Measuring the Congruence of Market Areas
提出了评估共享同一分销点的两个市场区域边界重合程度的方法，可用于检验市场区域在不同维度（如产品、日期或时间段）上的变化，并给出了四种市场区域大小和重叠的度量指标及分解边界差异的统计方法。
Methods are proposed for assessing the boundary coincidence of two market areas that share the same distribution point. These methods may be used to test whether market areas vary in different dimensions such as products, days, or time periods. Four measures of market area size and overlap are presented, along with a statistical method for decomposing market boundary differences. The measures are illustrated using an example.
