Reference News reported on August 10According to a report by Japan's Sankei Shimbun on August 10, the gap between the number of "papers of interest" in Japan and those in China and South Korea has widened.

On the 9th, the Institute for Science and Technology Policy of the Ministry of Education, Culture, Sports, Science and Technology of Japan released a report titled "Science and Technology Indicators 2024", analyzing the scientific research trends of major countries such as Japan. Although Japan's R&D expenditure and number of researchers remain third in the world, and the total number of papers remains fifth, the number of papers that have received high attention is still ranked 13th, the lowest in history since last year, lower than South Korea and Iran.

The Institute for Science and Technology Policy analyzed papers published between 2020 and 2022 and counted the number of papers ranked in the top 10% in terms of citations in each field.

Japan published an average of 3,719 such papers per year in the three years mentioned above, 13 fewer than last year's statistics. Japan's data has been hovering at this level in recent years and may have hit bottom.

China and the United States still ranked first and second, while South Korea surpassed France and rose to ninth place. The gap between Japan and China and South Korea further widened.

However, the proportion of Chinese "notable papers" cited by domestic papers is as high as 62%, far exceeding the 24% of the United States and 10% of Japan, and is also the highest among the 25 major countries. Analysts pointed out that the fact that most Chinese papers are cited by domestic scholars may be one of the reasons for its high ranking. (Compiled by Li Ziyue)
