China overtakes US in high-quality scientific research, says study

US lawmakers passed the $280 billion CHIPS and Science Act out of a fear that China was about to overtake the US in scientific and technological expertise. But a recently released study suggests that, by one measure, China already has.

On Tuesday, Japan’s Science and Technology Ministry released a report showing that 27.2% of the top 1% of most-cited papers in 2019 came from Chinese institutions. (How often a paper is cited by other scientists and researchers is considered a measure of its quality.) The US came in second place, releasing 24.9% of the top 1% of most-cited papers.

Earlier reports from Japan’s Science Ministry show that China was already beating the US when it came to the number of papers published. In 2020, the ministry said China had published 305,927 papers (or 19.9% ​​of the total), compared to the US’s 281,487.

But now China appears to have topped the US in quality, not just in quantity, of scientific research.

The speed at which China has caught up to the US is a result of the country’s goal to become a world leader in tech by 2050.

Chinese President Xi Jinping has prioritized investments in research and development in an effort to make China more self-sufficient, rather than relying on imports of advanced technology from overseas. The country spent a record $441.3 billion on research and development in 2021. (The US spent $664 billion in 2020, according to the Organization for Economic Co-operation and Development). In July, the Aspen Institute, a US think tank, predicted that China would overtake the US in R&D spending by 2025.

China’s growing R&D heft motivated lawmakers to pass the CHIPS and Science Act, signed into law on Tuesday. “Other countries are closing in fast” on the US, said President Joe Biden during the Act’s signing ceremony.

The Act offers $280 billion in incentives to encourage US research and development, including $52 billion in subsidies to support US semiconductor manufacturing. The act also prevents chip companies that receive US subsidies from expanding production of advanced chips in China, leading chipmaking companies like Samsung and SK to Hynix reportedly consider moving production elsewhere.
