Abstract: The paper takes Sony’s technological alliance networks from 1995 to 2011 as the case, investigating the fit between different types of alliance networks and knowledge management motives. Firstly, based on the characteristics and types of social network, the paper develops four hypotheses respectively regarding the fit between weak ties, strong ties, standard alliance networks and knowledge acquisition, explorative knowledge sharing, exploitative knowledge sharing and knowledge commercialization. Then the paper analyzes that licensing, equity joint ventures, collaborative agreements, and standard alliance networks are associated with different knowledge management motives. Finally, the paper concludes with managerial implications on importance of the role of organizational boundary spanners, improving the fit between alliance networks and knowledge management motives, and enhancing the alliance network management capabilities.

摘要： 以索尼公司1995~2011年的技术联盟网络为对象，考察了索尼与其他公司建立的联盟网络类型与知识管理动机之间的匹配关系。首先，基于社会网络的结构特征与类型，提出弱联系、强联系和标准联盟网络与知识获取、探索型知识共享和利用型知识共享、知识商业化之间的匹配假设；其次，通过对研究变量的操作化定义，分析了许可证、股权合资、合作联盟、标准联盟网络与知识管理动机之间的匹配性。最后从重视边界管理者的作用、提高联盟网络类型与知识管理动机的匹配性以及提升联盟网络管理能力等方面提出了管理启示。
