摘要： 婚姻法《解释三》第5条、第10条对困扰司法实务多年的夫妻个人财产的婚后增值归属问题作了规定。虽然第5条存在比较法的误会，不足为训，但第10条却蕴含增值归属的一般规则，可以解决按揭房屋增值归属等众多实务难题。在现行法上，基于婚姻命运共同体理念，我国的婚后所得共同制应理解为“婚后劳动和运气所得共同制”，夫妻个人财产的婚后增值应一律为夫妻共同财产。《解释三》第5条、第10条在立法论上应予废除，在解释论上应予架空或重新解释。

Abstract: In recent years，Chinese courts have been constantly stormed by various issues on the classification ofthe appreciation of separate property during marriage. The Judicial Interpretation III on Marriage Law（Interpretation III） of 2011 borrowed the idea of active and passive appreciation from the U. S. marriage law ingeneral（Art. 5），and developed a rule similar to In re Marriage of Moore，28 Cal. 3d 366（1980） in particular（Art. 10）．This paper explores this classification issue from two perspectives：under the Interpretation III and under the Marriage Law. Under the Interpretation III，this paper develops a general rule similarto，but much broader than Art. 10 and applies it to solve many troublesome classification issues in practice. Under the Marriage Law，this paper sheds light on the grave deviation of all aforementioned rules in theInterpretation III from the current law and argues for an alternative solution，that the appreciation of separateproperty during marriage should be classified as marital.
