GDP增长率和人口

GDP growth rate and population

Ivan O. Kitov

摘要:

发达国家的实际GDP增长率是两项之和。第一项是有工作经验的平均收入增长期Tcr的倒数。美国目前的Tcr值为40年。第二项与人口有内在联系,由特定年龄(在美国为9岁)的人数的相对变化定义,(1/2)* dN 9(t)/N9(t),其中N9(t)是时间t时9岁儿童的人数。Tcr的增长是人均实际GDP的平方根。因此,实际国内生产总值的演变仅由一个参数定义-特定年龄的人口数量。美国,英国和法国的预测和讨论。人均实际国内生产总值也有类似的关系。人均GDP年增量也是经济趋势项和同一特定年龄人口项的组合。过去55年的经济趋势项等于400美元(2002年美元)除以人均实际国内生产总值。因此,经济趋势项的渐近值为零。对国内生产总值的测量值进行反演,以恢复1955年至2003年特定年龄人口的相应变化。以GDP为基础的人口恢复方法可能比常规人口普查具有更高的准确性。

英文摘要:

Real GDP growth rate in developed countries is found to be a sum of two terms. The first term is the reciprocal value of the duration of the period of mean income growth with work experience, Tcr. The current value of Tcr in the USA is 40 years. The second term is inherently related to population and defined by the relative change in the number of people with a specific age (9 years in the USA), (1/2)*dN9(t) /N9(t), where N9(t) is the number of 9-year-olds at time t. The Tcr grows as the square root of real GDP per capita. Hence, evolution of real GDP is defined by only one parameter - the number of people of the specific age. Predictions for the USA, the UK, and France are presented and discussed. A similar relationship is derived for real GDP per capita. Annual increment of GDP per capita is also a combination of economic trend term and the same specific age population term. The economic trend term during last 55 years is equal to $400 (2002 US dollars) divided by the attained level of real GDP per capita. Thus, the economic trend term has an asymptotic value of zero. Inversion of the measured GDP values is used to recover the corresponding change of the specific age population between 1955 and 2003. The population recovery method based on GDP potentially is of a higher accuracy than routine censuses.
