本文欲刻劃左翼精神和現代主義，如何在陳映真小說從合流變成分流的軌跡。其早期小說和魯迅相似的題材類型都可用現代主義承載理想，但隨著美援而來的經濟殖民以及七○年代鄉土文學論戰，外緣因素交相影響使然，改變陳映真對於文學的思考，進而改變文學策略。討論脈絡為：早期現代主義小說中左翼的模糊面貌，到「文學季刊」時期（1966-1978）開始揚棄現代主義，另一方面，左翼精神面貌漸趨清楚，再加以時代外緣因素討論，由此解釋，他為何揀取現實主義作為後期創作風格之因。當文學成為表述理想的方式時，文學技巧和書寫策略都成為表達理想的介質，技藝會隨著理想的改變而變遷。否定現代主義就是揚棄過去創作主要技巧的同時，陳映真必須重新塑造小說的書寫策略。確定選取現實主義技巧書寫後，他加強了民族主義的思想，講述他對於臺灣當代社會的批判性。本文將描繪陳映真風格轉向變遷軌跡，探究其變遷背後之因素。

This paper intends to describe why and how Chen Ying-Zhen's trajectory of left-wing spirits alienated from his early modernist style. Similar to some of Lu Xun's certain writing, Chen took the stance of a modernist and considered modernism as a media to convey his ideals in his earlier works. Yet after the economic colonization came along with the American Adds and also after the Native Literary Debate, these historical events had influenced his writing style and his writing strategy thus had been altered. What this paper tries to discuss is to delineate the shifting in Chen Ying-Zhen's styles. In his early writings, Chen deploys modernism unconsciously. As time goes by, especially during the Literature Quarterly period, he alienated himself from modernism. His left-wing spirit becomes clearer and there are more ideological elements in his works. The aims of this paper is to depict how Chen turned to realism in his later style in accordance with the exterior events. As writing strategy and literary skills only serve as the vehicle to convey his ideology, they are constantly changing with the shifting trajectory of Chen's ideology. It is necessary for Chen to reconstruct a new writing style if he tries to abandon his early modernist image. After revising his version of realism, he applies this updated realism to criticize contemporary Taiwan society with his nationalistic point of view. In this paper, I would like to trace the trajectory of Chen's stylistic turn in his texts and illustrate the reasons behind it.
