Global Innovation Index S&T Cluster Ranking: Chennai, India Sees 7.8% Growth

A key factor shared by top-performing countries is the existence of robust science and technology (S&T) clusters. GII top-100 S&T Cluster ranking looks closer to the ground - using patent filing and scientific publishing data to identify local concentrations of world-leading science and technology activity.

Launched at IP Week @ SG 2024, a prominent annual intellectual property event organized by the Intellectual Property Office of Singapore, the GII S&T Cluster ranking reveals that seven of the top 10 science and technology clusters are located in Asia, with the remaining three in the United States.

Clusters within China once again demonstrated significant increases in S&T output in 2024. China hosts the two fastest growing clusters globally – Hefei (+22.7 percent) and Zhengzhou (+18.9 percent). Hefei’s growth was driven by a strong PCT applications growth. Cluster ranking 73 Clusters located in other middle-income economies besides China also experienced strong S&T output growth. Cairo (Egypt) had the highest growth rate for this group at 10.9 percent. Chennai (India) with 7.8 percent and Istanbul (Türkiye) with 7.5 percent also had a high rate of growth for this group.
