It was followed by the U.S. with 59,570, Japan with 50,260, South Korea with 20,678 and Germany with 17,322.

Zhejiang University ranked second, followed by Tsinghua University ranking fourth, South China University of Technology ranking seventh and Soochow University ranking ninth. The top 50 universities list had 19 Chinese universities, including Shenzhen University.
