Dear colleagues, 
Since the NSF has held a workshop on November 7 on "the decline of US
science," I was asked whether this "decline" can be explained in terms of
the increases of China. Indeed, it can! The figure below shows that the US
looses 0.23% point/year and the EU-25 0.34%, while China gains 0.71%/year
when using linear fits. Consequently, the decline of the (US + EU) does not
even fully account for the gains of China; the rest of the world also
contributes 0.14%. In other words, it seems that the shifts are
approximately pro rato.
These figures are based on: Loet Leydesdorff & Caroline Wagner,
