本文运用修正的AIDS模型,对2001-2011年中国城镇居民不同收入组的食物消费进行了研究。结果表明,随着我国经济社会发展,粮食、油脂类、蛋类、菜类是城镇居民的重要必需生活品,其需求量对价格反应不敏感,刚性消费特征明显;奶类仍是低收入户的奢侈品,不同收入组间肉禽类消费支出弹性没有差异;肉禽类、酒类和奶类需求量对价格变动的反应相对比较敏感;粮食、肉禽类等价格变动对其他食物需求量影响较大,但其影响程度随收入增加而呈减小趋势。在不同社会发展阶段,肉禽类、酒和饮料、干鲜瓜果价格变动对其他食物需求量有较大影响,而粮食、肉禽类、菜类等的需求量受其他食物价格波动的影响较小。
This paper uses a revised AIDS model to study the food consumption of different income groups of Chinese urban residents from 2001 to 2011. The results show that with the economic and social development in our country, grain, fat, eggs and vegetables are important daily necessities for urban residents, their demand is not sensitive to price reaction and their rigid consumption characteristics are obvious. The milk is still low-income households Of the luxury goods, there is no difference in the elasticity of consumption expenditure between the meat and poultry in different income groups; the demand of meat poultry, alcohol and milk is relatively sensitive to the price change; the price changes of grain, meat and poultry have a great impact on other food demand , But its impact decreases with the increase of income. At different stages of social development, changes in the prices of meat and poultry, alcohol and beverages, and dried fruits and fresh fruits have a greater impact on the demand for other foods, while the demand for food, meat and poultry and vegetables is less affected by fluctuations in other food prices .
