(8) Accessibility Improvement and Migration in the Age of Declining Population: From the Mew of Spatial Economics

摘要

This paper investigated the effects of accessibility improvement, agglomeration economies and political expenditures on the promotion of migration with using the data of 2005/06 and 2015/16 in Japan. Before estimating the reduced form specification derived from Spatial Economics, we sorted the migration as two types. The first type is the migration from declining population prefectures. The second type is the migration from increasing population prefectures. As the results of estimations from first type, it was revealed that service industry's scale economies and market potential based on manufacturing industry have significant positive effects on the migration from declining population prefectures, and the transportation cost and time, and political expenditure have significant negative effects on it. As the results of estimations from second type, it was revealed that service industry's scale economies have significant positive effects on the migration from increasing population prefectures, and the transportation cost and time have significant negative effects on it. However, in this direction of migration, we could not find the effects of market potential based on manufacturing industry.
