摘要
基于均值分解方法和分位数分解方法,利用2017年全国流动人口动态监测调查数据分析了新生代流动人口与第一代流动人口的消费差异来源。均值分解结果表明,两代流动人口的消费差异既受到流动人口的个体特征影响,又受到消费理念的影响,其中,对消费差异影响最大的变量是收入。新生代流动人口的消费弹性大于第一代流动人口,说明新生代流动人口的消费对于收入变动的反应更为敏感。分位数回归结果表明,在两代流动人口中,高消费群体的消费弹性更高,消费对收入的变动更敏感。在各分位点上,新生代流动人口的消费弹性均大于第一代流动人口,表明新生代有更大的消费潜力。两代流动人口的消费差距随着分位点的上升而扩大,在各分位点上,特征差异对消费差异的贡献率大于系数差异的贡献率。据此结论,提出了政府应提升流动人口的个人禀赋条件、增强流动人口的融入能力、加快流动人口的市民化等政策建议。
Based on the mean decomposition method and quantile decomposition method,the sources of consumption difference between the new generation and the first generation of floating population are analyzed by using the data from the dynamic monitoring survey of national floating population in 2017.The results of mean decomposition show that the consumption difference between the two generations of floating population is affected by both the individual characteristics of the floating population and their consumption concept,of which income is the variable that has the greatest impact on consumption difference.The consumption elasticity of the new generation of floating population is greater than that of the first generation,which indicates that the consumption of the new generation of floating population is more sensitive to the change of income.Quantile regression results show that in the two generations of floating population,the consumption elasticity of high consumption group is higher,and its consumption is more sensitive to the change of income.At each quantile,the consumption elasticity of the new generation of floating population is greater than that of the first generation,indicating that the new generation has greater consumption potential.The consumption gap between the two generations of floating population expands with the quantile increasing,and at each quantile the contribution rate of characteristic difference to consumption difference is greater than that of coefficient difference.Based on this conclusion,the policy suggestions are put forward that the government should promote the personal endowment conditions of the floating population,enhance their integration ability,and speed up the citizenization of the floating population.
