中国省级人口分布影响因素的定量分析*

本文主要用1987年的数据,对影响省级人口密度的31种因素指标进口了相关和回归分析,建立了各种因素对人口密度的回归公式。作者引进了两个新的经济指标:单位国土面积粮食产量和国民收入。分析表明这两个指标比其他经济指标与人口密度的相关更紧密,自然因素尤其是海拔影响最大,其次是经济因素。

THE QUANTITATIVE ANALYSIS OF FACTORS INFLUENCING POPULATION DISTRIBUTION IN CHINA

The correlation between provincial population density and its 31 influencing factors are analysed. Here two new economic indexes are introduced, grain yield per unit territory area and national income per unit territorory' area. The results of analysis show that these two indexes have closer relationship with population density than other economic indices, within all the 31 indices analysed,natural factors, especially elevation above sea level, influence population density most prominently. Economic factors influence population density more prominentely than population factors do. Educational factors have the weakest effect on population density.
