皖南事变后，中国共产党适时提出“办一个新的苏北”战略构想。在此时代背景下，新四军“文化人”以宣传实践参与对敌斗争和民主建设，从“做无产阶级的文化战士”到成为宣传文化干部，再通过集体行动创造“新文化”，继而成为“办一个新的苏北”的关键力量。以“新苏北”宣传文化干部为历史阐释的主体视角，透过对其个体行动和群体实践的研究，可以澄清这一历史事件的有机进程与发生逻辑。从“文化城”到“模范根据地”再到“新的民主共和国之一部分”的历史进程，实质上既是“新苏北”宣传文化干部群体参与革命实践，改造客观世界的具体写照，也是先进知识分子改造主观自我，并以群体形象将自身塑造为新民主主义运动中的一个历史性主体的双重“创造”过程。

After the Southern Anhui Incident, the Communist Party of China timely proposed the strategic concept of “establishing a new Subei” (Northern Jiangsu). In the context of this era, the “intellectuals” of the New Fourth Army participated in the struggle against the enemy and democratic construction through propaganda practices. The group went from “being cultural warriors of the proletariat” to becoming cadres of propaganda and culture, and then created a “new culture” through collective actions, and eventually became a key force in “establishing a new Subei”. Taking the cadres of propaganda and culture of “a new Subei” as the subject perspective of historical interpretation, the organic process and logical occurrence of this historical event can be clarified through examining individual actions and collective practices. The historical process from “a cultural city” to “an exemplary base area” and eventually becoming “a part of the new democratic republic” was essentially a process of the dual creation by the cadres of propaganda and culture of “a new Subei”. In this process, the cadres of propaganda and culture of “a new Subei” not only participated in revolutionary practices and transformed the objective world, but also they transformed the subjective world and eventually shaped themselves into a historical subject within the New Democratic Movement.
