Interregional Gross Migration and Structural Changes in Local Industries

In this paper the impacts of structural changes in local industries on interregional gross migration in Japan for 1974–85 are empirically examined. Structural changes in local industries, which are represented by a simple index of local employment growth dispersion across sectors, induce interregional migration, as well as intraregional migration. The estimation results with pooled data support this hypothesis. The impacts of structural changes in local industries are different across gross migration flows (rural—urban, urban—rural, urban—urban, and rural—rural migration), as are the impacts of other determinants of migration such as earnings differentials, aggregate employment growth, national unemployment, distance, and age structure.
