World Equity from Stars

Abstract

More than 100 countries around the world ratified and signed the United Nations Outer Space Treaty in 1967, and with the increasing access of human beings to space-based resources, it is unclear whether this international commitment to equity is still valid. Based on scholars' research on the concept of equity, the variance of each country's development level is used to measure global equity. Eight indicators such as gross domestic product (GDP) and physician density were selected to obtain the corresponding weights through the entropy weight method, thereby obtaining the National Development Index (NDI) of the selected 224 countries. In addition, this paper selects 23 representative countries as samples to explore the link between asteroid mining and global equity, and uses energy use, the percentage of total domestic R&D expenditure in GDP, and the number of satellites launched as the scientific and technological capability index (STCI), and the Appropriate weights were derived using Analytic Hierarchy Process (AHP) as each country acts as a bridge between asteroid mining and global equity. The Lotka-Volterra model is used to establish a perfectly competitive differential equation for the mining of sample countries, and the changes in share from the perspective of per capita GDP and unemployment are used to evaluate the impact of global equity after the introduction of asteroid mining. Finally, this paper formulates international cooperation policies for different types of countries. Build a Shapley model for distribution of benefits, proving the effectiveness of a given policy in promoting global equity and maximizing the world's interests.
