Research on the Global Equlty Index Model

Abstract

In the current situation, the earth ' s resources will be exhausted one day. There are tens of thousands of asteroids in the universe. According to the current scientific research, the asteroid mining industry has its advantages. However, how to mine and in what proportion to distribute mining profits in various countries is the key to promoting global equity. Therefore, based on the reality of different levels of development in various countries, our goal is to establish a Global Fair Index to measure the degree of equity, and use this index as a standard to realize the practical problem of asteroid mining promoting global equity. First of all, we define global equity as that low-score weak countries have more opportunities to reach the average level, and advantageous countries should allocate economic resources to low-score countries to achieve global equity. To measure global equity, we introduce typical countries and regions with different levels of development (countries and regions included in the G20) to establish standard world models. Through the theory of hierarchy need, global equity is divided into Sanitation & Safety, Economic development, social equity, Education & Technology, Sustainable development, Five dimensions. Secondly, we develop a Global Fair Index Model to measure the degree of global equity. Combined with Five Demand Level, through the Entropy Weight Method, the weight of different levels is calculated, and then the Entropy Weight Method and TOPSIS Evaluation Model are used to calculate the satisfaction score of the Five Demands Level of each country. By calculating the average score of each country's demand satisfaction, the Global Fair Standard Point (0.025862938) is obtained. Each country can compare with the Global Fair Standard Point to understand its position in the global average demand level, that is, the definition of low-score weak countries and advantageous countries. Then, drawing on the standard deviation formula, we calculate the composite score reflecting the degree of satisfaction of countries ' needs over a period of time (point) on the discreteness of the global equity standard point, that is, the Global Fair Index. (The lower the Global Fair Index, the smaller the international differences, which means that the world is more equitable.)
