【摘要】：本研究基于国家统计局2007~2009年城镇居民住户调查中不同收入层次农民工样本,运用二次型近似理想需求系统模型(QUAIDS)对其家庭食物消费的影响因素进行了实证分析。研究结果表明,全部农民工样本的各类食物支出弹性均显著为正,且随着收入的增加,农民工的粮食和蔬菜的支出弹性值呈增加趋势,畜产品呈减少趋势,食用油呈先减少后增加的趋势;农民工的各类食物自价格弹性均显著为负,且总体来看农民工对食用油的价格变化最为敏感,但低收入家庭对蔬菜的价格变化更为敏感。本文的政策建议是,在城镇化不断推进的过程中,政府有必要确保城镇地区食物供应总量和增量,尤其是要制定确保蔬菜、粮食和食用油预期增量有效供给的相关对策措施,并强化和完善城镇地区食物价格监测和调控机制。
[Abstract]:Based on the samples of migrant workers with different income levels in the 2007 ~ 2009 urban household survey of the National Bureau of Statistics, this study empirically analyzed the influencing factors of household food consumption by using Quadric approximate ideal demand system (QUAIDS) model. The results showed that the elasticity of all kinds of food expenditure of all migrant workers was significantly positive, and with the increase of income, the expenditure elasticity of food and vegetables of migrant workers showed an increasing trend, and the animal products showed a decreasing trend. The price elasticity of all kinds of food of migrant workers was significantly negative, and the peasant workers were most sensitive to the price change of edible oil, but low-income households were more sensitive to the change of vegetable prices. The policy suggestion of this paper is that, in the process of urbanization, it is necessary for the government to ensure the total amount and increment of food supply in urban areas, especially to formulate relevant countermeasures to ensure the effective supply of expected increase in vegetable, grain and edible oil. And strengthen and perfect the food price monitoring and control mechanism in urban areas.
