本文透過兩期、兩階段的選擇權評價模式來分析,在資本管制、資訊不對稱、電子金融涉入程度與存款機構之最適存款利率之關係。本文認為電子金融不只是一項科技,同時也是種策略,於本文模型分析結果顯示,一旦我們將電子金融視為一項科技時,當存款機構採行存、放款互補策略時,則存款機構可以利用網路來取代銀行之實體分行。而一旦我們將電子金融視為一項策略時,當存款機構採行電子金融互補策略(替代)時,則資本管制與資訊不稱的程度提高,將會為存款機構發展電子金融提供誘因(無誘因)。因此,本文研究結果可以為電子金融提供另一種的解釋角度,更提供存款機構在發展電子金融策略時做為參考。
We use a two-stage, two-period option-based model to study how capital regulation, asymmetric information, strategic e-finance and the depository financial intermediary’s optimal deposit rate relate to one another. We found that e-finance can be treated as not only a technology but also a strategy. Once we treated that e-finance is a technology, we found that the depository financial intermediary can use the Internet to supplant its branches under the strategic complements in the strategic asset-liability management. Once we treated that e-finance is a strategy, we found that an increase in the capital requirements and asymmetrical information provide incentives for the intermediary’s developing e-finance under the strategic e-finance complements. Since our findings provide an alternative explanation for e-finance literature.
