本书对商鞅变法改革和《商君书》思想进行综合性研究。商鞅是战国中期法家的著名代表人物，杰出的政治家、军事家和思想家。他得到秦孝公的支持，在秦国两次变法，力主“耕战”“富国强兵”，使秦国迅速崛起，为后来的“秦王扫六合”奠定了基础。可以说，商鞅是“为秦开帝业的改革家”，其改革对后世影响深远。而现传《商君书》是商鞅及其后学撰写的著作，可视为商鞅学派的思想总集。商鞅学派虽不必为秦朝速亡直接负责，但他们专制、狭隘的功利主义文化政策和对精神文明、伦理道德的忽视，亦是秦亡的原因之一。本书结合商鞅变法史实与典籍思想，不仅细致勾勒出商鞅学派的思想内容，深刻指出商鞅变法的历史意义，同时彻底反思了商鞅学派与秦二世而亡的关联，具有重要的学术价值。

This book is a comprehensive study of the reform of the Shang Martingale Law and the thought of the Shang Junshu. Shang Martingale was a famous representative of the Legalists in the middle of the Warring States period, an outstanding politician, military strategist and thinker. He received the support of Qin Xiaogong, and changed the law twice in the Qin state, advocating "cultivation and war" and "rich country and strong army", so that the Qin state rose rapidly and laid the foundation for the later "King of Qin sweeping the liuhe". It can be said that Shang Martingale was "a reformer who opened the imperial industry for Qin", and his reforms had a far-reaching impact on future generations. The current "Book of Shang Jun" is a work written by Shang Martingale and his successors, and can be regarded as a collection of ideas of the Shang Martingale school. Although the Shang Martingale school was not directly responsible for the rapid demise of the Qin Dynasty, their authoritarian and narrow utilitarian cultural policy and neglect of spiritual civilization and ethics were also one of the reasons for the Qin dynasty. This book combines the historical facts and classic ideas of the Shang Martingale Transformation Law, not only meticulously outlines the ideological content of the Shang Martingale School, profoundly points out the historical significance of the Shang Martingale Transformation Method, but also thoroughly reflects on the relationship between the Shang Martingale School and the death of Qin II, which has important academic value.（AI翻译）
