data, the concrete correlation and extent of influence between hypothetical variables and pricing on commercial loan interest rate are also estimated. The aim of this paper is to provide empirical tested results to the banking authorities for their reference when designing fine credit policies and commercial loan pricing model.
