The Global Equity Evaluation for Asteroid Mining based on Principal Component and Hierarchical Analysis

As scientific and technological development progresses and asteroid mining gradually becomes a reality, the Outer Space Treaty provides the legal basis for promoting the participation of countries in this project. The fairness of this international commitment is fully guaranteed, and the international division of responsibilities among countries is reasonably quantified. Starting from global equity, a comprehensive evaluation based on principal component analysis (PCA) and hierarchical analysis is carried out to reasonably allocate resources based on population, while integrating evaluation scores. Based on K-means cluster analysis, we classify global countries in four dimensions: economic strength, scientific and technological strength, labor input, and industrial output, and based on the classification results, we delineate the international division of labor responsibilities of each country. Based on grey correlation analysis (GCA), the direct factors affecting asteroid mining are assessed as economic strength and industrial output. Based on the results of the above analysis, reasonable suggestions are made to ensure maximum global equity and promote the development of asteroid mining.
