马旺林 郑宏运：非农就业是否促进了中国农村地区水果和蔬菜的消费？

Wanglin Ma, Hongyun Zheng (2021). Promoting fruit and vegetable consumption in rural China: Does off-farm work play a role? Q Open: A Journal of Agricultural, Climate, Environmental, Food, Resource, and Rural Development Economics, 1(2): 1-21

摘要：

尽管非农就业在促进农业生产和农村发展以及提高农户福利等方面起到了重要作用，但对其能否促进发展中国家农村地区的水果和蔬菜消费仍知之甚少。利用两阶段残差引入法和来自中国的558个农户调研数据，本文分析了非农就业对果蔬消费（购买频率和消费支出）的影响。结果表明，户主非农就业通过增加购买频率和支出促进了农村家庭的果蔬消费。进一步分析证实户主而非其他家庭成员的非农就业在影响家庭果蔬消费上起到了决定性作用。本文还发现农户的果蔬种植行为与购买行为存在相互替代关系。

Abstract

Although off-farm work plays a significant role in facilitating agricultural production and rural development and improving household welfare, little is known about whether off-farm work can promote fruit and vegetable consumption in rural areas of developing countries. This paper sheds new insights by estimating the impact of off-farm work on fruit and vegetable consumption, measured by purchasing frequencies and consumption expenditures. We employ a two-stage residual inclusion estimator to address the self-selection bias and analyze data collected from 558 rural households in China. The results show that household heads’ off-farm work promotes rural households’ fruit and vegetable consumption by significantly increasing purchasing frequencies and expenditures. Further analysis confirms that household heads' off-farm work participation, rather than all household members, plays a prominent role in promoting household fruit and vegetable consumption. We also find that farmers’ behaviours of growing fruits and vegetables appear to substitute their purchasing behaviours.
