【摘要】 政府和社会资本合作(Public Private Partnership,简称为PPP)是政府和社会资本建立合作以实现风险分担和收益共享的契约安排,既能缓解基础设施领域的公共资金约束,又能提高基础设施公共服务的有效供给。随着“一带一路”倡议的提出,PPP模式作为提高沿线国家公共服务效率、推动沿线国家基础设施互联互通的重要举措,在能源、交通运输、水利建设、市政工程等领域得以运用。尽管PPP模式在“一带一路”沿线国家基础设施领域得到了大量运用,但PPP项目投资少等问题屡见不鲜,究其原因,是“一带一路”沿线国家的政府质量、经济环境和已有基础设施存在问题。因此本文在“一带一路”的战略背景下,利用“一带一路”沿线32个国家2002-2018年的面板数据,构建有调节的中介效应模型,实证分析政府质量、经济环境、已有基础设施与基础设施PPP项目投资之间的关系,并进一步分析经济环境在政府质量与基础设施PPP项目投资间的中介作用,已有基础设施对经济环境与基础设施PPP项目投资关系的调节作用,最后使用Bootstrap对有调节的中介效应模型进行稳健性检验。研究发现:(1)政府质量(政府规模、政府行政效率、政府经济管制、政府法治质量)、经济环境和已有基础设施均正向影响基础设施PPP项目投资。政府质量较高意味着政府规模适度、经济管制合理、行政效率和法治质量较高,有利于增强政企双方的契约精神,降低企业投资的外部成本和合同风险,吸引私人资本对基础设施PPP项目的投资。良好的经济环境意味着经济发展水平较高和市场规模较大,有利于私人资本尽快收回PPP项目的投资成本,提高盈利水平。已有基础设施较完善有利于降低PPP项目的工程成本,增加PPP项目的私人投资。(2)经济环境在政府质量与基础设施PPP项目投资间起着中介作用。(3)已有基础设施正向调节经济环境与基础设施PPP项目投资关系,即已有基础设施越完善,经济环境对基础设施PPP项目投资的正向作用越强,反之亦然。研究结论分析了“一带一路”沿线国家基础设施PPP项目面临的投资困境,揭示了政府质量、经济环境和已有基础设施作用于基础设施PPP项目投资的复杂机制,为“一带一路”倡议战略背景下,增加沿线国家基础设施PPP项目投资,推动基础设施PPP项目顺利开展,提供了一定的理论和实践意义。更多还原

【Abstract】 The public private partnership(PPP)is a contractual arrangement between the government and social capital to establish cooperation to realize risk sharing and income sharing.It can not only alleviate the constraints of public funds in the field of infrastructure,but also improve the effective supply of public services in infrastructure.With the proposal of the "the Belt and Road" initiative,PPP mode,as an important measure to improve the efficiency of public services and promote the interconnection of infrastructure in countries along the line,has been applied in the fields of energy,transportation,water conservancy construction,municipal engineering,etc.Although the PPP model has been widely used in the infrastructure field of countries along the "the Belt and Road",problems such as low investment in PPP projects are common.The reason is that there are problems in the government quality,economic environment and existing infrastructure of countries along the "the Belt and Road".Therefore,under the strategic background of the "the Belt and Road",this paper uses the panel data of 32 countries along the "the Belt and Road" from 2002 to2018 to build an moderated mediation effect model,empirically analyze the relationship between government quality,economic environment,existing infrastructure and Infrastructure PPP project investment,and further analyze the mediation effect of economic environment between government quality and Infrastructure PPP project investment,the moderation effect of existing infrastructure on the investment relationship between economic environment and Infrastructure PPP projects.Finally,Bootstrap is used to test the robustness of the moderated mediation effect model.The research finds that:(1)the government quality(government scale,government administrative efficiency,government economic regulation,government rule of law quality),economic environment and existing infrastructure all positively affect the Infrastructure PPP project investment.Higher government quality means moderate government scale,reasonable economic regulation,high administrative efficiency and high quality of rule of law,which is conducive to enhancing the contractual spirit between government and enterprises,reducing the external cost and contract risk of enterprise investment,and attracting private capital investment in Infrastructure PPP projects.A good economic environment means a high level of economic development and a large market scale,which is conducive to private capital to recover the investment cost of PPP projects as soon as possible and improve the profitability.The existing infrastructure is relatively complete,which is conducive to reducing the engineering cost of PPP projects and increasing private investment in PPP projects.(2)Economic environment plays an mediation role between government quality and Infrastructure PPP project investment.(3)The existing infrastructure positively moderates the relationship between economic environment and Infrastructure PPP project investment,that is,the more perfect the existing infrastructure,the stronger the positive effect of economic environment on Infrastructure PPP project investment,and vice versa.The research conclusion analyzes the investment dilemma faced by Infrastructure PPP projects in countries along the "the Belt and Road",reveals the complex mechanism of government quality,economic environment and existing infrastructure on Infrastructure PPP project investment,and provides certain theoretical and practical significance for increasing Infrastructure PPP project investment in countries along the "the Belt and Road" initiative under the strategic background of the "the Belt and Road" initiative and promoting the smooth implementation of Infrastructure PPP projects.更多还原
