摘要:为了正确评价综合国力,提出主成分理想点法.先利用主成分分析降维,得到各个国家关于少数几个综合变量的得分,然后用每个主成分的贡献率加权,得到加权决策矩阵,再使用理想点法进行评价.对世界11个重要国家,选用25个评价指标进行评价.结果表明主成分理想点法克服了单纯理想点法计算复杂、需要确定权数的不足.

关键词: 综合国力, 主成分, 理想点法, 评价

Abstract: In order to evaluate the comprehensive national strength correctly,PCA-TOPSIS is given.Firstly,PCA is used to reduce dimensionality and get the scores of the countries related to a few aggregate variables;Then,the contribution rate of each principal component is used to be weighted and get the weighting decision-making matrix;Finally,TOPSIS is used for evaluation.For 11 important counties in the world,25 evaluation indexes are selected and used for evaluation.The results show that the method overcomes the deficiencies of the simple TOPSIS characterized by the computational complexity and necessity of determining the weights.

Key words: comprehensive national strength, principal component, ideal point method, evaluation
