摘　　要：将农村青少年儿童分为普通儿童、留守儿童和随迁儿童三种类型,利用2015年青海、陕西和河南三省1 104名学生的调查数据,对不同农村青少年儿童的饮食规律和荤素搭配状况进行比较分析。为克服样本自我选择偏误问题,采用多分类Logit模型估计不同家庭结构的广义倾向值,并将其倒数作为抽样权重。结果表明:与普通儿童、随迁儿童相比,留守儿童的三餐饮食规律较好,但荤素搭配则较差;母亲受教育程度对农村青少年儿童的饮食规律和荤素搭配产生显著的正向促进作用;家庭经济水平越高,则农村青少年儿童荤素搭配越好。In this paper,we divided rural children into three types：average children,left-behind childrenand urban migrant children according to their household structure.Then we analyzed how household structureaffects the rural children’s diet quality with survey data collected of 1 104 students in Qinghai,Shaanxi andHenan Province in 2015.Notably,in order to overcome the problem of sample selection bias we adoptedthemultiple classification logit model to get the general tendency value of different household structure and definethe value’s inverse as sample weights.Finally we reached three conclusions.First,rural left-behind childrenenjoy a better dietary,whose diet balance is poor compared to that of the average children and urban migrant children.Second higher education level of rural children’s mother will lead to a better dietary and balanced di-et.Finally the richer the family is,the more balanced the children’s diet is.
