When the National Institute of Science and Technology Policy of the Ministry of Education, Culture, Sports, Science and Technology investigated the situation of R & D expenses in 2019 in each country in the world, Japan was the third largest in the world as in the previous year, but the difference between the top US and the second largest China was further increased. It turned out to be widespread. The number of notable papers in the natural sciences from 3 to 2 dropped by one to 2017th, the lowest ever, highlighting the decline in the international status of Japanese research activities.
According to the Ministry of Education, Japan's R & D expenses were 18 trillion yen, 0.2% higher than the previous year and ranked third after the United States and China as in the previous year.However, the United States is growing at 3% and China at 8.2%, which is much faster than Japan, and the difference is even wider.
The number of researchers was 68.2, which was the third highest after China and the United States.However, the number of researchers at universities has decreased by 3% compared to five years ago, showing the weakening of Japan's research system.
The number of notable papers in the natural sciences, which are often cited in other papers, is 2017 per year from 2019 to 1.The world ranking is 3787th after China, the United States, the United Kingdom, etc., and it has been overtaken by India from 10th place last time (2016-2018), dropping one rank. Ten years ago, from 9 to 1, he was in 10th place, so he seems to be declining.
The total number of papers is also 4th, down from 10rd place 3 years ago.While the number of papers in each country is increasing, Japan has only increased slightly 10 years ago.
