By defining global equity and other mathematical methods, this paper constructs an equity distribution system for the asteroid mining industry which uses AHP and weight-based Topsis to construct a global equity evaluation model. This model obtains the equity coefficients of 117 countries, which can provide a thorough guiding reference in the distribution of benefits to some degree. Then, the concept of the relative deprivation coefficient is added to the model to adjust the equity of distribution. The model assigns different priorities to countries in the asteroid mining industry, speeding up mining efficiency while improving equity. What’s more, we also combine the models to construct a standard world framework to show the change of global equity coefficient in a century in the phenomenon of ideal asteroid mining. Based on the model we formulate, we conduct an experiment and visualization to show the worldwide change of equity coefficients.
