摘要
中国进入快速的人口老龄化阶段,对于老龄化与经济增长关系如何认识,是值得不断研究的课题。采用面板分位数和面板非参数模型实证检验了老年人口比重对省际经济增长的影响,研究发现:老年人口比重与经济增长之间存在倒U型关系,不同分位数条件下,老年人口比重对经济增长影响的转折点有所不同。总体上,老年人口比重对省际经济增长率具有正向影响,但是效应是逐渐递减的,当超过转折点之后,其效应由显著正向影响变为不显著负向影响。面板非参数估计表明,老年人口比重对经济增长的影响随经济发展水平程度的提高而逐渐减弱,并向负向效应转变,但是当经济发展水平达到一定程度之后,老年人口比重的提高转而对经济增长具有正向效应。
This paper investigates the effect of old age population ratio ( the percentage of the number of persons 65 years and over of total population) on provincial economic growth. We find there is inverse "U"-shaped relationship between old age population ratio and economic growth. Under different quantiles the turning point is different. In total, old age population ratio has positive effects on economic growth, but the effects become small when the economy entity enters into old age entity. When the ratio increases over the turning point the effect becomes negative. The estimation result of nonparametric panel data model indicates that the effect of old age population ratio on economic growth decreases and turns to be negative with the growth of per capital GDP, but when per capital GDP increases to some degree the effect becomes positive again.
