“The very sun irradiates their gorgeous palace, but never bypasses our tatty hut: sunshine is equal.” -Shakespeare
 Equity is the common desire of all people in this world, and it is also a silently tacit agreement between countries and the strategic 
 balance they want to pursue. However, the recent asteroid mining craze seems to be quietly influencing the existing equity degree 
 around the globe. We developed the World Resource Equity Assessment Model (WREAM) and other related models in order to 
 measure the equity degree of the earth as a regional system and to propose policies to regulate it.In this paper, we reviewed the 
 relevant literature, then collected the required data and performed data pre-processing. Next, for the problem we faced, we developed 
 a model that can assess the degree of equity of any regional system. In this model, we combined subjective hierarchical analysis with 
 objective entropy weighting to obtain the weights of each indicator, and then calculated the IP and OP (Input and Output) for each 
 country using the TOPSIS integrated evaluation method. By introducing the Pearson correlation linear coefficients fitted with the 
 one-dimensional linear regression, the degree of global equity was judged by judging the magnitude of the one-dimensional linear 
 regression coefficients. Then, we applied this World Resource Equity Assessment Model to 10 countries. we made predictions for 
 possible future visions of asteroid mining for pre-policy interventions and post-policy interventions.
