摘要
生命周期理论认为人口年龄结构会影响储蓄投资行为,储蓄投资和经常账户的人口结构效应表现为与抚养负担的反向关系,但实证文献却并没有达成统一意见。文章尝试建立动态面板和静态面板模型,运用系统广义矩(GMM)、混合最小二乘(PooledOLS)、固定效应(FE)、似无相关回归(SUR)等方法对亚太经合组织(APEC)20个国家或地区1993-2010年的面板数据进行了分析。分析发现,经常账户的人口结构效应表现稳健,呈显著负向关系,但储蓄和投资行为的人口结构效应对于样本和方法比较敏感。具体到人口结构内部,老年抚养比效应表现稳健,反向系数在0.26至0.33之间,少年抚养比效应则较为模糊或微弱。
According to life-cycle theory, demographic age structure can affect savings and investment behavior. The effects of demographic structure on savings, investment and current account balance are featured by negative relationships with dependency ratios, but empirical literature has not reached a consensus. This paper tries to construct dynamic and static panel models and employs GMM, pooled OLS, fixed effects and SUR to analyze the panel data of 20 APEC members from 1993 to 2010. It comes to the con- clusion that current account balance is significantly negatively related to de- mographic structure, which is robust, but the effects of demographic struc- ture on savings and investment behavior are sensitive to the sample and methods. For internal demographic structure, the effect of elderly depend- ency ratio is robust with reverse coefficient from 0. 26 to 0. 33, and the effect of youth dependency ration is comparatively vague or weak.
