目前,理论界对于网上交易过程中的意思表示区分尚无定论。正确界定网上零售交易合同的要约、要约邀请、承诺等概念,可以解决网上零售交易合同的要约与承诺是否可以撤回、撤销,消费者单方解除权与承诺撤销权的区分等问题,因此,讨论并解决相关问题很有必要,可为构建网上交易基础理论起到抛砖引玉的作用。 At present, there is no conclusion that theorists make a distinction between the meanings of online transactions. Correctly defining the concept of offer, invitation to offer and commitment in online retail transaction contract can solve the problem of withdrawal and cancellation of the offer and commitment of online retail transaction contract, the distinction between unilateral termination rights of consumers and the right of withdrawal of commitment, and so on. Therefore, It is necessary to solve the related problems and can play a valuable role in building the basic theory of online trading.
