With the rapid development and popularization of the network, minors' participation in online transactions shows a younger age and the consumption amount is becoming greater. Because of the virtuality of online transactions and the immature mind of minors, a large number of disputes caused by the behavior of online transactions conducted by minors are also increasing day by day. In order to solve such disputes and maintain the rights and interests of minors and the stability of online transactions, it is necessary to determine the effectiveness of the acts of minors' online transactions. However, minors are not the subject of network transactions stipulated by law, and the identification of the effectiveness of network transactions of minors itself is very difficult because of the particularity of the subject and the network environment, and the lack of complete rules of proof also leads to the relief afterwards. Therefore, it is necessary to give the minors the corresponding contracting ability in the network transaction, clarify the effectiveness of the minors in the special network transactions such as standard terms and contract fraud, and improve the proof rules in the occurrence of disputes to solve the disputes.
