Although the number of papers published by domestic universities from 2013 to 2015 is increasing in the fields of environment / earth science and clinical medicine, it is rapidly decreasing in the fields of chemistry, materials science, and physics. It was found in a survey by the National Institute of Science and Technology.
科学技術・学術政策研究所は国内の大学を論文数シェアが4.5％以上の第1グループ（大阪、京都、東京、東北大学）、1％以上の第2グループ（岡山、早稲田大学など13校）、0.5～1％の第3グループ（信州、大阪市立大学など27校）、0.05～0.5％の第4グループ（北九州市立、麻布大学など140校）に分け、2013～2015年と2003～2005年の論文数を比べた。
According to the report, chemistry showed a decrease of 4 to 6% in 15 groups, and a decrease of 12% in the whole country.Materials science is down 8-26%, down 23% for the whole country.Physics showed a 21-25% decline, a 27% decline across the country.
In engineering, the 1st group decreased by only 1% and the 2nd group increased by 8%, but the 3rd group decreased by 5% and the 4th group decreased by 9%, minus 9% in the whole country.Basic life sciences showed a decrease of 2-10%, a decrease of 4% in the whole country.There are calls for a decline in Japan's research capabilities, but the reality is once again highlighted.
On the other hand, in environmental and earth sciences, where the number of papers has increased significantly, each group has increased the number of papers by 20 to 48%, and the number of papers has increased by 22% in Japan as a whole.The clinical medicine field has also grown by 10 to 22%, increasing by 19% in Japan as a whole.
