📚 Year 11 CAIE Economics: Vocabulary & Terminology Memorisation Guide | Year 11 CAIE 经济：词汇术语速记指南
Mastering the specific vocabulary and terminology in CAIE IGCSE or O Level Economics is not just about memorising definitions—it is about learning to think like an economist. Every exam question, from multiple choice to structured essays, demands precise use of terms such as 'opportunity cost', 'price elasticity of demand' or 'fiscal policy'. A clear understanding and rapid recall of these terms will help you eliminate distractors in Paper 1, build coherent chains of analysis in Paper 2, and impress examiners. This guide is designed to give you effective memorisation techniques and a structured walk-through of the core vocabulary you need in Year 11.
掌握 CAIE IGCSE 或 O Level 经济课程中的术语不仅是背诵定义，更是学会像经济学家一样思考。从选择题到结构化论述题，每一类考题都要求你精准使用“机会成本”、“需求价格弹性”或“财政政策”等术语。清晰地理解并能快速回忆这些词语，能帮你在卷一排除干扰项、在卷二构建有逻辑的分析链，并给考官留下深刻印象。这份速记指南将为你提供高效的记忆方法，并系统梳理 Year 11 必须掌握的核心词汇。
1. Why Mastering Terminology is Critical for CAIE Economics | 为何掌握术语对 CAIE 经济至关重要
Command terms, keywords and economic jargon form the backbone of the mark scheme. A student who can distinguish between a 'movement along the demand curve' and a 'shift of the demand curve' already has a major advantage. Terminology is the tool that turns vague descriptions into analytical arguments. In Paper 2, using the phrase 'contraction in quantity demanded' instead of just 'demand goes down' can be the difference between a Level 2 and a Level 3 mark. This precision signals to the examiner that you possess higher-order understanding.
指令词、关键词和经济学术语构成了评分方案的骨干。能区分“沿需求曲线的移动”与“需求曲线的平移”的学生已经占据了巨大优势。术语是将模糊的描述转变为分析性论证的工具。在卷二，使用“需求量收缩”这个短语，而不仅仅是“需求下降”，可能决定着你从二级评分跃升到三级评分。这种精准向考官表明你具备高阶理解。
Moreover, memorising definitions efficiently frees up cognitive load during the exam. If you do not need to waste time mentally reconstructing 'inflation', you can focus on application and evaluation. Therefore, building a robust mental glossary is both a short-term revision win and a long-term economics skill.
此外，高效记忆定义能在考试中释放认知负担。如果你不用花时间去脑海中重建“通货膨胀”的含义，你就能专注于应用和评估。因此，建立一个牢固的大脑术语库既是短期复习的胜利，也是长期的经济学技能。
2. The ‘Active Recall’ Method for Definitions | “主动回忆”法记忆定义
Passively reading glossaries is one of the least effective ways to learn. Instead, use active recall: cover the definition, try to recall it word for word, then check. This forces your brain to retrieve the information, strengthening memory pathways. Write your definitions as concise, examiner-friendly statements. For CAIE, a standard economic definition typically contains the term itself, the category it belongs to, and one or two distinguishing features. For example, 'Opportunity cost is the next best alternative forgone when an economic choice is made.'
被动浏览词汇表是最低效的学习方式之一。相反，要使用主动回忆法：遮住定义，尝试逐字回忆，然后核对。这会迫使你的大脑提取信息，加固记忆路径。将自己的定义写成简洁、对评分者友好的陈述。对于 CAIE，一个标准的经济学定义通常包含术语本身、它所属的类别以及一两个区分性特征。例如，“机会成本是做出经济选择时所放弃的次优替代选项”。
Combine this with the Feynman Technique: explain the term to another person, or even to an empty chair, using simple language and a concrete example. If you can teach it, you know it. Keep a stack of flashcards, physical or digital, with the term on one side and the definition plus an example on the other. Test yourself daily in short bursts of 10–15 minutes.
将此与费曼技巧结合：用简单的语言和具体例子向他人解释这个术语，哪怕是向一把空椅子。如果你能教会别人，你就真正懂了。准备一叠抽认卡，纸质或电子版均可，正面写术语，背面写定义加一个例子。每天用 10 到 15 分钟进行自我测试。
3. Key Microeconomics Terms (Scarcity, Opportunity Cost, Factors of Production) | 微观经济核心术语（稀缺性、机会成本、生产要素）
The foundation of all economics is the basic economic problem: scarcity. Scarcity is the condition where unlimited human wants exceed limited resources. This leads to the need for choice and, ultimately, opportunity cost. Ensure you can state that 'resources are finite while wants are infinite', and link this directly to the concept of opportunity cost in any decision—whether by consumers, firms or governments.
一切经济学的基石是基本经济问题：稀缺性。稀缺性是指无限的人类欲望超出有限资源的状态。这导致选择的必要性，最终产生了机会成本。务必能够阐述“资源是有限的而欲望是无限的”，并将其与消费者、企业或政府任何决策中的机会成本概念直接联系。
The factors of production—land, labour, capital and enterprise—must be recalled with their associated factor incomes: rent, wages, interest and profit. A common trick is to think of the acronym 'CELL' (Capital, Enterprise, Land, Labour) and remember 'CELL earns R-W-I-P' (Rent, Wages, Interest, Profit). These definitions often appear as quick one-mark questions in Paper 1.
生产要素——土地、劳动、资本和企业家才能——必须连同其对应的要素收入一起记忆：地租、工资、利息和利润。一个常见的技巧是记忆首字母缩写“CELL”（资本、企业家才能、土地、劳动），并记住“CELL 赚取 R-W-I-P”（地租、工资、利息、利润）。这些定义经常作为卷一的一分快答题出现。
4. Demand and Supply: The Must-Know Shifter Terms | 需求与供给：必知的移动因素术语
Memorise the difference between a 'movement along' and a 'shift of' the demand or supply curve. A movement along occurs solely due to a change in the good's own price (contraction or extension). A shift occurs when any other determinant changes—these are often remembered with the acronyms 'PASIFIC' for demand (Population, Advertising, Substitutes' prices, Income, Fashion/tastes, Interest rates (for credit purchases), Complements' prices) and 'PINTS WC' for supply (Productivity, Indirect taxes, Number of firms, Technology, Subsidies, Weather, Costs of production).
记住需求或供给曲线“沿曲线的移动”和“曲线的平移”之间的区别。沿曲线的移动仅由商品自身价格变化引起（收缩或扩张）。曲线的平移是在任何其他决定因素发生变化时发生——这些因素通常用首字母缩写来记忆：需求用“PASIFIC”（人口、广告、替代品价格、收入、时尚/偏好、利率（针对信贷购买）、互补品价格），供给用“PINTS WC”（生产率、间接税、企业数量、技术、补贴、天气、生产成本）。
Never write 'demand increases' when you mean 'quantity demanded increases'. The former describes a rightward shift of the entire curve; the latter describes a movement along the curve downwards due to a price fall. This distinction is relentlessly tested in multiple-choice questions.
当你想表达“需求量增加”时，千万不要写成“需求增加”。前者描述的是整条曲线向右平移；后者描述的是由于价格下降而沿曲线向下移动。这个区别在选择题中会被反复考查。
5. Elasticity Vocabulary: PED, PES, YED, XED | 弹性词汇：PED、PES、YED、XED
are: Price Elasticity of Demand (PED), Price Elasticity of Supply (PES), Income Elasticity of Demand (YED), and Cross Elasticity of Demand (XED). Learn the formulas precisely: PED = % change in quantity demanded ÷ % stic, zero mean perfectly inelastic, and infinity mean perfectly elastic. Use the mnemonic 'Elastic is Expandable'—if demand is elastic, total revenue expands when price falls.
弹性衡量一个变量对另一个变量变化的反应程度。你必须会定义、计算和解释的四种关键弹性是：需求价格弹性（PED）、供给价格弹性（PES）、需求收入弹性（YED）和需求交叉弹性（XED）。精确掌握公式：PED = 需求量变动百分比 ÷ 价格变动百分比。对于 PED，数值大于 1 为富有弹性，小于 1 为缺乏弹性，恰好等于 1 为单位弹性，0 为完全无弹性，无穷大为完全弹性。用一句助记“弹性就是可扩张”——如果需求富有弹性，价格下降时总收益会增加。
YED is particularly useful for distinguishing normal goods (YED > 0) from inferior goods (YED < 0). XED identifies substitutes (XED > 0) and complements (XED < 0). When revising, always pair the definition with a real-world product—for example, a YED of +2.5 for luxury cars means they are highly income-elastic, whereas a YED of −0.4 for public bus transport marks it as an inferior good.
YED 对于区分正常品（YED > 0）和低档品（YED < 0）特别有用。XED 则用于识别替代品（XED > 0）和互补品（XED < 0）。复习时，总是将定义与一个现实产品配对——例如，豪华车的 YED 为 +2.5 表明其高度收入弹性，而公共汽车的 YED 为 −0.4 则将其标记为低档品。
6. Market Failure and Government Intervention Terms | 市场失灵与政府干预术语
de: public goods (non-rivalry, non-excludability), merit goods and demerit goods (under-consumed or over-consumed due to imperfect information), externalities (positive or negative spillover effects on third parties), and social costs/benefits. Use the formula: Social Cost = Private Cost + External Cost. Draw simple diagrams to label the welfare loss triangles—visual memory is very powerful for these terms.
市场失灵发生在价格机制无法有效配置资源，导致社会净福利损失时。此处核心术语包括：公共品（非竞争性、非排他性）、有益品和有害品（因信息不充分而被消费不足或过度消费）、外部性（给第三方带来的正面或负面溢出效应）以及社会成本/收益。使用公式：社会成本 = 私人成本 + 外部成本。画出简图并标记福利损失三角形——视觉记忆对这些术语非常有效。
Government intervention vocabulary includes: indirect taxes (specific and ad valorem), subsidies, price ceilings (maximum prices), price floors (minimum prices), tradable pollution permits, and government provision. For each, you should be able to link the intervention to a diagrammatical analysis showing how it corrects the market failure. Memorise that an indirect tax shifts the supply curve leftward by the amount of the tax, and that a subsidy shifts it rightward.
政府干预的词汇包括：间接税（从量税和从价税）、补贴、价格上限（最高价格）、价格下限（最低价格）、可交易污染许可证以及政府直接提供。对于每一个术语，你应能将其与显示如何纠正市场失灵的图形分析联系起来。记住，间接税使供给曲线向左平移税收金额，而补贴使其向右平移。
7. Macroeconomics Core Indicators: GDP, Inflation, Unemployment | 宏观经济核心指标：GDP、通胀、失业
Gross Domestic Product (GDP) is the total value of all goods and services produced within a country's borders in a given time period. Do not confuse it with GNP. Nominal GDP is at current prices; real GDP is adjusted for inflation. A 'recession' is technically two consecutive quarters of negative economic growth. Inflation is a sustained rise in the general price level, measured by the Consumer Price Index (CPI). Deflation is the opposite—a sustained fall in the general price level—and disinflation means a reduction in the rate of inflation.
国内生产总值（GDP）是指在一定时期内，一国境内生产的所有最终商品和服务的总价值。不要与国民生产总值混淆。名义 GDP 按现价计算；实际 GDP 经通胀调整。“衰退”的技术定义是连续两个季度出现负经济增长。通货膨胀是一般物价水平的持续上升，通过消费者价格指数（CPI）衡量。通货紧缩则相反——一般物价水平的持续下降——而去通胀则是指通胀率下降。
Unemployment terms include: the claimant count and the labour force survey, as well as types of unemployment such as cyclical (demand-deficient), structural (mismatch of skills), frictional (between jobs) and seasonal. Knowing the specific causes and cures for each type is a high-value revision target for extended responses.
失业术语包括：申领失业金人数和劳动力调查，以及失业类型如周期性失业（需求不足型）、结构性失业（技能错配）、摩擦性失业（过渡期）和季节性失业。了解每种类型的具体原因和治理方法，是拓展题高分复习的重点。
8. Fiscal and Monetary Policy Instruments | 财政与货币政策工具
Fiscal policy involves government manipulation of taxation and government spending to influence aggregate demand. Key terms: expansionary fiscal policy (cutting taxes and/or increasing spending to boost AD), contractionary fiscal policy, budget deficit (spending > tax revenue), budget surplus, and national debt. Learn the difference between direct taxes (on income and wealth, e.g. income tax) and indirect taxes (on spending, e.g. VAT).
财政政策涉及政府通过操纵税收和政府支出来影响总需求。关键术语：扩张性财政政策（减税和/或增加支出以刺激总需求）、紧缩性财政政策、预算赤字（支出 > 税收收入）、预算盈余以及国债。学会区分直接税（对收入和财富征收，如所得税）和间接税（对支出征收，如增值税）。
Monetary policy is carried out by the central bank and focuses on the money supply and interest rates. The base rate is the key policy rate. Quantitative easing (QE) is an unconventional tool where the central bank purchases assets to inject money directly into the economy. Exchange rate policy is also often under the central bank's remit. When revising, link each policy to its effect on the components of aggregate demand: Consumption (C), Investment (I), Government spending (G), and Net Exports (X-M).
货币政策由中央银行执行，重点在于货币供应和利率。基准利率是关键政策利率。量化宽松（QE）是一种非常规工具，中央银行通过购买资产直接将资金注入经济。汇率政策通常也属于央行的职责范围。复习时，将每项政策与其对总需求各组成部分的影响联系起来：消费（C）、投资（I）、政府支出（G）和净出口（X-M）。
9. International Trade and Exchange Rates | 国际贸易与汇率
International trade vocabulary centres on comparative advantage (the ability to produce a good at a lower opportunity cost than another country), absolute advantage, free trade, protectionism, and the terms of trade. Tariffs, quotas, subsidies to domestic producers and embargoes are the main protectionist tools. Know that a tariff diagram shows a rise in domestic price, a contraction in imports, and a deadweight loss.
国际贸易词汇围绕比较优势（以低于另一国的机会成本生产某种商品的能力）、绝对优势、自由贸易、保护主义和贸易条件展开。关税、配额、对国内生产者的补贴和禁运是主要的保护主义工具。要明白关税图显示国内价格上涨、进口收缩和社会净损失。
An exchange rate is the price of one currency in terms of another. A depreciation (or devaluation in a fixed system) means the currency's value falls, making exports cheaper and imports more expensive. An appreciation (or revaluation) does the opposite. Use the acronym 'SPICED' to remember: Strong Pound Imports Cheaper Exports Dearer. Pay attention to the words 'depreciation' (floating regime) and 'devaluation' (fixed regime)—they are not interchangeable.
汇率是以另一种货币表示的一种货币的价格。贬值（浮动制度下）或法定贬值（固定制度下）意味着货币价值下降，使得出口更便宜、进口更昂贵。升值或法定升值则相反。用“SPICED”助记：强势英镑，进口便宜出口贵。注意“depreciation”（浮动制）和“devaluation”（固定制）这两个词不可互换。
10. Common Confusions and How to Avoid Them | 常见混淆点及避错指南
Many CAIE candidates lose marks by confusing similar-sounding terms. The list below should be your accuracy checklist:
许多 CAIE 考生因混淆发音相似的术语而失分。下表应成为你的准确性检查清单：
| Common Confusion | Clarification |
| 'Inflation' vs 'Deflation' vs 'Disinflation' | Inflation: rising price level. Deflation: falling price level. Disinflation: falling inflation rate (prices still rising but more slowly). |
| 'Subsidy' vs 'Tax' | Subsidy shifts supply right; tax shifts supply left. |
| 'Budget deficit' vs 'National debt' | Deficit is annual shortfall; debt is accumulated deficits over time. |
| 'Normal good' vs 'Inferior good' | Normal: demand rises as income rises. Inferior: demand falls as income rises. |
| 'Privatisation' vs 'Nationalisation' | Privatisation sells state assets to private sector; nationalisation brings them under government control. |
| 'Productivity' vs 'Production' | Production is output level; productivity is output per unit of input. |
Use flashcards specifically to drill these distinctions. In the exam, if you are unsure, underline the key suffix or prefix: 'dis-' means reduction in rate, '-ation' often a process, 'sub-' means under or assist. This linguistic awareness can prevent careless errors.
专门用抽认卡来训练这些区分。考试中如果不确定，划出关键的前缀或后缀：“dis-”表示速度的降低，“-ation”常表示一个过程，“sub-”表示在下方或协助。这种语言意识可以防止粗心错误。
11. Building a Terminology Revision Schedule | 构建术语复习日程表
Divide the syllabus glossary into manageable chunks and assign a small set of terms to each day. A suggested 7-day rotating plan could be: Day 1 – Micro foundations (scarcity, factors, opportunity cost), Day 2 – Demand and supply shifters, Day 3 – Elasticity formulas, Day 4 – Market failure and intervention, Day 5 – Macro indicators, Day 6 – Policy instruments, Day 7 – International trade and exchange rates. Repeat this cycle for four weeks, adding past-paper definition questions on the weekend.
将课程大纲的词汇表分成可管理的小块，每天分配一小部分术语。建议的 7 天循环计划可以是：第一天——微观基础（稀缺性、要素、机会成本），第二天——需求与供给移动因素，第三天——弹性公式，第四天——市场失灵与干预，第五天——宏观指标，第六天——政策工具，第七天——国际贸易与汇率。将此循环重复四周，并在周末加入往年真题的定义题。
ination of saying, hearing and later writing the terms builds multi-sensory memory. Additionally, create a one-page mind map that links major terminology groups (e.g. market failure → externalities → policy → tax/subsidy → diagram) so you can visualise the entire conceptual web.
融入听觉学习：录下自己朗读定义和关键区分的音频，然后在通勤或锻炼时聆听。说、听和之后写的结合能建立多感官记忆。此外，绘制一张能将主要术语组连接起来的思维导图（如市场失灵 → 外部性 → 政策 → 税收/补贴 → 图表），使你能够可视化整个概念网络。
12. Exam Technique: Using Precise Terminology in Answers | 考试技巧：答题中精准使用术语
In Paper 2, the command words 'Define', 'Explain', 'Analyse' and 'Evaluate' require different levels of terminology use. For 'Define' (2 marks), state the exact definition and provide an example to earn the second mark. For 'Explain' (4–6 marks), embed terminology within a chain of reasoning, using connecting phrases like 'this leads to', 'consequently', 'which may then cause'. Never present an isolated definition—always apply the term to the context of the question.
在卷二中，指令词“Define”、“Explain”、“Analyse”和“Evaluate”要求不同层次的术语使用。对于“Define”（2 分），给出精确的定义并提供一个例子以获取第二分。对于“Explain”（4–6 分），将术语嵌入推理链中，使用诸如“这导致”、“因此”、“进而可能引起”等连接短语。永远不要孤零零地给出一个定义——总是将术语应用于题干的语境中。
For the highest marks in evaluation, use terms like 'opportunity cost', 'effectiveness', 'equity', 'sustainability', 'long-run versus short-run', and 'trade-off' to show judgement. A sentence such as 'While a specific tax on sugary drinks may internalise the negative externality, its regressive nature raises concerns about equity' demonstrates the precise vocabulary that examiners reward. Practise writing 10-minute paragraphs that deliberately incorporate 5–8 key terms from the topic, checking your work against the mark scheme's terminology expectations.
为了在评估中获得最高分，使用“机会成本”、“有效性”、“公平性”、“可持续性”、“长期与短期”以及“权衡”等术语来展示判断力。一个如“虽然对含糖饮料征收从量税可以将负外部性内部化，但其累退性质引发了公平性方面的关切”这样的句子，展示了考官所青睐的精准词汇。练习写 10 分钟的段落，刻意融入 5 到 8 个来自该话题的关键术语，再对照评分方案中的术语期待检查你的作业。
