First, we discuss several theories of risk measures respectively such as theories ofcoherent measures of risk, spectral measures of risk and distortion measures of risk.Within the framework of these theories, we discuss and compare standard deviation,mean absolute deviation, lower partial moment, Ginis difference, VaR, CVaR and soon. We conclude that CVaR is superior to other measures with respect to theoreticalproperties.

从实践和发展的角度出发，围绕客户评级授信、信贷风险测量、信贷风险管理策略三个方面，就如何提高银川市商业银行信贷风险管理水平展开研究，得出以下结论：通过实证分析，银川市商业银行现有的客户评级授信方法具有方法简单、易于推广的优点，但客户评级授信指标体系具有客户分组不细、未考虑行业风险因素、定量指标占比过大、未考虑关联企业风险因素的缺点，应通过细化客户分组，增加行业风险因素指标、合理设定定性指标比重、增加关联企业风险评价指标等措施进行改进；从发展的角度出发，在基于VaR框架和CreditMetrics模型技术的基础上，探讨了银川市商业银行信贷风险分析和度量的方法，给出了采用CreditMetrics模型技术计算单笔贷款、组合贷款VAR值的例子；从五个角度探讨了提高银川市商业银行信贷风险管理能力的策略和手段，包括强化信贷风险内控管理机制、利用信息技术提高信贷风险管理技术水平、综合治理化解不良资产、调整信贷结构、建立以风险控制为核心的信贷文化等对策。

According to Iacoviello and Minetti (2003), this article uses Taiwan data for 1995 first season to 2004 fourth season to check wheter Taiwanese housing market has the credit channel. This article establishes four groups of VAR model. Model (1) including overnight interest rate, GDP, the consumer price index, the house price index, the total bank loans, the bank housing loan. The model (2) replaces bank loan and housing loan; for spread. The model (3) uses Mix to replace the Spread. The model (4) including GDP, the consumer price index, the house price index and uses Mix to replaces overnight interest rate.

摘要 本文用台湾地区1995第一季至2004第四季共40笔季资，验证台湾房屋贷款市场是否存在信用管道，本文首先以ADF单根检定法检定各项变是否为定态数列资料，其次将非定态变数取差分值之后进行VAR模型分析，最后经由估计后VAR模型之参数进行冲击反应分析与预测误差变异数分解，藉以了解当变遇到外冲击时对於台湾房屋贷款市场的影响。
