剑桥 IGCSE 经济 (0455) 为学生打下扎实的经济学理论基础，涵盖术语、原理和应用。Year 11 学生将学习完整的课程大纲，探讨个人、企业和政府在稀缺条件下如何作出选择。本文将逐章解析大纲核心内容，帮助你有条理地复习，轻松应对考试。
1. The Basic Economic Problem | 基本经济问题
The fundamental economic problem is scarcity: unlimited wants versus limited resources. This creates the need to make choices, and every choice involves an opportunity cost – the next best alternative forgone. The syllabus also introduces the factors of production: land, labour, capital, and enterprise.
经济学的基本问题是稀缺性：无限的欲望与有限的资源之间的矛盾。这就迫使人们做出选择，而每一个选择都涉及机会成本——即放弃的次优选择。课程还介绍了生产要素：土地、劳动力、资本和企业家才能。
Students must understand how goods and services are classified (free goods vs. economic goods, consumer vs. capital goods) and how a production possibility curve (PPC) illustrates opportunity cost, efficiency, and economic growth. A shift of the PPC outward indicates an increase in productive capacity.
学生必须理解商品和服务的分类（免费商品与经济商品、消费品与资本品），以及生产可能性曲线 (PPC) 如何展示机会成本、效率与经济增长。生产可能性曲线向外移动表示生产能力的提升。
2. Allocation of Resources | 资源配置
This section covers how market systems, mixed economies, and planned economies answer the three key questions: what to produce, how to produce, and for whom to produce. The price mechanism plays a central role in allocating resources in a market economy, balancing demand and supply.
这一部分介绍市场体制、混合经济和计划经济如何回答三大基本问题：生产什么、如何生产、为谁生产。价格机制在市场经济中负责配置资源，通过供需平衡实现调节。
Demand is defined as the quantity consumers are willing and able to buy at a given price. The law of demand states that as price falls, quantity demanded rises (ceteris paribus). Supply refers to the quantity producers are willing and able to sell; the law of supply shows a direct relationship between price and quantity supplied. Market equilibrium occurs where demand equals supply. Students also examine price elasticity of demand (PED), price elasticity of supply (PES), and income elasticity (YED), including their determinants and impact on revenue.
需求定义为消费者在特定价格下愿意且能够购买的数量。需求定律指出，价格下降时需求量上升（其他因素不变）。供给指生产者愿意且能够出售的数量；供给定律显示价格与供给量呈正相关。市场均衡出现在需求等于供给之时。学生还会学习需求价格弹性 (PED)、供给价格弹性 (PES) 和收入弹性 (YED)，包括其决定因素及对收益的影响。
3. Microeconomic Decision Makers | 微观经济决策者
Households, firms, and governments are the main decision-making units in an economy. The syllabus examines spending, saving, and borrowing by households, as well as the objectives and behaviour of firms, including costs, revenues, and profit maximisation.
家庭、企业和政府是经济中的主要决策单位。课程分析了家庭的支出、储蓄与借贷行为，以及企业的目标与行为，包括成本、收益和利润最大化。
Students learn to calculate total cost, average cost, total revenue, and average revenue. They also explore how the size and structure of firms affect their efficiency. Economies and diseconomies of scale explain why larger firms can have cost advantages up to a point, after which average costs may rise. Market structure is introduced, distinguishing between competitive and non-competitive markets.
学生需要学会计算总成本、平均成本、总收益和平均收益。他们还将探讨企业规模和结构如何影响效率。规模经济与规模不经济解释了为什么大企业在某一阶段具有成本优势，但超过一定规模后平均成本可能上升。课程引入市场结构，区分竞争市场与非竞争市场。
4. Government and the Macroeconomy | 政府与宏观经济
Macroeconomic objectives include economic growth, full employment, price stability, and a sustainable balance of payments. The syllabus explains how economic growth is measured by GDP, and why governments aim to maintain low inflation and low unemployment.
宏观经济目标包括经济增长、充分就业、物价稳定和可持续的国际收支平衡。课程解释了如何用 GDP 衡量经济增长，以及政府为何要维持低通胀和低失业率。
Students explore the causes and consequences of inflation, unemployment, and economic recessions. They also examine the main government policies: fiscal policy (taxation and government spending), monetary policy (interest rates and money supply), and supply-side policies. The circular flow of income illustrates the interdependencies between households, firms, government, and the foreign sector.
学生将探讨通胀、失业和经济衰退的原因与后果。他们还将学习主要的政府政策：财政政策（税收与政府支出）、货币政策（利率与货币供给）以及供给侧政策。收入循环流动图展示了家庭、企业、政府和国外部门之间的相互依赖关系。
5. Economic Development | 经济发展
Living standards differ widely across countries. This syllabus topic examines indicators of development such as GDP per capita, Human Development Index (HDI), literacy rate, and life expectancy. It explains why some countries remain poor, while others grow rapidly.
各国生活水平差异显著。本主题探讨了发展指标，如人均 GDP、人类发展指数 (HDI)、识字率和预期寿命，解释了为何一些国家依然贫困而另一些国家增长迅速。
Students analyse the causes of poverty, the poverty cycle, and the role of domestic policies and international aid in promoting development. They also discuss the impact of population growth on development, including the dependency ratio and its implications for resource use and government services.
学生分析贫困的原因、贫困循环，以及国内政策和国际援助在促进发展中的作用。他们还会讨论人口增长对发展的影响，包括抚养比及其对资源利用和政府服务的含义。
6. International Trade and Globalisation | 国际贸易与全球化
International trade enables specialisation and exchange, based on comparative advantage. The syllabus covers free trade, protectionism (tariffs, quotas, subsidies), and their effects on domestic and foreign stakeholders. Students learn how exchange rates are determined and how currency fluctuations affect trade flows.
国际分工与交换的基础是比较优势。课程涵盖自由贸易与保护主义（关税、配额、补贴）及其对国内外利益相关者的影响。学生将学习汇率如何决定，以及货币波动如何影响贸易流。
Globalisation refers to the increasing integration of economies through trade, investment, and technology. The syllabus considers both the benefits (increased choice, lower prices, technology transfer) and the drawbacks (inequality, environmental damage, loss of cultural identity). Students should be able to evaluate the impact of multinational corporations (MNCs) on host countries.
全球化是指各国经济通过贸易、投资和技术日益融合的过程。课程既考虑了好处（增加选择、降低价格、技术转移），也考虑了弊端（不平等、环境破坏、文化认同丧失）。学生需要能够评价跨国公司 (MNCs) 对东道国的影响。
7. The Role of Financial Markets | 金融市场的作用
Financial markets channel savings into investment, providing a crucial link between lenders and borrowers. The syllabus examines the functions of stock exchanges, banks, and other financial institutions. Students explore how interest rates influence saving, borrowing, and investment decisions.
金融市场将储蓄转化为投资，成为借贷双方的重要纽带。课程考察了证券交易所、银行及其他金融机构的职能。学生将探讨利率如何影响储蓄、借贷和投资决策。
Understanding central banks is key: they manage monetary policy, regulate commercial banks, and ensure financial stability. The syllabus also touches on the foreign exchange market, where currencies are traded and exchange rates determined.
理解中央银行的作用至关重要：它们管理货币政策、监管商业银行并维护金融稳定。课程还涉及外汇市场，即货币交易和汇率决定的市场。
8. Labour Markets and Wage Determination | 劳动力市场与工资决定
Workers supply labour in exchange for wages. The supply of labour depends on factors such as population size, non-monetary benefits, and barriers to entry. Demand for labour is derived from the demand for goods and services. The syllabus analyses how equilibrium wage rates are determined in different labour markets.
工人提供劳动力以换取工资。劳动力供给取决于人口规模、非金钱福利和准入门槛等因素。劳动力需求派生自对商品和服务的需求。课程分析了不同劳动力市场中均衡工资率的决定。
Students examine why wage differentials exist – differences in skills, qualifications, working conditions, and trade union power. The role of trade unions in collective bargaining and their impact on wage levels and employment is also explored. Government intervention in labour markets, such as minimum wage laws, is evaluated.
学生将研究工资差别存在的原因——技能、资质、工作条件和工会力量的差异。课程还探讨了工会在集体谈判中的作用及其对工资水平和就业的影响。政府干预劳动力市场（如最低工资法）也会被评估。
9. Market Failure and Government Intervention | 市场失灵与政府干预
Markets do not always lead to efficient outcomes. Market failure arises from externalities, public goods, information gaps, and monopoly power. Students learn to identify positive and negative externalities in production and consumption, using diagrams to illustrate social optimum versus private optimum.
市场并非总能带来有效结果。市场失灵源于外部性、公共物品、信息不对称和垄断力量。学生将学会识别生产和消费中的正外部性与负外部性，并用图表说明社会最优与私人最优的区别。
Possible government responses include taxation, subsidies, regulation, and direct provision. Each policy has advantages and limitations; students are expected to evaluate their effectiveness in correcting different types of market failure. Cost-benefit analysis is introduced as a decision-making tool for public projects.
政府可能的应对措施包括征税、补贴、监管和直接提供。每种政策都有其优势和局限；学生需要评价它们在纠正各类市场失灵时的有效性。课程还引入成本效益分析作为公共项目的决策工具。
10. International Economic Organisations | 国际经济组织
International bodies such as the World Trade Organization (WTO), International Monetary Fund (IMF), and World Bank influence the global economy. The syllabus explains their roles in promoting trade liberalisation, financial stability, and development assistance.
世界贸易组织 (WTO)、国际货币基金组织 (IMF) 和世界银行等国际机构影响着全球经济。课程解释了它们在推动贸易自由化、金融稳定和发展援助方面的作用。
Students evaluate the effectiveness of these organisations and consider criticisms, such as conditionality attached to IMF loans or the unequal bargaining power within the WTO. The syllabus also covers free trade areas and customs unions, using examples like the European Union (EU).
学生评价这些组织的成效，并讨论批评意见，例如 IMF 贷款的附加条件或 WTO 内部不平等的谈判权。课程还涵盖自由贸易区和关税同盟，以欧盟 (EU) 等为例。
11. Assessment Structure and Exam Preparation | 考试结构与备考指南
Cambridge IGCSE Economics (0455) is assessed through two papers. Paper 1 consists of 30 multiple-choice questions, testing knowledge across the entire syllabus. Paper 2 is a structured written paper requiring longer answers, data analysis, and essay-style evaluation.
剑桥 IGCSE 经济 (0455) 通过两份试卷考核。Paper 1 包括 30 道选择题，覆盖全部大纲知识点。Paper 2 是结构化书面试卷，要求撰写较长答案、数据分析以及论述式评价。
To excel, students must master definitions, diagrams, and chains of reasoning. Command words like “Define”, “Explain”, “Analyse”, and “Evaluate” signal the depth required. Practice with past papers builds familiarity with question styles and time management. Consistent review of key concepts and current economic news strengthens application skills.
要取得高分，学生必须掌握定义、图表和推理链条。指令词如“定义”、“解释”、“分析”、“评估”暗示了答题所需深度。通过历年真题练习可以熟悉题型并锻炼时间管理。持续复习核心概念并关注经济时事有助于增强应用能力。
12. Common Pitfalls and How to Avoid Them | 常见误区与应对策略
A common mistake is confusing movements along the demand curve with shifts of the demand curve. A price change causes a movement along the curve, while changes in non-price factors shift the entire curve. Another frequent error is treating correlation as causation when interpreting data.
常见误区是将需求曲线上的移动与需求曲线的移动混为一谈。价格变动导致沿曲线移动，而非价格因素变化则使整条曲线平移。另一个常见错误是在解读数据时将相关关系误认为因果关系。
Students also lose marks by failing to label axes correctly on diagrams or by omitting the backward-bending nature of certain curves where required. In evaluation questions, simply listing pros and cons without a reasoned conclusion does not score highly. Practising structured essay plans and focusing on “it depends on…” reasoning can significantly improve results.
学生还可能因图表中坐标轴标注有误或未按要求画出某些曲线的向后弯曲部分而失分。在评估题中，简单罗列利弊而没有合理结论无法获得高分。练习构建论述框架并注重“取决于……”的推理方式可以显著提高成绩。
