Abstract: The rapid development of economy and Motorization has brought serious traffic congestions to several large and middle cities in China. Based on the practice of passenger dedicated railway lines in China, this paper demonstrates the feasibility of passenger dedicated railway to be an intercity transportation mode. Taking Xiamen-Shenzhen railway line as an example, this paper analyzes the economic and social benefits of Huizhou-Shenzhen intercity transportation, which contains the demand of passenger flow, the adaptability of dedicated railway to intercity transportation, engineering requirements, and transportation operating effect. It indicates that Huizhou-Shenzhen railway line being an intercity transportation mode can improve the financial situation of Xiamen-Shenzhen railway line and make the financial internal rate of return achieve 6.5% increase. Moreover, the passenger service level will also be improved significantly. Thus, the development space of Shenzhen city will be expanded and the speed for Huizhou to be a member of the Chu Chiang Delta Economic Circle be increased.

摘要： 城市经济及机动化的发展导致我国大中城市道路交通出现了较严重的拥挤现象。本文针对目前我国铁路客运专线建设的实践，分析了利用客运专线于城际交通的可能性。论文以厦深铁路为例，从客流需求、客运专线设施对城际交通特点的适应性、相关工程技术改造要求以及交通运行效果四方面系统分析了惠深铁路开展城际客运服务的经济与社会效益。研究表明：惠深铁路兼顾城际客运功能，不仅可大幅提高厦深铁路的财务收支状况，使综合财务内部收益率达到6.5%；同时还可大幅度提高深惠间城际客运的服务水平，扩展深圳市的发展空间，加速惠州融入珠三角经济圈的进程。
