现代物流业作为中部地区的支柱产业,对其经济发展起带动作用,物流网络的科学构建则关系到经济空间格局的走向。通过建立物流网络指标评价体系,分析得到各研究单元的物流综合实力评价指数,确定不同等级的轴心城市,根据加权平均旅行时间测度节点到物流中心的时间成本,选用潜力模型划分轴心城市辐射范围,构建了中部地区"轴—辐"物流网络体系。研究发现:中部地区已经形成以武汉为一级轴心城市,长沙、合肥、郑州、南昌、太原为二级轴心城市,芜湖等19个地级市为三级轴心城市,其他地级市(州)和县级城市为边缘物流城市的物流网络。从物流网络的影响范围来看,各省辐射范围基本与行政界线相吻合,区域内节点与轴心之间联系紧密;从分区域来看,物流网络存在着发展不平衡、区域联系不紧密等问题。
Modern logistics industry plays a pivotal role in driving economic development in the central region of China. Thus, establishment of a scientifically proven logistics network would have a significant impact on the spatial pattern of economic structures of the region. A capacity assessment system is introduced for the logistics network in central China, evaluation analysis is conducted to acquire a comprehensive logistics capacity index value for each unit area in the study, and the hub cities of different levels are identified in the network. Then, the time cost of transportation from a node to a logistics center is calculated using weighted average travel time. Based on the potential model, the coverage areas of the hub cities are determined, leading to the layout of the hub-and-spoke logistics network for the region. This study indicates that the logistics network has already been formed in central China, with Wuhan as the first-level hub, Changsha, Hefei, Zhengzhou, Nanchang, Taiyuan as second-level hubs, Wuhu and other nineteen cities as third-level hubs, and the rest of prefecture-level and coun- ty-level cities as peripheral cities. In terms of the impact of the logistics network on central China, the coverage areas of the network match well with the administrative boundaries of the provinces, and nodes are closely tied to hubs. However, problems remain on issues like unbalanced development of the logistics network among the areas and loose connections between the areas.
