鉴于公共文化 PPP 项目收益性弱、对私人部门吸引力不足的特点,将私人部门公平偏好引入公共文化 PPP 项目的政府补偿机制设计,构建了以政府为主导的两阶段公私 Stackelberg 博弈模型。 以柳州某文化广场 PPP 项目为例分析了私人部门公平偏好对其初始投资决策、最优投资决策及政府补偿的影响。结果表明:博弈的第一阶段中政府初步许诺的运营期补偿力度较小,私人部门公平偏好与其初始决策投资呈正比;第二阶段确定补偿力度时,政府承诺收入率与私人部门期望收入率之差超过其参照点时,若私人部门公平偏好越高,要求政府最优运营期补偿力度越大,项目最优投资规模亦越大。研究结果可为公共文化 PPP 项目的补偿设计提供理论依据。  相似文献

契约参照点理论以合同为参照点给出解释承包人履约行为选择的新逻辑,但受到合同参照点效应影响的承包人履约行为的类型及表现形式尚不明确,亟需厘清承包人履约行为的结构维度并进行量化。首先,借鉴已有的承包人履约行为的测量题项,并对相似概念的测量题项进行情境化处理构建承包人履约行为测量的初始维度和量表。然后,通过273份问卷调查数据定量分析确定了承包人履约行为的最终构成维度和量表。研究表明,建设项目承包人履约行为的构念是由字面履约行为、尽善履约行为和机会主义行为等三维二阶因子构成。其中,字面履约行为是最常见的形式,其次是尽善履约行为;字面履约行为维度包含正确履行、充分完成及达到绩效目标等三个因子;尽善履约行为体现在自愿利他、主动控制风险、协同互助和弥补合同漏洞等四个方面;而机会主义行为由隐瞒信息、未完成承诺、逃避非正式协议和利用合同漏洞等四个子维度构成。该量表开发后,可为建设项目承包人履约行为的研究提供完整分析框架并对建设项目履约管理研究提供技术支持。  相似文献

为解释以往关于信任对项目绩效正向或负向影响的研究分歧,以 PPP 项目为背景,构建以信任(能力信任和善意信任)为自变量、项目绩效为因变量、合作行为(角色内行为和角色外行为)作为中介变量的理论模型。通过结构方程模型分析 286 份有效问卷,结果表明:能力信任和善意信任对 PPP 项目绩效起正向促进作用,角色内行为和角色外行为对 PPP项目绩效起正向促进作用。同时,角色内行为和角色外行为在能力信任、善意信任与 PPP 项目绩效间均发挥部分中介作用。研究结果有助于深入理解中国 PPP 情境下不同维度信任对项目绩效的影响,也为 PPP 项目实践中面临的绩效低下问题提供了管理建议。  相似文献

Project participants, through experience, have an initial perception and predisposition towards risk and the types of risks they are willing and able to undertake. This is equally true for parties interested in public–private partnership (PPP) projects. These initial positions have been registered for the major Greek PPP market stakeholders potentially involved in a PPP arrangement through a survey covering all candidate construction companies, interested financing institutes and a number of public sector entities to be involved in PPPs. Findings revealed that stakeholders were, for the majority of risks identified, in agreement as to preferred risk allocation. Risk allocation preferences for construction companies were compared with similar findings for the UK, a mature PPP market, indicating a possible learning/maturing process based on the particular country background. Conclusions add to other surveys carried out on the subject and should enable public sector clients to establish a more efficient framework for risk allocation, thus reducing negotiations prior to contract award and minimizing the risk of poor risk distribution.  相似文献

PPP模式是政府公共部门与私营部门合作共同为社会提供公共产品或服务的一种项目运作模式,其优势在于拓宽融资渠道,但是私营部门资金运作是否正规稳定是项目能否成功的关键。所以,政府公共部门应加强对私营部门的财务监管,确保资金按计划到位使用。本文针对PPP模式的基础设施建设项目,论述了财务监管的意义和具体的手段。  相似文献

Problem, research strategy, and findings: Delivering improved public services at lower cost, also known formally as value for money (VfM), is often the main rationale for procuring large infrastructure projects through public–private partnerships (PPPs). However, it is unclear whether the ex ante assessments of PPPs account for key planning concerns, including limitations on community consultation, contractual lock-ins that curtail public flexibility to make future plans, and a political preference for PPPs that may influence the way that projects are structured and evaluated. This set of questions is examined for 28 infrastructure PPPs delivered in Ontario, Canada, and interviews with18 senior political, government, and private-sector participants in the province's PPP industry. We find that transferring of construction risks from government to the private-sector partners drives VfM results, and may overvalue the extent to which planning related risks can be transferred.

Takeaway for practice: PPP contract structures should permit more transparency during the project planning process and preserve the flexibility of governments to control key planning tasks such as user fees, service coordination and facility expansion. Strategies might include: the unbundling of construction and operation phases of the PPP in all but the most unique situations, the use of competitive dialogue tendering to deepen public–private collaboration earlier in the planning process, and the inclusion of contract rebalancing terms to better share rather than transfer project risks.

Research support: This research was funded through a Standard Research Grant from the Social Sciences and Humanities Research Council of Canada (Application Number: 110998).  相似文献

The success of public–private partnership (PPP)–build–operate–transfer (BOT) projects largely depends on effectively mitigating the impact of a variety of risks and uncertainties, especially those influencing the revenue over time. Revenue instability is one of the main obstacles of PPP form of procurement. Government support, which is established as a clause in the concession agreement, should be carefully designed and well formulated. Options which arise from certain clauses in the contract are more valuable for risky projects. The purpose of this paper’s proposed model is to evaluate early fund generation options and also to calculate equitable bounds for a guaranteed revenue for the project sponsor under uncertainty and risk. The model is specially designed to alleviate the concern of revenue risk. To illustrate its applicability the methodology is then applied to a freeway PPP project and a power plant PPP project in Iran. The results show that the value of these options can indeed be significant and by applying the proposed systematic negotiation mechanism both public and private sectors can take advantage of its flexibility at the negotiation table. The proposed mechanisms can facilitate negotiations on the verge of a break down as well as accelerating ongoing negotiations that have become moribund.  相似文献

As part of a comprehensive research into PPP implementation, a two-round Delphi survey was conducted with experienced practitioners to identify the preference of risk allocation in China’s PPP projects. The results show that the public sector would take sole responsibility for the risk “Expropriation and nationalization”, and take the majority of responsibility for 12 other risks related to government or government officials and their actions. Fourteen risks which neither the public nor private sector may be able to deal with them alone are preferred to be shared equally. The private sector would take the majority of responsibility for 10 risks that are at the project level. Interestingly, no risk fell into the category that should be solely allocated to the private sector. Further analysis of the reasons behind these allocation preferences was then conducted. Recommendations on commercial principles and contract terms between the public authorities and private consortia are also made.  相似文献

为了抑制交通 PPP 再谈判的频繁发生,在 PPP 初始合同中引入柔性合同条款,并以交通量波动作为判断社会资本方是否发起再谈判的量化指标,对社会资本方再谈判行为演化规律展开研究。通过构建演化博弈模型分析资本方再谈判行为的演化规律,得到社会资本方再谈判行为的演化与交通量波动的关系;设计基于交通需求风险共担的柔性合同,对比分析有无柔性合同条款下交通 PPP 项目社会资本方再谈判行为的演化规律。研究表明柔性合同可以促使社会资本方在实际交通量低于预期时的策略选择朝着不发起再谈判演化,从而有效抑制交通 PPP 再谈判的发生。研究结论可以为 PPP 柔性合同的设计及社会资本方再谈判行为的治理提供技术支持。  相似文献

Public Private Partnerships (PPPs) cover a range of possible relationships between public and private parties. PPP contracts are typically used in contexts of great uncertainty, such as large construction and infrastructure projects that are realized over a longer period of time. Hence, a major challenge in PPPs is to keep construction progress cost-efficient and on schedule, under continuously changing circumstances. One way to achieve this is through clever contracting, by proactively anticipating potential change in the planning phase and providing flexible contract mechanisms that enable an effective response. The purpose of this article is to discuss potential changes and the subsequent requirement of flexibility in PPP contracts. By flexibility, we mean the ability of the contract to deal with changing circumstances. We set out to do so by studying the available literature on the subject and by analysing the case study of the Blankenburgverbinding in the Netherlands, a Design, Build, Finance and Maintain (DBFM) project that is currently in its planning phase based on 32 interviews. Our main findings are that the timely and accurate recognition of potential changes, combined with the availability of flexible coping mechanisms, provide the stakeholders with a better understanding of the challenges they face in realizing their aims in the pre-contract phase of projects. This understanding helps to better prepare a PPP contract for potential changes.  相似文献
