This study investigates the impact of the 2018 summer heat wave on urban mobility in Seoul and the role of economic complexity in the region’s resilience. Analysis of subway and mobile phone data reveals a significant decrease in the floating population during the extreme heat wave, underscoring the thermal vulnerability of urban areas. However, urban regions with higher complexity demonstrate resilience, attracting more visitors despite high temperatures. Our results suggest the centrality of economic complexity in urban resilience against climate-induced stressors. Additionally, high-complexity small business clusters appear to serve as focal points for sustaining urban vitality in the face of thermal shocks within the city. From a long-term perspective, our results imply that people might become more concentrated in highly complex regions in the era of global warming.

热浪期间城市内高复杂度区域的人口集中
本研究调查了 2018 年夏季热浪对首尔城市交通的影响,以及经济复杂性在该地区韧性中的作用。对地铁和手机数据的分析显示,在极端热浪期间,流动人口显著减少,凸显了城市地区的热脆弱性。然而,复杂度较高的城市地区表现出韧性,尽管高温,但仍能吸引更多的游客。我们的结果表明,经济复杂性在城市抵御气候诱发压力源的韧性中处于中心地位。此外,面对城市内的热冲击,高度复杂的小企业集群似乎是维持城市活力的焦点。从长期来看,我们的结果表明,在全球变暖的时代,人们可能会更加集中在高度复杂的地区。
