摘要
通过构建修正的AIDS模型,利用1992-2005年西部城镇地区居民食品消费的面板数据,实证研究了影响其食品消费的作用因素和机理。结果表明,西部城镇居民肉类和主粮消费支出份额较大,奶类和水产品支出份额较小;主粮支出和自价格弹性绝对值较小,而奶类和水产品支出和自价格弹性绝对值较大;家庭特征变量对居民食品消费的影响比较显著,最后得出相关启示。
Mainly by constructing modified AIDS model, panel data of foods consumed by urban residents in the West from 1992 to 2005 are used to empirically analyze the influential factors and mechanism of food consumption. The empirical analysis results show that consumption expenditure shares of meats and staple food grain are very big, that those shares of milks and aquatic products are relatively small, that elasticity absolute values of expenditure and self - price of staple food grain are comparatively small, but elasticity absolute values of expenditure and self- price of milks and aquatic products are comparatively big, and that influence of family characteristic variables on residents＇ food demand is relatively significantly. Finally, some suggestions are put forward.
