基于多层主成分分析的企业竞争力评价

Application of Multi-level Principal Component Analysis in Evaluating Enterprise Competitiveness

企业竞争力评价方法一直是理论界和实务界的研究热点,也涌现出众多研究成果,但这些方法在操作过程中都存在一定的局限性。在已有研究成果基础上,将多层主成分分析引入10家样本企业的相关指标数据进行评测,发现该方法有其他方法不具有的优势:较客观地确定指标的权值、有利于进行企业间的比较、能有效解决指标多和样本少的矛盾。

The method of evaluating enterprise competitiveness is a heated topic of research in the field of theory and practice. Earlier studies have produced quite a few methods that are useful but have some limitations. The paper, based on the earlier studies, adopts the method of multi-level principal component analysis to evaluate the relevant indexes of ten sample enterprises and finds out several advantages. This method can determine the value of index objectively, conduct a comparison between enterprises easily, and effectively solve the contradiction between the large number of indexes and the small number of samples.
