资源分配与优化贯穿PPP项目生命周期,影响到PPP项目风险分配和风险控制效率,进而决定PPP项目的成败。项目实际实施过程中,政府和社会资本都存在转移风险的现象,合理的聚集、分配、优化资源和风险已经成为PPP模式理论及实践的关键问题。在确定PPP项目资源分配主体的基础上,构建资源和风险分配的博弈模型,探讨资源配置优化和风险分配优化的逻辑关系以及其对PPP项目成功的重要作用机理,并以郑州市白庙水厂PPP项目为例进行验证,期望为PPP项目资源和风险分配优化提供参考。 相似文献

PPP项目的直接分担主体是公共部门和私人部门。在分析模糊控制系统与人脑决策系统的关联性基础上,建立以模糊控制系统为主体的PPP风险分担决策模型。通过该模型,对风险分担原则进行了具体化,并对决策者的经验和主观判断进行了量化和推理,从而得到风险分担的决策。运用MATLAB工具实现了该模型,并针对某地铁PPP项目进行了问卷调查和风险分担决策研究,为现实中的实际操作提供了一种有效思路。 相似文献

基础设施PPP项目的风险分担 总被引:11,自引:1,他引:11
基础设施PPP(Public-Private Partnership)项目投资大、时间长、风险高、合同结构相对复杂,项目谈判过程往往旷日持久,很多时候由于在实施过程中无法兑现承诺或发生其他原因而出现争议,以至于实践中只有少量PPP项目能正常运作.其中,很大原因在于公共部门和私营部门之间缺乏公平的定量风险分担标准.本文通过详尽的文献综述,首先归纳风险分担在项目过程中的时点和要点,并总结风险分担对项目资金价值的影响,最后比较分析已有的风险分担准则和不同的风险分担结果,以期为PPP项目风险分担的研究和实际操作提供可参考依据. 相似文献

为有效提高 PPP 项目中政企合作水平和效率,以政企控制权初始分配作为研究节点,基于政企风险偏好和有限理性状态,构建风险投资期望效用模型,得出不同风险偏好组合下的初始控制权分配情景。并从政企风险偏好组合下的 4 种情景,运用算例模拟论证不同风险偏好对控制权初始分配及政府风险投资期望效用的影响。结果表明,政府风险中性时社会资本初始控制权份额与其风险规避程度呈负相关且有最低限度,反之与其风险趋向程度呈正相关且有最高限度。不同风险偏好组合对政府风险投资期望效用有不同影响。因此,政府应充分考虑双方风险偏好,确定最优初始控制权分配份额,以促进PPP 项目高效实施。 相似文献

PPPs have become a popular way to supply infrastructure around the world. However, compared with developed countries, most developing countries have failed to attract private investment over the past years. Risk allocation and governance environment (e.g., the extent of public participation, the level of political stability, the quality of public services, the ability of regulations, abiding the law, and the extent of corruption) may be important factors. To test the hypotheses, using about 4560 PPP projects in 138 developing countries from 2002 to 2015, this paper applies the Tobit regression model to investigate the interaction effect of governance environment and risk assumed by private partners on private investment. Results indicate that private partners assume that less risk can attract more private investment, and that a higher level of governance (control of corruption, government effectiveness, regulatory quality, and rule of law) reduces the negative influence of risk assumed by private partners on private investments. 相似文献

This paper aims to establish, train, validate, and test artificial neural network (ANN) models for modelling risk allocation decision-making process in public-private partnership (PPP) projects, mainly drawing upon transaction cost economics. An industry-wide questionnaire survey was conducted to examine the risk allocation practice in PPP projects and collect the data for training the ANN models. The training and evaluation results, when compared with those of using traditional MLR modelling technique, show that the ANN models are satisfactory for modelling risk allocation decision-making process. The empirical evidence further verifies that it is appropriate to utilize transaction cost economics to interpret risk allocation decision-making process. It is recommended that, in addition to partners' risk management mechanism maturity level, decision-makers, both from public and private sectors, should also seriously consider influential factors including partner's risk management routines, partners' cooperation history, partners' risk management commitment, and risk management environmental uncertainty. All these factors influence the formation of optimal risk allocation strategies, either by their individual or interacting effects. 相似文献

The unbalanced allocation of risks among the contracting parties is an important decision leading to increase of the total cost of a specific project and affects the overall relationship between the contracting parties. Due to common risk allocation decision-making process is based on experiential knowledge, is subjective and implicit. This paper presents a fuzzy adaptive decision making model for selection of balanced risk allocation which transforms the linguistic principles and experiential expert knowledge into a more usable and systematic quantitative-based analysis by using the fuzzy logic. The objectives of balanced risk allocation are developed based on the concept of Competence-Tendency trade-off. The proposed model integrates fuzzy logic qualitative approach and analytic hierarchy process (AHP) adaptive capabilities to evaluate allocation of project risks and determine best party to bear each one. Results from this model show its high capability in addressing most proper risk allocation with least contingency applied to the owner. 相似文献
