ABSTRACT

Our team defines global equity as whether each individual can equally enjoy various resources, including material and non-material resources. We selected 17 indicators from five dimensions: economic, technological, energy, political, and ecological, and used the entropy weight TOPSIS model to score 228 countries and regions at five-time points during 1979-2019. In order to quantify the difference in scores, we refer to and refine the calculation method of the Gini coefficient to derive a Global Equity Index (GEI). We find that the GEI has shown a slight downward trend over the last 40 years.
