Research on the Impact of Asteroid Mining on Global Equity Based on Entropy Weight Method and Polynomial Regression

Abstract

It has been 60 years since humankind first entered outer space. Looking back, aerospace workers have made countless sweat and efforts on the way to visit the universe. In the future, if asteroid mining becomes a reality, the resources and wealth contained in it will be enormous. Only by rational distribution and efficient utilization of resources can we fairly benefit the people of the world. In this paper, we define "global equity" as the negative effect of the degree of discretization of the comprehensive strength index of all countries in the world. The global equity index model is established. The model selects the indicators such as economy, politics, education, military strength, and scientific research investment, obtains the weight by using the entropy weight method, calculates the comprehensive strength index of each country, calculates the standard deviation of the comprehensive strength of each country after interval processing, and then negative processing to obtain the global equity index. Then, we verify the model by region. Finally, a prediction model is established for the scale development of the asteroid mining industry, and it analyzes and calculates the profitability of three types of countries after the exploitation of outer space resources. It is included in the calculation of the national strength index to calculate the global equity index in the base year (2020) and 2034-2039. The least-squares cubic polynomial regression fitting is used to show the future trend of the global equity index intuitively. It is concluded that the development of the space mining industry will deteriorate global equity.
