新的城市结构模式的出现是基于这样的假设：大都市区日益分散，中央商务区在就业方面变得不那么重要，城市边缘出现新的副中心。本文提出了一种确定郊区副中心的方法。然后将这一方法应用于欧洲中等城市外围是否存在次中心的问题，如果存在，在那里有哪些活动。这是通过实证描述和解释比利时四个城市区域的空间结构来实现的。在不同级别的数据聚合中使用了几种空间分析技术。局部自相关特别适合于检测就业集群，而偏离-份额分析对于观察发展趋势是有用的。我们表明，尽管总体上有去中心化的趋势，但多中心主义仍然薄弱。
New models of urban structures have emerged based on the assumption that metropolitan areas are increasingly decentralized, central business districts becoming less important in terms of employment and new subcentres emerging at the edge of cities. This article presents a method of identifying subcentres in suburban areas. This method is then applied to the question of whether subcentres exist on the periphery of medium-sized European cities and, if so, what kind of activities are located there. This is done by empirically describing and explaining the spatial structure of four urban regions in Belgium. Several spatial analysis techniques are used at different levels of data aggregation. Local autocorrelation is particularly appropriate for detecting clusters of employment, while shift-and-share analyses are useful for looking at the developmental trends. We show that, despite an overall trend to decentralization, polycentrism is still weak.
