Abstract: As innovation plays an increasingly important role in firm growth and sustained competitive advantage, many firms are engaged in multiple partnerships, forming or enter portfolios of alliances. Alliance Portfolio which are commonly defined as ego-Centered network organization, that are comprised of not only a focal firm’s direct ties to each of its alliance partners, but also its indirect ties to partners of the firm’s direct partners. Previous research has shown that many of the dimensions of alliance portfolio emergence, diversity, performance, configuration and management. But has few analyzed how alliance portfolio network dimensions affect innovative capability. In fact, our review of the literature by establishing a comprehensive of alliance portfolio that incorporates network characteristics, focused on network status, network relationship, resource flow, governance and hypotheses were tested these constructs with respect to innovation capability. Results from the data analysis show that network status and network relationship has a significant influence on resource flow and governance, positive effects on innovation capability. The results also indicate that resource flow has significant impact on innovation capability. But under different network type of Alliance Portfolio ratio coefficients between governance and innovation capability significantly change, density increased in network can cause loss of efficient.

摘要： 联盟组合是一个以焦点企业核心的自我中心网络组织，是企业提高创新能力和实现持续竞争优势的关键。现有的研究对联盟组合网络特征与创新能力之间的关联尚缺乏系统、深入的研究；而联盟组合企业间的相互嵌入具有“网络化”的特征，兼具结构与关系的特点。本研究在对相关文献回顾的基础上，构建了联盟组合网网络特征与创新能力之间的理论模型，并提出了相应理论假设。在此基础上，通过大样本问卷调查和实证分析对理论模型及假设进行检验。研究表明：网络地位及网络关系通过资源流动、控制治理来间接影响创新能力。资源流动对创新能力具有显著正向影响；而在不同网络类型的联盟组合中，控制治理对创新能力的显著影响会随着网络密度增加而下降。
