Abstract
PurposeThis paper aims to examine impacts of the poverty alleviation relocation (PAR) program on diet quality of low-income households in China. We explore the impact mechanism of relocation on diet quality and the heterogeneous effects of different relocation modes.
Design/methodology/approachA fixed effects model is constructed using panel data of 1126 low-income households collected over three years in eight provinces of China. The PAR program provides a natural experiment which dramatically changes the living conditions surrounding farmers. We are able to identify the causal effects of relocation on diet quality free from selection bias.
FindingsThe empirical results show that the PAR program improves diet quality of low-income households and that better market access and increasing incomes induced by relocation play an important role in this improvement. Improved market access significantly reduces the over-consumption of staple foods, whereas higher income significantly reduces the intake divergences of non-staple foods. The impacts of different relocation modes on diet quality are highly heterogeneous.
Practical implicationsOur findings indicate that the PAR program benefits diet quality of low-income households through greater market access and increases in total household income. Market improvements and food subsidies are conducive to improving the diet quality of the low income.
Originality/valueDespite widespread evidences of healthy diets being associated with household environments and income, selection bias remains. This paper utilizes an exogenous program to explore the causal impacts of market access and family income on diet quality and to separate their different effects.

摘要
宗旨:本文旨在研究易地扶贫搬迁项目对中国低收入家庭饮食质量的影响,探讨扶贫搬迁对饮食质量的影响机制,以及不同扶贫搬迁模式的异质性影响。设计/方法/途径:利用三年来在中国8个省收集的1126个低收入家庭的面板数据,构建了一个固定效应模型。PAR计划提供了一个自然实验,极大地改变了周边农民的生活条件。我们能够识别搬迁对饮食质量的因果效应,而不存在选择偏差。研究结果:经验结果表明,PAR方案改善了低收入家庭的饮食质量,而更好的市场准入和搬迁带来的收入增加在这种改善中发挥了重要作用。市场准入的改善显著降低了主食的过度消费,而收入的提高则显著降低了非主食的摄入差异。不同搬迁模式对饮食质量的影响具有高度的异质性。实际意义:我们的研究结果表明,PAR计划通过扩大市场准入和增加家庭总收入,有利于提高低收入家庭的饮食质量。市场改善和食品补贴有利于提高低收入者的饮食质量。原创性/价值:尽管有广泛的证据表明健康饮食与家庭环境和收入有关,但选择偏差仍然存在。本文利用外生程序,探讨市场准入和家庭收入对饮食质量的因果影响,并分离它们的不同影响。关键词
