摘要

This study is to search for the answer of the question of what have made people own more cars in Japan assuming that housing location and conditions affect the car ownership. In this study, a survey was made using the questionnaire replies from families whose housing conditions changed. The contents of questionnaire include indices of houses, indices of home location, household characteristics and number of cars. Then the relationships among the car ownership and the above-considered factors were analyzed. The analysis showed that there are close relations among the number of cars per household and home location, housing conditions and the life stage of the family (which is defined by the number, ages, etc. of the family members). Furthermore, several ownership models were proposed and estimated by using the disaggregate logit model based on the results of the above analysis. The estimated results showed that these models could be applied for the analysis of the structure of car ownership as well as the forecasting of the number of cars holding.
