中文摘要：

本文以资源依赖理论为支撑，基于社会网络与相关统计分析方法，构建了中国10个高科技行业的大规模联盟创新网络，研究了嵌入网络的420个上市公司的网络嵌入性与地域根植性对其创新绩效的影响。结果表明，个体中介中心性与行业网络密度对嵌入企业的创新绩效都有显著的正向影响，但中介中心性的影响具有明显的滞后效应；企业所在区域位置对其创新绩效的影响不显著，但企业的区域位置对联盟网络密度影响创新绩效具有调节效应，不在三大经济圈内的企业所在行业的网络密度对其创新绩效的影响消失。这些结论为相关政府部门制定联盟政策和企业开展联盟活动提供了科学依据。

英文摘要：

Supported by the resource - based view and based on the social network and relevant statistical analysis method, we built up a large - scale alliance innovation network of 10 high - tech industries in China, and studied the 420 listed companies as sample to explore the impact of network embeddedness and geographic embeddedness on their innovation performance. The results demonstrated that the centrality of the individual intermediary and the industrial network density have significant positive influ- ences on the enterprise＇s innovation performance, but there is an obvious lag effect on the part of the intermediary centrality. We also found out that the geographic location of an enterprise is not related to its innovation performance, but the location has a sig- nificant moderating effect on the relationship between the network density and the innovation performance. Specifically, the influ- ence of the network density on the enterprise＇ s innovation performance will disappear if the enterprise is located outside the three economic circles. These conclusions will provide new scientific basis for the development of relevant industrial policies and con- ducting of the alliance activities.
