Zhengzhou University's research now spans 70 countries

Research at Zhengzhou University is a global undertaking: the university co-authors with 1,015 institutions in 70 countries, and international collaborators appear on 18% of its output.

Its largest single research relationship is with Peking University in China, at 2,318 joint works. Across the network, five-year output reaches 62,790 co-authored works.

Connectivity of this kind is increasingly the currency of modern science, and it is measurable: the open scholarly record makes every one of these relationships public and checkable.

The Research Collaboration Index, the first global account of how universities actually collaborate, publishes its first full edition on Tuesday 15 September at 09:00 UK.

Every figure derives from the open global research record and is checkable at source.
