基于二型模糊理论的中国金融安全指数构建

Establishment of China Financial Security Index Based on Type-2 Fuzzy Theory

中国金融安全指数依赖于指标的选取和合成方法。指标不同,合成方法不同,一般年度指数会不同,有的年份甚至差别会很大,也就是说金融安全指数是不确定的。选取三篇文献中利用不同指标体系和不同方法合成的指数,然后利用二型模糊理论将它们融合成一个新的中国金融安全指数。由于二型模糊理论具有很强的处理不确定性的能力,所以由二型模糊理论融合得到的中国金融安全指数更符合中国的实际情况,实际分析的结果也证实了这一点,因而可以更好地用来反映和评价中国的金融安全状况。

China Financial Security Index （CFSI） depends on the selecting of components and estimating methods. Different methods and components cause different index, a big difference means CFSI is uncertain. This study combines indices from three papers with the type-2 fuzzy theory to make a new CFSI. The analysis results prove that the new CFSI is more suited to realities in China because of the excellent competence of type-2 fuzzy sets in dealing with uncertainty. Therefore, the new CFSI can evaluate and reflect the real trend of Chinese financial security better.
