Research on Equitable Allocation of Space Resources Based on EWM-TOPSIS

Abstract

It is a question of what happens to the issue of global equity when humans have access to space resources. This paper investigates the issue of global equity based on post-space exploration, develops a global equity model, and explores the future vision of asteroid mining based on this model. Firstly, seven global equity indicators are selected as indicators for the global equity model, and the indicators are dimensionally reduced using principal component analysis, followed by the entropy weighting method (EWM)-TOPSIS to calculate the equity index of the study population and establish a global equity model.
