公路货运效率及影响因素研究 ——皖江城市带比较研究

采用外生性影响因素与随机前沿生产函数模型联合估计的方法，对公路货运效率展开实证研究.结果显示：皖江城市带建设对公路货运效率具有积极的推动作用，但存在“塌陷”现象；考察期间安徽省公路货运技术效率仍处于较低水平，存在公路货运业发展粗放，资源浪费现象；经济发展水平、财政及开放程度促进技术效率提升，但该作用存在地区差异；产业结构、等级公路占比阻碍技术效率提升，运输需求的增加及等级公路的投资建设并不意味着运输效率的提升.最后，根据上述发现并结合实际给出优化安徽省公路货运效率的建议.

Efficiency of Highway Cargo Transportation and Its Effect Factors Based on Perspective of Wanjiang Demonstration Zone

Using estimation method of exogenous factors and stochastic frontier production function model, an empirical study on highway freight efficiency in Anhui province is carried out. Results show that highway freight transport technology is still in the low efficiency during the investigation in Anhui province, the extensively highway freight industry development and wasting of resources. The level of economic development, finance and the degree of opening promote technical efficiency, but there are regional differences in this effect. Industrial structure and level highway of blocking technology efficiency, the increase of transport demand and the level of highway investment don’t mean the promoting of the efficiency of transportation. Finally, based on the above findings and combined with practical, suggestions on optimizing highway freight efficiency in Anhui province are proposed.
