公共基础设施社会效益组合评价--以天津市为例

Combination Evaluation on the Social Benefit of Urban Public Infrastructure:A Case Study of Tianjin

在构建公共基础设施社会效益评价指标体系的基础上,运用层次分析法、熵权法、灰色关联评价法和主成分分析法对天津市2000-2014年公共基础设施系统社会效益进行了综合评价。在通过Kendall-W系数法一致性检验前提下,运用拉开档次组合评价模型对单一方法的评价结果进行组合评价。最后采用Spearman等级相关系数对组合评价结果的科学性进行事后检验,得到了2000-2014年天津市公共基础设施社会效益的评价值。

On the basis of establishing social benefit evaluation system of urban public infrastructure, the methods of analytic hierarchy process, entropy weight method, grey correlation analysis and principal component analysis were used to evaluate the social benefits of public infrastructure system from 2000 to 2014 in Tianjin. In the premise of the consistency check of the W-Kendall coefficient method, the combined evaluation model was used to evaluate the results of the single method. In the end, the Spearman rank correlation coefficient was used to examine the scientific performance of the combined evaluation results, and the evaluation values of the social benefits of public infrastructure in Tianjin city from 2000 to 2014 were obtained.
