黄河下游城市群信息网络空间结构研究
Research on the spatial structure of information network in urban agglomeration of the lower Yellow River
摘要
Abstract
Based on the 2021 intercity information attention data and social network analysis method the spatial structure characteristics of the information network of the Yellow River downstream urban agglomeration was studied from many aspects,such as network hierarchy,urban nodes,spatial clustering,and spatial organization mode,and proposesa high-quality collaborative development strategy for the Yellow River downstream urban agglomeration.Results show that:the hierarchical distribution of information connections in urban agglomerations in the lower reaches of the Yellow River has obvious hierarchical and distance attenuation characteristics,forming a"core radiation structure"centered around regional central cities-Zhengzhou,Jinan,and Qingdao;the degree centrality and proximity centrality of urban nodes in the lower Yellow River urban agglomeration present gradient differentiation,and the intermediate centrality shows a significant polarization phenomenon.Zhengzhou,Jinan,and Qingdao are always in the central position,while most cities in Shanxi,Hebei,and Anhui provinces are at the edge.The spatial clustering of urban clusters in the lower reaches of the Yellow River has regional proximity and is limited by provincial administrative boundaries to form"four major areas and eight clusters".The information network of the urban agglomeration in the lower reache of the Yellow River has formed a network organization model with Zhengzhou,Jinan,Qingdao as the core,Linyi,Weifang,Yantai,Luoyang,Handan,Nanyang,Xinxiang,and other secondary cores.关键词
