基于灰色系统理论的商业银行竞争力评价模型

建立了市场占有能力、盈利性等4方面的竞争力评价指标体系，引入灰色系统理论，建立了基于灰色系统理论的商业银行竞争力评价模型，该模型具有如下主要特点：一是构建理想银行。计算被评价银行与理想银行之间的关联度，其关联度大小的排序即银行竞争力强弱的顺序，二是选取典型银行，进行了主成分分析和灰色关联优势分析，通过综合关联度的计算得到各指标对综合得分的影响程度，解决了现有研究中对指标权重确定主观性太强的缺点。

Competitiveness Appraisal Model Based on Gray System Theory

An evaluation index system of competitiveness of commercial banks is set up, including market power, profitability etc. Then a competitiveness appraisal model for commercial banks is presented based on gray system theory. The first innovation of the model lies in building ideal commercial banks, calculating the relational extend between the appraisal commercial banks and ideal commercial banks. Secondly, the representative bank is chosen, by applying, principal component analysis and gray relational advantage analysis, to find the extent between every index and synthetically score. By means of computing synthesis relational extent, index weights are obtained, avoiding the more subjective weakness of former researches.
