我国民事法律虽然对公序良俗原则有所规定，但是在司法机关适用该原则时仍存在“乱用”、“错用”等问题，其根源在于对公序良俗原则内涵理解不清。公序良俗原则属于民法中规定社会性内容的条款，应当受到宪法积极地调控。应当摆脱部门法内固见，从法律体系整体尤其是宪法及其规定的基本权利视角出发，对相关条文进行解释并对公序良俗原则的内涵进行分析。 传统研究中公序良俗原则被分为“公共秩序”与“善良风俗”两部分，其内涵分别被认定为“一般利益”以及“一般道德”，对内涵的细化方法主要为??出判断标准、建立适用类型以及兜底价值补充的方法。但是上述方法并未顾及宪法对于民法的影响，且自身存在适用逻辑不清、分析方法混乱等问题。 “基于宪法的解释”方法旨在通过对宪法以及部门法条文进行解释将宪法价值蕴含于 一般法律之中。应当利用该方法对公序良俗原则的内涵进行解释以解决传统研究中的问 题。我国宪法第 53 条将“公共秩序”以及“社会公德(公领域的善良风俗)”设定为公 共利益，且设定“遵守”以及“尊重”两种不同程度的保护。结合对《宪法》其他相关条 文的解释可知，公序良俗原则由具有不同宪法地位的“公共秩序原则”、“公领域善良风 俗原则”以及“私领域善良风俗原则”三部分组成。《宪法》承认公共秩序以及公领域的 善良风俗的社会价值，并建立起结合规制与促进手段的保护体系。而私领域的善良风俗虽 然不能作为公共利益，国家仍需要履行宣传、推广的促进义务。 在此基础上，可以构建起以合宪性秩序为基础价值、适用不同判断标准的公序良俗原则内涵一般判断方法。其中，公序良俗原则各部分的领域可以通过公私法的界分确定。公共秩序原则应当在公法秩序中适用国家标准并以专家标准进行判断;善良风俗原则的内容则应该在采纳国家标准的基础上结合民族标准以“一般的理智主体身份”进行判断。除此以外，公共秩序的内容还需要纳入符合合宪性秩序标准的法外公共政策，善良风俗的内容则需要区分公私领域界分以及纳入国家推广宣传的价值观。

Although China's civil law stipulates the Principle of Public Order and Good Morals, there are still problems such as "disorderly use" and "misuse", when the judicial organs make use of this Principle. This problem results from the fact of unclear understanding of the Principle’s conception. In fact, the Principle of Public Order and Good Morals belongs to the provisions of the civil law that stipulate social content, and should be directly regulated by the Constitution. Thus the stereotypes in the departmental law should be get rid of, and the Principle should be interpreted from the perspective of the legal system as a whole, especially the Constitution and the basic rights. In the traditional study, the Principle of Public Order and Good Morals is divided into two parts: “public order” and “good customs”. Their connotations are respectively identified as “general interest” and “general morality”. The methods of refinement are judgment standards, applicable types and value supplement. However, the above methods do not take into account the influence of the constitution on civil law, and there are problems such as unclear application logic and chaotic analysis methods. The “constitution-oriented interpretation(verfassungsorientierte Auslegung)” aims to embody the constitutional value in general law by interpreting the constitution and the departmental law. This method should be used to interpret the connotation of the Principle of Public Order and Good Morals to solve the traditional problems. Article 53 of Constitution sets "Public Order" and "Social Morals (Good Morals in the public domain)" as public interest, and sets two levels of protection through two different words "observe" and "respect". Combined with the interpretation of other relevant provisions of the Constitution, the Principle of Public Order and Good Morals are separated into three parts: "the Principle of Public Order", "the Principle of Good Morals in the public domain" and "the Principle of Good Morals in the private domain ", with different constitutional status. The Constitution recognizes the Public Interest of Public Order and Good Morals in the public domain, and establishes a system of protection for them that combines regulation and promotion. Although the Good Morals in the private domain cannot be regarded as a public interest, the Public Authority should still fulfill promotion obligations of propaganda and promotion. On this basis, it is possible to construct a general judgment method for the connotation of the Principle of Public Order and Good Morals based on the Constitutional Order and applying different judgment standards. Among them, the scopes of each part of the Principle of Public Order and Good Morals can be determined by the distinction between public and private law. Within the Principle of Public Order, in addition to applying national standards and expert standards, extra-legal public policies are also necessary to consider; The Principle of Good Morals should be affirmed with not only national standards and "General Rational Subject" standards, but also nation’s standards. Besides, the content of the Principle of Public Order is supposed to include extrajudicial public policies that conform to the standards of Constitutional Order, while the content of Good Morals needs to distinguish between the public and private domains and take the national culture propaganda into account.
