本研究利用臺灣的資料粗略評估新版巴賽爾資本適足率規範對銀行體系的影響，以作為監管單位修正銀行資本規範之參考。實證結果顯示：當資本比率不足時，銀行會藉由提高放款利率、代換成較低風險資產或減少持有高風險資產等方式以降低影響分母的風險性資產類項目；及以增資、發行合格債券、保留盈餘等方式增加分子之資本類項目。臺灣的銀行整體而言在資本適足率規範提高時資本增加幅度大於資產減少幅度，暗示銀行業雖然會依據資金成本決定資本化方式，但可能更重視資產規模及業務市占率。反映了臺灣金融機構家數過多導致過度競爭的事實，銀行寧願使用較貴的增資方式也不願意以減少資產或縮減放貸業務等方式達到目標資本比率。從銀行調整資本項目的程度也可發現，在僅規範自有資本適足率時銀行使用成本較低的第二、三類資本去填充總資本以達目標資本比率，難以達到增加銀行業資本穩固性的效果，需進一步規範核心資本適足率始有效提高銀行吸收損失的能力。這樣的結果提供監理單位在修改法令規範上的依據：銀行有使用低成本之資本的誘因，為達到總體審慎之風險管理目的，應增訂核心資本適足率規範，並對核心資本不足之銀行採取立即糾正措施。 / In this study, we conducted a rough assessment of the impact of new Basel capital adequacy ratio on Taiwanese banking system as a consultation of regulatory amendment. The empirical results show: when the capital ratio is low, the bank will raise lending rates, reduce lending volume and other risk assets, at the same time raise capital by retaining earnings and issuing qualified bonds. Taiwan's banks in general increased capital greater than reducing risk weighted assets, suggesting that although the banks would follow the pecking order theory of the cost of capital when capitalization, but may pay more attention to asset size and market share. Reflects the phenomenon of excessive competition over the banking system in Taiwan‐banks would rather use more expensive capital than cutting loans to achieve target capital ratio. We also found that, the effectiveness of regulatory interventions intended to raise banks’ ability to absorb losses may be somewhat muted unless such capital requirements mandate the type of capital that must be raised, the banks had the incentives to favor adjustments to tiers 2 and 3 capital (or to the deductions that they make from total capital) over adjustments to tier 1 capital in order to achieve the target capital ratio. As the result, to effectively improve the banks’ ability to absorb losses, the supervisory units should add the requirements of core capital adequacy ratio and take prompt corrective actions when banks exhibit progressively deteriorating capital ratios.
