中文摘要：

对网络嵌入作用的主流研究中，具有越来越注重情境化的趋势。以原生型集群企业为研究对象，考察了其嵌入的两种重要网络类型：商业网络和技术网络，并将企业规模的差异作为重要的情境变量，纳入到分析网络关系强度对企业创新能力作用的研究中。通过实证分析发现，集群内外的商业网络和技术网络的关系强度，对集群内大企业和中小企业的探索性和利用性创新的作用具有显著差异，在作用方向和程度上亦有明显区别。

英文摘要：

The role of network embeddedness research have increasingly focused on the contingency in the main- stream. In this paper, we study firms in industrial cluster, which examined relational embeddedness inside and out- side clusters of two most important types of networks： business networks and technology networks, also we put finn size as an important contingent variable into the analysis of the relationship strength of the network effect to innovation. Through empirical analysis, the study found, roles of business networks and technology networks in- side and outside cluster have significant differences to innovations of large enterprises and SMEs in the direction and extent.
