本篇論文試圖從銀行面對國際放款風險之論點，並應用 Acharya, Hasan, and Saunders (2006)與 Diamond (1984)對於銀行避險方法所持的不同觀點，導入具有能夠評估市場價值(market value)之Black and Scholes (1973)選擇權評價方法，利用比較靜態分析來解釋放款資金面對銀行風險及資本管制下，將會集中於國內放款市場或是分散在國外放款市場。

利用上述研究方法證明出當銀行面對相對高的資本管制時，放款行為將會分散於國外市場，相反的，如果銀行欲追求高風險高收入的放款時，反而會集中放款資金在較熟悉的國內市場，本論文的結果可建議一國若欲將資金留在國內，過多的干預銀行放款行為將會達到反效果。

This thesis uses an option-based model to examine the relationships among capital regulation, bank risk, and the optimal international lending determination.  An increase in the capital-to-deposits ratio decreases the bank’s domestic lending and increases foreign lending when the bank realizes a relatively less risky state of the world.  An increase in the bank’s risk-taking incentive increases its domestic lending and decreases foreign lending when the bank realizes a relatively more risky state.  Our findings provide alternative explanations concerning the effect of capital regulation on lending diversification and the effect of risk-taking incentive on lending focus.
