鄭樵是中國古代傑出的史學家，然而對於經學他亦有相當獨特的見解；只可惜有關經學的著作，大部分都已散佚。在宋代，多數學者都沉浸在「談道說理」之時，他卻堅持自己的研究道路，不做思想上空虛的辯論，也就是他把全副精神都專注在經典意義的追求上。鄭樵在言語之間，不時流露出對「義理」與「辭章」二派的批判之意，認為兩者皆是不務實的虛學。他以理性的態度追尋儒家經典的原義，反對漢儒對經典所作的曲解，對此他也批判昀烈。本文則從鄭樵的論《詩經》與論《春秋》的殘文中，來發掘其理性思辨下對經學產生的影響。

Zheng Qiao is a distinguished historian of ancient China. However, for classical studies he is also rather unique perspective. Unfortunately, most of his work of classical studies are not present. In the Song Dynasty, when most scholars are immersed in the " Tán dào shuō lǐ ", he insisted his own research path, would not do empty ideological debate, he is heavily focused in the classic sense of the spirit of all pursuit. Zheng Qiao when he speak, always showing the critical comments about "moral principles" and "rhetoric" two faction. He thinks that both are empty of knowledge. His search for a rational manner the original meaning of the Confucian classics, against the Han scholars misinterpret the meaning of the classical studies, which he also criticized the most intense. This article, will be from the residual of his work about Shī jīng and chūnqiū, to discover the effect of the classical studies by his rational thought.
