경쟁균형지수의 분류와 분석에 관한 연구

Abstract

Purpose: The purpose of this study is to classify and analyze the competitive balance index for measuring competitive balance in sports leagues.BR Method: The competitive balance index was classified and analyzed based on 10 indices related to concentration measurement, 5 indices related to dominance measurement, and 4 indices capable of measuring both concentration and dominance simultaneously.BR Results: The analysis results showed that most of the competitive balance indices can be applied to both open and closed leagues, but some indices cannot. Therefore, cuation is needed when using these indices. For example, indices such as range, relative entropy, Herfindahl-Hirschman Index (HHIC), Herfindahl-Hirschman Index (HHID), and descriptive statistics should not be applied to closed leagues, while indices such as Lorenz curve and Gini coefficient (GD), ANOVA-type measures, and mobility gain function (MGFt) should not be applied to open leagues.BR Conclusion: The competitive balance index is an important method for measuring competitive balance in sports leagues, analyzing the competitiveness and equality among teams in the league, and evaluating various policies and regulations to enhance the league’s competitiveness. Through this, fans can better understand the league’s competitiveness, and league operators can establish policies and regulations to enhance the league’s competitiveness. Therefore, further research on the competitive balance of various sports leagues is necessary based on the research results. These results are expected to provide useful insights to sports league operators, policy makers, and researchers.
