摘要
文章采用组群分析方法，利用 CGSS2003-2008年调查数据，从微观层面定量分析了中国城镇居民消费支出的人口年龄特征。研究发现，中国城镇居民消费支出的年龄效应和组群效应均呈线性递增趋势，前者的增长率高于后者。消费差距的年龄效应在波动中呈增长趋势，消费差距的组群效应则保持稳定增长。老龄化和组内效应对消费差距变动的贡献明显。最后，从完善社会保障制度、加大教育投资、缓减老龄化等方面提出了建议。
Abstract
Based on CGSS from 2003-2008,this paper applies cohort analysis to quantitatively analyze the expenditure pattern of China’s urban households from the view point of population’s age.The empirical results show that with respect of the change of household expenditure,the age and generational cohort effects are both in a linear increasing trend,while the former is larger than the latter.For consumption inequality,the age effect fluctuates and demonstrates increasing characteristics,while the cohort effect shows a steady rising trend.Moreover,population aging and within cohort effect influence the inequality of consumption significantly.Finally,this article gives some advice from the aspects of perfecting China’s social security system,decreasing education inequality,and slowing down population aging etc.
