欢迎参加 Year 10 爱德思经济学衔接课程。这个暑期课程旨在建立你的信心，并向你介绍在整个 IGCSE 经济课程中将会遇到的核心概念、术语和思维方式。通过完成这里的阅读和活动，你将以坚实的基础开始 Year 10 的学习，顺利应对诸如基本经济问题、市场如何运作以及政府在经济中的角色等主题。
1. Welcome to Edexcel Economics | 欢迎学习爱德思经济学
Edexcel IGCSE Economics (4EC1) is a globally recognised qualification that develops your understanding of economic theory and its application to real-world issues. The course is split into two main areas: Microeconomics and Business Economics, and Macroeconomics and the Global Economy. You will sit two examination papers at the end of Year 11, each testing a mixture of knowledge, application, analysis, and evaluation.
爱德思 IGCSE 经济学 (4EC1) 是一项全球认可的资格证书，旨在培养你对经济理论及其在现实问题中应用的理解。课程分为两个主要领域：微观经济学与商业经济学，以及宏观经济学与全球经济。你将在 Year 11 结束时参加两场考试，每场考试都综合考查知识、应用、分析和评估能力。
You do not need any prior knowledge of economics to succeed. However, summer preparation helps you become familiar with the 'economic way of thinking' – using evidence, diagrams, and logical reasoning to explain choices and policies. This bridging course will give you a head start by unpacking the big ideas that underpin the entire subject.
成功学习这门课程不需要任何经济学基础。但是，暑期预习有助于你熟悉“经济学思维方式”——用证据、图表和逻辑推理来解释选择与政策。这个衔接课程将通过剖析支撑整个学科的重要思想，让你占得先机。
2. What is Economics? The Basic Economic Problem | 什么是经济学？基本经济问题
Economics is the study of how individuals, businesses, and governments make choices to allocate scarce resources in order to satisfy unlimited wants. Because resources such as time, money, and raw materials are finite, we cannot produce everything that people desire. This tension between infinite wants and finite resources is known as the basic economic problem.
经济学研究个人、企业和政府如何做出选择来分配稀缺资源，以满足无限的需求。由于时间、金钱和原材料等资源是有限的，我们无法生产人们想要的一切。这种无限欲望与有限资源之间的矛盾被称为基本经济问题。
Every society must answer three fundamental questions: What goods and services should be produced? How should they be produced? And for whom should they be produced? These questions lead to the need for choice and allocation mechanisms, which lie at the heart of economics.
每个社会都必须回答三个基本问题：应该生产什么商品和服务？应该如何生产它们？应该为谁生产？这些问题引出了选择和分配机制的必要性，而这正是经济学的核心。
3. Scarcity, Choice and Opportunity Cost | 稀缺性、选择与机会成本
Scarcity forces us to make choices. Whenever we decide to use resources in one way, we give up the chance to use them for something else. The next best alternative that we forgo is called the opportunity cost. Understanding opportunity cost helps individuals and firms weigh trade-offs and make more rational decisions.
稀缺性迫使我们做出选择。每当我们决定以某种方式使用资源时，我们就放弃了将它们用于其他方面的机会。我们所放弃的次优选择被称为机会成本。理解机会成本有助于个人和企业权衡取舍，做出更理性的决策。
For example, if a farmer uses a field to grow wheat, the opportunity cost is the value of the corn or other crops that could have been grown instead. At a national level, spending more on healthcare means there are fewer resources available for education or defence – the opportunity cost is the most valuable public service sacrificed.
例如，如果一位农民用一块田种小麦，机会成本就是本可以种植的玉米或其他作物的价值。在国家层面，增加医疗支出意味着可用于教育或国防的资源减少——机会成本就是所牺牲的最有价值的公共服务。
4. Factors of Production | 生产要素
To produce goods and services, an economy relies on four factors of production. These are the resources that combine to create output. Economists classify them as land, labour, capital, and enterprise. Each factor earns a corresponding reward: rent, wages, interest, and profit.
为了生产商品和服务，经济体依赖四种生产要素。这些是结合起来创造产出的资源。经济学家将其分为土地、劳动力、资本和企业家才能。每种要素获得相应的报酬：地租、工资、利息和利润。
| Factor | Description | Reward |
|---|---|---|
| Land | Natural resources including surfaces, minerals, and climate | Rent |
| Labour | Human effort, both physical and mental | Wages |
| Capital | Man-made aids to production, e.g. machinery, tools, and infrastructure | Interest |
| Enterprise | The willingness to take risks and combine the other factors to innovate | Profit |
Land includes all natural resources such as oil, forests, and fisheries. Labour refers to the workforce. Capital includes machinery, tools, and buildings – anything that has been produced to help produce other goods. Enterprise is the driving force that organises the other three factors and bears business risks.
土地包括石油、森林和渔场等所有自然资源。劳动力指的是劳动人口。资本包括机器、工具和建筑物——任何为帮助生产其他商品而生产出来的物品。企业家才能是组织其他三种要素并承担商业风险的驱动力。
5. Introduction to Microeconomics and Macroeconomics | 微观经济学与宏观经济学入门
Economics is split into two main branches. Microeconomics focuses on the behaviour of individual economic agents – households, firms, and markets. It examines how prices are determined, why consumers buy certain goods, and how companies decide what to produce. Key micro topics include demand and supply, elasticity, and market structures.
经济学分为两大分支。微观经济学关注个体经济主体——家庭、企业和市场的行为。它研究价格如何决定、消费者为什么购买某些商品以及企业如何决定生产什么。关键的微观主题包括需求与供给、弹性以及市场结构。
Macroeconomics looks at the economy as a whole. It deals with aggregate measures such as gross domestic product (GDP), unemployment rates, and inflation. Macroeconomists study how government policies – fiscal policy (taxation and government spending) and monetary policy (interest rates and money supply) – can influence national economic performance.
宏观经济学将经济作为一个整体来考察。它涉及国内生产总值 (GDP)、失业率和通货膨胀等总量指标。宏观经济学家研究政府政策——财政政策（税收和政府支出）和货币政策（利率和货币供应）——如何影响国家经济表现。
6. Demand and Supply: The Price Mechanism | 需求与供给：价格机制
Demand is the quantity of a good or service that consumers are willing and able to buy at different prices over a given period. The law of demand states that, ceteris paribus (other things equal), as the price of a good rises, the quantity demanded falls. This inverse relationship is shown by a downward-sloping demand curve.
需求是在给定时期内，消费者在不同价格水平下愿意并且能够购买的商品或服务的数量。需求定律指出，在其他条件不变的情况下，随着商品价格上升，需求量下降。这种反向关系表现为一条向下倾斜的需求曲线。
Supply is the quantity that producers are willing and able to offer for sale at different prices. According to the law of supply, higher prices generally encourage firms to supply more, resulting in an upward-sloping supply curve. The intersection of demand and supply determines the equilibrium market price, a process often called the price mechanism.
供给是生产者在不同价格水平下愿意并且能够提供出售的数量。根据供给定律，较高的价格通常鼓励企业供给更多，导致供给曲线向上倾斜。需求与供给的交点决定了均衡市场价格，这一过程常被称为价格机制。
Changes in non-price factors, such as consumer income, preferences, or the cost of production, shift the entire demand or supply curve. Understanding these shifts helps economists predict how market prices and quantities will adjust to new conditions.
非价格因素的变化，如消费者收入、偏好或生产成本，会移动整条需求或供给曲线。理解这些移动有助于经济学家预测市场价格和数量如何根据新条件进行调整。
7. Elasticity: A First Look | 弹性初探
Elasticity measures how responsive quantity demanded or supplied is to changes in price, income, or the price of other goods. Price elasticity of demand (PED) is calculated as:
弹性衡量需求量或供给量对价格、收入或其他商品价格变化的反应程度。需求的价格弹性 (PED) 计算公式为：
PED = %Δ Quantity Demanded ÷ %Δ Price
If PED is greater than 1, demand is elastic – consumers are very sensitive to price changes. If PED is less than 1, demand is inelastic – quantity demanded changes little when prices fluctuate. Knowledge of elasticity helps firms set prices and governments predict tax revenue.
如果 PED 大于 1，需求富有弹性——消费者对价格变化非常敏感。如果 PED 小于 1，需求缺乏弹性——价格波动时需求量变化很小。弹性知识有助于企业设定价格，也有助于政府预测税收收入。
Price elasticity of supply (PES) operates similarly, measuring how responsive quantity supplied is to a change in price. In Year 10, you will learn how factors such as the availability of raw materials and production time affect PES.
供给的价格弹性 (PES) 作用类似，衡量供给量对价格变化的反应程度。在 Year 10，你将学习原材料的可得性和生产时间等因素如何影响 PES。
8. Market Failure and Government Intervention | 市场失灵与政府干预
Markets do not always work perfectly. Market failure occurs when the free market fails to allocate resources efficiently, leading to a loss of economic welfare. Common causes include externalities (spillover effects on third parties), public goods, information gaps, and the abuse of monopoly power.
市场并不总是完美运行。市场失灵是指自由市场未能有效配置资源，导致经济福利损失。常见原因包括外部性（对第三方的溢出效应）、公共物品、信息不对称和垄断权力的滥用。
For instance, pollution from a factory imposes a negative externality on local residents who are not compensated. In contrast, vaccinations create positive externalities for society. When markets fail, governments may intervene through taxation, subsidies, regulation, or direct provision of goods and services to improve outcomes.
例如，工厂污染给当地居民带来了负外部性，而居民并没有得到补偿。相反，疫苗接种给社会带来正外部性。当市场失灵时，政府可能通过税收、补贴、监管或直接提供商品和服务来进行干预，以改善结果。
9. Introduction to Macroeconomics: GDP, Inflation, Unemployment | 宏观经济入门：GDP、通胀、失业
Gross Domestic Product (GDP) measures the total value of goods and services produced in a country over a period, usually a year. It is a key indicator of economic growth. A rising GDP generally signals higher living standards, while a falling GDP may indicate a recession.
国内生产总值 (GDP) 衡量一个国家在一段时期内（通常为一年）生产的商品和服务的总价值。它是经济增长的关键指标。GDP 上升通常意味着生活水平提高，而 GDP 下降可能表明经济衰退。
Inflation is the sustained increase in the general price level, which reduces the purchasing power of money. Governments aim to keep inflation low and stable, commonly through monetary policy. The UK government, for example, targets an inflation rate of 2%, measured by the Consumer Prices Index (CPI).
通货膨胀是指总体价格水平的持续上涨，这会降低货币的购买力。政府通常通过货币政策力求将通胀保持在低位且稳定。例如，英国政府的目标是将以消费者价格指数 (CPI) 衡量的通胀率控制在 2%。
Unemployment represents the proportion of the labour force that is willing and able to work but cannot find a job. High unemployment wastes human resources and can lead to social problems. Macroeconomic policies often aim to promote full employment alongside stable prices.
失业代表愿意并且能够工作但找不到工作的劳动力比例。高失业率浪费人力资源，并可能导致社会问题。宏观经济政策通常旨在促进充分就业，同时保持物价稳定。
10. Global Economy and Trade | 全球经济与贸易
Countries engage in international trade to obtain goods and services they cannot produce efficiently themselves. Specialisation and the principle of comparative advantage suggest that if each nation focuses on producing what it does best, total global output increases. This is why the UK exports financial services while importing tropical fruit.
国家参与国际贸易，以获取自身无法高效生产的商品和服务。专业化和比较优势原则表明，如果每个国家专注于生产自己最擅长的产品，全球总产出就会增加。这就是为什么英国出口金融服务，同时进口热带水果。
Globalisation has deepened these links through the growth of multinational corporations, trade agreements, and digital commerce. However, it also raises challenges such as trade imbalances, protectionism (tariffs and quotas), and concerns over environmental sustainability. In your course, you will explore both the benefits and drawbacks of global economic integration.
全球化通过跨国公司的增长、贸易协定和数字商务深化了这些联系。然而，它也带来了诸如贸易失衡、保护主义（关税和配额）以及对环境可持续性的担忧等挑战。在课程中，你将探讨全球经济一体化的好处与弊端。
11. Preparing for Assessments: Command Words and Skills | 备考准备：指令词与技能
Success in Edexcel Economics depends not only on knowing facts but also on applying them appropriately using command words. Common command words include 'Define', 'Explain', 'Analyse', and 'Evaluate'. Each requires a specific response structure. For instance, an 'Evaluate' question asks you to weigh up arguments for and against before reaching a justified conclusion.
在爱德思经济学中取得成功，不仅取决于了解事实，还取决于运用指令词恰当地运用这些知识。常见的指令词包括“定义 (Define)”、“解释 (Explain)”、“分析 (Analyse)”和“评估 (Evaluate)”。每个指令词都需要特定的回答结构。例如，“评估”题要求你在得出有依据的结论之前，权衡支持和反对的论点。
Throughout Year 10, you will develop the ability to draw and interpret diagrams, handle economic data, and construct chains of reasoning. Summer practice tasks can include reading short business articles and identifying the basic economic concepts at play, such as demand changes or government policies. Building a glossary of key terms now will save you time later.
在整个 Year 10，你将培养绘制和解释图表、处理经济数据以及构建推理链条的能力。暑期练习任务可以包括阅读简短的商业文章，并找出其中运用的基本经济概念，例如需求变化或政府政策。现在建立一个关键术语词汇表，以后会节省大量时间。
12. Summer Bridging Tasks and Resources | 暑期衔接任务与资源
To make the most of your summer, try to complete a few light-touch activities. Keep a 'choice diary' for one week: note every decision you make (what to eat, how to spend your time) and identify the opportunity cost. Watch a news segment on a current economic issue and try to classify it as micro or macro. Sketch a basic demand and supply diagram for a product of your choice and label the equilibrium.
为了充分利用暑期，可以完成一些轻松的活动。写一周的“选择日记”：记下你做出的每一个决定（吃什么、如何安排时间），并找出机会成本。观看一个关于当前经济问题的新闻片段，尝试将其归类为微观还是宏观。为你选择的一种产品画一个基本的供需图，并标出均衡点。
Recommended digital resources include the Economics section on BBC Bitesize, the Bank of England’s education pages, and TED-Ed economics videos. Reading a beginner-friendly book such as 'The Undercover Economist' can also deepen your curiosity. Remember, the key is not to memorise everything but to start noticing economic choices all around you.
推荐的数字资源包括 BBC Bitesize 的经济学板块、英格兰银行的教育页面以及 TED-Ed 经济学视频。阅读一本适合初学者的书，比如《卧底经济学》，也能加深你的好奇心。请记住，关键不是记住所有内容，而是开始关注你身边的经济选择。
