Risks, Challenges and Value for Money of Public–Private Partnerships
研究了澳大利亚M4高速公路PPP项目在特许期结束时的独特问题、挑战和风险，揭示了合同模糊性、关系风险及重新整合风险，为PPP长期神话提供了实证反驳。
Abstract This study examines the unique issues, challenges and risks emerging at the end of a public‐private partnership (PPP) concession. The M4 motorway is the first Australian PPP that has reached the end of its concession. The absence of formal guidance on contractual closure created challenges for the partners in interpreting contract ambiguities, and in reaching agreement on the processes needed to close the contract. These challenges had posed several relational risks, the mitigations of which were supported by the relational contract partners developed over the concession term, and their reciprocity and ethical motivations. The reintegration risk emerged in the handback exemplifies the limits of controls designed for legitimacy concerns to resolve coordination problems. The political settlement for value for money was gestured by lifting the toll after the concession ended. In providing unparalleled empirical evidence against the long‐term ‘myths’ of PPPs, the study counters the criticism over PPPs’ impossibilities to handle uncertainties and to transfer risk.
