Proximity Matters: Analyzing the Role of Geographical Proximity in Shaping AI Research Collaborations
This addresses a gap in understanding individual-level collaboration dynamics in AI research, though it is incremental as it builds on prior work on geographical proximity.
The study analyzed how geographical distance affects individual-level AI research collaborations from 2001 to 2019, finding that it impedes collaboration despite technological advances, and that network proximity can substitute for geographical distance, with its effect increasing as distance grows.
The role of geographical proximity in facilitating inter-regional or inter-organizational collaborations has been studied thoroughly in recent years. However, the effect of geographical proximity on forming scientific collaborations at the individual level still needs to be addressed. Using publication data in the field of artificial intelligence from 2001 to 2019, in this work, the effect of geographical proximity on the likelihood of forming future scientific collaborations among researchers is studied. In addition, the interaction between geographical and network proximities is examined to see whether network proximity can substitute geographical proximity in encouraging long-distance scientific collaborations. Employing conventional and machine learning techniques, our results suggest that geographical distance impedes scientific collaboration at the individual level despite the tremendous improvements in transportation and communication technologies during recent decades. Moreover, our findings show that the effect of network proximity on the likelihood of scientific collaboration increases with geographical distance, implying that network proximity can act as a substitute for geographical proximity.
