PUBLISHED SCIENCE & ENGINEERING (S&E) ARTICLES – U.S. RANKING
R&D produces new knowledge. The EU, China, United States, India, Japan, and South Korea together produce more than 70% of the worldwide refereed S&E publications. As with the worldwide trends for degrees awarded and R&D spending, the output of peer-reviewed S&E publications in recent years has grown more rapidly in middle-income countries, especially China, than in high-income countries, including the United States.
As measured by publication output, the subject-matter emphasis of scientific research varies across countries and regions. Among the largest producers in 2018, the United States and the EU each produced more biomedical and health sciences articles than did China.
However, China surpassed the United States and the EU individually in the production of engineering articles and now produces more than twice as many engineering articles as the United States.
