  When a publication is cited it generates a benefit. Through the country
affiliations of the citing authors, it is possible to work upwards, tracing the
countries that benefit from results produced in a national research system. In
this work we take the knowledge flow from Italy as an example. We develop a
methodology for examination of how the knowledge flows vary across fields, in
each beneficiary country. We also measure the field comparative advantage of
countries in benefiting from Italian research. The results from this method can
inform bilateral research collaboration policies.
