摘要: 我国交通运输已由各方式间独立发展向一体化融合发展转变,快捷货物运输是综合交通运输融合发展的新兴关键领域,其各运输方式间临界运距的研究对合理运输结构的确定具有重要意义。针对既有研究对于临界运距问题主观赋权的不足,本文首先基于快捷货运分担率模型建立临界运距与服务属性及权重系数表达式,然后基于CRITIC(Criteria Importance Though Intercriteria Correlation) 法对权重系数进行客观测算,最后通过实例进行模型分析验证及结果对比。实例结果表明:客观赋权法可以使各服务属性权重系数随运距增加而产生异质性;经济性在300~400 km和900~1100 km内波动幅度最大;便捷性与经济性的运距临界点为327km,其重要程度随运距增加会高于经济性;客观赋权对快捷货运各方式间临界运距的影响主要体现在高铁快运绝对优势运距区间的扩大,由主观赋权下700~1500km转变为400~2000km。

Abstract: The transportation in China has shifted from independent development among various modes to integrated development. Express goods transportation is an emerging key field for the integrated development of integrated transportation. The study of the critical distance for express goods transportation modes is of great significance to determine the reasonable transportation structure. In response to the shortcomings of subjective weighting in existing research on critical distance issues, expression for critical distance and weight coefficients of service attribute is established based on the express goods sharing rate model. Then, the weight coefficients are objectively calculated based on the CRITIC (Criteria Importance Though Intercriteria Correlation) method. The model is analyzed and validated through example analysis, and the results are compared between different scenarios. The results indicate that: the objective assignment method can make the weight coefficients of each service attribute heterogeneous with the increase of transportation distance; economy has the largest fluctuation in 300 to 400 km and 900 to 1100 km; the transportation distance threshold between convenience and economy is 327 km, and its importance will be higher than economy with the increase of transportation distance. The influence of objective weighting on the critical distance between the modes of express goods transportation is mainly reflected in the expansion of the absolute dominant distance range of high-speed rail express transportation, which changes from 700~1500 km to 400~2000 km.
