This thesis analyzes the status quo and the major channels of Chinese children’s participation in political affairs in various perspectives such as forming association，participating in legislation，offering advice and suggestions，expressing opinions，etc. In terms of legislation，children’s participation is mostly in the form of providing information，i.e. providing information for government decision makers，indirect participation in legislation and policy consultation. Children joining the Young Pioneer and juveniles joining the Youth League are their common ways of participation in political association. Through the association of joining the Young Pioneers and electing representatives attending China Young Pioneers’ Conference and many other activities，Chinese children are indirectly involved in the formulation and execution of the relevant policies and in the evaluation of results，thus realizing the practice of participating in the administration and discussion of state affairs. Young Pioneers Conference and Red Cravat Institution are the major channels for Chinese children to get involved in politics，and the most extensive approaches for political participation as well. In terms of offering advice and suggestions，children may express their opinions through various channels and systems such as letter and visit system，the specific websites run by governments at all levels，etc. In practice，children’s expression of advice and suggestions has received great attention，or has achieved remarkable results through practical activities，so such practices are widely promoted and spread，and thus more systems and channels are created and opened for children to express their advice and suggestions. As for sharing and expressing opinions，besides the platforms and participation events created/founded by （adults） institutes，more children tend to express their appeals and opinions through non-institutionalized means such as media network. The author suggests further improving the institutionalized channels for children’s indirect participation，expanding the institutionalized channels for their direct participation，guiding children to make wise use of the non-institutionalized channels of participation，and thus contributing to the generally healthy，positive and stable development of children’s political participation.
