摘要翻译：
紧凑型城市作为一种可持续发展的概念，旨在提高城市功能的效率。然而，以往的研究更多地集中在形态上，而不是结构上。本研究着眼于城市结构要素，即由高密度和高强度的社会经济区域组成的城市热点，并探讨其空间结构与经济绩效的关系。利用夜间光度(NTL)数据和Loubar方法对热点进行识别和提取，最终得出两个结论。首先，随着人口的增加，我国、欧盟和美国无论在哪个地区，热点数量都呈亚线性增长，其指数约为0.50～0.55，但其相交值却完全不同，这主要是由于经济发展水平的不同所致。其次，我们论证了热点区域的紧致性对经济增长的倒U型影响，这意味着存在一个最优的紧致系数。这些发现对城市规划有一定的帮助。

英文摘要：
The compact city, as a sustainable concept, is intended to augment the efficiency of urban function. However, previous studies have concentrated more on morphology than on structure. The present study focuses on urban structural elements, i.e., urban hotspots consisting of high-density and high-intensity socioeconomic zones, and explores the economic performance associated with their spatial structure. We use nighttime luminosity (NTL) data and the Loubar method to identify and extract the hotspot and ultimately draw two conclusions. First, with population increasing, the hotspot number scales sublinearly with an exponent of approximately 0.50~0.55, regardless of the location in China, the EU or the US, while the intersect values are totally different, which is mainly due to different economic developmental level. Secondly, we demonstrate that the compactness of hotspots imposes an inverted U-shaped influence on economic growth, which implies that an optimal compactness coefficient does exist. These findings are helpful for urban planning.
