The Evaluation of Multiple Principal Component of Large Scale System and Its Application

大系统综合评价是综合评价的重要内容之一。文章在分析传统的主成分分析在降维效果、权系数等问题的基础上,提出了一种针对大系统综合评价的改进的主成分评价方法———多重主成分评价。在理论分析其合理性的基础上,最后利用商业银行经营绩效的实例验证了这种方法的有效性。

The evaluation of large scale system is one of the important parts of comprehensive evaluations.Firstly, based on analyzing some questions in traditional PCA such as effect of depressed dimension and coefficients, a new improved method called the multiple PCA is pointed out, which solves the evaluation of large scale system specially. On the basis of analyzing its rationality of the multiple PCA theoretically, it tests the validity of this method by taking the example of operation performance of commercial bank.
