This paper adopts the push and pull model of migration to explain inter-provincial migration flows across
63 provinces or cities of Vietnam in the period 2004-2009. We used a solution to a quadratic cost
migration problem by combining the total number of in and out-migration of various provinces and inverse
distances between provinces that aims at calculating the push and pull factors of each province. The
result confirms the hypothesis that push factors correlate well with total out flows of provinces and pull
factors with total inflows of provinces. In addition, it is found that pull and push factors are explained
rather well by population size and income, but not so by urbanization and poverty.
