A geographical study about the diversification of a retail type and the location in Tokyo metropolitan area

第1章和第2章的分析是基于5家大型连锁便利店提供的销售点数据。这项研究的数据来自东京大都会地区的287家门店，而该连锁店在同一地区经营着数百家门店。通过对商品组销售模式多样性的分析，提出了店铺类型的分类。根据拟议的商店类型，系统地解释了销售模式多样性与商店位置之间的相关性。通过商品组因子分析的结果，提出了解释便利店销售模式的五个因素，并根据各因素负荷的聚类分析结果，将便利店分为七个类型。据说，便利店凭借其一站式购物的优势，获得了超市和其他竞争对手的部分潜在销售额。通过对POS数据的分析，证明了这一论断。便利店在功能上的这些方面基本上反映了零售商在当地市场的竞争。但值得注意的是，年轻顾客的选店行为模式与年长顾客有所不同。值得注意的是，一些便利店的销售模式昼夜变化明显，白天是上班族或大学生的需求，晚上是当地居民的“替代”需求。在第三章中，我考察了“shop99”的经营条件特征、区位策略和成长可能性。因此，在东京都市圈，“SHOP99”可以开店的地方仍然很多，潜在的数字850在附近上升。但当地城区人口密度低，SHOP99作为目标的小户较少。因此，SHOP99可以开店的空间非常小。

Analysis in Chapter. 1 and 2 are based on the POS (point-of-sales) data supplied by 5 large convenience store chains. The data from 287 stores around the Tokyo metropolitan area are available for this study, while the chain operates several hundred stores in the same area. Classification of store types is proposed through the analysis of diversity in the pattern of sales by commodity groups. Along the line of the proposed store types, systematic interpretation is given for the correlation between diversity in the pattern of sales and that in the store locations.The result of factor analysis by the commodity groups suggests five factors to explain the sales patterns of convenience stores, and according to the result of cluster analysis on each factor loading, stores are classified into the seven types.Convenience stores, with its advantage in one-stop shopping, are said to acquire a part of potential sales of supermarkets and other competitors. This assertion has been proved through the analysis of POS data. Such aspect in the functions of convenience stores basically reflects the retailers' competition in the local market. It is noteworthy, however, the younger customers show different pattern of store choice behavior from older ones. It is also notable that some convenience stores show a clear-cut change in sales patterns by day and night, with office workers' or college students' needs in the daytime and local residents' 'replacement' needs at night.With Chapter 3, I examined a business condition characteristic, a location strategy, and growth possibility about "shop99". As a result, In Tokyo metropolitan area, the place where "SHOP99" could open a store was still had a lot, and potential number 850 rose near. However, population density is low in the local city zone, and there are few small households which SHOP99 assumes a target. On this account there is remarkably little room where SHOP99 can open a store.
