臺灣文化協會與《臺灣民報》在日治時期的抗日運動中，不但因共同的理念相互結合為抗日共同體，並且共同拓展文化講演會的活動，以期為抗日運動爭取更廣大的民眾基礎力量。本文的立論要旨乃是指出，抗日運動雖然是由知識階級領導，但透過兩者共同發展的文化講演運動，不僅發展了大眾參與抗日的機會，也在民眾的積極參與中，創造了知識階級反省運動方向的空間。這就是本文所要討論的公共領域的形成過程與發展，其形成要素主要來自於文化講演會與平面媒體的傳播力量，共同塑造一個開放於外，論辯被殖民政府剝削的各種權利與民族自覺的議題。在利益與共的條件下，促成民眾對公共領域的熱情回應與集體參與，從而在一九二五至一九二六年發展出文化講演的高成長期，同時也在一九二六年發生了通霄講演事件，引發各地的抵抗聲援以及知識分子對抗日運動的重新思考。

Based on the same idea, the Taiwan Cultural Association and the Tai wan Min Bao got together during the period of Japanese rule and expanded the activities of cultural lectures to have more popular support for the anti-Japanese movement.The argument of this paper is that the cultural lectures, on the one hand, expanded the opportunity to participate in the anti-Japanese movement for ordinary people which is leaded by intellectuals, and created the spaces to reflect the direction of the movement for intellectuals who leaded the anti-Japanese movement, on the other hand.It is a process of formation and development of public sphere. The two key elements are the cultural lectures and print media. They together shaped a public forum for civil right and national self-determination. Because of the common benefit, people joined the forum aggressively. Therefore, there were lots of cultural lectures during 1925-1926, but the Tongxiao lecture event make the intellectual reconsidered the strategy of anti-Japanese movement.
