基于IFS与TOPSIS的城市基础设施PPP项目融资风险评价

Financing Risk Evaluation of Urban Infrastructure Project Based on PPP Mode Based on IFS and TOPSIS Method

针对PPP模式下城市基础设施项目融资风险评价问题,提出了运用直觉模糊集(IFS)与逼近理想解法(TOPSIS)相结合的城市基础设施项目融资风险评价方法。首先应用直觉模糊思想构建城市基础设施PPP项目的融资风险评价指标集,以保证评价指标对于项目信息表达的完整性;然后结合TOPSIS法确定方案贴近度,对各方案进行排序以筛选出最优方案;最后应用该方法对某市的5处公共地下车库项目融资风险进行评价。实证研究表明:该风险评价实现了"客观性""全面性"和"适用性",是科学合理的,对于PPP模式下的城市基础设施项目融资风险评价能够提供一定的帮助。

In order to evaluate the financing risk of urban infrastructure project based on PPP mode,putting forward the method of intuitionistic fuzzy sets(IFS)and TOPSIS.Firstly,building financing risk evaluation index set of urban infrastructure project based on PPP mode with the application of intuitionistic fuzzy ideas,to ensure the integrity of the evaluation index information.T h e n determining the solution degreecombined with TOPSIS method,and sorting the solutions for the best option screening.Finally applying the method to evaluate the financing risk of five public underground garage of a city.The empirical study shows that the risk assessment implements“objectivity”“comprehensive”and“suitability”.The model is scientific and reasonable,and it can offer help to the urban infrastructure project based on PPP mode of financing risk evaluation research.
