Do more distant collaborations have more citation impact?
作者：
Highlights：
• We address question whether systematic differences exist between pairs of collaborating countries in terms of the citation impact of their joint output.
• We find that citation impact increases with the geographical distance between the collaborating counties.
• Country-specific effects on citation impact are also substantial.
• We find no effect of language and interdisciplinarity on citation impact.
