社会基本矛盾主要是生产力与生产关系之间的矛盾,经济基础与上层建筑之间虽然存在着矛盾,但不构成社会基本矛盾或基本矛盾的一部分。经济关系内的矛盾是基本的,是本质的,而上层建筑内的矛盾则是对经济基础内在矛盾的反映。经济结构内在的矛盾是本质的矛盾。经济基础与上层建筑之间的矛盾则类似于本质与现象的矛盾关系。因此,即使经济基础与上层建筑之间存在着一定的矛盾关系,它们也不会成为社会基本矛盾。

The social basic contradiction is the contradiction between productive force and productive relationship.Although there is contradiction between economic foundation and superstructure,it is not the social basic contradiction.The contradiction in economic relation is essential,while the contradiction in superstructure is the reflection to economic relation.Therefore,the relationship between economic foundation and superstructure is just like the relationship between essence and phenomenon.
