If the electronic contract litigant does not have behavior ability which the traditional contract litigant must have, his/her subject identity is still qualified for the contract when the transaction object executes the reasonable duty of care.

• 如果电子合同当事人不具备传统合同当事人反当具备的行为能力，在交易对象尽到了合理的注意义务的条件下其主体身份仍然是合格的。
