我国商业银行贷款定价的最优化模型设计

An Optimal Model Design for Pricing Loans by Our Commercial Banks

随着我国加入WTO,国内金融市场逐步与国际金融市场接轨,国家也逐渐放开对企业贷款利率上限的管制,商业银行可以根据信贷市场需求确定合理的贷款价格,使贷款利率能充分补偿银行所承担的信用风险以确保安全性和赢利性。本文首先阐述目前商业银行贷款定价方法中存在的问题,指出由于我国信贷市场中普遍存在信息不对称这一情况,已经严重影响了商业银行的经营和决策水平;再结合委托-代理框架,套用最优控制理论,给出一个信息不对称时的合理的贷款定价模型;最后针对如何有效提高我国商业银行运作和管理水平给出一些操作性建议。

With China＇s accession into WTO and gradual integration of domestic financial market with international financial market, China has steadily eased the ceiling control over enterprise loan rate. As a result, commercial banks are able to set a reasonable loan price according to market demand to make loan rate fully compensate for the credit risks they have taken to guarantee safety and profitability. The present paper deals with the existing problems in loan pricing and points out that information asymmetry does pre vail in our credit market, which has considerably influenced the operation and decision-？making of commercial banks. Through the framework of trust-agency and optimal cybernetics, a reasonable pricing model for information asymmetry is established. Finally, the paper offers some operative suggestions on how to effectively improve the operation and management of our commercial banks.
