Harmonized luminosity and economic activity across provinces in China: Cross-sectional differences, regional time series, and inequality dynamics

Satellite images of lights at night can track how China's provinces grow, but the link between light and income shifts over time and weakens during downturns. Newer satellite data measure economic activity more accurately than older data, especially for industry and services.

Exploring Economic Activity from Outer Space: A Python Notebook for Processing and Analyzing Satellite Nighttime Lights

This paper introduces a user-friendly geocomputational notebook that illustrates how to process and analyze satellite NTL images.

Can higher-quality nighttime lights predict sectoral GDP across subnational regions? Urban and rural luminosity across provinces in Türkiye

This study explores the potential of higher-quality nighttime light (NTL) data to predict economic activity across various sectors within regions.
