Evaluation Study of Efficiency in Chinese Commercial Banks Based on Fuzzy Combination

Modeling technique of combination evaluation can reduce the degree of information imperfect in complex system. Fuzzy combination method that takes fuzzy theory and combination idea together can make the evaluation of complex system closer to reality. This paper adopt five methods, synthetic index approach, principal component analysis, factor analysis, DEA and information entropy, wholly evaluate and order the efficiency of Chinese commercial banks based on actual Chinese commercial bank data, firstly. Secondly, the author uses nonparametric Spearman order relational coefficient method to test The result is that except for DEA other four evaluation methods are of consistency. Finally, the author establishes fuzzy combination evaluation model, and uses it to wholly evaluate and order the management efficiency of 11 commercial banks, whose result is more scientific and rational.
