New advances in research on public-private partnership(PPP)in transportation infrastructure from the perspective of economics

为促进经济健康稳定可持续发展,提高交通基础设施公共服务质量、增加公共产品有效供给,从经济学视角出发,对国内外学者近年来关于交通基础设施建设中政府和社会资本合作(PPP)的研究成果进行梳理,按照文献的发展脉络和逻辑关系对交通基础设施PPP进行总结和概括,从项目定价、公私合作、风险承担和绩效评估四个维度探讨相关研究的新进展。研究发现,交通基础设施建设PPP的研究越来越多,对实践的影响也日渐增强;从项目定价和公私合作这两个维度对交通基础设施建设相关PPP的研究更具有规范性,而风险承担和绩效评估创新性地从制度经济学和管理学角度对交通基础设施建设PPP项目进行了研究;未来从经济学视角开展PPP研究,需要运用更加宏观的视角,整体研究和阐述PPP中的系列问题,从政府部门、企业、责任单位、管理层、社会效用等多个角度提出改进路径,这对整体提升国内公共基础设施领域PPP取得社会成效乃至经济高质量发展程度都具有积极意义。
