小売商業活動からみた都市の分類に関する研究

抄録

I think that, the distribution ratio of retail sales in the city is related to the distribution of purchasing power, which is a good reflection of structure of the city. Then, I classify items of goods into some kinds of groups according to correlation of sales in a number of cities. As a technique of classification, I use a component analysis. In this way, I can find the co-ordinate systems that indicate profile values of items of goods on axes. According to their features of distribution ratio of retail sales, each city is located on the co-ordinate systems. Then, through analysis of correlation of profile values of cities and indexes reflecting structure of cities, I think I can get impotant knowledges on planning of commerce in cities.
