基于广义费用的城际运输方式竞争力模型

    A Competitiveness Model of Intercity Transportation Modes Based on Generalized Cost

    • 摘要: 为分析城际间各类运输方式竞争力,针对客运、货运2个方面分别构建竞争力模型。针对公路运输中私家车出行和长途客运出行广义费用构成的差异性,引入巢式Logit构建旅客运输方式竞争力模型。考虑货物自身性质和特点以及托运方对价格的敏感程度划分城际间货物种类,针对不同种类货物,分别提出修正系数对广义费用函数进行修正,构建基于Influ-Logit的货物运输方式竞争力模型。以哈尔滨市—佳木斯市城际间客货运输方式为例开展实证研究。结果表明:所构建的模型可以较好地描述城际各交通运输方式的客货竞争力以及相关影响因素变化下竞争力的变化情况,为相关运输企业制定优化对策、调整运输策略、提升自身竞争力提供理论参考。

       

      Abstract: To analyze the competitiveness of intercity transportation modes, a competitiveness analysis model of passenger and freight transportation was constructed, respectively. Considering the differences of the components of generalized cost between private car and public transportation of road intercity transport, the Nested-Logit model was introduced to construct the competitiveness analysis model of different passenger transportation modes. The intercity freight transportation was classified on the basis of characteristic of freight and consignor's sensitivity towards freight rate. Correction factors were proposed to modify the generalized cost function for each freight type. Then, the competitiveness analysis model of different freight transportation modes was constructed based on Influ-Logit model. Taking the intercity passenger and freight transportation modes from Harbin to Jiamusi as an example to carry out an empirical study of the model constructed. Results show that the constructed model can better describe the competitiveness of various intercity passenger and freight transportation modes and the competitiveness under the changes of related influencing factors, which provide theoretical reference for relevant transportation enterprise to formulate optimization strategies, adjust transportation strategies, and enhance their competitiveness.
