|Outline of Final Research Achievements
We have two main theoretical achievements. One concerns the agglomeration in a regional economy. We generalized the existing two-region models to a many-region setup and showed that they reduce to two prototypes regarding the equilibrium bifurcation behavior. The other concerns the agglomeration within a region, typically the business district formation within a city. We developed a potential game-theoretic approach to the formal solution for the models in this literature.
On the empirical side, we showed in six major countries that the size-location pattern of cities exhibits spatial fractal structure associated with common power law for city sizes in each fractal part. We further showed evidence that this regularity accrues from the spatial coordination of many industries differing in increasing returns. We are in the process of replicating this empirical regularity from a many-region and many-industry extension of our theoretical model above.
