The main findings confirm that labour mobility has an important role in narrowing the rural-urban income gap, not only in theory but also in practice. Although the empirical efforts are still preliminary and are not sufficient to prove this conclusion, they lay out a new direction for further research on the subject. Moreover, as more people have shifted from unemployment and underemployment to full employment through mobility between regions and sectors, mainly benefiting rural workers and their families, the income gap between rural and urban areas has tended to narrow. Since the rural-urban gap contributes the major part of overall inequality, the narrowed gap will in turn reduce the country’s overall income inequality.
