Loet Leydesdorff & Ping Zhou


Institutions and their aggregates are not the right units of analysis for
developing a science policy with cognitive goals in view. Institutions,
however, can be compared in terms of their performance with reference to
their previous stages. King's (2004) 'The scientific impact of nations' has
provided the data for this comparison. Evaluation of the data from this
perspective along the time axis leads to completely different and hitherto
overlooked conclusions: a new dynamic can be revealed which points to a
group of emerging nations. These nations do not increase their contributions
marginally, but their national science systems grow endogenously. In
addition to publications, their citation rates keep pace with the
exponential growth patterns, albeit with a delay. The center of gravity of
the world system of science may be changing accordingly.
