Has China begun its “Science and
Technology Takeoff”?
• Most large OECD nations experienced S&T takeoff
in which R&D/GDP rose rapidly from < 1% to > 2%.
• R&D/GDP has risen from 0.06% in 1996 to 1.3% in
2003.
• This is a measure only of R&D intensity, not quality

What factors motivate firms to spend more on R&D, i.e.
increase the ratio of R&D labor to the total workforce?
1. The demand for technology intensive intermediate
inputs
rises in relation to that of production labor,
2. The productivity of R&D labor rises,
3. The ability to convert the existing stock of knowledge
grow
into new innovations grows,
4. Subsidies to R&D labor increase.

Conclusions and discussion
Other factors affecting the timing of China’s S&T takeoff:
 Size – market size motivates investors to locate (achieve
scale economies) in China rather than depend on imports.
 Geographic location (e.g. proximity to Japan, S. Korea,
H.K., and Taiwan
 Domestic S&T policy, e.g. technology for markets
