基础设施供给机制与投资模型

基础设施是以社会间接资本的形式反映到经济体中，增加基础设施供给，实质上就是扩大社会公共资本，为使用者节约社会间接成本；基础设施排他成本、信息收集成本、政府的偏好对不同供给方式的经济效率，进而对供给方式的选择有重要影响，实现风险分担、利益共享是基础设施投资决策应遵循的基本原则之一，它是形成适应基础设施建设与经营特点的产权制度、自我激励机制、自我规制机制的基础。

Infrastructure Provision Mechanism and Investment Models

Due to the fact that infrastructure is manifested in the economy as social indirect capital assets,improvement of infrastructure provision is substantially expansion of social public assets and reduction of social indirect cost for users so that the businesses will be better supported for industrial development.Different infrastructures have different economic natures,which determined that combination of infrastructure of various types and characteristics may choose multiple provision mechanisms.By dissembling the production process both vertically and horizontally,technological progress may contribute to change of public products' natures and make the whole chain de-monopolized.Meanwhile,when infrastructure development is concerned,none of the stakeholders is allowed to expand its interest infinitely because the circulation chain of infrastructure development will be broken as soon as such expansion goes beyond the acceptable range of other stakeholders.In a word,one of the principles for infrastructure development is to benefit all the related parties as much as possible.
