摘要
在国内学者研究的基础上,基于模糊数学理论,建立房地产投资风险模糊综合评价模型;选用层次分析法和熵权法进行组合赋权确定评价指标权重值,引入非线性模糊矩阵合成运算方法,充分考虑被评价指标的非线性特征及其对评价结果的突出影响程度,构建基于非线性模糊综合评价方法的房地产投资风险分析模型。实证分析表明:使用非线性模糊综合评价法误差较小,结果更合理。
Based on domestic studies and the fuzzy mathematics theory, a fuzzy comprehensive evaluation model of real estate investment risk was established, analytic hierarchy process and entropy method were combined to determine the index weight, nonlinear fuzzy matrix synthesis operation method which took into account the nonlinear characteristics of indexes and the prominent effect to evaluation result was introduced to construct a real estate investment risk analysis model on the basis of nonlinear fuzzy comprehensive evaluation method. Finally, the method was employed for empirical analysis and made the quantitative comparison with traditional method, which indicates that the method proposed here was more reasonable.
