摘　　要：文章用因子分析法攫取企业的绩效因子,并以各因子的方差贡献率与该因子的得分相乘后求和计算出各公司的综合绩效,然后分析了公司能力因子、综合绩效与多元化程度之间的关系。研究发现,无论从多元化的事前影响因素还是从多元化的经济后果上看,多元化都与企业绩效负相关,即多元化损害企业绩效,绩优企业的多元化程度较低。The paper extracts corporate ability factors by principal component analysis and measures comprehensive performance by multiplying each principal component eigenvalue of variance and its component score, and then analyzes the relationship among corporate ability factors, ROA, comprehensive performance and degree of diversification. The results show that degree of diversification is negatively with finn performance significantly from view of ex ante determinants or economic effects of diversification. Therefore, diversification destroys finn performance. The higher of firm performance is, the lower of the degree of diversification is.
