> So what is the economic fitness? It is, in short, a measure of the complexity of a country’s exports. The idea is that exports represent the products from a country that are competitive with like products from the rest of the world. The larger the variety of exported products, the fitter an economy is. This is a different approach, I guess, because, more typically, an economist might assess an economy's strength by simply tallying up the total value of its exports in dollars -- or perhaps even by placing rather little weight on the export picture at all, focusing instead upon other aspects?
