A dynamic origin-constrained spatial interaction model applied to Poland's inter-provincial migration

In contemporary Europe migratory processes are becoming inceasingly important, given the diminishing impact of natural changes on population dynamics. In this paper, we focus on some determinants of internal migration in Poland. The choice of variables is guided by recent considerations about interregional migration in other transitional economies. The quantitative analysis of Polish migration flows has been performed by considering migration interactions over time. A dynamic version of an origin-constrained spatial interaction model is proposed. This approach relies on using the method of offsets, generalizing the Poisson regression framework, and applied to the calibration of spatial interaction models. © 2010 Regional Studies Association.
