本文採用歷史與文獻分析法，探討總體戰爭時期與冷戰時期的宣傳戰，闡述戰爭不僅是軍事武力的鬥爭，還有一個影響輿論的宣傳戰場，而輿論力量的主動權正是掌握在政府與軍隊手中。本研究指出，新傳播科技不斷向前進展，卻也迅速的轉為人類戰爭中凝聚向心及克敵制勝的武器。但構成宣傳戰的要素不止一端，從一戰及二戰的英、美、德國、冷戰時期的意識形態之爭及韓戰、越戰的例子，可見不可或缺的條件還有政府與軍隊如何運用當時的傳播科技、有效的宣傳機制及宣傳作為去整合、發揮與調控。

This study conducted by history and literature analysis explores propaganda battle during the periods of Total War and Cold War, and elaborates that beyond battle force, propaganda battle is another power to sway public opinion, of which the initiative is taken by government and military force.The findings indicate that cutting-edge technology in communication makes incessant progress, but is swiftly adopted as a weapon of cohesion and triumph. However, propaganda battle is no less than one element. It also requires the way of current communication technology application, and efficient propaganda and operation in terms of integration, development, and control. This is obviously reflected in Korean War, Vietnam War, ideology dominance in Cold War, and the contention among Britain, America, and Germany in two World Wars.
