对区域物流网络的研究进行了基本的总结和归纳,分析了轴辐侍服网络的内涵及其在区域物流网络构建中的比较优势.针对长三角目前区域物流发展的基本情况,指出了当前该区域存在着网络布局不合理、层次不清晰等问题,设计了物流中心性指数的指标评价体系,确立了网络的一级轴心(hub)和二级轴心(sub-hub);考虑到城市间物流强度数据获取具有一定的难度,作者通过交通成本作为网络构筑的条件,以势能模型(potential)为运算原理,通过区域内物流成本的位势差,即各个节点与轴心间交通成本,实现对网络的构建和优化;以GIS的网络分析方法(栅格算法)为技术支撑,确定了轴心的辐射范围,构建了上海为一级轴心,南京、苏州、无锡、杭州、宁波为二级轴心的三个层次的区域物流网络;并对各个重点物流枢纽的职能定位与发展方向作了相应的分析.
This paper summarizes and summarizes the research of regional logistics network, and analyzes the connotation of the hub-spoke servo network and its comparative advantage in the construction of regional logistics network.According to the current situation of regional logistics development in the Yangtze River Delta, In the region, there are some problems such as unreasonable network layout, unclear levels and so on. The index evaluation system of logistic central index is designed and the first-level hub and second-level hub of the network are established. Considering the urban It is difficult to acquire the data of the logistics intensity. The author uses the transportation cost as the condition for constructing the network. Taking the potential energy as the operation principle, through the potential difference of the logistics cost in the area, namely the transportation cost between each node and the axis, And the network construction and optimization are realized. Based on GIS network analysis method (grid algorithm) as technical support, the radiation range of the axis is determined and Shanghai is set as the first axis. Nanjing, Suzhou, Wuxi, Hangzhou and Ningbo Second-level axis of the three levels of the regional logistics network; and various key logistics hub function positioning and development direction made the corresponding analysis.
