Medal Forecasts and Competition Strategies for Chinese Athletes in the Beijing 2022 Winter Olympic Games——Based on Olympic Home Advantage

This paper analyzes the host countries of the last 10 Winter Olympic Games from 1984 to 2018(namely the ⅩⅣ to ⅩⅩⅢ Olympic Winter Games),systematically reviews the home advantage indicators including the number of gold medals,the number of medals,countries' ranking positions as well as their performance in different winter sport disciplines.The cause of such home advantage has been studied from multiple perspectives such as government elite sports policies and investments,support of the home audience,familiarity with the venues as well as the size of the home team,and a logit regression model has been built to forecast that the Chinese athletes will win the biggest share of medals in history in the Beijing 2022 Olympic Games.Based on the experience of the host country of the Winter Olympic Games,this paper puts forward the strategies for Chinese athletes to prepare for the Beijing 2022 Winter Olympic Games and create the best performance in the Winter Olympic Games:1) An appropriate response to the COVID-19 epidemic should be strengthened to meet the goal of best sport performance;2) dominant sport disciplines should be focused on to ensure that the athletes win medals;3) familiarity with the venues should be utilized to enhance athletes' performance;4) support of the home audience should be accommodated to bring out the best performance of athletes;5) weak sport disciplines should be strengthened to show the spirit and endeavor of the host-country athletes.
