基于组合评价的长三角城市基础设施投资绩效研究

城市基础设施投资绩效的合理评价是进行科学投资决策的重要依据。为了对长三角25个城市基础设施投资绩效进行客观、合理的评价,建立了基础设施投资绩效评价指标体系,选取2009年截面数据采用组合评价法进行综合评价。该方法首先使用超效率DEA、熵权TOPSIS、因子分析三种方法得出各自结果下的排名,在验证了各评价方法具有一致性的前提下采用模糊Borda综合评价法得出各城市的最终排名。组合评价方法弥补了单一方法的不足,有助于得到更客观合理的评价结果,为有关城市和部门把握基础设施投资绩效和未来决策提供参考。

Research on the Infrastructure Investment Performance of Yangtze River Delta Based on Combination Evaluation Method

Reasonable evaluation of city infrastructure investment performance is an important basis for scientific investment decision. In order to make an objective and reasonable evaluation of infrastructure investment performance for the 25 cities in Yangtze river delta, a set of evaluation index system is established and the sectional data in 2009 is selected for comprehensive evaluation. Firstly, SE-DEA model, entropy weight TOPSIS model and factor analysis model are used to get cities' ranking respectively. Then, Kendall-W correlation is used to verify the coherence of different method and fussy Borda model is applied to get the final evaluation result. The combination evaluation method makes up for the lack of single method and helps to get more objective and reasonable evaluation result, which could provide reference for the government departments to know the level of infrastructure investment performance and to make scientific investment decisions.
