Coupling Relationship between Population and Economy in Africa
In the regional study, one of the significant topics is the change in distribution of population and economy. By using the methods of regional gravity center, coupling index and geographic concentration index, with the population and GDP data in Africa in2003-2012, the coupling characteristics of the population and the economy of Africa are elaborated in this paper. The conclusions are as follows: 1) The degree of geographic concentration of population was higher in eastern and western Africa, in comparison with that in central Africa; 2) The degree of geographic concentration of economy was lower in central Africa than that of thesurrounding regions; 3) There existed a moderate positive correlation between thedegree of geographic concentration of population and that of economy. 4) According to coupling index, Africa can be divided into five types: economic polarization, economy ahead of population, coordinate development, economy lagging behind population, and economy lagging far behind population. 5) The gravity centers of population and economy were both located in the southeast direction of the geometric gravity center of Africa. During 2003-2009, at the macro-trend, the coupling relationship of gravity center between population and economy was obvious;during2010-2012, the extending tracks of gravity center of population and that of economy were different because of economic crisis and political insurrection.
