Share of international co-publications (international)
What percentage of a country's publications consist of international co-publications? In this data publication we show the share of scientific publications, where researchers in a country collaborate with researchers in other countries.
In short
- In this comparison Switzerland scores highest with an international co-production of 78,5%, the Netherlands scores on average with 70%.
- Japan, Korea and China score the lowest, with 37%, 36%, and 21% respectively.
- Also the US scores relatively low with 44%, which could be explained by the large domestic market of researchers with whom it is possible to collaborate.

Analysis
The percentage of international co-publications is quite diverse. The Netherlands scores average with 70% in this list. The USA, with 44%, scores low in this ranking, probably due to the large pool of national researchers with who researchers can collaborate. At the bottom of the list are Korea, Japan and China, where language may possibly play a role. For all countries, expect China, the percentage of co-publications in has increased over the years.
