Analysis of National Performance Efficiency of College Judo Athletes : Application of data envelopment analysis

The purpose of this study is to analyze the performance efficiency of countries that participated in the induction events of the World University Games by applying the data envelope analysis model. To this end, the recent 5 World University Games and Universiade Games were selected as research data. Data envelope analysis was conducted by selecting the number of population as input variables, GDP per capita, and the number of medals as output variables. Spearman&quots rank correlation analysis was conducted to find out the correlation between the medal ranking and the efficiency ranking, and a scatter plot was presented for comparative analysis. The analysis used EMS 1.3 and SPSS 22.0 programs. In addition, Spearman&quots rank correlation analysis was conducted to find out the correlation between the medal ranking and the efficiency ranking, and a scatter plot was presented for comparative analysis. As a result, first, Mongolia and Uzbekistan showed the highest efficiency index. Second, the reference variables of Mongolia and Uzbekistan were the highest. Third, it was found that there was a correlation between medal rankings and efficiency rankings. The results of this study can be said to be meaningful in that it analyzed the performance in terms of the efficiency of university induction competitions between countries. In the future, it is judged that it will be usefully used in the process of selecting a reference country in proposing sports policies between countries of similar scale.
