东京一极集中与促进向地方迁居

This study analyzes interregional migration decision-making in terms of utility maximization. Given that indirect utility consists of real income and migration costs, migration decisions depend on whether additional benefits of real income by migration at least offset the costs of migration. To quantify migration costs from interregional migration flow data, this study constructs a structural model of migration decision by incorporating different migration costs based on different age ranges. This study further discusses whether current migration policy is effective based on the counterfactual results since the Japanese government currently promotes urban-to-rural migration policy measures for regional revitalization in order to correct monopolar concentration in Tokyo.
