乾嘉學者的歷史評論在以實為據的前提下，有極大突破。他們不僅從古史源頭出發，進行細緻地考證、校勘，恢復史書面目，並在這樣的基礎上，把論史與考史相結合，發表自己的歷史評論。這種本末兼察、鉅細畢究的功夫，以及把史考與史論結合的歷史評價原則，正是他們能有極高治學成果之處。在求真求實的原則下，他們對《三國志》的內容、體例以及史法等，提出了不少超越前人的見解，為《三國志》研究做出重大貢獻。儘管乾嘉學者在評價人物、評論史學也有美中不足之處，不論是先入為主的尊蜀抑曹，或純以道德、正統觀論人、評事，還是歸納史料不足造成論事有缺，但透過他們的研究，都讓我們對三國史有更正確的了解，也讓《三國志》研究具有深厚的學術基礎，這都是無可抹滅的。
