What drags and drives mobility? Explaining Canada's aggregate migration patterns
利用重力模型和加拿大1991-2006年人口普查数据，研究了劳动力市场差异和省级边界等因素对国内人口迁移的影响，发现劳动力市场差异促进迁移，而省级边界对低人口地区迁移影响最大。
Abstract Understanding the factors that determine the migration of labour between regions is crucial for assessing the response of the economy to macroeconomic shocks and identifying policies that will encourage an efficient reallocation of labour. Using a gravity model, Poisson pseudo‐maximum likelihood specifications and Census data for 69 economic regions, this article examines the determinants of aggregate migration within Canada from 1991 to 2006. Our results suggest that migration tends to increase with differences in labour market performance. We also find that provincial borders have the strongest impact on migration involving low‐populated regions and that distance is most important across provincial borders.
