Secondly , the thesis bring ups to make use of mathematics clustering analysis method , combine with analysis the accident occur rate of each occupation ( business enterprise ) , the death rate of employment injury , the severely wounded rate of employment injury , the slight wound rate of employment injury , the death rate of occupational disease , the occur rate of occupational disease and the circumstance of employment injury overhead and so on , to classify the risk grades of occupation ( enterprise ) . according to the clustering consequence , the grade differential rate of the 其次，论文运用数学聚类分析方法，结合各行业（企业）的事故发生率、工伤死亡率、工伤重伤率、工伤轻伤率、职业病死亡率、职业病病伤率以及工伤费用支出情况等指标进行行业（企业）风险等级分类。根据分类结果，合理确定各行业风险等级差别费率。再次，论文通过对国内外现行工伤保险费率浮动方法的研究，提出了结合企业千人死亡率、千人重伤率、千人轻伤率和支收率指标来确定企业费率浮动的方法。
The first section is concerned with a brief description of the content and methods of evaluation . the second section is concerned with rifr evaluation of actual developing projects : ( 1 ) their absolute magnitudes and relative order of four risks based on sensitivity analysis of risk index ; and ( 2 ) the comprehensive risk grade evaluation of rifr through integrating fuzzy subordinate function with fuzzy integrative evaluation method 首先概要地介绍了衡量项目投融资区域风险的内容与方法，接着研究项目投融资风险评价：通过选取风险变量和评价指标，结合敏感度分析进行风险大小排序，再进一步结合模糊隶属度函数和模糊评价法的运用进行项目投融资区域风险的风险等级判定。
On the other hand , that risk matrix is analysised and the order of risk degree in every process is given by the way of principle component analyses . the process is found out whose risk degree is great , so this can point out a direction to those practical works . finally , there are some diagrams ( risks distributing ) and a few of advices ( the ways by which risks are evaded ) 为便于对风险源进行定量的分析，本研究采用了基于模糊数学的基本方法，将风险源的风险等级转化为可对其进行数值分析的模糊风险值；并应用主成分分析法，对风险矩阵进行了分析，对各个过程的风险度进行了排序；找出了风险度较大的过程，为更好地指导实际工作创造了条件。
This study will help banks build theoretic and methodological foundation to control the default risk and prepayment risk at the origination of residential mortgage loans , and providing foundation for bank evaluating credit risk rating of residential mortgage loans . the mortgage loan sample data is from some commercial bank during the period from the year 2000 to the year 2004 在这个背景下,本文以个人住房抵押贷款违约风险和提前还款风险的影响因素为研究对象,试图识别现阶段我国个人住房抵押贷款违约风险和提前还款风险的主要影响因素,并为商业银行在个人住房抵押贷款发放之初就能有效的管理违约风险和提前还款风险奠定理论和方法的基础,并为银行对住房抵押贷款风险等级的评估提供依据。
