Abstract: After World WarⅡ, electronic commerce has been greatly developed with the increasing improvement of the technology of electronic communication, which causes all-round challenges to the legal system of contracts, such as the form, electronic authentication, formation, honoring and electronic payment of contracts. As to the formation of contracts, there have already been two main different systems: the principle of sending and the principle of receipt, but electronic commerce has enormously reduced such differences and combined them to some degree. This paper makes an approach to the effects of electronic commerce on the formation of contracts.
