摘要
以西部地区132个地级市的物流发展情况为研究对象,基于Kendall协同系数以及Broad方法对熵权法、主成分分析法和灰色关联分析法三种方法的结果进行组合评价,借鉴辐射模型计算地级市间的货物流通量,然后运用社会网络分析方法对该物流网络的空间结构特征进行分析。结果表明:西部地区物流网络密度小,节点间物流联系程度较低;重庆、成都等个别节点物流中心度大,大多数节点物流中心性差异不大;物流网络中存在凝聚子群,子群内部以及子群之间的密度较小,表明物流网络具有一定的脆弱性。因此,需要突破地理位置的行政性束缚,充分发挥中转集散枢纽的辐射带动作用,大力加强凝聚子群之间的互动,以便实现西部地区物流协调发展。
Taking the logistics development of 132 prefecture level cities in the western region as the object of study,and based on Kendall synergy coefficient and broad method,the results of three methods of entropy weight method,principal component method and grey correlation method are evaluated combinatorially and the radiation model is used to calculate the goods circulation.Then the spatial structure characteristics of the logistics network are analyzed through social network analysis.The results show that the logistics network density is small in the western region,and the degree of logistics connection between nodes is low;the nodes such as Chongqing,Chengdu are large in terms of logistics centrality,and the logistics centrality of most nodes is not significant.There are condensed subgroups in the logistics network,and the density between subgroups and subgroups is small,which indicates that the logistics network has some fragility.Therefore,we need to break through the administrative bondage of geographical location,give the full play to the radiation driven role of the transit hub,and strengthen the interaction between the agglomeration subgroups,so as to realize the coordinated development of the western region logistics.
