综合运输可达性与物流经济的空间分异及耦合

综合运输可达性与物流经济之间存在耦合关系.以丝绸之路经济带为例，基于省域层面的面板数据，利用ArcGIS 可视化平台，分析综合运输可达性及节点城市物流经济发展水平的空间分异特征；进一步解析综合运输可达性与物流经济的耦合协调机制，构建耦合协调度模型，分析综合运输可达性与物流经济的耦合协调发展格局.结果显示：整体空间上，综合运输可达性与物流经济发展水平的区域差异显著，均呈现“东高西低” 的空间分布格局；综合运输可达性与物流经济的协调发展度差异显著，且整体水平不高，丝绸之路经济带的综合运输基础设施实际投入和物流产出的匹配度有待提高，且对物流经济发展的支撑作用尚未充分发挥.

Spatial Differentiation and Coupling between Integrated Transport Accessibility and Logistics Economy

There is a coupling between logistics economic and integrated transport accessibility. Based on provincial-level panel data, this paper uses ArcGIS to evaluate the regional integrated transport accessibility and the logistics economic development of the city nodes in Silk Road Zone. On this basis, it gets the coordination mechanism between the integrated transport accessibility and logistics economy. A coordination degree model is constructed to obtain the coupling pattern of coordinated development of comprehensive transportation accessibility and logistics economy. The conclusion are: (1) As a whole, the level of integrated transport accessibility and logistics economic development is significantly different between regions and both of them show the spatial distribution pattern of“East High and West low”. (2) The level of coordinated development between integrated transport and logistics economic is low and obviously different. Meanwhile the actual input-output matching between Silk Road Economic Belt transport infrastructure and logistics needs to be improved, and its supporting effect for economic development is not yet fully.
