分析结果表明信用风险一方面受非系统性基本因素的影响，如公司资产价值、信用状况、违约概率以及相关性等，另外一方面也受到系统性宏观经济因素的影响，如利率、经济周期和行业因素等。其次是研究了信用风险的量化管理问题。具体方法是通过比较分析四种具有代表性的信用风险度量模型，包括CreditMetrics、CredirRisk+、KMV以及CreditPortfolioView等，目的是找到信用风险量化方法的统一框架，为度量信用风险建立一个合适的标准。

Risk factors of mortality by univariate analysis were: outborn babies, resuscitation before admission, first born baby, low pH, high oxygen index, high alveolar- arterial oxygen tension gradient (AaDO2) at admission, high Of and AaDO2 at 2 hours after admission, shock, pneumothorax, asphyxia, pulmonary hemorrhage, persistent pulmonary hypertension of newborn, and renal failure. Logistic regression analysis showed asphyxia, pneumothorax and PPHN are the most important risk factors of mortality in MAS. How to diminish these events is the key point for reducing the mortality rate of MAS.
