金融環境變化使得銀行業經營面臨極大挑戰,種種複雜因素將影響其經營績效,故如何準確地找出影響銀行經營績效的因素為一重要課題。因此,本文透過傳統計量經濟學的迴歸分析、文獻回顧的方式以及專家的實務經驗,找出引響銀行經營績效之關鍵因素,並將因素分別歸為四大構面:股權結構、獲利能力、安全性、總體經濟因素。運用DEMATEL(Decision Making Trial and Evaluation Laboratory, DEMATEL)作為分析方法,將問題予以結構化,並找出其關鍵因素,觀察因素之間的影響路徑。針對要素之間直接關係的有無或因素之間的關聯強度做「定量分析」。再者,選定準則與評量尺度,並對專家訪談,並加以整合問卷,以及多角度的比較分析,找出各因素之間影響銀行經營績效之途徑,進而達到本研究之目的。研究結果顯示,「逾放比率」、「放款利益率」、「營業利益率」、「資產報酬率」、「稅前淨利率」、「股東權益報酬率」、「每股盈餘」為影響銀行經營績效之關鍵因素。本研究的解決方案,具有相當的實用性,可以清楚看出因素間之因果關係,探討銀行之經營策略,來因應變動快速的大環境並解決問題,以供銀行進行經營策略的調整。
Changes in the financial environment make bank face great challenges, It is an important issue how to obtain the determinants of the impact on the bank’s operating performance. In the present study, we employ the regression analysis, literature review and practical experience of specialist to define the factors which are classified into four dimensions: ownership structure, profitability, security and macroeconomic factors. Furthermore, we use the DEMATEL (Decision Making Trial and Evaluation Laboratory, DEMATEL) as the analytical method to catch the structurization of problem and the causual paths among the factors. The empirical evidence shows that the determinants of affecting bank’s operation performance consist of NPL ratio, loan interest rate, operating profit margin, return on assets, earning before tax margin, return on equity and earnings per share. We uncover clearly the causal relationship between the factors. It would offer the business strategy and help the manager to cope with the rapid changes in the environment for the bank.
