| Outline of Final Research Achievements |
This study organizes cohort data of car ownership in Japan from 1980s to present. This study firstly examines the correlation analysis between car ownership and demographic data. As a main result of regular and compact passenger cars and compact four-wheel cargo, positive relationship is found for income and population density; negative relationship is found for car age, consumer price index, gasoline price, average family size, population size, train and bus uses; ambiguous relationship is found for net immigration rate and rate of old person. This study next examines the elasticities with respect to car price and fuel efficiency for car purchase (market share) by random-coefficient logit model and the elasticities with respect to car ownership tax and fuel efficiency for car ownership (numbers) by dynamic cohort model, respectively.
