本文的目的是通过估计线性近似理想需求系统（LAIDS）模型来分析1980-1989年和1990-2002年两个时期的食品消费模式。笔者使用了《家庭收支调查年度报告》中编制的10个区的职工家庭数据。实证结果表明，熟食和外食（FAFH）在1980-1989年间是奢侈品。但值得注意的是，1990-2002年间，熟食对收入和价格变化均没有做出反应，这一事实表明熟食已成为人们饮食生活的必需品。在此期间，包括酒精饮料在内的熟食和饮料成为FAFH的强有力替代品，并且这些食品的交叉价格弹性在此期间比1980-1989年更高。 FAFH 的补充是谷物和水果。 1990年至2002年期间，关东地区鱼类和贝类的支出份额往往小于其他任何地区。另一方面，关东地区的FAFH份额往往高于其他任何地区。（2004年5月31日接收；2005年5月9日修订版接受）
The objective of this paper is to analyze the food consumption patterns during two periods of 1980-1989 and 1990-2002 by estimating a Linear Approximate Almost Ideal Demand System (LAIDS) model. The author used the workers' household data from 10 districts compiled in Annual Report on the Family Income and Expenditure Survey. Empirical results show that cooked food and food away from home (FAFH) were luxury items in 1980-1989. But it is to be noted that the cooked food failed to respond either to income or to price change during 1990-2002, the fact of which shows that the cooked food became a necessity in the dietary life. Cooked food and beverages including alcoholic beverage became strong substitutes for FAFH during this period, and the cross price elasticities of these items became higher during this period than in 1980-1989. Complementing FAFH were cereals and fruits. The expenditure share of fish and shellfish in Kanto tended to be smaller than in any other districts during 1990-2002. On the other hand, FAFH share in Kanto tended to be higher than in any other districts.(Received May 31, 2004; Accepted in revised form May 9, 2005)
