自1990年代初期開始，學術界對良渚文化年代的推訂出現分歧，目前尚未達成共識。本文著重對欒豐實論證良渚文化年代的方法、材料進行討論，不贊成「良渚文化的絕對年代約在西元前3500-前2500年之間」的結論。對良渚文化(除崧澤—良渚過渡段)的開始年代保留原有推訂，即距今5200年前後。新發現的廣富林遺存晚于良渚文化，其年代是探討良渚文化結束年代的關鍵節點。

The early 1990s witnessed the emergence of disagreements within the scholarly community concerning the periodization of the Liang-chu culture. The debate has yet to be resolved. The present essay discusses the methods and evidence used by Luan Feng-shih to periodize the Liang-chu culture, and does not support the conclusion that “the absolute period of the Liang-chu culture falls approximately between 3500 and 2500 B.C.” The author favors maintaining the original date of ca. 3200 B.C. as the beginning of the “Liang-chu Transitional Period.” The recent discoveries at Kuang-fu-lin postdate the Liang-chu culture, and their chronology is a key piece of evidence for dating its termination.
