唐《五經正義》之撰成實集多人之力，但相關編修者卻因史料缺乏，而未能得到相應之研究。有鑒於此，此文擇定參與編修之名儒馬嘉運為對象，並分兩個方向進行探討。首先依兩《唐書》、《冥報記》及相關資料綜合判斷，釐清馬嘉運生平大致經歷。接著，探討馬嘉運與《五經正義》的關係，辨析他對於孔穎達駁正批評的時間點，以其他對《五經正義》的影響。藉由此文研究成果，對於貞觀16年時《五經正義》編修過程當可有更進一步理解，並對唐初經學史之認識有所裨助。

Many scholars and editors contributed to the project of the ”Explanatory Notes to the Five Classics” in Tang Dynasty. The studies on the scholars and editors are however relatively scarce, because little historical records on them are available. To bridge the gap, this paper aims to look into the life of Ma Chia-Yun, one of the famous scholars who participated in the project, so as to provide a clearer picture of the Confucian studies in the beginning of Tang Dynasty. Firstly, certain historical records are drawn from ”New Book of Tang” (”Shin Tang Shu”) and ”Book of Tang” (”Joe Tang Shu”) and ”Retribution after Death” (”Ming Bao Gee”) in order to piece together the life experiences of Ma Chia-Yun. Secondly, the time point where he critiqued Kong Yin-Da and his impact on the studies of the ”Explanatory Notes to the Five Classics” are also examined. The result of the above studies would shed more light on the editing process of ”Explanatory Notes to the Five Classics” in the 16th year of Zhenguan period and the history of the study of Confucian classics in Tang Dynasty.
