I'd like to point out that a lot of "defense" research ends up used primarily or even exclusively for things other than military applications. The military is used as a feeder for R&D because calling it defense is how you sell useful spending (and Keynesian stimulus) to conservatives. The US defense budget is full of only nominally defense R&D. This is probably as true in China as it is in the USA.

The US did this quite a bit, especially during the height of the Cold War. In fact you go could so far as to say that America's elite schools operate (or did at least then) as intellectual feeders for the defense industry.
