本研究考察了政治、经济和人口因素对流向北美的移民规模和构成的影响。一个修正的重力模型被指定和调整，以包括移民法规和具体到原籍国和目的地国的特点。为了对模型进行实证检验，研究的时间段为1976-1986年，涵盖70个国家，总共有1540次对加拿大和美国移民流动的观测。结果表明，原籍国的人口和目的国的收入是移民到北美的两个主要决定因素。亚洲和拉丁美洲的人口密集地区提供了很大一部分移民。研究发现，原籍国国内对政治和公民自由的限制严重阻碍了向北美的移民。
This study examines the influence of political, economic and demographic factors on the size and composition of migration flows to North America. A modified gravity model is specified and adjusted to include immigration regulations and characteristics specific to the origin and destination countries. For empirical test of the model, the time period of study is from 1976-1986, and 70 countries are covered for a total of 1540 observations of migration flows to Canada and the USA. The results reveal that the population of origin countries and the income of destination countries are two major determinants of migration to North America. High population areas of Asia and Latin America provided a large share of the immigrants. Domestic restrictions on political and civil freedom in origin countries are found to significantly impair migration to North America.
