China's trade pattern is influenced not just by its overall comparative advantage in labor intensive goods but also by geography. We use two variants of the Eaton-Kortum (2002) model to study China's local comparative advantage. The theory predicts that China's share of export markets should grow most rapidly where China's share is initially large. A corollary is that exporters that have a big market share where China's share is initially large should see the largest fall in their market shares. These market share change predictions are strongly supported in the data from 1996 to 2006. We also show theoretically that since trade costs are proportional to weight rather than value, relative distance affects local comparative advantage as well as the overall volume of trade. The model predict...
