中心商店街の顧客吸引力からみたシェアとそのタイプ

In the cities which have the same population and functions, it is found that the central shopping streets in some cities are more thriving than the ones in other cities. And so, the writer intends to explain the relation between the central shopping streets and subsidiaryshopping streets in the cities.<br> To attain this aim, after selecting high quality shops which deal in watches, spectacles, precious metals, etc. and drugstores which deal in daily necessaries in the central shopping streets, the writer has calculated the ratio of the former shops (A) to the latter ones (B), using the formula A/B×2 for the customer attracting power (“2” denotes the ratio of the B consumers of A store to B).<br> The investigations treated here may be summarized as follows:<br> (1) As the city population increases, the index of customer attracting power also tends to increase except for giant cities: the indexes of the customer attracting power are about 10 for one-million cities, about 7-8 for 500-300 thousand, about 5 for 300-500 thousand, about 2 for cities with less than 100 thousand population.<br> (2) The index of the customer attracting power for the central shopping streets is not always related with the concentration of amusement (pachinko houses, movie theatres, etc.), but is related with the numbers of pedestrians on the central shopping streets ; it is also related with the index of the customer attracting power in the central business districts and with the sizes of the urban regions hinterlands for smaller and medium-sized cities.<br> (3) From the shares of the customer attracting power of the central shopping streets to the subsidiaryshopping streets in each urban region, the writer has found out the characteristics of the local concetration and decentralization of shopping function in each urban region.<br> (4) It has been found that the index of the customer attracting power for the central shopping streets in each city is generally ralated with the average land-value of the same streets, and the writer found the following types for the shares of the customers in the central shopping streets in each urban region by means of the land-value insted of the customer attracting power : a¹…… Sapporo type, a² …… Sendai type, a³ …… Fukushima type, b¹…… Hiroshima type, b²…… Fukuyama type, c…… Shizuoka type.<br> How the intensity of the customer attracting power in the central shopping streets to the subsidiaryshopping streets in the urban region is influenced by the concentration of the means of transportation, such as buses, tram-cars, etc., the combination of the various functional streets, the custom of the consumers and the commercial conditions of the urban region and its hinterland is not yet analyzed and it awaits future researches.
