| The coordinated development of regions is constantly advancing,and the elements between regions are frequently exchanged.As the basic industry of economic development,logistics promotes the rationalization of the industrial layout of the whole region.The central region is connected with the southeast and northwest,it has obvious regional advantages.Its high-quality coordinated development is also an important factor for the rise of the central region.By constructing the evaluation system of logistics development level in central China,this dissertation uses entropy weight method to measure the regional logistics development level of 82 prefecture-level cities in 6 provinces in central China.Then,the gravity model is used to construct the logistics network in central China,and the structural characteristics of the logistics network are analyzed by social network analysis.Finally,the hub-and-spoke core logistics network is constructed based on mean clustering and logistics membership function.The main contents of the dissertation are as follows:(1)Logistics development level evaluation and spatial pattern evolution in central China.Based on the existing research results,taking the development and location characteristics of the region into full consideration,the evaluation index system of logistics development level in is constructed by using principal component analysis method,and the entropy weight method is used to measure the regional logistics development level of each city,and analyze the spatial pattern evolution characteristics of logistics development level.(2)Logistics spatial connection network analysis in central China.The gravity model is used to establish the logistics spatial connection network in central Region,and using the maximum gravitational line and space connection potential energy to analyze the space-time evolution trend of the connection network.Finally,based on the social network analysis model,the dissertation explores the network density,centrality and cohesive subgroups of logistics network,and analyzes the role of each city in the logistics spatial network.(3)Build hub-and-spoke logistics network in central China.Based on spatial features of logistics development in central China and contact network structure,selection of the urban logistics development and logistics contact potential energy as a variable,using the K-means clustering to determine the central axis of the city of regional logistics network,and then logistics membership function is used to determine the axis of the city’s radiation scope,considering the related factors affecting the development of logistics in central China,The channel of logistics network is analyzed,and finally the hub and spoke core logistics network in central China is constructed to promote the better development of logistics in various cities. |
