本手稿是一篇最初以日文发表（otomo 2021）的论文的英文翻译和扩展版本。近年来，将卫星遥感和大数据应用于经济分析的趋势迅速扩展。特别是，卫星观测到的夜间灯光强度已被证明与关键社会经济指标密切相关，包括国内生产总值、就业率、人口密度以及各国的教育程度。在本文中，我首先概述了计算日本各都道府县和市町村区域夜间灯光强度的方法。接下来，为了评估夜间灯光数据的通用性，我以日本为案例研究，考察了城市级夜间灯光强度与各种公共社会经济指标之间的关系。研究结果表明，夜间灯光强度可以作为这些多样化指标的有效替代指标。最后，我探讨了夜间灯光数据在突发社会中断（如COVID-19大流行）期间实现快速经济影响评估的潜力。
英文摘要
This manuscript is an English translation and extended version of a paper originally published in Japanese(otomo 2021) Recent years have seen a rapid expansion in applying satellite remote sensing and big data to economic analysis. In particular, satellite-observed nighttime light intensity has proven to be closely correlated with key socio-economic indicators, including gross domestic product, employment rates, population density, and educational attainment across countries. In this paper, I first outline the methodology for calculating regional nightlight intensity across Japanese prefectures and municipalities. Next, to evaluate the versatility of nightlight data, I examine the relationship between city-level nightlight intensity and various public socio-economic metrics, using Japan as a case study. The findings suggest that nightlight intensity can serve as a effective proxy for these diverse indicators. Finally, I explore the potential of nightlight data for enabling rapid economic impact assessments during sudden social disruptions, such as the COVID-19 pandemic.
