Application of Factor Analysis Method to the Evaluation Model of Corporation Competence

ZHANG Rui,LI En,TIAN Peng(School of Management,Shanghai Jiaotong University,Shanghai 200052,China)  
Multi-collinearity,i.e.the lack of independence between variances is a cause to the inaccuracy of regression models,which sets obstacles of statistical methods to evaluation of corporation competence.Through an empirical study,factor analysis is applied to the evaluation of corporation competence.It attempts to identify underlying variables,or factors,that explain the pattern of correlations within a set of observed variables,and to eliminate multi-collinearity.And it helps to extract a few integrated indices from a larger number of variables,thereby decreasing the dimension of established model.The result shows that this method is satisfying in the fact of model interpretability,reliability,etc.
