| Outline of Final Research Achievements |
This study presents a theoretical model to explain the mechanism of the formation of hierarchical urban systems. Specifically, we develop multi-industrial core-periphery (CP) models with hierarchical (i.e.,multi-scale) spatial structure which introduces the interaction between inter-regional and intra-regional transportation costs explicitly. We then analyze bifurcation phenomena of the equilibrium by the analytical and numerical approaches developed by Akamatsu et al.(2012). The results of our analysis reveal that combinations of inter-regional and intra-regional transport costs can yield a wide variety of agglomeration patterns depending on the transportation parameter values, and that hierarchical industrial location patterns emerge as stable equilibria of the model. Furthermore, we develop multi-scale Computable General Equilibrium (CGE) models with agglomeration economies, and demonstrate their applicability to practical problems.
