The economic output in a country or region is its accumulation of created economic values within a certain period of which, Gross Domestic Product (GDP), is the most prevalent indicator globally. Facilitated by social organization and order, humans use labor and other production resources to exchange goods and services to create, transform, and achieve economic value.

Subsequently, from a revised real growth perspective, we employed a top-down method to calculate global 1вЂ‰kmвЂ‰Г—вЂ‰1вЂ‰km gridded revised real GDP and electricity consumption during 1992вЂ“2019 based on our calibrated nighttime light data.Д®conomic activities are essential for human survival and development 1.

In this study, we employed a series of methods, such as a particle swarm optimization-back propagation (PSO-BP) algorithm, to unify the scales of DMSP/OLS and NPP/VIIRS images and obtain continuous 1вЂ‰kmвЂ‰Г—вЂ‰1вЂ‰km gridded nighttime light data during 1992вЂ“2019. Simultaneously, the Defense Meteorological Satellite ProgramвЂ™s Operational Linescan System (DMSP/OLS) and National Polar-orbiting PartnershipвЂ™s Visible Infrared Imaging Radiometer (NPP/VIIRS) nighttime light data, adopted in these studies as a proxy tool, still facing shortcomings, such as imperfect matching results, discontinuity in temporal and spatial changes. However, such gridded data have shortcomings, including overestimating real GDP growth, ignoring the heterogeneity of the spatiotemporal dynamics of the grid, and limited time-span. Some scholars have estimated gridded GDP and electricity consumption. As fundamental data, gross domestic product (GDP) and electricity consumption can be used to effectively evaluate economic status and living standards of residents.
