笔者在本文中通过量化及案例分析发现,我国干线运输线路大都表现出3/7规律,即大致上看30%的骨干线网承担了全网70%的货物运输量或车公里数,呈现少数关键的设施承担了高比重或核心运输功能的“运输集中”现象。笔者还总结了美欧等国家或地区通道战略规划的经验,基于帕累托改进的思想,提出了我国关键运输廊道识别思路。本文对优化通道资源配置、完善我国综合运输大通道规划建设具有决策参考的理论价值和现实意义。
Through quantitative analysis and case study, the author finds that most of the trunk lines in China show 3/7 regularity, that is, roughly 30% of the backbone network undertakes 70% of the total network traffic or vehicle kilometers, showing a small number The key facilities assume the “heavy transport” phenomenon of high specific gravity or core transport functions. The author also summarizes the experience of channel strategic planning in the United States and Europe and other countries or regions. Based on Pareto ’s idea of improvement, the author puts forward the idea of identifying the key transport corridors in China. This paper is of theoretical value and practical significance to optimize the allocation of channel resources and improve the planning and construction of China’s major transport corridor.
