R&D collaboration networks enable rapid access to global sources of knowledge, especially in strongly knowledge-based and technology-driven industries. However, technological idiosyncrasies require a refined picture, in particular, when explaining the interplay between geographical and relational effects driving the constitution and dynamics of R&D collaboration networks. We employ a spatial interaction modelling approach to estimate how geographical separation and network structural effects influence technology-specific R&D collaborations between European regions. The results underline both the significance of geographical barriers and network structural effects and confirm that specific network connectivity is able to compensate for geographical barriers—throughout all technologies investigated, although the effects differ in magnitude. However, when two regions are dissimilar in their network centrality, the potential to reduce negative geographical effects is relatively lower.

地理或关系：什么驱动特定于技术的研发协作网络？

研发协作网络可以快速访问全球知识资源，尤其是在以知识为基础且以技术为主导的行业中。但是，技术特质要求有一张清晰的图片，尤其是在解释驱动研发合作网络的构成和动态的地理和关系效应之间的相互作用时。我们采用空间相互作用建模方法来估计地理隔离和网络结构效应如何影响欧洲区域之间特定于技术的研发合作。结果强调了地理障碍和网络结构效应的重要性，并确认特定的网络连通性能够弥补地理障碍-在所研究的所有技术中，尽管效果的大小不同。但是，当两个区域的网络中心性不同时，减少负面地理影响的潜力相对较低。
