SUBJ: China Science and Technology Assessment Report


A report on the structure and infrastructure of Chinese science and
technology (1) is now available for downloading
Highlights of the report include:



*       China's output of research articles has expanded dramatically in
the last decade (articles published in the Science Citation Index) 
*       China is among the research output leaders, especially in
critical technologies (e.g., nanotechnology, energetic materials) 
*       China's major research collaborators are, in order: USA, Japan,
Germany, England, Canada, Australia 
*       China-USA collaboration emphasizes biomedical first and
nanotechnology second, whereas China-Japan collaboration reverses this
*       There are critical research and technology sub-areas where China
leads the USA in absolute numbers of research articles published.  In
these areas, China has at least four times the relative investment
emphasis as the USA, since total USA articles are four times the number
of total China articles. 
*       Relative to the USA, China emphasizes the hard sciences that
underpin defense and commercial needs 
*       Relative to China, the USA emphasizes medical, psychological,
and social problem research areas 
*       China's research articles can be assigned to four major
categories: Physics/ Materials (13966 records); Life Sciences (7377);
Mathematics (7162); Chemistry (5841) 





*       Chinese researchers publish in many Chinese journals, but cite
very few Chinese journals 
*       Chinese researchers publish in low Impact Factor journals, but
cite relatively high Impact Factor journals (Impact Factor measures a
journal's ability to attract citations) 
*       Chinese researchers publish in much lower Impact Factor journals
than do USA researchers 
*       China-USA collaboration doubles citation impact of Chinese
*       China's research impact was larger than India's in all major
research categories (Physical/ Environmental/ Materials/ Life Sciences,
as measured by median of top ten cited articles in each sub-area, for
technical sub-areas of similar research output) 
*       China's research impact was smaller than Australia's in all
major research categories 
*       Global nanotechnology researchers cite only a handful of Chinese
journals with significant numbers, and even these journals have two
orders of magnitude less citations than the leading international


As the above and other studies have shown, aggregate country publication
productivity and citation impact results can be somewhat misleading.
Publications and citation impact in critical technologies and
sub-technologies are most important, and should serve as the basis for
publication and citation comparison.
