1. Power Formula | 权力公式

Power is the ability to make others do something they would not otherwise do. At its simplest, power can be expressed as:

Power = Capacity × Resources

Capacity includes the will to act, political skill and the capacity to mobilise resources effectively. Resources may be material (money, armed force), institutional (office, legal rights) or symbolic (legitimacy, charisma). The formula reveals that even vast resources produce little power if capacity is absent, while a skilled operator with modest means can exert considerable influence. This is the foundation of all political analysis.

权力是使他人做其本不会做之事的能力。简单来说，权力可以表示为：

权力 = 能力 × 资源

能力包括行动的意志、政治技巧以及有效调动资源的能力。资源可以是物质的（金钱、武装力量）、制度的（官职、法律权利）或象征性的（合法性、魅力）。该公式揭示出，若无能力，即便资源庞大也产生不了多少权力；而手段有限但技巧娴熟的操作者则能施加可观影响。这是所有政治分析的基础。

2. Theorem of Authority Types | 权威类型定理

Max Weber identified three pure types of legitimate authority. These can be treated as a classification theorem:

Type	Basis of Legitimacy	Example
Traditional	Long-standing customs, inheritance	Hereditary monarch
Charismatic	Personal devotion to an extraordinary leader	Revolutionary figure
Legal-rational	Enacted rules and the right of office-holders under those rules	Modern civil servant

The theorem states that every political system rests on a mixture, but one type tends to dominate. In practice, charisma becomes routinised into traditional or legal-rational forms to ensure stability. This tool allows you to dissect regime legitimacy instantly.

马克斯·韦伯确定了三种纯粹的合法权威类型，可视为一个分类定理：

类型	合法性基础	实例
传统型	悠久习俗、继承	世袭君主
魅力型	对超凡领袖的个人献身	革命人物
法理型	成文规则及据此规则履职者的权利	现代公务员

该定理表明，每个政治体系都建立在混合基础上，但一种类型往往占主导。在实践中，魅力型权威会常规化，转为传统型或法理型以维持稳定。借助这个工具，你可以迅速剖析政权的合法性来源。

3. Formula of Sovereignty’s Four Pillars | 主权四大支柱公式

Sovereignty is not a vague concept; it can be broken into four indivisible pillars. The formula is:

Sovereignty = Internal Supremacy + External Independence + Legal Equality + Territorial Integrity

Internal supremacy means the state is the highest authority within its borders. External independence refers to freedom from outside control. Legal equality denotes equal standing under international law. Territorial integrity requires defined, inviolable borders. A deficiency in any pillar weakens sovereignty: ceding border control to a supranational body erodes territorial integrity, while foreign military bases may compromise external independence.

主权并非模糊的概念；它可以分解为四个不可分割的支柱。公式为：

主权 = 对内最高 + 对外独立 + 法律平等 + 领土完整

对内最高意味着国家在其境内是最高权威。对外独立指不受外部控制。法律平等表示在国际法下享有平等地位。领土完整要求有明确、不可侵犯的边界。任何一个支柱的缺失都会削弱主权：将边境控制权让渡给超国家机构会侵蚀领土完整，而外国军事基地可能损害对外独立。

4. Democracy Index Theorem | 民主指数定理

A working democracy can be assessed through a composite theorem built on five core dimensions. The theorem reads:

Democracy Score = Electoral Process & Pluralism × Functioning Government × Political Participation × Political Culture × Civil Liberties

Each dimension is weighted in practice; the product analogy highlights that failure in one area drastically reduces the overall score. Full democracies achieve high marks across all five; flawed democracies show deficits in participation or culture; hybrid regimes combine authoritarian features with some electoral pluralism. This formula helps make sense of indices such as the Economist Intelligence Unit’s Democracy Index.

评估运作中的民主，可借助一个基于五个核心维度的综合定理。定理如下：

民主得分 = 选举进程与多元化 × 政府运作 × 政治参与 × 政治文化 × 公民自由

每个维度在实践中均有权重；乘积式类比突显出一个领域的失败会大幅拉低总分。完全民主体在所有五项上得分都高；有缺陷的民主体在参与或文化上存在不足；混合政体则结合了威权特征与一定的选举多元化。这一定理有助于理解经济学人智库的民主指数等指标。

5. Representation Formula: Delegate vs Trustee | 代表公式：委托型与受托型

The roles elected representatives adopt can be modelled on a continuum between the delegate and trustee mandates. The governing formula is:

Representation Outcome = (Delegate Weight × Constituency Wishes) + (Trustee Weight × Representative’s Judgement)

When the delegate weight approaches 1, the representative acts as a mouthpiece, faithfully echoing constituents’ preferences even against personal belief. When the trustee weight approaches 1, the representative follows Burkean reasoning, using independent judgement to decide what is best for the nation. Most MPs operate somewhere in between, adjusting the weights according to issue salience and party whip.

民选代表所扮演的角色可模拟为委托型与受托型授权之间的连续体。支配公式为：

代表结果 = (委托权重 × 选区意愿) + (受托权重 × 代表判断)

当委托权重趋近于1时，代表充当传声筒，忠实地回应选民偏好，即便违背个人信念。当受托权重趋近于1时，代表遵循伯克式推理，运用独立判断来决定何者对全国最有利。多数议员处于两者之间，根据议题显著性和政党鞭策调整权重。

6. Electoral System Formulas: Majoritarian, Proportional and Mixed | 选举制度公式：多数制、比例制与混合制

Electoral systems translate votes into seats through distinct mechanical formulas. The major types with their core equations are:

FPTP: Winner = Candidate with max(Votes) in each single-member district

List PR: Seat share ≈ Vote share, often adjusted by a threshold

Supplementary Vote (SV): If no candidate obtains >50% of first preferences, the top two proceed, and second preferences of eliminated candidates are redistributed until one reaches a majority

System	Formula Essence	Typical Effect
FPTP	Plurality wins, single-member districts	Disproportional results, two-party tendency
SV	Majority ensured via instant runoff	Winner with broad support, still single-member
List PR	Seats = (Party Votes / Total Valid Votes) × Total Seats	High proportionality, multi-party systems
STV	Droop quota: Votes/(Seats+1) +1; preferences transferred	Proportional within multi-member constituencies

These formulas are the building blocks for every discussion of electoral reform and party system outcomes. Understanding the mechanical effect is essential for analysing why a party with 35% of the vote might still form a majority government under FPTP while a similar share under PR leaves it as a minority coalition partner.

选举制度通过独特的机械公式将选票转化为席位。主要类型及其核心方程如下：

FPTP：胜者 = 每个单席选区中得票最多的候选人

名单比例代表制：席位份额 ≈ 得票份额，通常经门槛调整

补充投票制：若无候选人首轮得票超过50%，前两名晋级，被淘汰候选人的第二偏好票被重新分配，直至一人过半数
