| Research Abstract |
Fitting the geographically weighted regression model to the data-sets of car registration rates by municipalities of Japan, it became clear that the important variables determining the level of the rates had not been uniform over the country but had shown the spatial variation, and also that such determinants of motorization had given rise to regional differentiation explicitly. Furthermore it was observed that the regional differentiation of determinants had remarkably changed its structure around 1990. On the basis of above, a simple diagram was obtained from multidimensional scaling to represent the motorization process of the country in geographical context.
