中文摘要：

本文以关系、结构位势为维度分析集群内网络位势对知识扩散和创新的影响，认为丰富的网络关系资源扩大了单个集群企业知识搜寻的组织边界，并可以加快集群内知识扩散的速度与质量；占据有利网络位置的集群企业，自身享受网络位势利好的同时，能够为集群带来高质量差异化的创新资源。文章的理论分析和阐释，为我国建立区域创新系统、制定集群创新政策提供理论借鉴和参考，也为集群企业获取创新优势提供新的网络组织视角。

英文摘要：

This article analyzes the effects of network potentials on knowledge distribution and innovation from the perspective of both the relationship and structure potential dimensions. The resuhs suggest that rich relationship expand the organization boundary of single cluster enterprise in their process of searching knowledge and information. Rich relationship can speed up the knowledge diffusion process and improve the quality within a cluster as well. The cluster enterprise with the advantage position in the cluster network will en- joy the favorable factors of the network. They will obtain the high quality and heterogeneity resources which will benefit the innova- tion. Theoretical analysis and interpretation of this article will provide the theoretical proposal for the regional innovation system and the decision-making policies of cluster innovation. This article also provides a new perspective of network organization for the cluster enterprise acquiring innovation advantages.
