王引之的《易》學著作，今日所見以《經義述聞》卷一、卷二，保存得最為完整。卷一計有54則，討論《易經》的內容。卷二計有52則，討論《易傳》的內容。但討論《易經》時，常常引用《易傳》的內容以為佐證；討論《易傳》時，也常常引用《易經》的內容以為佐證。而其研究方法，也極為靈活，有時候以六十四卦卦爻辭互證，有時候引用《易傳》與經文互證，部分內容，也有引用漢、魏《易》注，以為論證。甚至引用群經的內容以為說解，其成效頗為顯著，開啟乾嘉學者研究《易經》的新領域。本文試圖從以下幾個角度來探討其《易》學研究的成果：一、前言。說明王引之的生平、思想淵源及其著述。二、《易》例的闡釋。三、《易》爻位、爻辭與爻象關係闡釋。四、《易》之卦象在本卦之中求。五、樸學《易》的特色。六、結論。

Till now, the unabridged Writing of Yin-Zhi, Wang is “Jing Yi Shu Wen”. In Volume I had 54 units discussing Zhou I. In Volume II had 52 units discussing I Chuan. We notice that when he argued or debated Yi Jing ,he always used I Chuan, contrariwise, that means his method is flexible and elastic, sometime using Guas and Yao to interpret, sometimes using scriptures to testify each other, sometimes using the annotation of Han-Wie’s scriptures, even citing from ancient Great canons and opening the new realm of I Hsueh in the Gan-Jia Period This article tries to investigate the achievements from several aspects: Firstly, to make a description of his carrier, thought, and writings, secondly, to give some examples, thirdly, to analysis the Yao, fourthly, to show the meaning of trigram within the trigram, fifthly, to indicate the characteristic with the comparison of Pu-Hsueh in the field of I Ching. Finally, to sum up the results ,and give the presumptive description.
