摘要
基于微观企业视角,选取100家装备制造业企业和长江经济带100个空间单元作为研究样本,借鉴城市网络研究方法以及复杂网络理论,探索长江经济带装备制造业网络的等级体系、空间格局、网络联系以及网络复杂性特征。研究表明:节点城市的网络组织能力差距明显,已形成区域性、次区域性、地方性以及次地方性4个层级所构成的金字塔型等级结构;装备制造业网络组织能力在空间上表现出显著的非均衡性特征,形成三大核心区,联系网络总体呈现出从长三角地区向长江中、上游地区逐渐拓展的趋势;同时整体网络结构表现出较强的集聚性、连通性,且复杂网络特征与城市网络地位具有显著关系。
From the micro-enterprise perspective,100 equipment manufacturing industries and 100 space units of the Yangtze River Economic Belt were selected as research samples. Based on the research methods of urban networks and the theory of complex networks,the hierarchical system,spatial pattern,network connections and complexity characteristics of the equipment manufacturing networks of the Yangtze River Economic Belt were explored. The research shows that there is a significant gap in the abilities of network organization of node cities,and a pyramidal hierarchical structure has been formed by four levels: regional,sub-regional,local,and sublocal. The organizational capabilities of the equipment manufacturing networks show significant unbalanced characteristics in space,which forming three core areas. The network of contacts generally shows a trend of gradual expansion from the Yangtze River Delta region to the middle and upper reaches of the Yangtze River. The whole structure of networks shows strong aggregation and connectivity,and there is a significant relationship between the characteristics of complex networks and the status of the urban networks.
