台灣銀行業之利差影響因素分析
An Analysis of The Determinants of Net Interest Margins of Commercial Banks in Taiwan
摘要
台灣的銀行業因金融自由化、國際化及政府實施金融改革開放政策，使國內銀行業家數及分支機構過多，經營環境面臨激烈的競爭，致存放款利率價格競爭激烈，存放款利率差距縮小，利差管理有深入探討之必要。本研究以台灣地區30家本國銀行為研究對象，研究期間自2000年到2011年共48季的財務資料，來探討台灣銀行業之淨利差影響因素。 本研究以衡量銀行經營績效之CAMELS模型、資產負債表之資金來源與運用的存放款規模及成長性指標、經營管理能力指標及金融機構特殊性指標等財務資料共20個財務比率作為自變數，以淨利差作為應變數，並應用追蹤資料分析法來探討銀行淨利差之影響因素。實證結果發現：(一)流動比率、短期性放款比率、中長期放款比率、定期性存款成長率等變數對淨利差有顯著正向影響。(二)逾放比率、淨值報酬率、金融業隔夜拆款利率、定期性存款比率、短期性放款成長率、投資對總資產比率、逾放備抵呆帳覆蓋率及孳息資產及付息負債比率等變數對淨利差有顯著負向影響。

Due to a sequential financial deregulation, the banking industry in Taiwan has been facing the so called over-banking problem. As a result, the profitability of Taiwan’s commercial banks is getting lower and lower recently. The objective of this study is to utilize the Panel Data Analysis to 30 commercial banks in Taiwan in the periods of 2000/Q1 to 2011/Q4 to analyze factors influencing net interest margins (NIM) of Taiwan’s commercial banks. A total of 20 variables, including the CAMELS model, indicators of the scale and growth of deposits and loans of banks, management capability variables, and some other special indicators, are considered in the NIM model. Results show that, first, the current ratio, ratio of short-term loan and long-term loan, and time deposits growth rate are found to be positively correlated to commercial bank’s NIM. Second, the overdue loan ratio, ROE, overnight federal funds rate, time deposits rate, growth rate of short-term loan, investment to total assets ratio, coverage ratio, and earning assets to interest-bearing debt ratio are found to be significantly negatively related to NIM.
