Research on the Impact Mechanism of Asteroid Mining on Global Equity under the Comprehensive Evaluation System

Abstract

In order to scientifically measure the global equity connected with asteroid mining, we establish a comprehensive evaluation system of global equity based on five criteria layers involving economic, environmental, educational, social, and health. We also measure the Global Equity Index (GEI) based on entropy weight method and AHP. The countries are grouped into three categories according to GEI. We Use grey relational analysis to screen out the indicators of significant impact of GEI for different categories of countries, and deeply study the mechanism of asteroid mining on global equity. For the definition and analysis of Global Equity, this paper comprehensively evaluates the level of global equity from five aspects involving economy, environment, education, society, and health. This paper selects representative indicators such as GDP per capita, resident consumption per capita, carbon dioxide emissions, forest area, etc., and uses the entropy weight method and the analytic hierarchy process to quantify the level of sample country’s equity. We select the developed and developing countries of each continent respectively, multiply the scores of each sample by the corresponding number of developed or developing countries in its continent, we use weighted average to arrive at the equity score of one continent and the global equity score finally. For the future vision for asteroid mining, we will describe in detail the subjects, costs and benefits, resource division, and profit distribution of the asteroid mining. After using the entropy weight method to determine weights, we screen out indicators which produce a significant impact on global equity, and analyze the impact mechanism of asteroid mining on global equity. For the future impact of asteroid mining, we divide countries into three categories: countries with high equity level, medium equity level, and low equity level by clustering. We use grey correlation analysis to find the indicators that have a significant impact on the GEI of different countries, and analyze the impact of the three-stage changes in asteroid mining on these three types of countries.
