摘要： 在我国民法上，标的物所有权的移转虽以交付或者登记为要件，但合同法关于买卖合同的规定即足以表明买卖合同不仅具有发生债权债务关系的效力，也具有引起所有权发生移转的效力，故我国民法存在不承认物权行为独立性的依据。在不能废除无权处分规则的背景下，可以将无权处分所订立的合同理解为合同的权利移转效力待定，但其履行效力则不受影响，因而在当事人违反合同约定的给付义务时，应承担违约责任。为回应现代交易的复杂性和阶段化，要么将法律行为区分物权行为与债权行为，要么对合同效力作不同层次的理解。在中国法的语境下，以后者作为法释\[2012\]8号第3条的理论基础，也许是一种可供选择的思维路径。

Abstract: In the Chinese civil law，although the delivery or registration is necessary for the transfer of ownership，the rules of the sales contract in the Chinese Contract Law sufficiently indicate that sales contract not only hasthe effectiveness to result in debtor-creditor relationship between the parties，but also has the effectiveness tolead to the transfer of the ownership. So there are evidences to derecognize the independence of PropertyAction in Chinese civil law. Because the rule of unauthorized disposition cannot be abolished，the ownershiptransfer effectiveness of sales contract is pending when the contract is made by the person who has not authorized disposition. But the rule of unauthorized disposition cannot make any impact on the effectiveness of salescontract to result in debtor-creditor relationship between the parties. In light of this theory，if any party violates the contract，he should burden the responsibility for breach of the contract. In response to the complexity and staging of modern transaction，either the transaction should be distinguished between Property Actionand Obligation Action，or the effectiveness of contract should be distinguished to different levels. Under thecontext of Chinese law，maybe there are alternative approaches to understand the unauthorized dispositionrule，which is the theoretical basis of Article 3 of the judicial interpretation No.［2012]8.
