中文摘要：

产学联盟中的企业同时处于地理位置和网络位置的双重空间中，具有空间二维性。本文在梳理国内外相关文献的基础上，从地理邻近和网络位置视角出发，对地理邻近、中心度、结构洞对产学联盟合作创新的独立影响以及地理邻近与中心度、地理邻近与结构洞的组合对产学联盟合作创新的交互影响进行实证分析。结果显示：地理邻近、中心度、结构洞均对产学联盟合作创新产生显著正影响；地理邻近与中心度对产学联盟合作创新产生显著交互影响且表现为互补关系；地理邻近与结构洞的交互影响并不显著。

英文摘要：

The enterprises in Industry-university alliance are both in the geographical position and network location, with a two-dimensional space. On the basis of carding the domestic and foreign relevant literature, this paper takes geographical proximity and network position as important factors. The empirical analysis is made to explore the independent effect of geographical proximity, centrality and structural hole, and clarify the interactive impact of geographical proximity and centrality, geographical proximity and structural hole. The result shows that geographical proximity, centrality and structural hole all have significant positive impact ; the interaction effects are showed between geographical proximity and centrality, by presenting a complementary effect. However, there is no signifi- cant interaction effect between geographical proximity and structural hole.
