📚 The State: Nation States and National Sovereignty | 国家：民族国家与国家主权
The state, the nation and sovereignty are foundational concepts in A-Level Politics. Understanding how they differ and how they interact is essential for analysing modern government, international relations and debates such as Brexit, globalisation and devolution.
国家、民族与主权是 A-Level 政治学中的基础概念。理解它们的区别与互动，对于分析现代政府、国际关系以及脱欧、全球化和权力下放等议题至关重要。
1. What is the State? | 什么是国家？
A state is a political and legal entity that has a permanent population, a defined territory, a government, and the capacity to enter into relations with other states. The 1933 Montevideo Convention sets out these four criteria, which are still widely used in international law.
国家是一个政治与法律实体，拥有常住人口、确定的领土、政府以及与其他国家建立关系的能力。1933 年《蒙得维的亚公约》提出了这四项标准，至今仍在国际法中被广泛采用。
The state is not the same as the government. The government is the group of people who temporarily run the state, while the state is the permanent institutional structure that persists even when governments change.
国家与政府并不相同。政府是暂时管理国家的一群人，而国家是持久的制度结构，即使政府更迭，国家仍然存在。
2. Key Features of a Modern State | 现代国家的主要特征
Modern states are normally expected to possess a defined territory with recognised borders, a permanent population, an effective government, and sovereignty. In addition, they usually seek international recognition from other states.
现代国家通常需要具备边界明确的领土、常住人口、有效政府和主权。此外，它们通常还寻求获得其他国家的国际承认。
The sociologist Max Weber famously defined the state as the institution that holds a monopoly of legitimate violence within a given territory. This means only the state can lawfully use force, such as through the police or the army.
社会学家马克斯·韦伯曾著名地将国家定义为在特定领土内拥有合法暴力垄断权的机构。这意味着只有国家才能合法使用武力，例如通过警察或军队。
3. The Nation and the Nation State | 民族与民族国家
A nation is a group of people who share a common identity based on culture, language, history, ethnicity or political aspirations. Unlike a state, a nation does not necessarily have a government or sovereign territory.
民族是基于文化、语言、历史、族裔或政治愿望而具有共同认同感的一群人。与国家不同，民族不一定拥有政府或主权领土。
A nation state is the idea that the boundaries of a state should match the boundaries of a single nation. In practice, very few states are perfect nation states. France, Japan and Iceland are often cited as relatively close examples, while the United Kingdom is a multinational state containing English, Scottish, Welsh and Northern Irish nations.
民族国家是主张国家边界应与单一民族边界相重合的理念。实际上，很少有国家是完美的民族国家。法国、日本和冰岛常被认为是较接近的例子，而英国则是一个包含英格兰、苏格兰、威尔士和北爱尔兰多个民族的多民族国家。
4. National Sovereignty | 国家主权
National sovereignty is the principle that the state has supreme authority within its own territory and is not subject to any higher external power. It is often described as the defining feature of a state.
国家主权是指国家在其自身领土内拥有最高权力，不服从任何更高的外部权力的原则。它常被描述为国家的决定性特征。
The concept can be traced back to early modern thinkers such as Jean Bodin and Thomas Hobbes, who argued that a sovereign authority was necessary to maintain order and security. Today sovereignty has both legal and political dimensions.
这一概念可追溯到让·博丹和托马斯·霍布斯等近代早期思想家，他们认为主权权威对于维持秩序与安全是必要的。今天，主权既有法律维度，也有政治维度。
5. Internal and External Sovereignty | 对内主权与对外主权
Internal sovereignty refers to the state’s supreme law-making authority within its borders. It means the state can pass and enforce laws over all individuals and groups inside its territory without interference from other states.
对内主权指国家在其边界内拥有最高立法权威。它意味着国家可以在其领土内对所有个人和团体制定和执行法律，而不受其他国家的干涉。
External sovereignty refers to the state’s independence and equality in the international system. It means other states recognise its right to govern itself and do not intervene in its domestic affairs. Both dimensions are essential, but they can come into tension when international pressures challenge internal decisions.
对外主权指国家在国际体系中的独立与平等。它意味着其他国家承认其自治权，不干预其国内事务。这两个维度都至关重要，但当国际压力冲击国内决策时，它们可能产生张力。
6. Legal and Political Sovereignty | 法律主权与政治主权
Legal sovereignty identifies the body or person that has the ultimate legal authority to make laws. In the UK, legal sovereignty is traditionally located in Parliament, a principle known as parliamentary sovereignty.
法律主权指拥有最终立法权威的机构或个人。在英国，法律主权传统上属于议会，这一原则被称为议会主权。
Political sovereignty refers to where real power ultimately lies in practice. In a democracy, the people or the electorate are often seen as politically sovereign because governments derive their authority from the consent of the governed.
政治主权指实际权力最终掌握在何处。在民主国家，人民或选民常被视为拥有政治主权，因为政府的权威来自被统治者的同意。
Popular sovereignty is the idea that legitimate authority comes from the people. It was central to thinkers such as John Locke and is reflected in democratic elections and referendums.
人民主权是指合法权威来自人民的理念。它是约翰·洛克等思想家的核心观点，并体现在民主选举和全民公投中。
7. Pooled Sovereignty and the European Union | 共享主权与欧盟
Pooled sovereignty occurs when states voluntarily agree to share decision-making power in certain policy areas with supranational institutions. This does not mean sovereignty is lost; rather, it is exercised collectively to achieve shared goals.
共享主权是指各国自愿同意在某些政策领域与超国家机构共同行使决策权。这并不意味着主权丧失，而是为了共同目标而集体行使主权。
The European Union is a leading example. Member states have pooled sovereignty in areas such as trade, competition, agriculture and some aspects of justice and home affairs. EU law can take precedence over national law in these areas, which has caused intense debate about national sovereignty.
欧盟是一个典型例子。成员国在贸易、竞争、农业以及司法与内政的某些方面共享了主权。在这些领域，欧盟法律可优先于国内法，这引发了关于国家主权的激烈辩论。
8. Globalisation and Challenges to National Sovereignty | 全球化与国家主权面临的挑战
Globalisation has increased economic, cultural and political interconnectedness, which can limit the ability of nation states to act independently. Multinational corporations, global financial markets and international supply chains often operate beyond the control of any single government.
全球化加深了经济、文化和政治的相互联系，这可能限制民族国家独立行动的能力。跨国公司、全球金融市场和国际供应链往往超出任何单一政府的控制范围。
International law, human rights treaties and organisations such as the United Nations also place moral and legal pressures on states. However, states remain the central actors in global politics because they still control borders, laws, taxation and the legitimate use of force.
国际法、人权条约以及联合国等组织也对国家施加道德和法律压力。然而，国家仍是全球政治的核心行为体，因为它们仍然控制着边界、法律、税收和合法使用武力的权力。
9. Sub-State Nationalism and Devolution | 次国家民族主义与权力下放
Within many states, sub-state nationalism challenges the idea of a unified nation state. In the UK, Scotland, Wales and Northern Ireland have nationalist movements that seek greater self-government or independence.
在许多国家内部，次国家民族主义挑战着统一民族国家的理念。在英国，苏格兰、威尔士和北爱尔兰存在寻求更大自治或独立的民族主义运动。
Devolution transfers certain legislative and executive powers from central government to regional bodies, such as the Scottish Parliament and the Senedd Cymru. However, under the UK’s uncodified constitution, legal sovereignty remains with the Westminster Parliament, which can in theory reclaim those powers.
权力下放将某些立法和行政权力从中央政府转移给地区机构，例如苏格兰议会和威尔士议会。然而，在英国不成立宪法下，法律主权仍属于威斯敏斯特议会，理论上它可以收回这些权力。
10. Conclusion: Sovereignty in a Changing World | 结论：变化世界中的主权
Sovereignty remains a central principle in A-Level Politics, but it is increasingly contested and reshaped by globalisation, supranational organisations, devolution and nationalist movements. The state has not disappeared, but its authority is now shared, pooled and negotiated more than in the past.
主权仍是 A-Level 政治学的核心原则，但它正日益受到全球化、超国家组织、权力下放和民族主义运动的挑战与重塑。国家并未消失，但其权威比过去更多地被分享、集中和协商。
For exam success, be ready to define key terms precisely, use contemporary examples such as Brexit and the Scottish independence debate, and discuss both sides of the sovereignty debate.
为了在考试中取得好成绩，请准备好准确界定关键术语，运用脱欧和苏格兰独立辩论等当代案例，并讨论主权争论的正反两面。
