摘要

本文研究了加纳农村和城市人口的迁移趋势。矩阵法近似确定了2016 - 2020年加纳农村和城市地区新增人口百分比值。2015年的农村和城市人口值被用作预测其他后续人口值的初始值。图形矩阵和聚类柱状图考察了农村和城市人口的趋势关系。讨论了农村和城市地区人口迁移的新趋势。该方法揭示了城市和农村人口的上升和下降趋势。通过将矩阵法的估计结果与文献中index mundi网站的估计结果进行比较,证明了该方法的准确性。基于这些发现,本文建议加纳政府和其他政策制定者分别采取措施避免城市和农村地区的过度移民流动。

Matrix Dynamics of Migration Trends of Rural-Urban Population in Ghana
This paper studies the migration trends of rural and urban populations in Ghana. The matrix method approximately determines the new population percentage values of rural and urban areas in Ghana from 2016 to 2020. The 2015 rural and urban population values were used as initial values for the projection of the other subsequent population values. The graph matrix and clustered column chart examined the trends relationship between rural and urban populations. The emerging trends of population migration at the rural and urban areas were discussed. The method revealed the upward and downward trends of populations in urban and rural areas. The accuracy of the method is proven by comparing the estimated results from the matrix method with those obtained from the website of index mundi in the literature. On the bases of these findings, the paper recommends the steps to be taken by the government and other policy makers in Ghana to avert excessive migration flow in the urban and rural areas respectively.
