"In this paper the determinants of internal migration in Kenya are analyzed on the basis of a human capital model. Explanatory variables included in the specification are both economic (wage rates and employment rates) and noneconomic (for example, population density and educational attainment). Also incorporated are variables which reflect intervening opportunities.... The econometric results show that destination variables are important determinants of internal migration, as is distance between the districts. Further, the variables for the intervening opportunities add significantly to the explanatory power of the model."
本文基于人力资本模型对肯尼亚国内移民的决定因素进行了分析。模型设定中包含的解释变量既有经济变量（工资率和就业率），也有非经济变量（例如人口密度和受教育程度）。还纳入了反映中介机会的变量……计量经济学结果表明，目的地变量以及各地区之间的距离是国内移民的重要决定因素。此外，中介机会变量显著增强了模型的解释力。
