Abstract
The impact of sea level rise due to global warming on developing countries facing sea is a great concern. To investigate the impacts of sea level rise on socio-economy by, the theoretical frame for the developing economy should be clarified. The Harris-Todaro's two sector (ruralurban) model which considers unemployment and migration can be the basis for it. This paper proposes a macroeconomic model for analyzing not only the structural changes in industrial sectors including manufacture, forestry, and also the migration.
