摘要：

在不断完善对时期生育率的测量指标中,人口学家们提出了各种基于对生育行为各个方面进行控制的生育率指标,以便获得更为准确的生育水平度量。对生育率的数量成分和进度成分的分解,使得我们对时期生育率的变化有了更深入的认识。针对递进生育率和去进度效应总和生育率的缺陷,澳大利亚学者提出了内在总和生育率的指标,并通过实证研究表明它能更准确测量生育率的数量效应和进度效应。内在总和生育率是对生育的年龄、胎次和间隔同时进行控制的生育率指标,反映的是生育行为内在稳定的生育水平。本文对这一方法进行介绍,并利用我国1988年2‰人口生育率抽样调查数据,说明该指标的构建和计算过程。

Demographers have attempted to refine period fertility rates in order to accurately measure fertility levels. A better understanding of changes in period fertility rates is achieved by decomposing total fertility rate into quantum and tempo components. A recently developed approach to addressing the defects of tempo-adjusted total fertility rate,the intrinsic total fertility rate, simultaneously standardizes total fertility rate by age,parity and birth intervals;and empirical studies have shown that it can more accurately measure the quantum and tempo of fertility. This paper introduces the intrinsic total fertility rate,elaborating on its construction and calculation using China's 1988 fertility survey data.
