高速铁路是运输市场竞争和科学技术进步的重大成就,高速铁路对区域发展具有显著影响。高速铁路项目可行与否不仅取决于短期经济效益,还依赖于项目所能带来的社会效益是否能够补偿基础设施建设成本、运营与维护成本,需要考虑项目所带来的时间节约效益、战略价值、环境影响、区域发展作用等。在既定成本条件下,高速铁路投资的预期社会净收益主要取决于乘客的数量、组成结构(转移乘客、诱发乘客)、沿线的交通拥堵程度。高速铁路项目需要能够补偿其高额运营与维护费用的足够大量人群带来足够的经济价值,不仅需要大量的旅客目标市场,还要有较高的支付能力和支付意愿。高速铁路是高技术难度与复杂程度融于一体的现代系统工程,是运载量巨大的公共交通工具,其技术安全水平的稳定性不可避免地影响旅客的选择,影响客运量水平的变化。
High-speed railway is a major achievement in competition in the transport market and scientific and technological progress. High-speed railway has a significant impact on regional development. The feasibility of high-speed railway project not only depends on the short-term economic benefits, but also depends on whether the social benefits of the project can compensate for the cost of infrastructure construction, operation and maintenance costs, and needs to consider the project’s time saving benefits and strategic value , Environmental impact, the role of regional development. The expected net social benefits of HSR investment at established costs depend mainly on the number of passengers, the composition of the structure (passengers being transferred, evoking passengers) and the degree of traffic congestion along the route. High-speed rail projects require sufficient economic value for a large enough population to compensate for their high operating and maintenance costs, not only for large passenger target markets, but also for higher affordability and willingness to pay. High-speed railway is a modern system engineering integrating high-tech difficulty and complexity. It is a large-scale public transport. The stability of its technical safety level will inevitably affect the choice of passengers and affect the changes of passenger traffic levels.
