【摘要】：政府与社会资本合作(PPP)模式作为一种新型的公共品提供方式,近年来在全国范围内迅速推广。然而在实践过程中出现的失败案例以及不同行业中PPP模式应用的分布差异均表明,行业特点能够显著影响PPP项目的执行效果。本文抽象出不同行业所具备的行业特征,依此设计政府和企业间提供公共服务的最优合约,讨论行业特征影响合约执行效果的因果机制。研究发现:并非所有行业都适合应用PPP模式。对具有"建设期对运营期的外部性较高""运营期投入成本较低""建设期风险较高""运营期风险较低"等特征的行业来说,应用PPP模式更为合适;反之则应用传统的政府购买服务模式更为合适。此外,两种模式在部分行业中的经济效率仍然不明确,其依赖于其他的技术条件和外部环境。
[Abstract]:As a new type of public goods supply mode, the government-social capital cooperation model has been popularized rapidly in the country in recent years.However, the failure cases in practice and the differences in the distribution of PPP application in different industries show that the characteristics of the industry can significantly affect the implementation effect of PPP projects.This paper abstracts the industry characteristics of different industries, designs the optimal contract between government and enterprise to provide public service, and discusses the causality mechanism that industry characteristics affect the effect of contract execution.Research found: not all industries are suitable for the application of PPP mode.For the industries with the characteristics of "high externality in the construction period", "low input cost in the operation period", "high risk in the construction period" and "low risk in the operation period", it is more appropriate to apply the PPP model.On the contrary, it is more appropriate to apply the traditional government purchase service mode.In addition, the economic efficiency of the two models in some industries is still unclear, which depends on other technical conditions and external environment.
