摘　　要：票价是旅客选择出行方式的决定因素之一,合理定制高速铁路票价具有重大意义。本文在高速铁路定价的双层规划模型中考虑社会因素,把社会福利因素添加至上层规划模型中,将社会福利最大化作为上层规划的目标,将旅客广义出行费用最低作为下层规划的目标,并采用灵敏度分析法求解,得到使社会福利最大化的票价。然后采用模型对成渝通道内成渝中线高速铁路二等座的社会定价水平进行分析,为成渝中线高速铁路开通运营后的票价定制提供参考。The fare is a determinant for the passengers to choose the travel mode,and it is of great significance to reasonably make decisions on the fare of high-speed railway passenger services.In this paper,social considerations are taken into the bi-level programming model of high-speed railway pricing,where social welfare is added to the upper-level programming model by regarding maximizing social welfare as the goal of the upper-level programming,and minimizing the generalized travel cost of passengers as the goal of the lower-level programming.Then sensitivity analysis is used to determine the fare that maximizes social welfare.Then,the model is used to analyze the social pricing level of the second-class seat of the Second Chengdu-Chongqing High-speed Railway in Chengdu-Chongqing Passage,which provides a reference for making decisions on fare after the opening and operation of this railway.
