多核式中卫型产业集群的网络结构分析--以沈阳装备制造业集群为例

“单核式”与“多核式”是中卫型产业集群的两种基本网络结构。以多核式中卫型产业集群作为研究对象，对其进行概念界定，指出其网络结构具有多个中心结点、内部合作关系密切、结点凝聚成小团体、中心结点相互关联等特征，并据此选取了社会网络分析方法中的中心性、黏性、凝聚子群、核心边缘结构作为网络结构指标。运用这些指标，对沈阳装备制造业集群的网络结构进行了实例分析。研究发现：该集群网络中，各产业部门的核心企业充当了中心结点，同一产业部门的企业密切合作组成凝聚子群，核心企业之间关联紧密形成核心区。这些网络结构特征是其获取生产协作、资源配置和知识创新等竞争优势的重要保证。针对该集群网络黏性较低的现状，最后提出相应的网络结构优化建议。

Research on Network Structure Properties of Central Satellite Industrial Cluster with Multi-core:A Case of Shenyang Equipment Manufacturing Industrial Cluster

Single-core type and multi-core type are two basic network structures of central satellite in-dustrial cluster. This article takes central satellite industrial cluster with multi-core as research object,defi-ning its conception,and pointing out its network structure properties of having multi central nodes,dense in-ternal cooperation,small groups and interacted central nodes. According to the properties,network structure indexes of centrality,viscosity,subgroup and core-periphery structure are selected. By applying these inde-xes,the network structure of Shenyang equipment manufacturing industrial cluster is analyzed. It is found that,in this cluster network,core firms act as central nodes,firms within the same industry sector cooperate tightly,core firms related to one another form the core area,which help the cluster to attain competitive advan-tages of production collaboration,resource allocation,and knowledge innovation. In view of the cluster network＇s low viscosity,this article puts forward network structure optimization propositions.
