the yearly change of average value of each indicator. (1) The total number of
Patents is increased from 8426 in 2006 to 22,224 in 2010. (2) The total numbers of
SCI articles and EI articles are 41,808 and 44,647 respectively in 2006, and then
increased to 66,388 and 68,906 respectively in 2010. (3) The total number of
TOPESI articles increases during thefive-year period, from 387 in 2006 to 710 in
2010, with the largest increment of 236 articles appearing in 2010. In Appendix, we
also make a list containing the universities which published more than 10 TOPESI
articles every year. According to the Appendix, Peking University and Tsinghua
University are the top two on the list, and the 985Us’share of TOPESI publications
is more than 77% every year. (4) The total number of CSCD articles decreases
during thefive-year period, and the total number of Monographs isfluctuant to
some extent but doesn’t change too much.
Concerning the coefficient of variation, among all the output indicators, the
coefficient of variation TOPESI is the largest, reflecting that there is a big gap
between 211Us in publishing on international top journals. Contrarily, the coeffi-
cient of variation of CSCD indicator is the smallest, showing a much equalized
situation of publishing on Chinese journals. From the view of time trend, the
coefficient of variation of every output indicator is decreasing by year.
We can observe the research output change of each NEAM research output
indicator by calculating the yearly change rate of each NEAM research output in
211Us. See Table3.16for details.
It can be seen from Table3.16, the numbers of Patents, SCI articles and EI
articles are on a steadily rising trend, while the yearly change rates of CSCD
articles, TOPESI, and Monographs are positive in certain years and negative in
some other years.
In order to illustrate more visually the trend of NEAM research outputs in
211Us, we plot each indicator in line chart. Please see Figs.3.29,3.30and3.31.
It can be seen from Fig.3.29, the average of Patents is on a steadily rising trend
across the period of 2006–2010. Referring to Table3.1, the average of Patents is
84.26 in 2006 and then increased to 222.24 in 2010.
It can be seen from Fig.3.30that, the averages of SCI and EI articles are on a
slowly rising trend with almost the same pace. The average of SCI articles is
increased from 418.08 in 2006 to 663.88 in 2010, and that of EI articles is increased
from 446.47 in 2006 to 689.06 in 2010. By contrast, the average of CSCD articles
first increases then decreases, but the overall change is not so obvious. In 2006, the
average of CSCD articles is 1354.73, and then grows steadily from 2007 to 2009,
but decreased to 1397.54 in 2010.
It can be seen from Fig.3.31, the average of TOPESI articles is on a rising trend,
from 3.87 in 2006 to 7.1 to 2010, and the increment in 2010 is the largest. The
average of Monographsfirst decreases then increases, going from 11.67 in 2006
down to 9.83 in 2007, and then up to 12.06 in 2010.
