从"抽象到具体"的叙述方法与从"具体到抽象"的研究方法是《资本论》的基本方法论。"价值形式"一节集中展示了这一辩证的方法论，叙述方法遵守着形式（抽象）的结构与内容（质料）世界的同一性原则和形式（抽象）的结构与内容（质料）世界的同步发展、完全平行的原则，并且形式成为了质料追求的一个目的。这样一种叙述方式成为了当今马克思哲学研究中流行的研究方法，这是对《资本论》方法论的错用。研究方法要求的是对"既定主体内容"的研究，在马克思那里则体现为对作为内容的资本主义社会经济结构的批判。重新展开对这一错用的反思，才能切实推进解放理念的建构。

The narrative method "from abstract to concrete" and the research method "from concrete to abstract" constitute basic methodology in Das Kapital,which has been well-demonstrated in the section "Value Form". As for the narrative method,it abides by the principle of identity between(abstract)form structure and (material)content world and the principle of their synchronous development and complete parallelism so that form is an end of material pursuit. Such a narrative method has become a popular research method in today's study of Marxist philosophy. This is a misuse of the methodology of Das Kapital. The research method requires to study the "established subject",which is embodied in Marx's criticism of the economic structure of capitalist society as the content. Only by reflecting on this misuse can we effectively promote the construction of the concept of emancipation.
