[摘 要] 基于厂商中间层理论的崭新视角,对PPP这种公私合作制模式存在的经济学动因进行经济学分析,并阐述其在提高公共部门社会效益和私营部门经济效益方面的优势,论证其在公共基础设施项目管理中的合作效率,揭示公私合作制模式的经济学本质。结果表明PPP混合组织通过为公私部门提供公共品质量等信息可以降低公共品供给交易的不确定性,增进公共品供给的期望社会收益,对公共品质量保证和监督能够有效克服公共品供给市场上的逆向选择和道德风险问题。

随着我国工业化和城市化进程的快速推进,基础设施项目的建设需求也日趋增长,当政府财政资金不足以满足公共基础设施项目建设和运营的需求时,公共部门可以采取适宜的合同安排来引导私人部门参与到公共基础设施项目建设中来,形成公共基础设施项目建设领域的公私合作制(public-privatepartnership,简称PPP),这种合同关系在经济学中解释为委托代理关系,借以吸纳社会资本,引入市场竞争机制,有效缓解政府财政压力,降低工程造价,提高项目运营管理效率。……
