本文采用线性近似二次型几乎理想需求系统模型（LA/QUAIDS）对日本家庭非酒精饮料的需求量进行了估算。在2000年1月至2013年3月期间，对49个城市的两个或两个以上家庭的非酒精饮料组：绿茶、红茶、茶饮料、咖啡、咖啡饮料、果蔬汁、碳酸饮料和牛奶进行了8个支出份额和价格需求方程的估算。消费弹性结果显示，绿茶（2.320）、红茶（1.357）、咖啡（1.090）和果蔬汁（1.019）是日本家庭的奢侈品，而茶饮料（0.836）、咖啡饮料（0.896）、碳酸饮料（0.844）和牛奶（0.677）是日本家庭的必需品。人口统计效应显示，18岁以下的人更喜欢牛奶（5.928）比任何其他饮料，而老年人往往喝更多的绿茶（24.427）。此外，温度效应在大部分月份对茶饮料、咖啡饮料、果蔬汁和碳酸饮料的需求影响主要为正，对绿茶、红茶和咖啡的需求影响主要为负。
This paper estimates the demand of non-alcoholic beverages in Japanese household using the linear approximation quadratic almost ideal demand system model (LA/QUAIDS). Eight expenditure shares and prices demand equations for non-alcoholic beverage group: green tea, black tea, tea beverage, coffee, coffee beverage, fruit and vegetable juice, carbonated beverage and milk are estimated for two or more households in forty-nine cities for the period January 2000 through March 2013. The expenditure elasticity results indicate that green tea (2.320), black tea (1.357), coffee (1.090) and fruit and vegetable juice (1.019) are luxury goods while tea beverage (0.836), coffee beverage (0.896), carbonated beverage (0.844) and milk (0.677) are necessities in the Japanese household. The demographic effects reveal that people under the age of 18 prefer milk (5.928) than any other beverages whereas elderly people tend to drink more green tea (24.427). Moreover, temperature effects shows it has mostly positive effect on demand for tea beverage, coffee beverage, fruit and vegetable juice, and carbonated beverage and negative effect on green tea, black tea, and coffee in most of the months.
