摘　　要：本文以家庭劳动力供给为研究视角,在双薪生命周期模型的框架下,利用CFPS的数据识别出家庭劳动力供给自身消费平滑的效应。研究结果表明,对于妻子的工资收入冲击,家庭劳动力供给带来的消费平滑效应更加突出,而对于丈夫的工资收入冲击,往往需要借助家庭资产积累等渠道多管齐下,才能进行更为有效的消费保险平滑。针对不同年龄组而言,30～47岁这个年龄段的夫妻具备更强的劳动力供给自身消费平滑的效应,财富的平滑效应对处于48～60岁之间中老年夫妻的家庭更为突出,而20～29岁的年轻夫妻是国内消费大军中的"弱势群体"。此外,我们还发现税收冲击对不同类型家庭劳动力供给消费平滑能力的影响存在明显的异质性。高收入群体没有显著提高自身消费倾向,而低收入群体也没有受到所得税改革再分配效应的刺激,只能更多地依靠金融市场与亲友借贷去维持消费平滑。With the supply of family labor as a research perspective,this paper uses CFPS data to identify their own smooth consumption effect of labor in the framework of double salary life cycle model.The results show that,for the wife’s wage income impact,the smooth consumption effect is more prominent from labor supply,and for her husband’s wage income shocks,the other consumption smoothing channels are in need.In the case of different age groups,couples who are in the ages of 30-47 years have stronger effect of labor supply to their own smooth consumption,and the smoothing effect of wealth is more prominent among families between 48 and 60 years old.20-29 years old young couples are in the“vulnerable groups”of consumption.In addition,we also found that high-income groups,although are affected by the tax reform,but did not significantly improve their own propensity to consume,and low-income groups have not been affected by the re-allocation of tax incentives who can only rely more on financial markets and friends and relatives to maintain consumption smoothing.
