中文摘要：

网络嵌入性影响着企业知识的有效获取。现有研究对于这种影响更多的是从知识获取的最终效果这一综合整体角度入手分析的，使得研究结论难以统一。在对相关文献梳理的基础上，将知识获取分为搜寻、辨识、接收、创新四个阶段。从考察知识获取不同阶段的特征入手，实证分析亍关系性嵌入与结构性嵌入对企业知识有效获取的影响。研究表明，网络嵌入性对企业间知识获取效果的影响因阶段不同而表现出较大的差异性。

英文摘要：

Network embeddedness affects the validity of enterprise knowledge acquisition. Former related studies were mainly made integratively, focusing on the ultimate result of knowledge acquisition, which is difficult to obtain a consentaneous conclusion. In this paper, based on the review and analysis of former researches, knowledge acquisition is divided into four stages, including search, discrimination, receiving, application, and innovation.According the characteristics of the four stages of knowledge acquisition, the effects of relational embeddedness and structural embeddedness upon enterprise knowledge acquisition are analyzed and discussed by using the method of demonstration.The result shows that, when knowledge acquisition takes place at different stages, the effects of network embeddedness upon the knowledge acquisition display a remarkable difference.
