NEW COMPETITION IN SHOPPING‐CENTER HIERARCHIES: AN EMPIRICAL COMPARISON OF ALTERNATIVE SPECIFICATIONS*
在购物中心层级框架内，利用Voronoi图定义新进入者对现有中心的侵犯程度，并通过logit分析检验不同侵犯类型与中心属性（如人口、营业额、年龄、层级）的关系。
ABSTRACT. Within the framework of an existing hierarchy of shopping centers, Voronoi diagrams at each level of the hierarchy are used to define infringement on existing centers by new entrants. We distinguish four intensities of infringement—that is, four categorizations of when existing centers face new competition—and label shopping centers accordingly. Our aim is to determine empirically which type of new competition is best explained by various attributes of the incumbent centers. To accomplish this, logit analysis is used to relate the above labels to market‐area population, store turnover, age, and hierarchical level of each shopping center in Edmonton, Alberta.
