| 摘 要： | 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.

| Abstract: | Undoubtedly, the rise of modern logistics will be great and particular significance to the development of our world. Modern logistics, as one of the new productive service industries, creates time value and the spatial value in every link of production, transportation and sale. At present, related research on regional logistics and logistics network mainly concentrate in the scope of small regions, and most studies focus on traditional transport manners and the impact of transport in the nationwide scope. In view of this, this paper attempts to construct a theory frame of logistics network from the scope of macroscopic scale. Taking the Yangtze River Delta as the examples, the authors try to give some advice to regional logistics and construct a logistics network in the Yangtze River Delta. Because of the current situation in the Yangtze River Delta that grade system is chaos, foundation of logistics is not constructed, the authors analyze the conception of regional logistics, and discuss its competitive advantage. On account of the confusion of the concept and network distribution of logistics in the Yangtze River Delta, the authors choose the estimation indexes to appraise hub cities in this region. Considering the intention between the cities was difficult to evaluate, the authors point out the effective region of the hub cities based on road traffic cost. Finally, the hub-and-spoke network is constructed in the Yangtze River Delta, and a concrete analysis is done on the main logistics cities about their orientation. |
