【摘要】 全面抗战初期，“统一战线”接续“联合战线”一词，成为推动团结抗战的普遍表达。然而，因国共双方未能就合作机制达成一致，“统一战线”具体内涵仍有诸多含混之处，以致在具体实践中难以把握分寸。与此同时，这一概念成为多方共享的政治资源，并广泛介入现实，国民党亦曾试图争取对“统一战线”的主导权。对中共而言，围绕统一战线的阐释工作既要加强规范，以确保各地贯彻落实协调一致；还应丰富其内涵，以应对可能出现的摩擦与冲突。作为具有强烈现实指向性的政治概念，“统一战线”在实践中经历了反复的检验与调整，最终得以在复杂的政治博弈和不断变化的局势中逐步明晰其内涵，发展为稳定的政策理论，沉淀为中共的重要理论资源。更多还原

【Abstract】 In the early stages of the comprehensive Anti-Japanese War, the term "united front" replaced the term "alliance front" and became the widely adopted expression for promoting unity in the resistance against Japan. However, due to the failure of the Kuomintang and the CPC to reach an agreement on the cooperation mechanisms, there were still many ambiguities in the specific connotation of the "united front", making it difficult to grasp the appropriate balance in practical application. Meanwhile, this concept became a shared political resource among multiple parties and widely intervened in reality. The Kuomintang also attempted to gain dominance over the "united front". For the CPC, the interpretation of the "united front" should not only strengthen norms to ensure consistent implementation across regions, but also enrich its connotations to address potential frictions and conflicts.As a political concept with strong practical orientation, the "united front" underwent repeated testing and adjustment in practice, gradually clarifying its meaning through complex political struggles and ever-changing circumstances. Ultimately, it evolved into a more stable policy theory, and precipitated as an important theoretical resource of the CPC.更多还原
