基于物元可拓的PPP模式在农村水利基础设施建设中的可行性研究

摘要

为了系统地探讨PPP模式在农村水利基础设施建设中的可行性,运用物元可拓理论,提出PPP模式在农村水利基础设施建设可行性多级可拓评价方法.这篇文章基于河北省行唐县农村水利基础设施建设的现状和《中国统计年鉴》的数据确定了经济效益,社会效益,环境效益,可持续发展效益4个一级指标和22个二级指标.而后划分各级效益的等级域,确定各级效益的经典域和节域,建立各级效益指标和效益等级的关联度函数,最终综合考虑各个因素的权重影响,结合物元可拓多级评价方法确定各个一级指标的等级.结果表明:经济效益,社会效益的等级为一般水平,环境效益的等级为高水平;可持续发展效益的等级为较高水平.PPP模式应用到农村水利基础设施建设中可以带来可观的经济效益和社会效益,长久的环境效益和可持续发展效益,从而力证了PPP模式在农村水利基础设施建设中的可行性.%To explore the feasibility of PPP model in rural water infrastructure systematically,the multilevel extension assessment method is proposed to evaluate the feasibility of PPP model in rural water infrastructure based on the theory of matter element extension.According to the current situation of rural water infrastructure in Xingtang county,Hebei province and the China Statistical Yearbook of data,four level indexes and twenty-two secondary indexes are determined;and four level indexes are the economic,social,environmental and sustainable development benefits.Then,classic domains and section domains are determined and function associated with evaluation indexes and evaluation level is established by dividing the evaluation level domains.Finally,with consideration of index weight impact,the evaluation level was determined with the multilevel extension assessment method.The results indicate that economic,social rank is of the general level;the level of environmental benefit is of the high level;the sustainable development benefits is of a higher grade level.The conclusion can be drawn that the application of PPP model is feasible in rural water infrastructure,so as to produce considerable economic,social,environmental and long-term sustainable benefits.
