李斯 〈諫逐客書〉通篇精辟磅礡、詞采鋪張揚厲，為古代法家少有華辭之作與上書之善。然而在有關秦國西并巴蜀之事上，〈諫逐客書〉張儀西并巴蜀之說則頗有進一步商榷之處。此外，其背後更潛隱著秦國「本土派」人才與「外來派」客卿之間的論爭。全文凡四章。首章為本文問題的產生。次章為〈諫逐客書〉援引張儀西并巴蜀之商榷。從歷史考證的角度切入，還原秦國西并深耕巴蜀應為司馬錯之倡議；且司馬錯亦為秦人，非李斯所云外來客卿。第三章則為〈諫逐客書〉援引張儀西并巴蜀之疑議。主要探討李斯〈諫逐客書〉援引張儀西并巴蜀之心理分析，並從秦國西并巴蜀相關史事記載中稽鉤史公著史之客觀嚴謹精神。除此之外，並以之分析秦國「本土派」人才與「外來派」客卿之競爭。最後為結語。〈諫逐客書〉雖然充滿雄暢的論辯語言特色，但在司馬遷客觀、嚴謹的著史精神下，仍保留秦國外來客卿與本上宗室人才最終競爭、秦王外來客卿與本土宗族三者微妙平衡的互動等發展現象。就秦國發展史而言，有其重要的貢獻。
