摘要： “家庭共同体”价值与“个人意志”价值是夫妻财产法中的基本矛盾，在我国法上的制度反映是法定财产制与约定财产制的架构关系。《婚姻法》现有规定将约定财产制边缘化。家庭财产、离婚率和“少子化”等时代变化引发了夫妻财产法价值本位向“个人意志”价值一端的位移，《婚姻法司法解释三》试图对此展开修正，但受到了一些质疑。法定财产制的不周延性、对不同价值诉求群体选择空间的保留、议价程序前置带来的收益，均证成了完善约定财产制的正当性。完善约定财产制的路径包括约定财产制本身的制度细化，以及与法定财产制的联动改革。对个人本位的价值修正，与构建社会主义和谐家庭关系的目标是辩证统一的。

Abstract: “Family collectivity”value and “individual will”value constitute the basic value contradiction in the marital property law. The system reflection of the contradiction is the structural relationship between statutory property system and contractual property system. The Marriage Law has the tendency to marginalize contractual property system. The variation in family property, divorce rate and children amount have caused the value shift of marital property law, enhancing the status of “individual will” value. The Third Judicial Interpretation of Marriage Law attempted to amend this, but it was not successful. The defects of the statutory property system, the choice space for different communities, and the benefits of the pre-bargaining process all demonstrate the advantages of the contractual property system. The path of improving the contractual property system includes the elaboration of the contractual property system itself and the linkage reform of the statutory property system. The value shift of the marital property law and the goal of building a socialist harmonious family relationship constitute a dialectical unity.
