摘要
对上市公司的经营绩效进行比较分析时,传统方法是先对指标进行因子分析,然后根据因子得分再对样本进行聚类分析.本文先对样本进行聚类分析,然后再对每一个类采用传统方法进行分析.通过对A股市场719家上市公司经营绩效的实证分析表明:改进方法很好的解决了传统方法信息流失的问题,从而使分析结果更加符合市场预期.
When dealing with practical problems based on the factor and cluster analysis, the tradition-al method is first to do factor analysis, and then to do cluster analysis according to the factor scores.

Taking the business efficiency of 719 public companies in A store market for an example. The results show that our new method performs excellent without lost information.
