摘要： 我国铁路、公路、航运等运输方式在客货运输通道中普遍存在双向负荷不平衡现象。为提升运输线路低负荷方向能力利用率并合理评估双向运输效益，从运输通道角度建立了运输线路能力利用率与效益评估模型，并设置算例研究运价优惠策略对低负荷方向线路能力利用率以及企业运输效益的影响。研究表明：在通道上存在公路和铁路两种方式的情景中，考虑中短运距(600~650 km)条件下，当铁路运价优惠程度由0增加至60%，线路能力利用率增长28.63%，且增幅逐渐提升。铁路运价优惠程度由0增至15%，铁路双向运输效益上涨0.92%，随后略有下降；运价优惠程度超过30%，双向运输效益下降速度逐渐增加。运输企业通过合理制定运价优惠策略，有望实现在保障运输效益的同时，提高低负荷方向线路能力利用率。随着运输距离增加至约1500 km时，可将最大运价优惠程度提升至35%。

Abstract: The phenomenon of bi-directional load imbalance commonly exists in passenger and cargo transportation channels of railway, highway and shipping in China. To improve the capacity utilization rate of transport lines in the low-load direction and to reasonably evaluate the two-way transport benefits, a model was established to evaluate the capacity utilization rate and benefits of transport lines, and an example was set to study the influence of concessionary tariff strategy on the capacity utilization rate in the low-load direction and the transport benefits of enterprises. The study shows that in the scenario of the existence of road and railway in the channel, considering the medium distance (600~650 km), the capacity utilization rate of a line increases by 28.63% when the concessionary tariff increases from 0 to 60%, and the increase increases gradually. The rate of increase in the degree of fare concessions from 0 to 15% increases the two-way transport efficiency by 0.92%, followed by a slight decrease; the rate of decrease in the two-way transport efficiency increases gradually when the degree of fare concessions exceeds 30%. Transport companies can control the degree of fare preference within the range reasonably, which is expected to achieve the protection of transport efficiency while improving the utilization of line capacity in the low-load direction. As the transport distance increases to around 1500 km, the maximum degree of fare concession can be increased to 35%.
