Important point.
Been banging on about this in the European debate.
The distinction a lot of economists draw, advocating Europe should go for high-tech and abandon others sectors doesn’t do justice to clustering.
Truism but unfortunately it really is more complicated.
This is a brilliant chart of China's tech-industrial ecosystems, by Kyle Chan.
Most of us economists don't understand that clusters of technological capabilities cut across our categories of 'sectors' and 'industries'.
This chart gets that across in a fantastic way.
