Spatial Layout&Network Structure of Logistics Links in New International Land-Sea Trade Corridor
In order to explore the change of spatial layout of logistics links in 13 provinces of New Interna-tional Land-Sea Trade Corridor and the evolution law of network structure of logistics links,from the per-spective of spatial connection,13 provinces(autonomous regions,and municipalities)in New International Land-Sea Trade Corridor were taken as research objects,the gravity model was selected to construct the lo-gistics connection network of New International Land-Sea Trade Corridor.The total density,centrality and cohesive subgroups of the logistics connection network were measured by SNA(Social Network Analysis).Then,the characteristics of the spatial layout and network structure of the logistics connec-tion in New International Land-Sea Trade Corridor from 2010 to 2020 were analyzed.The results showed that:(1)In 2020,there were significant differences in the logistics quality values of the 13 provinces(autonomous regions,and municipalities)in the New International Land-Sea Trade Corri-dor,with prominent quality in the central region;(2)From the perspective of spatial connection,during the period of 2010-2020,the distribution pattern of the maximum gravitational line of logistics in the new corridor region was basically stable,the maximum gravitational value among the 13 provinces(au-tonomous regions,and municipalities)continued to increase,and the increase of the maximum gravi-tational relationship in the south was significantly higher than that in the north,and the spatial distribu-tion of logistics connections showed a"lightning"pattern,while developing from a"single core"to a"multi-core";(3)The logistics connection network was stable on the whole,with local dynamic insta-bility,among which Shaanxi Province occupied the core position of the network structure,which was the key location of logistics development in New International Land-Sea Trade Corridor.
