【摘要】 无权处分问题被法学界称为“法学上的精灵”,其曾经困扰台湾法学界五十载,经过王泽鉴先生的多次“拨乱反正”,最终将其驯服。无权处分问题至今仍困扰着我国大陆法学界,其中无权处分合同效力问题是无权处分问题的核心。我国《合同法》第51条和《买卖合同司法解释》第3条关于无权处分合同效力的问题的争论依然没有停止。为早日解决无权处分问题,必须对无权处分合同效力制度有一个合理的构建。为达到此目的,本文首先厘定无权处分的相关概念,为合理构建无权处分合同制度提供一个基本的理论支撑。厘清相关概念后,通过比较法分析的方法,着重介绍了不同物权变动模式下的无权处分合同的效力,发现是否承认物权行为理论,对于处理无权处分合同效力至关重要。国外关于无权处分问题的相关规定,可以为我国合理的解决无权处分合同效力问题提供经验和借鉴,通过比较法的分析,从外国法的视角再回到本国法,对国内的一些学说理论进行评析后,本文得出物权形式主义有因性模式方为解决无权处分合同效力问题的最佳模式。此模式承认物权行为理论,但摒弃了物权行为的无因性,将无权处分合同界定为有效。采用此模式解决无权处分合同效力问题,具有逻辑上清楚、论证上严密、法理上贯通、立法成本低的优点,其可以更好地平衡第三人与权利人之间的利益,可以与我国现行的其他民法制度相衔接,可以与现行的民法体系相融合。因此,本文得出结论：在我国采用物权形式主义有因性模式具有可行性,此模式可以成为我国解决无权处分合同效力问题的立法模式。更多还原
