对市域快速轨道交通建设的思考

Thoughts on the Development of Metropolitan Rapid Rail Transit

日本东京因其城市性质、规模以及人口密度与中国大城市相似度高,其市域快速轨道交通发展中站城一体化和铁路民营化效果良好,常作为中国城市研究和学习的重点。然而,中国大城市的市域快速轨道交通在发展时机和既有铁路资源基础方面与东京存在巨大差异,很难复制其成功经验。在分析东京市域快速轨道交通发展特点以及与中国城市现状差别的基础上,建议中国市域快速轨道交通在决策过程中应统筹考虑建设投入和服务效果,追求单位投资效益最大化,而非不切实际地要求线路工程投资总额低同时服务水平高。

Because of similarities in urban functionalities,scale and population density between Tokyo and large cities in China,Tokyo,a city has better results in the development of integrating its rapid rail transit stations with urban area and the rail transit privatization,is often taken as a successful case study by Chinese cities.However,because of the huge difference in development timing of metropolitan rapid rail transit and the existing railway infrastructure between Chinese large cities and Tokyo,it is hard to duplicate Tokyo's success in China.Based on the analysis of development characteristics of Tokyo's rapid rail transit and the development gaps among Chinese cities,the paper suggests that Chinese cities comprehensively consider the construction investment and service effectiveness while establishing polices for developing metropolitan rapid rail transit,It is important to maximize the investment returns instead of unrealistically requesting the low investment while asking for high-quality of service.
