Inside Nanjing Agricultural University's largest research partnership: Zhejiang University

Behind Nanjing Agricultural University's research output sits a defining relationship: 1,020 co-authored works with Zhejiang University (China) in the five years to 2025, the university's single largest collaboration.

It anchors an unusually connected research base: 893 collaborating institutions across 67 countries, producing 29,563 joint works over the window, with international co-authors on 23% of output.

The collaborative work travels: its field-weighted citation impact stands at 3.34, where the world average is 1.0.
