运输供给的品质特性

Quality Characteristics of Transportation Supply

在分析运输供需理论缺陷的基础上,将运输供给的品质特性重新界定为能被消费者感受到的、以运输过程为主体的、系统描述运输供给品质的指标体系。提出运输供给的品质特性由可达性、时效性、技术经济保障、经济性以及舒适性5个方面构成,并重新建立评价指标体系加以量化描述。鉴于运输供给具有鲜明的异质性,提出了区分不同类型运输需求(价格敏感型、品质敏感型和基本运输需求)、揭示运输供需关系和采用分类预测法预测运输需求的基本思路。

After analyzing the defects in present studies on the quality characteristics of transportation supply, this paper redefines the quality characteristics of transportation supply as an index systems systematically that can describe the quality of transportation supply, involve in the transportation process and be benificial to consumers. The quality characteristics of transportation supply includes accessibility, timing, technical and economic guarantee, economy and comfortableness, and all of which are quantitatively discussed in details by establishing new evaluation index system. Further more, considering the distinct differences in the quality characteristics of different transportation supplies, the authors try to analyze the relationship between transportation supply and demand by dividing the demand into three types： pricesensitive demand, quality-sensitive demand and basic demand, and also forecast the transportation demand by taxonomy.
