The role of geographical proximity in knowledge diffusion, measured by citations to scientific literature
作者：
Highlights：
• We analyse the diffusion of knowledge produced in Italy in the period 2010–2012.
• We assign the prevalent territory of an article on the basis of the authors’ affiliations.
• Geographic distance continues to play a role in the process of knowledge flows.
• It is significant at the national level, and not negligible at the continental level.
• It is completely irrelevant at the intercontinental level.
