摘要缩小城乡居民收入差距是实现共同富裕的基础,基于我国城乡医保制度改革的视角,使用中国劳动力动态调查(CLDS)数据构造多期双重差分模型,评估医保统筹制度对城乡居民收入差距影响的政策效果。研究结果表明:医保统筹政策相对于“新农合”与“城居保”制度显著缩小了城乡居民的收入差距,政策针对农村的低学历、中低收入以及中老年群体产生更明显的效果。机制分析进一步证明统筹医保制度可以通过降低农村居民医疗支出负担、提升其健康水平等渠道缩小城乡居民收入差距。因此,推进医疗保险统筹改革,在制度设计上应该更有针对性地向农村居民群体倾斜,提升受益公平性,为迈向共同富裕提供制度性保障。 Reducing the income gap between urban and rural residents is the foundation for achieving common prosperity.From the perspective of China’s urban-rural medical insurance system reform,this article constructs a multi-period difference-in-differences model using data from the China Labor Force Dynamic Sur‐vey(CLDS)to evaluate the policy effectiveness of the medical insurance integration system on the income gap between urban and rural residents.The research results indicate that the medical insurance integration policy has significantly narrowed the income gap between urban and rural residents compared to the“new rural coop‐erative medical scheme”and“urban residency insurance”systems.The policy has a more significant effect on the low education group,middle and low-income group,and middle-aged and elderly group in rural areas.Mechanism analysis further proves that integrated medical insurance can narrow the income gap between urban and rural residents by reducing the burden of medical expenses on rural residents and improving their health levels.Therefore,we suggest to promote the reform of medical insurance integration policy,more targeted tilt towards rural residents in institutional design,improve fairness in benefits,and provide institutional guarantees for moving towards common prosperity.
