非农户籍转换如何影响农民工消费差距——来自CMDS的经验证据

How Conversion of Non-agricultural Household Registration Affects Consumption Gap of Migrant Workers:Empirical Evidence from CMDS

深化户籍制度改革是推动农业转移人口市民化,扎实推进共同富裕的重要举措。基于中国流动人口动态监测调查(CMDS)数据,考察非农户籍转换对农民工消费差距的影响及作用机制。研究发现,转换为非农户籍可以有效降低农民工之间的消费差距,且该影响效应在低收入、低社会网络与低心理融入水平的群体中更明显。工具变量分位数回归结果显示,在低分位点上,非农户籍转换对农民工消费差距的缓解效应并不明显,但随着分位点的上升,非农户籍转换的影响程度逐渐提高,呈显著的线性上升趋势。进一步研究表明,非农户籍转换通过就业机会效应、福利可及效应与社会资本效应对缩小农民工消费差距产生间接作用。研究结论为把握中国户籍制度改革的福利效果增添了新的经验证据,为助推农民工市民化质量和促进共同富裕提供了重要启示。

Deepening household registration system reform is an important measure to promote urbanization of agricultural transfer population and solidly promote common prosperity.Based on the data of China Migrant Population Dynamic Monitoring Survey(CMDS),this paper examines the impact and mechanism of the conversion of non-agricultural household registration on the consumption gap of migrant workers.The study has found that switching to non-agricultural household registration can effectively reduce the consumption gap between migrant workers,and it is more obvious in groups with low income,low social network and low level of psychological integration.The instrumental variable quantile regression shows that the conversion of non-agricultural household registration is not very obvious in alleviating the consumption gap between migrant workers at the low quantile,but as the quantile increases,the impact of non-agricultural household registration conversion gradually increases,showing a significant linear upward trend.Further research shows that the conversion of non-agricultural household registration has indirect effects on narrowing the consumption gap of migrant workers through the employment opportunity effect,welfare accessibility effect and social capital effect.The paper provides new empirical evidence for a comprehensive grasp of the welfare effects of China’s household registration system reform,and provide important enlightenment for boosting the quality of migrant workers’urbanization and promoting common prosperity.
