基于县级单元城际物流联系分析研究——以辽宁省为例

综合运用运输联系等相关理论,围绕城际物流联系生成、分布等问题,同时关注省内各区域之间物流联系以及与省外区域的联系,利用高速公路货车通行OD数据,通过分布熵、洛伦兹曲线、物流联系强度、物流联系紧密度、物流联系分区等指标、方法分析研究城际物流联系的方向、强弱程度及其特征,可以为城际物流网络系统建立以及交通基础设施建设发展提供理论支持和参考。以辽宁省高速公路为例进行的实证分析,对于加强辽宁省交通基础设施优化配置,实施三大区域发展战略,促进区域经济协调发展等具有重要意义。

A Study on Intercity Logistics Contact Based on County Units With Special Reference to Liaoning Province

This paper argues that to provide a theoretical support and reference for the establishment of intercity logistics network system and the transportation infrastructure development, it is of benefit to analyze the direction, intensity and related characteristics of intercity logistics contact. It is also proposed to study the distribution and contact formation of intercity logistics with transport link and other related theories, to take into consideration the logistics links within and between provinces by making use of highway truck OD data, and to analyze various indexes such as the distribution of entropy, Lorenz curve, logistics contact strength, contact tightness, logistics contact partition and so on. The empirical studies of the expressway of Liaoning Province are of vital significance to enhance Liaoning transportation infrastructure optimization, to implement the strategy of three-region development, and to promote regional economic coordinated development.
