摘　　要：针对联程联运的衍生产品“行李直挂”服务的最优定价问题,在对比分析携带行李的旅客采用直挂与非直挂模式下出行链差异性的基础上,考虑出行路径的客观条件和包括旅客不舒适性感受、换乘心理负担在内的心理因素,从在乘与换乘两个阶段量化直挂与非直挂模式下旅客的出行广义费用,并综合考虑运输商的利润与行李直挂所带来的价值链增值,提出服务价格的双层规划优化模型。上层以价值链最大为目标,下层为城市群多方式交通系统的平衡分配模型,最后通过算例对模型构建的合理性进行验证。结果表明:在铁路与航空的旅客运价分别为0.45元/(人·km)与0.75元/(人·km),两种方式下的行李直挂运价分别取0.0038元/(kg·km)与0.0062元/(kg·km)时可以达到价值链的最大化。研究结果为推进城市群旅客联程运输服务提供了理论依据和参考。This study determines the optimal pricing for“Baggage Interline”service,which is a derivative product of urban agglomeration intermodal transport service.The differences of travel chain between the modes of Baggage and Non-Baggage Interline are compared and analyzed.Stages of in-ride and transfer considering the objective conditions of travel paths and the psychological factors,which includes passengers’uncomfortable feelings and transfer psychological burden,are used to construct the generalized travel cost of passengers between the modes.Comprehensively considering the profit of the transporters and the value-added of the value chain brought by the“Baggage Interline”service,a bi-level programming model with the optimal service price is proposed.The upper level maximizes the value chain,and the lower level is the balanced allocation model of the multi-mode transportation system of the urban agglomeration.Finally,the rationality of the model is verified using an example.The results indicate that when the railway and airline rates are 0.45 and 0.75 yuan/(passenger·km),the value chain can be maximized when the service charge of“Baggage Interline”service is 0.0038 and 0.0062 yuan/(kg·km)separately.This provides a theoretical basis for promoting the development of passenger intermodal transport in urban agglomeration.
