Migration has been seen as an important issue in regional development worldwide. This study analyses the impact of internal migration on provincial growth in Indonesia. Applying a growth model, this study found evidence that migration played no role on regional convergence during the 1975–2005 period. However, different policies affected the signs and sizes of the estimates across sub-periods. Moreover, inter-provincial migration, especially in-migration in poorer provinces, had a positive impact on economic growth in Indonesia.
