Research on the Benefits of the Olympics

Abstract

The International Olympic Committee (IOC) is facing a decline in the number of applicants for the Summer and Winter Olympics, with recent host cities/countries experiencing various short-term and long-term negative impacts. We have established a grey correlation TOPSIS benefit evaluation model to evaluate the benefits of hosting the Olympic Games in various countries, and to help countries wishing to host the Olympic Games assess their comprehensive benefits. Comprehensive benefit evaluation model for Olympic Games based on grey relevance-TOPSIS: The paper innovatively combines the grey relevance-TOPSIS model with Pearson correlation to establish a grey relevance-TOPSIS evaluation model. Taking the comprehensive benefit evaluation of the Olympic Games as the overall indicator, taking economic benefits, social benefits, cultural benefits, and political benefits as the first level indicators, and taking the subdivision factors of the first level indicators as the second level indicators, a comprehensive benefit evaluation model for the Olympic Games based on grey correlation TOPSIS was established. The paper conducts normalization processing based on the collected data of various indicators, and then obtains the entropy weight of the benefits of hosting the Olympic Games in various countries from 1964 to 2020 to assess the comprehensive benefits of hosting the Olympic Games in various countries.
