Abstract: Based on social network theory, resource-based view and the growth curve model, the effects of intra-community structure dynamics (intra-community stability, intra-community expansion) and inter-community structure dynamics (inter-community expansion) on enterprises’ innovation performance in the innovation network under different technology life cycle stages are investigated. Using SDC database, USPTO, JPO, EPO and the national patent database of the sample enterprises, the empirical research is carried out with the alliance enterprises in the field of communication equipment as samples. The results show that in the technological emerging period, inter-community expansion have a negative impact on innovation performance; in the technological growth period, inter-community expansion and intra-community stability has a positive impact on innovation performance; in the technological maturity stage, intra-community stability has a positive impact on innovation performance, while intra-community expansion and inter-community expansion have a negative impact on innovation performance. On this basis, the paper puts forward policy suggestions to improve enterprises’ innovation performance by adjusting the innovation cooperation network in different life cycle stages.

摘要： 基于社会网络理论、资源基础观和成长曲线模型，考察不同技术生命周期阶段下企业在创新网络中的社群内结构动态（群内稳定、群内扩张）和社群间结构动态（群间扩张）对企业创新绩效的影响。运用SDC数据库、USPTO、JPO、EPO以及样本企业所在国家专利数据库，以通信设备领域的联盟企业为样本进行实证研究，结果表明在技术导入期，企业群间扩张对创新绩效有负向影响；在技术成长期，企业群间扩张以及保持群内稳定对创新绩效有正向影响；在技术成熟期，企业群内稳定对创新绩效有正向影响，群内扩张与群间扩张对创新绩效有负向影响。在此基础上，提出不同生命周期阶段企业通过调整创新合作网络以提升企业创新绩效的政策建议。
