The world share of science and social-science papers for the People's Republic of China over a recent five-year period, expressed as a percentage of papers in each of 22 fields in the Thomson Scientific database. Also, China's relative citation impact compared to the world average in each field, in percentage terms.View the 10-year country rankings for China, 1995-June 30, 2005. Field Percentage of papers from China and Relative impact compared to world Materials Science 11.56 -22 Physics 9.15 -36 Mathematics 8.95 -16 Chemistry 8.29 -36 Engineering 6.89 -23 Geosciences 5.76 -34 Computer Science 5.48 -25 **<--- China's overall percent share, all fields: 4.66 --->** Space Science 4.04 -51 Ecology/Environmental 3.84 -40 Pharmacology 3.71 -51 Economics & Business 2.66 -10 Plant & Animal Sciences 2.40 -28 Biology & Biochemistry 2.30 -54 Agricultural Sciences 2.16 -17 Microbiology 2.12 -43 Education 1.97 -48 Molecular Biology 1.84 -47 Clinical Medicine 1.70 -24 Social Sciences 1.40 -22 Neurosciences 1.35 -44 Psychology/Psychiatry 1.07 -30 Immunology 1.06 -59 Between 2000 and 2004, Thomson Scientific indexed 175,522 papers that each listed at least one author address in the People's Republic of China. Of those papers, the highest percentage appeared in journals classified under the heading of materials science, followed by physics and mathematics. As the right-hand column shows, the citations-per-paper score for materials-sciences papers from researchers in China was 22% below the world average in the field (1.80 citations per paper for China, versus a world average of 2.30 citations per paper). Although the citation impact of papers from researchers based in China has not yet reached the world average in any of the fields shown, the country made comparatively strong showings in mathematics (just 16% below the world average), economics & business (10% below), and agricultural sciences (-17%). 10-Year Country Rankings (all fields) for:China Total for China Papers Citations Cites Per Paper 324,483 1,088,453 3.35 Rank for China among the 146 top performing countries: #14 #8 #123 [ Last edited by sdlwwxb on 2005-12-16 at 18:21 ] |
