区域性中小产业集群企业网络研究——以民权制冷产业集群为例

Research on the Enterprise Network of Regional Small and Medium Industrial Cluster——A Case Study of the Refrigeration Industrial Cluster of Minquan County

以河南省民权县制冷产业集群为研究案例,通过调研获取企业间的正式与非正式联系数据,提取集群内2013年、2017年的经济联系、技术合作、社会交流企业网络,基于社会网络分析方法(SNA)分析区域企业网络结构,判别集群的发育水平和特点。研究发现:(1)区域性中小产业集群往往具有比较典型的马歇尔式产业区特征;(2)企业网络发育不平衡,整体连通能力不强,产业链条和配套网络还不够完善;(3)社会资本在企业网络构建中发挥了重要作用,也使集群面临着"锁定"的风险;(4)网络中介节点具有较强异质性,部分低度值节点因扼守关键位置也具有较强的中介作用。

This paper takes the refrigeration industrial cluster of Minquan county in Henan Province as a typical case and collects formal and informal contact data between enterprises through investigation. Data of the economic relation,technical cooperation and social communication enterprise network in 2013 and 2017 is extracted from the cluster. Then the paper analyzes the regional enterprise network structure and distinguishes the development level and characteristics of the cluster through social network analysis method（ SNA）.The results show that： 1） Generally,the regional small and medium industrial cluster exhibits typical characteristics of the Marshallian district. 2） The development of the enterprise network is unbalanced,with a low overall network connectivity and underdeveloped industrial chain and supporting network. 3） Social capital plays an important role in the construction of regional enterprise network,but puts the cluster at the risk of ＂being locked＂in the meantime. 4） The intermediary nodes of the network have strong heterogeneity,with some low degree value nodes showing strong mediating effect due to their important position.
