【摘要】：PPP模式是公共部门和私人部门针对特定公共项目,以签订特许权协议的方式所建立的长期互利的制度化合作关系,充分发挥公私双方各自优势,提高公共产品和服务的建设运营效率,是一种以利益相关者多赢为合作理念的现代融资模式。PPP模式已在我国基础设施领域发挥了不可或缺的作用,对缓解政府部门资金压力、满足社会对公共产品和服务的需求具有重要意义,但自2008年起私人部门投资额大幅下降,产生该现象的主要原因是PPP项目未能达到预期效果,其建设和运营收效参差不齐。究其根本,各自效用未能有效实现,导致参与方合作化程度低,更注重自身效用而忽视其他参与方利益,最终造成合作效率降低达不到预期目的。在此背景下,本文结合实际经验背景对PPP项目合作效率进行系统研究,从PPP项目的根本目标出发,即最大化核心利益相关者——政府、私人部门以及社会公众的总效用,明确三方价值取向,通过问卷调查与统计分析建立基于三方满意的PPP项目合作效率灰色评价模型,探寻影响合作化程度的关键要素,在此基础上将各要素纳入到统一的框架进行权衡分析,提出解决措施,最大化三方总效用,从而提高合作化程度,引导项目的后续成功运营。以北京地铁4号线为背景展开实证分析,对PPP项目全生命周期的合作效率进行了研究,验证本文所提出的评价模型的有效性和适用性。
[Abstract]:The PPP model is a long-term, mutually beneficial and institutionalized cooperative relationship between the public sector and the private sector for a specific public project and through the signing of a concession agreement, giving full play to the respective advantages of both the public and private sectors. To improve the efficiency of construction and operation of public goods and services is a modern financing mode based on the concept of multi-win cooperation among stakeholders. PPP model has played an indispensable role in the field of infrastructure in China, which can alleviate the pressure on government funds. It is of great significance to meet the social demand for public goods and services, but the private sector investment has dropped sharply since 2008. The main reason for this phenomenon is that the PPP project has not achieved the expected results, and its construction and operation results are uneven. At its root, their respective utility can not be realized effectively, which leads to the low degree of cooperation between the participants, pays more attention to their own utility and neglects the interests of other participants, resulting in the reduction of the efficiency of cooperation to achieve the desired purpose. In this context, this paper makes a systematic study on the efficiency of PPP project cooperation based on the practical experience, starting from the fundamental goal of the PPP project, that is, maximizing the total utility of the core stakeholders-the government, the private sector and the public. Through the questionnaire survey and statistical analysis, a grey evaluation model of PPP project cooperation efficiency based on tripartite satisfaction is established, and the key factors affecting the degree of cooperation are explored. On this basis, the elements are brought into the unified framework for tradeoff analysis, and the solutions are put forward to maximize the total utility of the three parties, so as to improve the degree of cooperation and guide the successful operation of the project. Based on the empirical analysis of Beijing Metro Line 4, this paper studies the cooperation efficiency of the whole life cycle of PPP project, and verifies the validity and applicability of the evaluation model proposed in this paper.
