摘要
[目的]为了厘清贫困地区外出务工与农户食物消费的关系,文章以西部贫困地区为例,研究外出务工对农户食物消费的影响。[方法]该文使用陕西省镇安县、洛南县,云南省武定县、会泽县和贵州省盘县、正安县2015年1 368户农户实地调研数据,将在家成员作为研究对象,采用倾向得分匹配法(PSM)调整样本的选择性偏差,降低内生性导致的估计偏误,分析外出务工的影响效果。[结果]采用最近邻匹配法、半径匹配法和核匹配法进行匹配后,发现外出务工使农户的人均食物消费总支出的对数最多显著提高0. 081%,最少显著提高0. 060%。[结论]外出务工主要通过收入变化、外来的信息或经验和人口变化3方面影响农户的食物消费,且西部贫困地区外出务工显著提高农户的食物消费水平。相关部门应关注贫困地区农户食物消费与营养状况,改善其食物消费结构,提高食物安全与营养水平。
The aim of this paper was to figure out the relationship between migration and the food consumption of household in poor rural areas of China.Household survey was conducted in six poor counties:Zhen′an,Luonan in Shaanxi province,Wuding,Huize in Yunnan province,and Pan,and Zheng′an in Guizhou province in 2015.Survey data of randomly selected 1368 households was used for the analysis.Propensity Score Matching was used in order to reduce the endogeneity bias of sample selection.The results indicated that by using k-nearest neighbor matching,radius matching and kernel matching methods,the migration significantly improved total food expenditures per capita by 0.060%to 0.081%.Migration affected food consumption mainly by income changes,external information/experience,and population changes.Migration in poverty-stricken areas of west China significantly improved the food consumption of households.It′s necessary to pay attention to the status of food consumption and nutrition in poor areas,take measures to improve their food consumption structure,and raise the level of food security and nutrition.
