Inside Hunan University's largest research partnership: Central South University

Behind Hunan University's research output sits a defining relationship: 3,932 co-authored works with Central South University (China) in the five years to 2025, the university's single largest collaboration.

It anchors an unusually connected research base: 900 collaborating institutions across 66 countries, producing 41,670 joint works over the window, with international co-authors on 22% of output.

The collaborative work travels: its field-weighted citation impact stands at 3.18, where the world average is 1.0.
