《长短经》是唐代学者赵蕤编写的一本纵横学著作。共九卷64篇，集儒家、道家、法家、兵家、杂家和阴阳家思想之大成，黑白杂糅之书，深入地剖析君臣谋略的利害得失，不失为官场学扬名立万的顶级范本。成书后作者亦因此显名于世，时人称“赵蕤术数，李白文章”。全书整体框架以谋略为经，历史为纬，交错纵横，蔚然成章。作者打破时空界限，从宏观上鸟瞰了上至尧舜、下至隋唐的历史全貌，围绕权谋政变和知人善任这两个重心，时而引经据典，雄辩滔滔；时而运筹帷幄，驰骋沙场；时而审时度势，策划于密室；时而纵横捭阖，游说于诸侯。既有五侯争霸的刀光剑影、百子争锋，又有三国割据的金戈铁马、斗智斗勇。奇谋叠出，电击雷鸣。铺述历史，或则白描淡线，或则浓墨重彩。有理论上的探讨，有策略上的权衡，有人物的品评，有得失的反思。因此可以说，《长短经》既是对唐以前历史的多角度、全方位的审视，也是历代政治创意与谋略之集大成。 （ The book is a famous work of vertical and horizontal theory compiled by scholar of Tang Dynasty Zhao Rui.
