Abstract: With the deepening of globalization, the boundary of national identity is no longer a single one. The boundary of national identity can be divided into natural geographical boundary, political legal boundary and historical cultural boundary. The boundary of natural geography is clear and accurate. The boundary of political law is independent and complete. we should adopt different understanding and coping strategies to the different boundary of national identity. Clear geographical boundaries should stick to. Flexible political and legal boundaries should be adjusted. Fuzzy historical and cultural boundaries should be accepted. It is of great significance to recognize and distinguish the different types of national identity.

Key words: national identity , national boundary , globalization

摘要： 全球化程度日益加深，国家认同的边界不再单一。国家认同的边界可分为自然地理边界、政治法律边界和历史文化边界。自然地理边界强调清晰、准确，政治法律边界强调独立、完整，历史文化边界强调包容、融合。国家认同三种边界的功能与相互关系是：自然地理边界承载历史文化边界，传续政治法律边界；政治法律边界确认自然地理边界，保护历史文化边界；历史文化边界宣示自然地理边界，巩固政治法律边界。对于不同的国家认同边界应当采取不同的认识与应对策略：清晰的自然地理边界应当坚守，灵活的政治法律边界应当调整，模糊的历史文化边界应当接纳。承认并区分国家认同存在不同类型的边界具有重要意义。
