摘要
采用因子分析法,对现有高速公路投资绩效评价指标体系中的24个评价指标进行降维,提炼出6个公共因子,构建了新的评价指标体系,以哈大高速为例,利用因子分析模型得出该高速公路在各个公共因子上的得分,并应用综合评分模型计算出该高速公路的综合得分,实验结果表明,该方法能较好地应用在高速公路投资绩效评价中。
First,6 common factors are extracted by using factor analysis to reduce the dimension of 24 evaluation indexes which are selected from the existing expressway investment performance evaluation index system,so as to construct a new evaluation index system,the scores of the highway in each common factor are got by factor analysis model,the comprehensive score is calculated by comprehensive score model as the example of Ha-Da highway. The experimental results show that this method can be applied in the evaluation of expressway investment performance.
