泰勒幂法则对中国人口死亡率的检验

Taylor's Law Tests on China's Population Mortality

Taylor幂法则可揭示物种种群大小、密度方差与均值的规律特征.本文将Taylor幂法则引入人口学,利用其分析了全国及31个省(市)各年龄死亡率的规律特征.得出结论:全国及31个省(市)各年龄死亡率的方差与均值在对数尺度上存在着线性关系,各省(市)的线性强弱有所差异,但是差异不大,且基本无性别差异.

Taylor＇ s law can reveal the regularity of variance and mean of population size and densi-ty. In this paper, Taylor＇ s law is introduced into the demography, and it is used to analyze the reg-ular characteristics of the mortality rate of China and 31 provinces （cities）. It is concluded that there is a linear relationship between the variance and the mean of the age death rate of the 31 prov-inces （cities） , and the linearity of each province （city） is different, but the difference is not gender differences.
