📚 Year 12 AQA Politics: Key Concepts & Theories Quick Reference | AQA 政治 Year 12：公式定理速查手册

This revision resource is designed as a rapid-reference ‘formula sheet’ for Year 12 AQA Politics. Just as equations underpin the natural sciences, a set of key concepts, models, laws and institutional ‘rules of the game’ structures the study of UK government, politics and core political ideas. Use this handbook to memorise definitions, frameworks and causal relationships that commonly appear in AQA exam questions.

这份复习资料是专为 Year 12 AQA 政治课程设计的“公式定理速查手册”。正如自然科学依赖方程式，英国政府与政治以及核心政治理念的学习也建立在一系列关键概念、模型、定律和制度“游戏规则”之上。请利用本手册牢记那些频繁出现在 AQA 考题中的定义、分析框架和因果关系。

1. Democracy: Direct vs Representative | 民主：直接民主与代议制民主

Democracy means ‘rule by the people’. In a direct democracy, citizens make policy decisions themselves without intermediaries. Modern examples include referendums and town meetings. AQA requires you to distinguish this from representative democracy, where voters elect officials to act on their behalf. The UK is a representative democracy with some direct elements, such as the 2016 EU referendum.

民主意味着“人民统治”。在直接民主制中，公民不经中间人直接做出政策决定，现代例子包括全民公投和市民大会。AQA 要求你将此与代议制民主区分开来，后者由选民选举代表代为行事。英国是一个带有某些直接民主元素的代议制民主国家，例如 2016 年的脱欧公投。

A crisis of democratic legitimacy can occur when turnout falls, trust in politicians declines or participation gaps emerge based on age and class. Theorists such as Schumpeter define democracy narrowly as a competition for the people’s vote, whereas participatory democrats demand much wider civic engagement.

当投票率下降、对政治人物的信任度降低或者因年龄与阶级差异出现参与鸿沟时，就可能发生民主合法性危机。熊彼特等理论家将民主狭义地定义为争取民众选票的竞争，而参与式民主论者则要求更广泛的公民参与。

2. Political Participation and Pressure Groups | 政治参与与压力团体

Political participation extends beyond voting to include joining a party, protesting, signing petitions and engaging in online activism. AQA identifies a participation crisis in the UK, evidenced by declining party memberships and low turnout in some elections despite recent surges around high-salience issues.

政治参与不仅包括投票，还包括加入政党、抗议、签署请愿书以及网络行动主义。AQA 指出英国正在经历一场参与危机，证据包括政党党员人数下降以及某些选举中投票率偏低，尽管近期一些高关注度议题曾引发参与热潮。

Pressure groups are organised collections of individuals seeking to influence policy without seeking office. Insider groups (e.g. NFU, BMA) enjoy privileged access to ministers, while outsider groups (e.g. Extinction Rebellion, Greenpeace) must rely on public campaigns and direct action. Their success can be assessed using the ‘power triangle’ linking group resources, government appetite and public sympathy.

压力团体是有组织地试图影响政策却不谋求公职的群体。圈内团体（如全国农民联盟、英国医学会）享有接触部长的特权，而圈外团体（如反抗灭绝、绿色和平）则必须依赖公众运动和直接行动。衡量其成败可以利用“权力三角”，即团体资源、政府意愿与公众同情三者的联系。

3. UK Political Parties and Party Systems | 英国政党与政党制度

A political party is an organised group that contests elections in order to gain office and implement a programme based on shared values. The major UK parties — Conservative, Labour and Liberal Democrats — each maintain distinct ideological profiles, ranging from One-Nation conservatism to social democracy and democratic socialism, alongside a liberal tradition.

政党是为了赢得公职并根据共同价值观实施纲领而有组织地参与选举的团体。英国主要政党——保守党、工党和自由民主党——各自保持着鲜明的意识形态特征，从一国保守主义到社会民主主义和民主社会主义，再加上自由主义传统。

Duverger’s Law acts as a political theorem predicting that single-member plurality electoral systems favour a two-party system. In the UK the first-past-the-post system has historically produced single-party majority governments, though devolution and recent fragmentation challenge this.

迪韦尔热定律如同一则政治学定理，它预测单名选区简单多数选举制有利于两党制。在英国，简单多数制历史上往往催生一党多数政府，尽管权力下放和近期的碎片化趋势对这一格局发起了挑战。

Duverger’s Law: SMDP → Two-party tendency

迪韦尔热定律：单名多数制 → 两党化倾向

4. Electoral Systems: Key Formulas | 选举制度：关键公式

The UK uses different electoral systems for various bodies. The three main options assessed by AQA are First Past the Post (FPTP), Additional Member System (AMS) and Single Transferable Vote (STV). Each contains calculable rules that determine seat allocation.

英国各机构使用不同的选举制度。AQA 考查的三种主要制度是简单多数制（FPTP）、附加入围制（AMS）和单一可转移投票制（STV）。每种制度都包含可以计算的决定席位分配的规则。

Under FPTP, the candidate with the most votes in a constituency wins. No quota formula is needed; victory requires only a plurality. This system creates a ‘winner’s bonus’ for the largest party and excludes smaller parties unless their support is geographically concentrated.

在简单多数制下，各选区得票最多的候选人胜出。无需任何配额公式；只要获得相对多数即可。这一制度为最大党制造了“胜者红利”，并将小党排除在外，除非它们的支持票在地理上高度集中。

FPTP: Seat is won if Vₐ > Vₓ (all other candidates) in constituency

FPTP：若候选人在选区得票 Vₐ > Vₓ（所有其他候选人），即赢得议席

STV requires a quota to ensure proportionality. The Droop quota is used to elect candidates in multi-member constituencies. Any candidate reaching the quota is elected; surplus votes are transferred to next preferences.

STV 要求使用配额来确保比例性。德鲁普配额用于在多议席选区选举候选人。任何达到配额的候选人即告当选，多余选票会转移给下一偏好。

Droop Quota: (Total valid votes ÷ (Seats + 1)) + 1

德鲁普配额：(有效票总数 ÷ (议席数 + 1)) + 1

AMS combines constituency MPs elected via FPTP with regional list seats allocated by the d’Hondt formula. Parties are ranked by their list votes; each party’s vote total is divided successively by 1, 2, 3, and so on. The highest quotients win seats.

AMS 将通过 FPTP 产生的选区议员与按 d’Hondt 公式分配的区域名单议席结合起来。各政党按名单得票数排序，每个政党的得票数依次除以 1、2、3…，商数最高的那些赢得议席。

d’Hondt divisor sequence: Seats allocated by highest quotients (Votes ÷ 1, ÷ 2, ÷ 3 …)

洪德除数序列：按最高商数分配议席（得票 ÷ 1、÷ 2、÷ 3 …）

5. Voting Behaviour and Models | 投票行为与模型

Explaining why people vote as they do is central to AQA UK Politics. The three classic models are the sociological model (class, region, religion), the party-identification model (psychological attachment to a party) and the rational-choice model (voters weigh policies and competence).

解释人们为何以某种方式投票是 AQA 英国政治的核心内容。三种经典模型为：社会学模型（阶级、地区、宗教）、政党认同模型（对某一政党的心理依恋）和理性选择模型（选民权衡政策与执政能力）。

Since the 1970s, class dealignment has eroded traditional working-class Labour support and middle-class Conservative support. Partisan dealignment has also occurred, with more voters becoming ‘floating voters’. Governing-competence valence issues — such as economic management and leadership — now heavily influence outcomes.

自 20 世纪 70 年代以来，阶级淡化侵蚀了传统上工人阶级对工党的支持以及中产阶级对保守党的支持。政党认同淡化也已出现，更多的选民成为“摇摆选民”。执政能力的效价议题，如经济管理与领导力，如今对选举结果影响甚大。

Voting behaviour formula: Vote choice ≈ f (class, party ID, issue valence, leadership, media)

投票行为公式：投票选择 ≈ f（阶级、政党认同、议题效价、领导力、媒体）

6. The UK Constitution: Principles | 英国宪法：基本原则

The UK constitution is uncodified (not written in a single document), unentrenched (can be changed by ordinary legislation) and unitary (sovereignty theoretically resides in Parliament, although devolution has distributed powers to Scotland, Wales and Northern Ireland).

英国宪法是非法典化的（并非写在单一文件中）、非刚性固化的（可通过普通立法修改）和单一制的（主权在理论上属于议会，尽管权力下放已将权力分给苏格兰、威尔士和北爱尔兰）。

Central to the constitution is the doctrine of parliamentary sovereignty, classically expressed by A. V. Dicey: Parliament can make or unmake any law, and no person or body can override primary legislation. A rival principle is the rule of law, which requires that all are equal before the law and that power must be exercised within legal boundaries.

宪法的核心是议会主权原则，由戴西经典地表述为：议会可以制定或废除任何法律，且任何个人或机构都不能推翻初级立法。与之并立的另一原则是法治，它要求法律面前人人平等，权力必须在法律界定的范围内行使。

The twin pillars of parliamentary sovereignty and the rule of law sometimes conflict. The EU membership period (1973–2020) saw sovereignty pooled, while the Human Rights Act 1998 gave judges stronger interpretive powers. These tensions continue to shape contemporary debates about a codified constitution.

议会主权与法治这两大支柱有时会发生冲突。加入欧盟期间（1973–2020），主权被部分汇集，而《1998 年人权法案》则赋予了法官更强的解释权。这些张力继续影响着当下关于是否应该制定一部成文宪法的辩论。

7. Parliament: Composition and Functions | 议会：组成与职能

Parliament consists of the House of Commons (650 elected MPs), the House of Lords (around 800 unelected peers, including life peers, hereditary peers and bishops) and the monarch, whose role is now ceremonial. AQA expects you to understand the bicameral structure and its functions.

议会由下议院（650 名选举产生的议员）、上议院（约 800 名不经选举产生的贵族，包括终身贵族、世袭贵族和主教）以及君主组成，君主的作用如今已是礼仪性的。AQA 要求你理解这一两院制结构及其职能。

The core functions of Parliament are legislation (making statute law), scrutiny of the executive (through questions, select committees and debates), representation of constituents and providing government. Parliament is not, however, a policy-making body in its own right; the government dominates the legislative timetable.

议会的核心职能包括立法（制定成文法）、监督行政部门（通过质询、特设委员会和辩论）、代表选民以及提供政府。然而，议会本身并非独立的决策机构；政府主导着立法时间表。

Select committees have gained influence, conducting evidence-based inquiries that can humble ministers. The Commons also controls supply (granting money to the executive), and backbench rebellions sometimes defeat government bills, demonstrating a ‘revising and checking’ function.

特设委员会的影响力日益增强，它们进行的循证调查能让部长们难堪。下议院还控制着财政（向行政部门拨款），而后座议员的反叛有时会击败政府法案，这体现了“修订与制衡”的职能。

8. The Prime Minister and Cabinet | 首相与内阁

The prime minister is the head of government, appointed by the monarch on the understanding that they command the confidence of the House of Commons. Formal powers include patronage (appointing and dismissing ministers), chairing the Cabinet, controlling the Cabinet agenda and determining departmental mandates.

首相是政府首脑，由君主任命，前提是首相能获得下议院的信任。其正式权力包括任命与罢免大臣的人事权、主持内阁、掌控内阁议程以及决定各部门的职责范围。

Power within the executive is analysed through two competing models: cabinet government (where ministers collectively decide policy) and prime ministerial government (where the PM dominates). More recently, the concept of ‘core executive’ captures the complex network of relationships among PM, Cabinet, Cabinet committees and senior officials.

行政分支内部的权力通过两个竞争模型来分析：内阁政府（大臣集体决定政策）和首相政府（首相为主导）。近年来，“核心行政”这一概念则捕捉了首相、内阁、内阁委员会以及高官之间复杂的互动网络。

Constraints on prime ministerial power include a small majority, rebellious backbenchers, coalition partners, public opinion and events. The ‘presidentialisation’ thesis suggests the PM increasingly behaves like a head of state, but institutional limits remain significant.

对首相权力的制约包括微弱的多数优势、反叛的后座议员、联合执政伙伴、公众舆论和突发事件。“总统化”论认为首相的行为越来越像国家元首，但制度性限制依然重要。

9. The Judiciary and Rule of Law | 司法与法治

Under the constitutional reform agenda, the Constitutional Reform Act 2005 created a Supreme Court physically separate from the House of Lords and reformed the role of the Lord Chancellor, strengthening judicial independence. AQA examines the judiciary’s role in upholding the rule of law and checking executive power.

在宪政改革议程下，《2005 年宪政改革法》创设了从物理上与上议院分开的最高法院，并改革了大法官的职责，从而加强了司法独立。AQA 考查司法机构在维护法治和制约行政权方面的作用。

Judicial review is the process by which judges examine whether a public body has acted lawfully. They cannot strike down primary legislation under the principle of parliamentary sovereignty, but they can issue a declaration of incompatibility under the Human Rights Act 1998, pressuring Parliament to amend the law.

司法审查是法官审视公共机构是否依法行事的程序。根据议会主权原则，他们不能推翻初级立法，但可以根据《1998 年人权法案》发布不相容声明，以此向议会施压要求修改法律。

The independence of the judiciary is safeguarded by security of tenure, guaranteed salaries and the sub judice rule. Tensions between government and courts have grown in recent years, particularly around the Miller cases and parliamentary sovereignty versus prerogative powers.

司法独立由任期保障、薪酬保障和“案件审理中”规则来守护。近年来，政府与法院之间的紧张关系有所加剧，尤其体现在米勒案以及议会主权与特权权力的冲突之中。

10. Core Political Ideas: Liberalism, Conservatism, Socialism | 核心政治理念：自由主义、保守主义、社会主义

Liberalism is built on individualism, freedom, reason, justice and toleration. Classical liberals (e.g. Locke, J. S. Mill) champion minimal state intervention and negative liberty, whereas modern liberals (e.g. Rawls, T. H. Green) endorse an enabling state and positive liberty through welfare and education.

自由主义建立在个人主义、自由、理性、正义和宽容之上。古典自由主义者（如洛克、密尔）主张最小国家干预和消极自由，而现代自由主义者（如罗尔斯、格林）则支持赋能型国家以及通过福利和教育实现的积极自由。

Conservatism emphasises tradition, human imperfection, organic society, authority and property. One-Nation conservatives (e.g. Disraeli) accept pragmatic reform to preserve social cohesion, while the New Right combines free-market economics (neoliberalism) with a limited state and traditional values (neoconservatism).

保守主义强调传统、人性的不完美、有机社会、权威和财产权。一国保守主义者（如迪斯雷利）接受务实改革以维系社会凝聚，而新右派则融合了自由市场经济学（新自由主义）与有限国家及传统价值观（新保守主义）。

Socialism shares a collectivist ethos and a critique of capitalism. Revolutionary socialists (Marx, Engels) sought to overthrow capitalism entirely, whereas social democrats (Webb, Crosland) advocate a mixed economy, progressive taxation and welfare to tame capitalism’s inequalities. The Third Way (Giddens, Blair) further reconciles market efficiency with social justice.

社会主义具有集体主义精神和对资本主义的批判。革命社会主义者（马克思、恩格斯）谋求彻底推翻资本主义，而社会民主主义者（韦伯夫妇、克罗斯兰）倡导混合经济、累进税和福利制度来驯服资本主义的不平等。第三条道路（吉登斯、布莱尔）则进一步调和了市场效率与社会正义。

Ideological ‘equation’: Liberalism = individual freedom + rationalism; Conservatism = tradition + order; Socialism = equality + community

意识形态“方程式”：自由主义 = 个人自由 + 理性主义；保守主义 = 传统 + 秩序；社会主义 = 平等 + 共同体
