系统视角下城市一体化交通节点项目投融资机制优化研究——以南京为例

摘要

BOT投融资模式改变了城市重大基础施建设仅靠政府出资的单一形式,调动了社会资本参与城市重大基础设施建设的积极性,加快了城市发展进程。但由BOT融资模式自身决定的项目使用收费机制,使得交通节点BOT项目,成为制约城市经济社会一体化发展的＂软＂瓶颈。本文以南京市为例,基于系统论视角,关注城市一体化进程中交通节点BOT项目的外部效应,打破条块分割,将项目与正外部性受益主体作为一个整体系统,提出城市一体化交通节点项目投融资机制优化的新思路,通过外部效应内部化,改变BOT项目通过收费回本获利的传统机制,实现城市发展总体效益的最大化。%BOT financing has changed the original infrastructure investment and financing systems,social capital positively takes part in it,and urbanization process is faster than before.However,charges in BOT communication infrastructure restrict city integration development.Based on System Theory,the paper focuses on the external effects in BOT infrastructure,and brings a new way in city infrastructure investment and financing systems.As a result,the new way can reduce using cost in BOT infrastructure,and optimize the city development efficiency.
