摘要:研究目的:近年来，我国城市化率迅速提高，城市人口已经达到全国总人口的一半以上。随着我国城市 化进程的加速，原有的城市交通基础设施已满足不了城市化发展的要求，轨道交通不仅是解决城市交通问题 的重要手段，也是我国城市化发展的必然选择。而投融资是城市轨道交通建设中的一个关键问题。研究结论：1)我国的城市轨道交通建设已经从单一的政府投资模式向多种类型的项目融资模式转化， 城市轨道交通建设要实现投资方式市场化和主体多元化，项目融资是一条重要的途径；2)城市轨道交通建 设项目只有尽可能地节约投资成本，才能取得更好的经济效益，城市轨道交通建设实现项目法人负责制、资本 金制等，有利于促进建设管理的质量和投资效益的提高；3)本研究有利于促进城市轨道交通的建设与发展， 可为解决城市轨道交通建设中急需的资金问题提供借鉴。

Abstract：Research purposes： In recent years，Chinas urbanization rate increased quickly，the urban population has reached more than half of the total population. With the acceleration of Chinas urbanization process，the original urban transportation infrastructure cant already satisfy the requirements of the development of urbanization，rail transportation is not only the important means to solve the problem of urban traffic， but also is the inevitable choice of urbanization development in our country. The investment and financing is a key problem for urban rail transit construction. Research conclusions ： ( 1 ) The urban rail transit construction in China has been improved from a single mode of government investment to various types of project financing modes， in order to realize marketization of investment way and the diversification of subjects in the urban rail transit construction, project financing is an important way. (2) Only by saving investment cost as much as possible， urban rail transit construction project can achieve better economic benefit. For urban rail transit construction，implementing the project legal person responsibility system，capital system and so on， is conducive to improve the quality of the construction management and investment benefit. (3) This research is helpful to promote the construction and development of urban rail transit， and solve the problem of much - needed funds in the construction of urban rail transit.
