摘要：

已有研究表明收入对农村居民食物消费有显著的影响，然而关于农村居民收入及收入分布的动态变化对农村居民食物消费的影响却比较少见。本研究基于中国健康与营养调查数据，运用二次型近乎理想需求模型（QUAIDS）估计不同收入组成年农民居民各类食物收入弹性，并对模型的支出内生性问题和零值消费问题进行处理。结果表明，农村居民收入及收入分布的变化对其食物消费有显著影响。除粮食类食物外，其余食物类别（蔬菜类，油脂类，动物性食物类、其他食物类）的收入弹性均显著为正。农村居民收入阶层的跃迁将导致农村居民粮食类、蔬菜类、油脂类和动物性食物类收入弹性的下降。基于估计的收入弹性，农村居民收入组别的变化对食物消费影响的动态模拟结果显示，降低农村地区收入不平等程度将有助于改善农村居民的食物营养状况。


Abstract:

Previous studies have demonstrated that income has a significant effect on food demand in rural China.  However, little research has focused on the dynamic impact of income and income distribution on food demand in rural China.  Using China Health and Nutrition Survey data, this study employs a consistent two-step quadratic almost ideal demand system model, with addressed problems of endogeneity of total expenditure and zero shares, to estimate the food demand elasticities among adults in rural areas with regard to the different income strata.  The results show that changes in income and income strata have significant effects on food demand in rural areas.  Except for grains, all other food groups, including vegetables, oils and fats, animal products, and other foods, have positive income elasticities, and the rise in the income strata will lead to declining income elasticities for grains, vegetables, oils and fats, and
