Recently, the World Intellectual Property Organization (WIPO) early-released the 2023 Global Innovation Index (GII) "science and technology clusters" ranking, revealing that all five top science and technology clusters are in East Asia with three in China. When the rankings extend to top 100, China is the country with the most clusters.
The data shows that in 2023, Tokyo-Yokohama (Japan) leads as the largest global science and technology cluster, followed by Shenzhen-Hong Kong-Guangzhou (China and Hong Kong, China), Seoul (Republic of Korea), China's Beijing and Shanghai-Suzhou clusters.
Science and technology clusters located in other middle-income economies besides China also saw strong science and technology output growth, notably in India which has 4 top science and technology clusters, with Chennai and Bengaluru experiencing the biggest increases in density of inventors and scientific authors. Science and technology clusters in certain emerging economies grew at a particularly fast pace, including Brazil, India, Turkey, and others.
