新建超市影响居民消费的研究

以简单数学模型来分析新建超市如何吸引附近居民前往购物,探讨之影响因子有两超市相隔距离与占地面积比率。别于前人研究,超市所在城市区域为一有限范围。研究结果指出:为吸引更多居民惠顾,若新建超市面积较大或与旧者相同时,其座落位置应尽可能靠近旧超市;反之,则存在临界位置,当新超市盖予其处时,所能影响之范围最大,若新超市面积小,与旧超市距离应加大。

A Study on Populace Shopping for a New Supermarket

A simple mathematical model is developed in the present study to deal with the impacts of a new supermarket upon the populace. The factors include the distances between the two shops and the ratios of the two shop areas. Rather than those conclusions in the past, the location of the shop in the city is a finite area. The results point out that, when the new shop spans an area larger than or equal to that of the old ones, the distances between the shops should be as small as possible for the new shop to attract city people. If the area of the new shop is smaller than that of the old, critical positions exist for which the new shop has a maximal influence sphere. Furthermore, the new shop with smaller areas must be constructed farther from the old one.
