Research On The Distribution Characteristics Of Competition Events In My Country's 29th-31st Summer Olympic Games From The Perspective Of Comparative Advantage Theory

In the last three Olympic Games,the number of gold medals and medals of the Chinese delegation has been decreasing.The ranking of medals has fallen from first place to third place.Under the background of the upcoming holding of the 2020 Tokyo Olympic Games,the level of competitive sports in various countries around the world is constantly improving.The Chinese delegation faces serious challenge.Therefore,it is urgent to analyze the development of Olympic events.From the perspective of comparative advantage theory,this paper divides 29-31 Summer Olympic Games competition projects into the comparative advantage project group,the comparative advantage project group and the relatively disadvantaged project group according to the comparative advantage index of each project.The project group is unit.The paper analyzes the project composition of the three major project groups,Xiangqun's ownership,geography,age,gender distribution,etc.By means of literature,mathematical statistics,logic analysis,and Palato method,and puts forward the development countermeasures of the Olympic Games competition project in China.The aim is to provide reference for the sustainable development of our Olympic project.The results show that:1.In terms of the project composition,the number of the comparative advantage project groups in China is relatively stable,and the population of the sub-potential project has a decreasing trend.The population of the disadvantaged groups is compared with the increasing trend.The items of the three-year comparative advantage item group are table tennis,badminton,gymnastics,swimming,shooting,boxing,weight lifting,and the items of the group with the potential advantages are the bicycle,the track and field,the wrestling,the rowing boat,the judo,the fencing and the sailing boat;The project of comparing the vulnerable groups is three,equestrian,basketball,football,and handball.2.In term of that ownership of the item group,the group of comparative advantage item group belong to a strong overall stability,the distribution range of the item group is wide,the dynamic change is not obvious,and the skill-dominated large item occupies an absolute advantage,There is a slight reduction in the home range of the item group,the group belonging to the potential advantage is relatively balanced in the distribution of the broad categories,but the two polarization phenomena of the sub-group distribution are obvious,the home of the item group is in a centralized trend,and the skill-leading type combat antagonistic item group has the main advantages,the home range of the group of items is distributed in the range of 5-6 sub-classes and is in a shrinking trend,The non-equilibrium situation is presented,and the distribution of subclasses is highly concentrated in the field adversarial group,and the home range of the item group is expanded.3.In terms of the geographical distribution,the geographical distribution of the comparative advantage project group has the relative stability,and the geographical distribution characteristic presents a clear distribution of the economic development direction;the regional distribution of the sub-potential advantage project group is obviously different,with the two polarization relaxation signs;and the northeast region,North China and East China are the main areas for the development of our country's more vulnerable projects.The main geographical distribution of the three major project groups is East China,Northeast China,North China,and the project distribution has obvious regional and regional distribution.4.In the aspect of age distribution,the average age of athletes in comparative advantage group was relatively young,which was concentrated between 17 and 28 years old,and the 21-24-year-old group was the most prominent,but the number of athletes in this age group showed a decreasing trend.The age of athletes in comparative potential advantage events is concentrated between 21 and 28 years old,the most prominent is 25-28 years old,and the average age of athletes is increasing constantly,the floating range of age is unstable,and it shows the distribution characteristics of "no too old,no too young";The average age of athletes in the more disadvantaged project groups is relatively large,and they are concentrated between the ages of 21-28.The difference between the ages of 21-24 and 25-28 is not significant,and the athletes 'competitive age presents a "double peak";The age dispersion of athletes in the three major project groups was gradually reduced.5.In the aspect of gender distribution,the total distribution of male and female athletes in the three categories of events presents the development trend of "Women strong and men weak".In the aspect of contribution rate,the difference of gold medal contribution rate between men and women in comparative advantage project group was narrowed,and the trend of increase and decrease of medal contribution rate was the same between men and women.In terms of the gold medal contribution rate of the comparative potential advantage group,the male athletes' anti-super trend was prominent,the male and female athletes' medal contribution rate showed the opposite distribution trend,and the male athletes' medal contribution rate decreased gradually.The contribution rate of female athletes' medals increased gradually.In terms of overall contribution rate,there is little difference in the contribution rate of gold medals between men and women.The rate of female athletes is far ahead.
