摘要
高速磁浮项目存在建设资金投入大的突出问题,通过对高速磁浮项目费用和效益的影响因素进行定性分析,并在研究日本中央新干线、我国规划高速磁浮项目资金投入的基础上,从降低或延缓资金投入、提升效益等角度出发,提出交通强国背景下高速磁浮经济性发展的若干思考:适配客流需求,科学选定技术标准,包括设计速度、到发线长度、正线数量等;合理选择地下、地面、高架等敷设方式,着力降低地下线比例,以降低建筑工程费;分阶段确定运营主体,降低运营成本,如初期可由地方轨道交通机构负责运营,后期可成立国家级机构负责运营管理;优化服务供给以提升客票收入;联动规划、设计、建设、运营及管理,形成产业链以提升综合效益;统筹社会经济及运输需求等,确定建设时机,优先城市群范围内的试验线,再考虑长大干线建设.
Abstract
To address the challenge of substantial capital investment in high-speed maglev projects,a qualitative analysis was conducted on the factors influencing costs and benefits.Based on the study of capital investment in Japan's Chuo Shinkansen and China's planned high-speed maglev projects,the following considerations are presented to enhance the cost-effective development of high-speed maglev projects in the context of building China's strength in transportation from the perspective of reducing or delaying capital investment and improving benefits:(1)adapting to the passenger flow demand and scientifically selecting technical standards,including the design speed,length of receiving-departure tracks,and the number of main lines;(2)reasonably selecting underground,surface,and elevated systems,minimizing the proportion of underground lines to reduce construction costs;(3)determining the operator stage by stage to reduce the operating costs.For example,the local rail transit organization can be responsible for the operation at the initial stage and a national organization can be established to take charge of operation management at the later stage;(4)optimizing service supply to increase ticket revenue;(5)Linking the planning,design,construction,operation,and management to form an industrial chain to improve comprehensive benefits;(6)coordinating the demand of the society,economy and transportation,determining the construction time,giving priority to test lines within urban agglomerations before expanding to long trunk lines.
