产业集群如何升级？服务业与集群制造企业互动是否是产业集群升级的有效路径？为回答这样的问题。本文试图探究知识密集型服务业嵌入到产业集群之后在其中所承担的角色及其发挥的功能。论文运用社会网络分析方法和案例动态演绎方法，以浙江大唐袜业产业集群为例．实证了2003--2007年5年时间跨度中知识密集型服务机构的嵌入过程．及其对集群整体网络密度、网络中介性与网络凝聚性三个网络结构指标的作用，系统揭示知识密集型服务机构对集群网络结构的影响及其演化动力因素．以期为发展知识密集型服务业促进产业集群升级提供理论支持。

英文摘要：

This paper employs longitudinal case study research to investigate how KIBS embedding impacts the evolution of industrial cluster＇s network structure. The paper answers these intrinsic research questions by examining the network evolution process of Datang socks cluster under the influence of KIBS embedded from 2003- 2007. Initially, in order to explore the functional mechanism, KIBS embedding process of each development phase has been analyzed. Next, SNA and UCINET software have been used to unveil the process of the change of cluster network structure, such as network density, network betweenness centrality and network agglomeration. Finally, we summarize the KIBS＇ functional mechanism by KIBS＇ ability to influence some important variables and optimize cluster network structure, which provides solid advice to policy makers.
