This study aims to probe the determinants of inter-provincial migration flows in Indonesia and how economic and development changes affect migration patterns. We employ three census periods, 1990, 2000, and 2010. Our study finds that an increase in relative inequality between origin and destination provinces decreases inter-provincial migration and relatively high distance elasticity in Indonesia leads to high migration cost. People are more inclined to migrate due to push factors as opposed to pull factors from the destination region, thus indicating a strong relationship between the level of regional development and the willingness of people to migrate.

East Java marine resources play important role as development assets and have  enormous opportunities for generating economic growth. The main potential includes  11 subsectors reinforced by the role of this province as a center of logistics and  connectivity of the Eastern Indonesia Region (KIT). Realizing such potential, both  central and local governments intensively attract investors to invest funds into the  maritime sector in East Java. The study also attempts to deliberate the impact of  investment in the maritime sector on the East Java economy in particular and  Indonesia in general. The impact includes economic growth, society’s welfare, and  employment. This study uses Input-Output Table of East Java Province 2008 published  by the Central Bureau of Statistics (BPS). The data is quantitatively employed to find  the linkage and impact multiplier of the investment. The results of this study indicate  that the investment in the maritime sector induces economic growth of East Java by  11%, which also rises people income and employment rate. With the contribution of  East Java to the national economy, which is about 15%, the investment will also  contribute to boost the national economy.
