【摘要】：针对PPP污水处理项目特许期内污水处理价格受多种因素影响而不确定的问题,从实现项目的社会效益最大化以及三个主要参与方(政府、私人投资者和消费者)利益均衡的角度,本文构建了系统动力学(SD)和多目标规划(MOP)耦合模型(SD-MOP),研究特许期内污水处理价格的动态调整机制。利用MOP模型求解三方满意的最优污水处理定价方案;SD模型模拟特许期内最优定价方案下PPP项目外部以及内部环境的变化,为MOP模型提供动态参数,从而获得调价方案。并以某市PPP模式下的排水企业为例,运用所构建的方法分析其服务价格以及居民实际支付价格合适的调整时机以及调整幅度,旨在建立一套科学合理的方法,为管理者和研究人员对PPP项目的主动管理提供理论依据和参考。
[Abstract]:In order to solve the problem that the price of PPP sewage treatment project is influenced by many factors during the concession period of PPP sewage treatment project, from realizing the maximum social benefit of the project and three main participants (the government, the government, the government, the government, the government, the government, The balance of interests between private investors and consumers, In this paper, the SD-MOP coupling model of system dynamics and multi-objective programming (MOP) is constructed to study the dynamic adjustment mechanism of sewage treatment price during the concession period. The SD model is simulated by using MOP model to solve the optimal sewage treatment pricing scheme. The change of the external and internal environment of PPP project under the optimal pricing scheme during the concession period, This paper provides dynamic parameters for MOP model and obtains price adjustment scheme. Taking a drainage enterprise under PPP mode of a certain city as an example, this paper analyzes the appropriate time and range of adjustment of service price and residents' actual payment price by using the constructed method. The purpose of this paper is to establish a set of scientific and reasonable methods to provide theoretical basis and reference for managers and researchers to actively manage PPP projects.
