Public sector spending on ag research declining in the West
Chinese government spending on agricultural R&D rose nearly eightfold in real (inflation-adjusted) terms between 1990 and 2013, surpassing U.S. spending in 2008 and more than doubling it in 2013.
In simple dollar terms, the decline in U.S. public sector funding has been more than offset by a rise in U.S. private research spending, but the two are not substitutes, as each tends to specialize in different kinds of R&D.
