Abstract: The relationship between national identity and political legitimacy is mutual proof and support. The national identity is recognized by its nationals because the national political system is reasonable and legitimate. The state also proves and enhances its legitimacy with the approval and support of its people. In the process of building a multiethnic country, national identity promotes the integration of domestic politics and society. We must resolve differences and conflicts, guide the correct orientation of ethnic, regional and religious levels, and harmonize the ethnic relations within multiethnic countries. These reflect national identity as the important force and order logic of national political construction, social stability and national unity.

Key words: national identity , political legitimacy , “integration&rdquo, and “guidance” , order logic

摘要： 国家认同与政治合法性呈一种互证互进关系，国民因为国家政治系统合理合法而认同国家实体，国家也以国民之认同和支持来证明并增进其合法性。在多民族国家建设过程中，国家认同促进国内政治、社会的一体整合，消解分歧与冲突，引导对民族、地域、宗教等次层级认同的正确方向，调和多民族国家内部的民族关系，体现出国家认同作为国民政治屋顶建构和社会稳定、民族团结的重要力量与秩序逻辑。
