Rice production is crucial for food security in China, and its relationship with rural labor migration has been studied extensively. Labor migration in rural China has taken new forms in recent years. There has been a discernible trend wherein adult children have started migrating to cities while their elderly parents return to villages to re-engage in on-farm work. The phenomenon has notably shaped the intergenerational division of labor (IDL) within households. However, it remains to be seen how farmers adjust their rice production systems in response to the IDL. The age of 60 years for employment injury insurance is the eligibility threshold for off-farm employment and is used to obtain a source of exogenous variation in the IDL. Based on a representative household survey of 1,752 rice farmers in the Hubei Province of Central China, our fuzzy regression discontinuity analysis reveals that farmers in IDL households are more likely to adopt ratoon rice (RR) than single cropping rice (SR) or double cropping rice (DR). The effect of the IDL varies under different levels of operational scales and specialized agricultural service availability. Further analysis suggests that farmers’ arrangements are associated with two potential mechanisms of downward intergenerational transfer. Monetary transfer for urban housing purchases increases RR in IDL households, and time transfer for intergenerational childcare significantly promotes SR in IDL households. This study enhances the understanding of the relationship between rural labor migration and rice production in China, providing a reference for adjusting rice production systems to ensure food security.

水稻生产对中国的粮食安全至关重要，而水稻生产与农村劳动力迁移之间的关系已得到广泛研究。近年来，中国农村劳动力迁移出现了新的形式。一个明显的趋势是，成年子女开始进城务工，而年迈的父母则返回农村重新务农。这一现象显著地改变了家庭中的代际分工（IDL）。然而，农民如何根据代际分工调整其水稻生产系统仍有待观察。工伤保险的 60 周岁年龄是非农就业的资格门槛，它被用来获得 IDL 的外生变化来源。基于对中国中部湖北省 1,752 户水稻种植农户的代表性家庭调查，我们的模糊回归不连续分析表明，与单季稻（SR）或双季稻（DR）相比，IDL 家庭中的农户更有可能采用轮作水稻（RR）。在不同的经营规模和专业化农业服务可用性水平下，IDL 的影响各不相同。进一步分析表明，农民的安排与两种潜在的代际向下转移机制有关。用于购买城市住房的货币转移增加了 IDL 家庭的 RR，用于代际育儿的时间转移显著促进了 IDL 家庭的 SR。本研究加深了人们对中国农村劳动力迁移与水稻生产之间关系的理解，为调整水稻生产体系以确保粮食安全提供了参考。
