企业创新网络中，外部知识的获取分为联盟型知识获取和市场型知识获取两种形式。通过对企业外部知识与双元性创新的关系进行深入分析，揭示不同类型的外部知识对双元性创新的不同影响，以及网络位置在上述过程的调节效应。文章采用多元线性回归方法，利用175份企业有效样本数据进行实证分析。结果表明联盟型知识获取和市场型知识获取对双元性创新都有显著的影响，联盟型知识获取对突破式创新的影响程度较大；网络位置正向影响市场型知识获取和突破式创新之间的关系以及联盟型知识获取与渐进式创新的关系。

英文摘要：

In enterprise innovation network, the external knowledge acquisition is divided into two modes which are alliance knowledge acquisition and market-oriented knowledge acquisition. Based on the in-depth analysis of the relationship between the enterprise external knowledge and ambidexterity innovation, this paper reveals the different impacts of different types of external knowledge on ambidexterity innovation, and explores the moderating role of network position. The paper uses the muhiple linear regression method and takes available data of 175 enterprises for the empirical analysis. The result shows that the alliance knowledge acquisition and market-oriented knowledge acquisition has significant effect on the ambidexterity innovation, and the influence of the alliance knowledge acquisition for breakthrough innovation is much bigger. Network position positively affects the relationship between the market-oriented knowledge acquisition and breakthrough innovation as well as the relationship between the alliance knowledge acquisition and incremental innovation.
