The rapid economic and social development in the past decades has greatly increased the societal acceptance of divorce and non-marital pregnancies in China, which leads to a soaring number of single-parent children. This paper aimed to investigate the impact of having one parent absent on children' food consumption and nutrition status. We extracted 1114 children from a longitudinal household survey data in China, all of which were observed twice. Using the Propensity Score Matching and Difference-in-Difference methods, we found that being raised by one parent does not have a negative effect on children's food consumption and nutrition intake. On the contrary, single-parent families tend to provide more food to their children as a compensation for the absence of one parent and this compensation effect offsets the negative impact caused by declined family income. Particularly, urban, rich families had stronger compensation effect than other families with low and middle incomes.
在过去几十年中,中国经济和社会的快速发展极大地提高了社会对离婚和非婚生育的接受程度,导致单亲子女的数量飙升。本文旨在探讨父母一方缺失对儿童食物消费和营养状况的影响。我们从中国的一项纵向家庭调查数据中提取了 1114 名儿童,这些儿童均被观察了两次。使用倾向得分匹配和双重差分法,我们发现由一方抚养的儿童的食物消费和营养摄入并没有受到负面影响。相反,单亲家庭往往会为孩子提供更多的食物,以弥补一方父母的缺失,这种补偿效应抵消了因家庭收入下降而产生的负面影响。特别是,城市富裕家庭的补偿效应强于其他中低收入家庭。
