I'm not sure the Y axis in either chart gives any truly meaningful implication. The first one gives USD$ millions spent and the second gives just the number of publications. Lets look at the first one. Lots of article state that the efficiency of capital use (ie: how much return you get for putting in $1) in China is much lower than that in the US. Googling even shows that China's capital efficiency, because of the lack of transparency and a command-control government-economy, is even lower than competitive developing countries like Vietnam, India and Thailand.
