摘　　要：居民食物消费结构的变化,可能会导致食物消费碳排放的变化,进而影响资源环境的可持续性。文章基于1995—2019年长三角城乡居民7大类食物消费数据,探究长三角城乡居民食物消费碳排放差异,采用无条件分位数回归探究不同类型食物的人均消费量对居民食物消费碳排放变化的影响。研究发现:第一,长三角城乡居民食物消费碳排放同时呈现二元性和趋同性特征。第二,低分位食物消费碳排放群体的城乡差异较大,高分位食物消费碳排放群体的城乡差异较小。第三,未来需特别关注低分位农村群体的食物消费碳排放以及高分位城镇群体的食物消费碳排放。The change of residents'food consumption structure may lead to the change of carbon emissions from food consumption,thus affecting the sustainability of resources and environment.Based on 7 categories of food consumption data of urban and rural residents in the Yangtze River Delta from 1995 to 2019,this paper explores the differences in carbon emissions from food consumption of urban and rural residents in the Yangtze River Delta,and adopts unconditional quantile regression to explore the impact of per capita consumption of different types of food on the change of carbon emissions from food consumption of residents.The findings are as follows:First,carbon emissions from food consumption of urban and rural residents in the Yangtze River Delta show both duality and convergence characteristics.Second,there is a large difference between urban and rural areas in the group with low carbon emission from food consumption,and a small difference between urban and rural areas in the group with high carbon emission from food consumption.Third,in the future,special attention should be paid to the carbon emissions from food consumption of rural groups with low scores and urban groups with high scores.
