流空间视角下江苏省物流联系格局演化研究

Research on the Evolution of Logistics Linkage Pattern in Jiangsu Province from the Perspective of Flow Space

在物流作用下城市间的联系日益密切,促使现有经济活动由场所空间向流空间转换.从经济发展水平、物流规模水平、基础设施支撑、物流专业化水平4个维度构建物流业发展的综合指标评价体系.运用主成分分析和综合加权法对江苏省13个地级市2003、2008、2013和2017年4个年份的物流发展水平进行测算,运用修正后的引力模型测算城市间的物流联系强度.研究结果表明:江苏省各城市的物流综合水平稳步上升,城市间差异明显,大体呈现“南强北弱”的空间格局,且城市间差异持续增大;城市间物流联系呈现苏南地区物流联系紧密,苏北地区联系相对较弱,苏南各城市物流联系逐渐由点轴式发展为网络式结构;基于流空间视角发现江苏省呈现多物流中心,物流网络联系的空间差异性逐渐增大,逐渐形成以苏州-无锡-常州为轴线和以南京-镇江-扬州-泰州为轴线的分布于苏南地区的两个发展轴.最后针对江苏省城市间物流发展水平与联系差异提出对策建议.

Under the action of logistics,the connection between cities becomes increasingly close,which promotes the transformation of the existing economic activities from the field intensity space to the flow space.Firstly,a comprehensive index evaluation system is constructed from the four dimensions of economic development level,logistics scale level,infrastructure support and logistics specialization level.Based on the comprehensive weighted principal component analysis and evaluation of 13 cities in Jiangsu province in 2003,2008,2013 and 2017,four years,logistics development level of the revised based on the gravity model to explore the logistics space contact strength.Logistics comprehensive level of the cities in Jiangsu province rising steadily,clear difference between city presents us"strong in the South and weak in the North"spatial pattern,and the differences between the city continues to increase.Inter-city logistics links show that the logistics links in southern Jiangsu are close,while those in northern Jiangsu are relatively weak.The logistics connection of cities in southern Jiangsu gradually developed from point to axis to network structure.Based on the perspective of flow space,it is found that Jiangsu province presents multiple logistics centers,and the spatial difference of logistics network connection is gradually increasing.At the same time,the logistics network system gradually forms two development axes distributed in southern Jiangsu with Suzhou-Wuxi-Changzhou as the axis and Nanjing-Zhenjiang-Yangzhou-Taizhou as the axis.Finally,in view of the differences in the development level and network connection of logistics among cities in Jiangsu province,this paper puts forward three Suggestions:relying on the regional advantages,promoting the rapid development of logistics,building urban logistics circle,promoting the coordinated development of logistics,strengthening infrastructure construction,and promoting the integrated development of logistics.
