Bidding is widely introduced to the market of construction,but the method of specialist evaluation,which is usually applied to tender evaluation,is subjective and neglects the correlativities of the evaluation indexes.In this paper,the principal component analysis（PCA） is applied to tender evaluation and make a example to explain rationality and practicability of model,We compute data by SPSS. 主成分分析 评标 评价 模型 principal component analysis tender evaluation evaluate Model F224 2005-01-01 2021-04-01 S2
