HAMAGUCHI Nobuaki (Program Director and Faculty Fellow)



We analyze three main topics of the regional economies of Japan where the population is predicted to continue to decline for at least the next 100 years. These topics are the revision of regional spatial structure which has strengthened the Tokyo-monocentric concentration; enhancing the resilience of destabilized de-popularizing regions; and internationalization of regional firms. This project is an extension of and new developments based on the results obtained from our previous projects in RIETI's Regional Economies program. The topic of the revision of regional spatial structure is related to the study on the regional spatial structure compatible with the positive effects of skilled labor turnovers across regions on innovation outcomes. In relation to this topic, we study human capital development required especially in large cities for computerized working environments with the introduction of artificial intelligence. The resilience of regional economies focuses on the condition for the introduction of a business continuity plan (BCP) in small and medium-sized firms, with particular attention to the business relationship with regional financial institutions. The study on the internationalization of regional economies analyzes the Kyushu region on topics such as networking through supply chains and retail sellers and business with Asian countries.
