1. Political Power, Authority and Legitimacy | 政治权力、权威与合法性
Power is the capacity of an individual or group to influence the conduct of others, even against resistance. It can be exercised through coercion, persuasion, or the control of resources. In politics, power is rarely static – it circulates through institutions like parliaments, courts and executive offices.
权力是个人或群体影响他人行为的能力，即使遭遇反抗也能实现。权力可通过强制、说服或资源控制来行使。在政治领域，权力很少静止不变——它通过议会、法院和行政机关等机构不断流动。
Authority is power that is widely accepted as right and proper. Without authority, the mere possession of force is often unstable. The German sociologist Max Weber identified three pure types of legitimate authority: traditional (rooted in custom), charismatic (based on the leader’s personal qualities) and legal-rational (derived from established rules and procedures).
权威是被普遍认为正当、合适的权力。没有权威，单纯的武力往往是不可持续的。德国社会学家马克斯·韦伯提出了三种纯粹的合法权威类型：传统型（植根于习俗）、魅力型（建立在领袖的个人特质上）和法理型（源于既定的规则与程序）。
Legitimacy refers to the belief that a government’s rule is rightful. When legitimacy erodes, a regime may face disobedience, protest or collapse. Elections, constitutional processes and the delivery of public goods all serve as sources of legitimacy in modern states.
合法性指人们相信一个政府的统治是正当的。一旦合法性被削弱，政权便可能面临不服从、抗议甚至崩溃。选举、宪制程序和公共产品的供给都是现代国家合法性的重要来源。
2. Forms of Government | 政府形式
Governments can be classified along several axes: the number of rulers, the relationship between the executive and the legislature, and the distribution of power across territory. A monarchy vests sovereignty in a single person (a king or queen), while a republic vests it in the people and their elected representatives.
政府可以沿着若干轴线进行分类：统治者人数、行政与立法的关系，以及权力在地域上的分配。君主国将主权交予单一个人（国王或女王），而共和国则将主权交予人民及其选出的代表。
In a parliamentary system (e.g. the United Kingdom), the executive emerges from and is accountable to the legislature. In a presidential system (e.g. the United States), the executive is elected separately and enjoys a fixed term, with a clearer separation of powers. Semi-presidential systems, such as that of France, combine an elected president with a prime minister responsible to parliament.
在议会制中（如英国），行政分支产生于立法机关并向其负责。在总统制中（如美国），行政首长由单独选举产生并拥有固定任期，权力分立更为清晰。半总统制（例如法国）则兼具民选总统与对议会负责的总理。
Unitary states concentrate power at the national level, though they may delegate administrative tasks to local bodies. Federal states (e.g. Germany, India) divide sovereignty constitutionally between a central authority and regional units, each with its own independent powers.
单一制国家将权力集中于中央，尽管可能将行政任务授予地方机关。联邦制国家（如德国、印度）则在宪法上将主权划分给中央和地区单元，两者各自拥有独立的权力。
3. The Separation of Powers | 三权分立
The separation of powers is a doctrine designed to prevent tyranny by dividing government responsibility into distinct branches. Its classic formulation is found in Montesquieu’s 'The Spirit of the Laws' (1748): the legislative branch enacts laws, the executive implements them, and the judiciary interprets and applies them.
三权分立学说旨在通过将政府责任划分为不同分支来防止暴政。其经典表述出自孟德斯鸠的《论法的精神》(1748年)：立法机关制定法律，行政机关执行法律，司法机关解释并适用法律。
Checks and balances are the accompanying mechanisms that allow each branch to restrain the others. For instance, a president may veto legislation, but a legislature can override that veto; courts can strike down unconstitutional statutes, while legislatures can amend constitutions or impeach judges.
制衡是伴随而来的机制，使得每个分支都能约束其他分支。例如，总统可以否决立法，但立法机关可以推翻否决；法院可以废除违宪法律，而立法机关可以修宪或弹劾法官。
The exact distribution varies across systems. In Westminster-style parliaments, a partial fusion of executive and legislative functions occurs because ministers are drawn from the majority party in the legislature, yet judicial independence remains robust.
具体的权力分配因制度而异。在西敏制议会中，行政与立法职能存在部分融合，因为大臣来自立法机关的多数党，但司法独立仍然十分稳固。
4. The Rule of Law | 法治
The rule of law is the principle that all individuals and institutions are subject to and accountable to law that is fairly applied and enforced. A.V. Dicey’s three pillars remain influential: no one can be punished except through a breach of law; no one is above the law; and constitutional rights emerge from ordinary legal decisions, not from a single written document (in the UK context).
法治是一项原则，即所有个人与机构都服从于并受制于被公正实施和执行的法律。戴雪提出的三根支柱至今仍具影响力：未经违法不得受罚；无人凌驾于法律之上；宪法权利源自普通法院的判决，而非单一一部成文宪法（就英国语境而言）。
In practice, the rule of law requires an independent judiciary, accessible courts, clear and public laws, and protection against arbitrary detention. It underpins stable democracies by ensuring that the exercise of power is predictable, not based on the whims of rulers.
在实践中，法治需要独立的司法系统、方便的诉讼途径、明确公开的法律，以及防止任意拘押的保障。它确保权力行使具有可预测性，而非基于统治者的心血来潮，从而为稳定的民主制度奠基。
5. Political Ideologies | 政治意识形态
An ideology is a coherent set of beliefs about how society should be organised and what political goals are worth pursuing. Liberalism places individual freedom, consent and limited government at its centre. Classical liberals stress minimal state interference, whereas modern liberals accept a welfare state to enable positive freedom.
意识形态是一套关于社会应如何组织、哪些政治目标值得追求的连贯信念。自由主义以个人自由、同意和有限政府为核心。古典自由主义者强调国家最小干预，而现代自由主义者接纳福利国家以实现积极自由。
Conservatism values tradition, order and gradual change. It is sceptical of abstract blueprints and defends the authority of institutions such as the family and the church. One-nation conservatism, however, favours social reform to preserve national unity.
保守主义珍视传统、秩序与渐进变革。它怀疑抽象蓝图，捍卫家庭、教会等机构的权威。然而，一国保守主义支持通过社会改革来维护国家团结。
Socialism critiques the inequalities generated by capitalism and advocates social ownership or heavy regulation of the means of production. Democratic socialism seeks these goals through electoral methods, while revolutionary socialism aims to overthrow the capitalist state.
社会主义批判资本主义造成的不平等，主张社会所有制或对生产资料进行严格监管。民主社会主义通过选举途径追求这些目标，而革命社会主义则力图推翻资本主义国家。
Other ideologies include anarchism (opposing all forms of coercive state authority), fascism (ultra-nationalist, authoritarian, often racist), and feminism (aiming to end patriarchy and achieve gender equality across public and private spheres).
其他意识形态包括无政府主义（反对一切强制性的国家权威）、法西斯主义（极端民族主义、威权主义且常具种族主义色彩）以及女权主义（旨在终结父权制、在公共与私人领域实现性别平等）。
6. Models of Democracy | 民主模式
Democracy is a system of government by the whole population, typically through elected representatives. Direct democracy, as practised in ancient Athens and in modern referendums, allows citizens to vote on policy questions without intermediaries. The formulation 'initiative + referendum + recall' captures some of its direct tools.
民主是由全体人民——通常通过选举产生的代表——进行治理的制度。直接民主，如古代雅典和现代公投所实践的，允许公民不经中间人而就政策问题投票。“创制 + 复决 + 罢免”这一公式概括了其中部分直接工具。
Representative democracy is more common in large states. Citizens choose representatives who deliberate and legislate on their behalf. Liberal democracy adds the protection of individual rights, the rule of law, and pluralist competition among parties and interest groups. It is often summarised as 'free and fair elections + civil liberties + accountable government'.
代议制民主在大国中更为常见。公民选出代表，由他们代为审议和立法。自由民主则更进一步，保护个人权利、法治，并容纳政党与利益集团的多元竞争。常被概括为“自由公正的选举 + 公民自由 + 负责任的政府”。
Deliberative democracy stresses the quality of discussion. Its proponents argue that decisions should be reached through public reasoning, not just aggregating pre-existing preferences. Participatory democracy emphasises broad citizen engagement beyond voting, including town meetings and civic forums.
审议民主强调讨论的质量。其支持者主张，决策应通过公共推理达成，而非仅仅汇总先验的偏好。参与式民主则注重超越投票的广泛公民参与，诸如市镇会议和公民论坛。
7. Electoral Systems and Duverger’s Law | 选举制度与杜瓦杰定律
An electoral system translates votes into seats. The main families are plurality/majority systems (e.g. First Past the Post, FPTP), proportional representation (PR), and mixed-member systems. Each creates different party-system incentives, which is where political ‘formulae’ become visible.
选举制度将选票转化为席位。主要类别包括多数/过半制（如简单多数制 FPTP）、比例代表制（PR）和混合制。每种制度都会产生不同的政党体系诱因，这便是政治“公式”显现之处。
| System | Key Features | Typical Outcome |
|---|---|---|
| First Past the Post (FPTP) | Single-member districts, winner takes all | Tends towards two-party dominance |
| Closed-list PR | Multi-member districts, party lists | Multi-party system, coalition governments |
| Mixed-Member Proportional (MMP) | Combines constituency seats and list seats | Balances local representation with proportionality |
Duverger’s Law: Single-Member District Plurality → Two-Party System
杜瓦杰定律：单名额选区多数制 → 两党制
Duverger’s Law observes that single-member district plurality elections tend to favour a two-party system. Voters avoid 'wasting' votes on small parties (the psychological effect), and small parties find it hard to win seats (the mechanical effect). The converse suggestion, Duverger’s hypothesis, is that proportional representation encourages multi-partyism.
杜瓦杰定律指出，单名额选区多数制选举倾向于促成两党制。选民不愿在小型政党上“浪费”选票（心理效应），而小型政党难以赢得席位（机械效应）。其反向假说，即杜瓦杰假设，认为比例代表制会促进多党制。
t shareᵢ²), offering a quantitative snapshot of party system fragmentation. This Laakso-Taagepera index helps to measure how ‘concentrated’ a legislature is.
另一个常被引用的规律是，有效政党数（ENP）可通过 ENP = 1/Σ(席位份额ᵢ²) 来估算，为政党体系的碎片化程度提供一个量化快照。这一拉索—塔格佩拉指数有助于度量立法机关的“集中度”。
8. Political Parties and Party Systems | 政党与政党体系
Political parties organise candidates, mobilise voters, and aggregate interests. Their core functions include articulation of ideology, recruitment of political leaders, formulation of policy programmes, and providing a link between citizens and the state.
政党组织候选人、动员选民并汇聚利益。其核心功能包括表述意识形态、招募政治领袖、制定政策纲领，以及在公民与国家之间提供联系纽带。
Party systems are classified by the number of relevant parties and the ideological distance between them. Giovanni Sartori distinguished between two-party systems, moderate pluralism (3–5 parties, centripetal competition) and polarised pluralism (5+ parties with anti-system parties, centrifugal dynamics).
政党体系根据相关政党数量和彼此间的意识形态距离进行分类。乔万尼·萨托利区分出两党制、温和多元主义（3至5个政党，向心竞争）与极化多元主义（5个以上政党且存在反体制政党，离心动态）。
A dominant-party system features one party that consistently wins elections and controls government over a long period, even if opposition parties are legal. In contrast, a one-party state prohibits meaningful competition altogether.
主导党制指某一政党长期赢得选举并控制政府，即便反对党合法存在。与之相对，一党制国家则完全禁止有意义的竞争。
9. Public Opinion, Media and Participation | 舆论、媒体与参与
Public opinion is the aggregation of individuals’ views on political issues. It is shaped by political socialisation agents – family, education, media, peer groups – and measured through opinion polls. The accuracy of a poll depends on sample size, randomness, and question wording.
舆论是个人对政治问题看法的汇聚。它受到政治社会化机构——家庭、教育、媒体、同辈群体——的塑造，并通过民意调查加以测量。民意调查的准确性取决于样本量、随机性和问题措辞。
The mass media play a critical agenda-setting role: they may not tell people what to think, but they powerfully influence what people think about. Today, social media accelerates the spread of both information and disinformation, challenging traditional gatekeepers.
大众媒体扮演着关键的议程设置角色：它们或许不能告诉人们该想什么，却能强有力地影响人们想些什么。如今，社交媒体加速了信息乃至虚假信息的传播，对传统把关人构成挑战。
ns, signing petitions, writing to representatives, and engaging in civil disobedience. The ‘ for a healthy democracy can be expressed as: Participation = Voting + Voice + Association.
政治参与不止于投票。形式包括加入政党、参加示威、签署请愿书、致信代表以及进行公民不服从。一个健康民主的“参与公式”可表达为：参与 = 投票 + 表达 + 结社。
10. Sovereignty, the State and Global Governance | 主权、国家与全球治理
ent population, an effective government, and the capacity to enter into relations with other states – + Population + Government + Sovereignty is a simple yet powerful checklist for statehood.
国家拥有四个基本要素：确定的领土、常住人口、有效的政府，以及与其他国家建立关系的能力——即主权。“国家 = 领土 + 人口 + 政府 + 主权”这一公式是确认国家资格的简洁而有力的清单。
Sovereignty can be understood as supreme legal authority within a territory. However, globalisation, supranational bodies (such as the European Union), and humanitarian interventions have given rise to the idea of pooled or constrained sovereignty, where states voluntarily limit their autonomy to achieve collective goals.
主权可理解为一国领域内的最高法律权威。然而，全球化、超国家机构（如欧盟）以及人道主义干预催生了汇集性或受约束主权的观念，即国家为实现集体目标而自愿限制自主权。
In international relations, realism assumes states are rational, self-interested actors in an anarchic system, focusing on power and security. Liberalism highlights cooperation through institutions, trade, and the spread of democracy, captured in the Kantian notion of ‘perpetual peace’. Constructivism argues that state interests are socially constructed through norms, identities and discourse.
在国际关系中，现实主义假设国家是无政府体系中的理性、自利行为体，关注权力与安全。自由主义则强调通过制度、贸易和民主扩散来实现合作，这体现于康德的“永久和平”理念。建构主义认为，国家利益是通过规范、身份认同和话语社会建构出来的。
