“互联网+”背景下浙江省城际货运时空网络演化及驱动机制

Spatio-Temporal Evolution and Formation Mechanisms of Intercity Freight Network in Zhejiang Province Under the Background of“Internet plus”

基于专业货运信息平台上的货运大数据,运用大数据分析与复杂网络分析,对“互联网+”背景下浙江省城际货运时空网络演化规律及驱动机制进行研究。结果表明:①宁波与舟山形成新的“双核心”网络。②点度中心度货运网络最能反映地理空间城市货运结构演化规律。③不断增加的长程联系是驱动时空网络演化的内部驱动力。④宁波和舟山在货运网络中形成日益突出的规模辐射效应,成为推动网络联系不断增强的内部动力。⑤时空网络演化主要受经济驱动和人力资源因素的推动,且具有较强的工业经济偏好依附机制,但外部驱动因素影响总体呈现减弱趋势。⑥通过功能互补网络促进“飞地经济”体系形成,优化城际货运网络布局。

Based on the freight transport big data on the freight information platform,this study used big data analysis and complex network analysis to explore the evolution rules and driving mechanisms of the spatio-temporal network of intercity freight in Zhejiang province under the background of"Internet plus".This study revealed that:1)Ningbo and Zhoushan established a new"dual core"network.2)The degree centrality freight network can best reflect the evolution rules of the intercity freight structure in geography.3)Increasing long-range connections were internal driving forces which drive the evolution of spatio-temporal networks.4)Ningbo and Zhoushan form an increasing prominent radiation effect of scale in the freight network,which became the internal force to strengthen network connections.5)The evolution of spatio-temporal network was mainly driven by economy and human resources,and had strong attachment mechanism of industrial economy preference.The influence of external driving factors were decreasing from 2011 to 2018.6)We should promote the formation of"enclave economy"system through functional complementary network and optimize the intercity freight network layout.
