Chinese industrial policy worked, and the evidence is that the cities which pushed hardest on a sector ended up best at both production and patents.

Industrial policy was heavily criticized and again, if I talk to my Harvard professors, they’ll be very, very, very skeptical about the role of the state, especially in such a major way. But if you look at the Chinese experience, the evidence for success is all there. The cities that have pushed the most on supporting that particular sector ultimately did the best in terms of production, but also in terms of innovation, measured by patents. It’s all in the data.
