Analysis
Data from the Nature Index has revealed 32 cities in mainland China are now recognized as major contributors to global scientific output. This positions them prominently within the global ranking of scientific cities, with ten Chinese cities making it into the top 20. The findings highlight China’s growing prominence in the international research landscape, showcasing an impressive increase in both the quantity and quality of research emerging from its urban centers.
According to the Nature Index 2024 Science Cities supplement, Beijing leads the global rankings. It is closely followed by Shanghai in second place, while Nanjing, Guangzhou, and Wuhan round out the top ten at fifth, eighth, and ninth places, respectively. Other notable mentions include Hangzhou (13th), Hefei (15th), Tianjin (18th), Hong Kong (19th), and Xi’an (20th). This remarkable achievement highlights China’s strategic investment in research and development across various fields.
The data indicates that half of the top 20 science cities are now located in China. This includes not only major metropolises but also provincial capitals like Chengdu and Hefei, which have emerged as competitive players on the global stage. Simon Baker, editor of the Nature Index supplement, noted, “This trend is particularly interesting as these lesser-known cities are now competing with established scientific hubs in Europe and North America.”
China’s research output has surged dramatically over the past decade, with a five-fold increase in published research between 2009 and 2021, outpacing that of Western nations. Notably, a recent report indicated China has surpassed the United States in producing highly cited papers, a key metric of research impact.
The rise of these cities aligns with China’s national strategies aimed at enhancing economic self-sufficiency and promoting high-tech industries. Initiatives such as “Made in China 2025” aim to shift the country toward knowledge-driven sectors, including electric vehicles and solar energy. As Baker noted in his article, “many of these rapidly developing cities are playing a specialist role in key technology areas such as electric vehicles and solar energy,” reflecting a broader trend of regional growth in scientific research.
Shanghai’s ascent to second place is particularly noteworthy as it has overtaken New York City, which now holds third place. This shift is attributed to Shanghai’s strengthening research capabilities in biopharmaceuticals, advanced materials, and artificial intelligence (AI). The competition among these cities is intensifying, with Beijing extending its lead over Shanghai to nearly double its share of scientific output to 18.4%.
Institutions contributing to this success include The Beijing Municipal Science & Technology Commission and the Administrative Commission of Zhongguancun Science Park, which have played vital roles in fostering an environment conducive to scientific advancement.
The implications of these findings extend beyond mere rankings; they reflect a broader narrative about China’s ambitions on the world stage. As the nation continues to invest heavily in education and research infrastructure, its cities are poised to play a pivotal role in shaping future scientific advancements.
Interestingly, while Chinese cities have made significant strides in various scientific fields, there remains room for improvement in health sciences. Currently dominated by established networks in cities like Boston and London, there is optimism that within a decade, leading Chinese cities could emerge as frontrunners in this domain as well.
In the pipeline, institutions that are expected to play a pivotal role in advancing research in various scientific fields – particularly in astrophysics and particle physics – include the Jiangmen Underground Neutrino Observatory (JUNO), which is currently under construction and will become the world’s largest and most sensitive neutrino observatory. Situated 700 meters underground, JUNO aims to address fundamental questions in particle physics. Another critical facility being built is the China Jinping Underground Laboratory, which, upon completion, will be the deepest underground laboratory globally, located 2,400 meters below the Jinping Mountains.
Baker said the emergence of provincial capitals signifies a shift in how scientific output is distributed across China.
“From Chengdu in the west to Hefei in the east, these cities are now rubbing shoulders with long-established scientific centers.” This diversification not only enhances regional development but also contributes to a more balanced distribution of research capabilities across the country.
The Nature Index tracks contributions from a select group of high-quality research journals and measures cities based on their share of published articles. This year’s rankings reveal Chinese cities are not only producing more research but are also enhancing their collaboration efforts both domestically and internationally.
It is clear China’s commitment to advancing its scientific capabilities will have lasting impacts on global research dynamics. With half of the top 20 science cities now situated within its borders, China is well-positioned to lead in various scientific disciplines over the coming years. By Nadia Shaw, MDT
