本文介绍了全球城市等级中的黑洞和松散联系的概念。黑洞被定义为人口超过300万的大城市，但不属于世界城市。该文件借鉴了一个分类，使用先进的生产者服务作为世界城市地位的指标。大，非世界城市的确定，并解释他们的立场的临时想法概述。连通性和人口数据用于简单的回归分析，以确定松散的连接：城市的连通性低于其人口的预测。
Abstract This paper introduces the concept of black holes and loose connections in a global urban hierarchy. Black holes are defined as large cities, with a population of over 3 million, that are not classified as world cities. The paper draws upon a classification that uses advanced producer services as an indicator of world city status. Large, nonworld cities are identified, and provisional ideas about explaining their position are outlined. Connectivity and population data are used in a simple regression analysis to identify loose connections: cities whose connectivity is less than that predicted by their population.
