在台灣，有不少先人先後參與各類的左翼運動，其中林日高也是其中一員且他也是台灣共產黨創立成員之一，雖然他參與台灣共產黨只有兩年，但這也並無減損其在左翼運動的貢獻，然而遺憾的是林日高本人也未留下著作，而在之後的二二八事件中雖非要角且逃過一劫，但後來卻因過去的台共經歷，導致日後被政府羅織加入民主革命聯盟並吸收青年，最後被判處死刑。然而與林日高有關的研究中大多是以事件或組織為主。而本篇論文便試圖藉由現存的資料與研究，來撰寫林日高其一生大致上的脈絡與事跡。
In Taiwan, many ancestors have participated in various left-wing movements. Among them, Lin Jih-kao is also one of them and he is also one of the founding members of the Taiwan Communist Party. Although he has only participated in the Taiwan Communist Party for two years, this does not detract from his status. The contribution of the left-wing movement, however, it is regrettable that Lin Jih-kao himself did not leave a book. Although he was not a major player and escaped in the subsequent February 28th Incident, his past experience of the Taiwan Communist Party led to the future Fabricated by the government to join the Democratic Revolutionary League and recruit young people, he was finally sentenced to death. However, most of the research related to Lin Jih-kao is based on events or organizations. This thesis attempts to compose the general context and deeds of Lin Jih-kao's life based on existing data and research.
