中文摘要：

本文以中国通讯设备行业的联盟创新网络作为样本，在网络密度对创新绩效影响的基础上，为企业赋予地理位置上的动力学特征，采用负二项回归的方法，研究企业的区域位置以及企业间的地理邻近性与网络密度的交互作用对创新绩效的影响．结果表明，地理邻近性对创新绩效影响显著，企业坐落在三大经济圈对创新绩效的影响并不显著，而且企业间地理邻近性能够正向调节网络密度对创新绩效的影响．基于此，文章进一步结合中国通讯设备行业联盟的现状进行了分析，并提出了相关建议．

英文摘要：

Taking alliance innovation network in the Chinese communication equipment industry as samples, based on the impact of network density on innovation performance, it gave firms dynamic characteristic in the geographical position to study the impact of regional location and the interaction between geographic proximity and network density on innovation performance. The results indicate that regional location doesn＇ t have a significant effect on innovation performance, while geographic proximity has a significant effect on innovation performance ; geographic proximity can positively moderate the impact of network density on innovation performance. Then it further analyzed some conditions concerning alliances of Chinese communication equipment industry and offered some related suggestions.
