东西部公路使用效益的结构方程模型

为了解东西部地区公路线路基础设施使用效益的差异,从宏观层面建立了东西部地区客货运量与不同等级公路之间的结构方程模型,实证分析了东西部地区不同等级公路的使用效益。分析表明：东部地区除等外级公路以外,其他各等级公路的使用效益均高于西部地区;东部地区公路线路基础设施对货运量和货运周转量的效应均较大,西部地区公路线路基础设施对客运周转量的效应较大;由于经济发展阶段和产业结构特点不同,收费政策对东西部地区高速公路的使用效益产生了不同的影响。

Structural equation model of road service efficiency between eastern areas and western areas

In order to find the difference of road service efficiency between eastern areas and western areas,this paper sets up a structural equation model between transportation capacity and different highway from macro point of view and analyzes the service efficiency of the two areas. The results show that the service efficiency of different classes of highways, except the substandard road in the eastern areas is higher than that of western areas. The highway infrastructure efficiency of eastern areas is high for freight transportation turnover and capacity, while that in the western areas is high for passenger transportation turnover and capacity. As there are the different economic stages and economic structure, the policy of toll roads may bring different impact on the service efficiency of expressways in the two areas.
