【摘要】：目前关于综合评价方法的研究已经取得丰硕成果,然而由于分析视角的多样性,方法原理的差异性,人为判断的主观性等,各种不同的方法所得出的结论往往不相同。为了解决评价结论不一致问题,组合评价方法成为了学者们关注的焦点。基于此,首先对已有的关于组合评价方法的研究进行细致梳理,为开发新的组合评价方法奠定基础。然后,针对组合评价方法的特殊性以及评价数据为二维且分布不均的情况,提出了一种专门用于解决组合评价问题的信息集结方法,即组合(CW)算子。该方法能同时考虑单一方法的同质性特征和异质性特征,并在系统聚类分组的基础上进行二次加权,有利于得出更加稳健的评价结论。其次,为了进一步验证该方法在实践中的有效性,将其应用于2015年16家上市商业银行的绩效评价,将简单线性加权法、灰色关联法、熵值法、理想点法、改进理想点法、模糊综合评价法和主成分分析法这7种方法进行组合得出相应结论。最后,分别从评价方法个数和被评价对象个数两个视角进行测度,对基于CW算子的组合评价方法进行稳定性分析。并与平均值法进行对比分析,结果表明基于CW算子的组合评价方法比平均值法更具稳定性。
[Abstract]:At present, the research on the comprehensive evaluation method has achieved fruitful results. However, due to the diversity of the analytical perspective, the difference of the principle of the method, the subjectivity of man-made judgment and so on, the conclusions obtained by different methods are often different. In order to solve the problem of inconsistent evaluation conclusion, combinatorial evaluation method has become the focus of scholars. Based on this, the existing research on combinatorial evaluation methods is carefully combed in order to lay a foundation for the development of new combinatorial evaluation methods. Then, in view of the particularity of the combinatorial evaluation method and the two-dimensional and uneven distribution of the evaluation data, this paper proposes an information aggregation method which is specially used to solve the combinatorial evaluation problem, that is, the combinatorial (CW) operator. This method can take into account the homogeneity and heterogeneity of a single method at the same time, and weighted twice on the basis of systematic cluster grouping, which is helpful to draw a more robust evaluation conclusion. Secondly, in order to further verify the effectiveness of the method in practice, it is applied to the performance evaluation of 16 listed commercial banks in 2015. The simple linear weighting method, grey correlation method, entropy method, ideal point method and improved ideal point method are applied to the performance evaluation of 16 listed commercial banks in 2015. Fuzzy comprehensive evaluation method and principal component analysis method are combined to get the corresponding conclusion. Finally, from the two perspectives of the number of evaluation methods and the number of evaluated objects, the stability analysis of the combinatorial evaluation method based on CW operator is carried out. Compared with the average method, the results show that the combination evaluation method based on CW operator is more stable than the average method.
