从城市财政可持续发展视角,构建了成本和收益平衡条件下的城市轨道交通定价模型,分析了城市对外扩展距离和城市轨道交通定价的关系,提出了计算方法,进行了算例分析。研究表明:城市轨道交通对外扩展距离受到客流量和票价率相互作用影响,一方面,随着对外扩展距离增长,在票价不变前提下,由于客流量急剧降低,政府补贴对促进降低票价率的作用日益减弱;另一方面,相同的政府补贴额,过高的票价率,会导致客流量减少,进而使城市轨道交通对外扩展的距离减少。
From the perspective of sustainable development of urban finance, the pricing model of urban rail transit under the condition of balance of costs and benefits is established. The relationship between the urban outward expansion distance and the pricing of urban rail transit is analyzed. The calculation method and the example analysis are given. The research shows that the external expansion distance of urban rail transit is affected by the interaction between passenger flow and ticket price. On the one hand, with the increase of external expansion distance, with the fare unchanged, due to the sharp drop in passenger flow, On the other hand, the same amount of government subsidies and excessive fare rates will lead to a decrease in passenger flow, which in turn will reduce the distance the urban rail transit will expand overseas.
