固定經(jīng)營期下基于運行績效的PPP項目服務價格形成機制研究

摘要： 本文研究PPP項目價格形成機制、補償機制及其社會效率。首先,分析了招投標制度下固定經(jīng)營期PPP項目服務價格形成機制及其不足。其次,基于成本與運行績效的PPP項目定價規(guī)制及可行性缺口補貼思想,建立模型分析實施機構可觀察PPP項目服務成本時的定價水平和可行性缺口補貼標準;當實施機構無法準確掌握項目公司的運行成本時,通過制度設計誘導社會投資者上報真實的運行成本和運行績效以獲得最大凈現(xiàn)值。分析表明,當PPP項目服務需求彈性較大同時有可行性缺口補貼政策時,政府進行價格規(guī)制時項目凈現(xiàn)值高于不規(guī)制時的凈現(xiàn)值。文章通過實例驗證了成本信息是否可觀察兩種情形下PPP項目的服務價格水平、運行績效、項目投資凈現(xiàn)值及消費者剩余。為了避免PPP項目運行績效下降和社會福利損失,政府應建立科學的監(jiān)督激勵機制,依據(jù)PPP項目服務成本與運行績效的信息確定固定特許經(jīng)營期下項目服務價格和可行性缺口補貼額度。
In this paper, a model is built to research the pricing formation mechanism, compensation mechanism and social efficiency in public project in public private partnership. Firstly, this paper analyzes the service price bidding price principle under the fixed concessionary period and its shortcomings. Secondly, since government constitutes public project controlled price feasibility gap subsidy according to the cost and operational performance of project company,we establish a model to analyze the pricing level and the feasibility gap subsidy standard when implementing agencies can observe the service cost of PPP projects, induce social investors to report the real operating cost and operating performance through system design to obtain the maximum net present value when the implementing agency cannot accurately grasp the operating cost of the project company. The analysis shows that the net present value of a project is higher than that when the government does not regulate price; when the demand for project services is flexible, the contract stipulates to subsidize the feasibility gap of the project company. Some conclusions on PPP mode service price, operational performance, consumer surplus, private enterprise's profits and social efficiency in different cost information and controlled condition are analyzed and verified. For the sake of avoiding the decrease of operational performance and loss of social welfare, government should establish scientific monitoring prompting mechanism,determine the service price and feasibility gap subsidy amount based on the information of supply cost and operational performance.
