项目摘要

The objective of this research is to analyze the Japanese life structure by estimating Almost Ideal Demand System.This research contains three analyses ;1. The analysis of Japanese consumption structure by AIDS (Almost Ideal Demand System)(1) Characteristics of Japanese workers' households' consumption Structure after 1990A lot of necessity items were independent of other items, but luxury items were notably substitutional or complementary for other items. "Education" was substitutional not only with luxuries but also with some necessity items.(2) The Impact of BSE and Avian Influenza on Food Consumption in JapanThe first BSE outbreak in Japan and in USA had different scale of impact for beef expenditure share. The BSE outbreak in Japan had a great negative impact for beef expenditure in Japan, and it reduced the beef expenditure share both at home and away from home and raised the chicken expenditure share instead.2. The Analysis of One-Person Households' Consumption Structure by AIDS (Almost Ideal Demand System)The age groups over 60 show consumption patterns that are different from those of the other age groups. There is no interaction seen between income and expenses for those over the age of 60 probably because the rate of those owning their own dwelling is high. The cross price elasticity estimates show that many items are independent for those below 34. However, nearly all items are substitution or complementary for those over 60.3. The Analysis of Saving Consciousness by AHP (Analytic Hierarchy Process)The priority of students' consciousness on saving for "Supporting their future life" was the highest, but theirs in the preparation for the risk were scarce. Furthermore, the students' AHP evaluation was characterized by sex, academic year, staying with parents or not, and the saving amount they held.

本研究的目的是通过估计近乎理想的需求系统来分析日本人的生活结构。本研究包含三个分析；1．艾滋病对日本消费结构的分析（近理想需求系统）（一）1990年后日本工人家庭消费结构的特点生活必需品很多是独立于其他物品的，但奢侈品对其他物品的替代或补充作用明显。 “教育”不仅可以替代奢侈品，也可以替代一些生活必需品。 (2)疯牛病和禽流感对日本食品消费的影响日本和美国的首次疯牛病疫情对牛肉支出份额产生了不同程度的影响。日本疯牛病疫情对日本牛肉消费造成较大负面影响，国内外牛肉消费比重下降，鸡肉消费比重上升。2．艾滋病对单人家庭的消费结构分析（近乎理想需求系统） 60岁以上年龄层表现出与其他年龄层不同的消费模式。对于60岁以上的人来说，收入和支出之间不存在交互作用，这可能是因为拥有自己住房的人的比例很高。交叉价格弹性估计表明，许多项目对于 34 以下的项目是独立的。然而，几乎所有项目对于 60.3 以上的项目都是替代或补充的。层次分析法对学生储蓄意识的分析学生“支持未来生活”的储蓄意识优先级最高，但对风险的准备意识却很少。此外，学生的层次分析法评估还以性别、学年、是否与父母同住以及储蓄金额为特征。
