Abstract: Talent identification(TI) is an important pillar to support the competitiveness of competitive sports,scientific and effective TI would produce great economic benefits and good social effects.Some limitations was existed in traditional TI methods,for example,it usually ignored the non-equilibrium of body development and individual difference,the lack of space and time consistency of capacity development,and it couldn't accurately predict the specific potential of children and adolescents.Therefore,the traditional TI usually caused the waste of human capital of athletes to some extent.The particularity of winter sports such as the large number of winter events,low popularity and high investment further highlighted the limitations of the traditional TI,the early unorganized athletes transfer was appeared under this situation.The early unorganized transfer was informal and unstructured,with no fixed plan and strict organization.The successful cases of Talent Transfer(TT) were scattered and unsustainable.British steel frame snowmobiles took the lead in the attempt of organized TT,and achieved continuous success,providing“ confidence in the path”for organized TT,and the number of countries carrying out organized TT is also increasing.However,the TT theory is still controversial on many issues such as the initial concept,research significance and the choice of athletes.There are cross project success cases in winter.Most of them are limited to the speed/endurance events which are dominated by physical ability.Winter project TT practice is entering the“fast lane”of development and the“deep water area”of theoretical innovation.In order to prepare for the 2022 Winter Olympic Games,China has carried out the winter project TT practice with the highest level,the largest scale,the widest range of selection and the most comprehensive project coverage in the world.Large scale practice will become a new opportunity to enrich and improve the TT theory.
