Consumers the right to withdraw, is refers to the consumers in the business contract must special within the time limit can be wise to consider itself concluded about whether he is really worth, and no preconditions to eliminate the power of the contract. Consumers to withdraw in rail system was set so that consumers have the opportunity to itself takes action to stop the perceptual re thinking, the performance of the credit consumer rights and interests of the cover of the tilt, the rail system consistent with ancient legislation growth trend, can perhaps make the magistrates courts and arbitrators pressure to increase, so that consumers do not have to worry about, Ning God the eve of the biliary bravely to stop spending movement. Follow the ceaseless development of economy and society and consumers to withdraw in rail system in many developed countries have been established and increasingly perfect. In China in 2014 March 15, announced the new revision of the "cost of Equity Protection Act" and the revision to break the contract and strict adherence to the principle, entered into contract on both sides to the commodity information control of unfair, contract both parties completed the real position of, the real implement the nature of the contract freedom principle. However, the newly revised "spend 'rights and interests protection law" on consumers to withdraw the delineation of right is not enough to improve and perfect, there are still such as the object of the standard is not comprehensive, not the returned goods is not clear, defined starting moment, and the seller told, don't understand, return cost bear the main achievement, was the return of goods of "missing" scale not detailed results. Through against consumers to withdraw the right track of the evolution, relevant theoretical research that consumers to withdraw legislative reasons summary takes action in the presence of the following results: monopoly situation, non perceptual actions, information PI paradox says. The existence of more than to spend the three important results can perhaps significant anomalies in some particular business type or business method expressed, such as toll collection shopping, TV shopping perhaps the door dumping sales situation. In order to avoid consumers in these new cost approach emerging means than intuitive personally review goods, sales personnel on-site pressure under the purchase of goods and can not complete the know the examination in favor of the emergence of thinking results, to spend a can be calm and thoughtful itself in this case concluded contract can is entered into the time, consumers to withdraw in rail system is the request and the emergence of. Axiom of understand in spending from the above three results, we can make the following inferences: first, in the situation to make the cost action subject is a non emotional person, he is influenced by a lot of restrictions on the identity of not complete customer indecent calm resolution; second, make the cost of action is a business contract in a dominant action, relative to the operator, he of commodity information control is not comprehensive, the contract is not in place, and at the conclusion of the contract under pressure; the third, consumers to exercise the power to withdraw is a contract, the contract outwardly appear to conform to the situation, but often do not essential axioms. These three interrelated and mutually influence each other. Through the above process can be seen in the nature of contract axiom, consumer sovereignty and judicial paternalism three might in fact sufficient proof consumers right of withdrawal system. At the same time, through the cost benefit analysis process of the system can also be seen that the existence of the justice system. Through the process analysis, cost benefit, can be seen in order to make the consumers can make better choices, we should arrive at what level on the implementation of consumer protection measures; on the other hand, can be obtained through the system design process can be reasonable system of minimizing the negative effects brought by their own conclusions, at the same time. This paper analyzes the consumer with right of withdrawal system of economy, that consumers to exercise the right of withdrawal of capital in a certain extent can be very good to stop the master, it will have a negative effect on the existence and use of will, but this is not enough to affect consumers' right of withdrawal system, and along with the social economy growth, no reason to return the system is used on a global scale have become more common, but also a positive reaction occurred in the return to spend the extra cost case is shipped The operator can suffer. This paper against consumers withdraw right model legislation to stop the list analysis, German civil code has set a relatively complete consumers to withdraw in rail system, the United States in the last century also set a and consumers to withdraw in rail of the absolute cooling off period rail system and British consumers can through the exercise of contract cancellation rights, will own the purchase meaning of the commodity to be withdrawn. These developed countries about the consumer right of withdrawal system of legislative experience about the perfect legal system in China Consumers' right of withdrawal has positive enlightenment effect. In our country consumer withdrawn in the application process of the need to perfect the detailed results, important is put forward following suggestions: standard object is not comprehensive, not the returned goods is not clear, defined starting moment, and the seller told, don't understand, return cost bear the main achievement, was the return of goods "missing" scale not detailed results. In order to better solution to a consumer right of withdrawal emerge in the use of modern social life of the various grades may, this paper on how to perfect the consumer rights and interests protection law "to delineate the proposed extended object size, limit the commodity value, and the restriction of operators told responsibility, Bai Ming right exercise method, designated to exercise the power of judicial consequences, understand the abuse of rights to stop, that operators of proof obligations such as perfect view.
