1. Why Study Economics in Year 7? | 为什么要在七年级学习经济学？
Economics is not just about money – it is about how people, businesses, and governments make decisions every day. In Year 7, you begin to explore why some things are expensive while others are cheap, why we cannot have everything we want, and how trade makes our lives better. Understanding economics helps you become a more informed citizen and a smarter decision-maker.
经济学并不只与金钱有关——它关乎个人、企业和政府如何每天做出决策。在七年级，你开始探索为什么有些东西贵而有些便宜，为什么我们不能拥有所有想要的东西，以及贸易如何让我们的生活更美好。理解经济学能让你成为更有见识的公民和更明智的决策者。
Studying economics from Year 7 also prepares you for the OCR GCSE Economics course, where you will dive deeper into topics like markets, international trade, and government policy. Even if you do not pursue economics as a career, the analytical skills you gain – such as evaluating costs and benefits, reading data, and thinking critically – will support you in many other subjects and in real life.
从七年级开始学习经济学也为 OCR GCSE 经济学课程做好准备，届时你将更深入地探讨市场、国际贸易和政府政策等主题。即便你不将经济学作为职业方向，你所获得的分析技能——例如评估成本与收益、解读数据以及批判性思维——也会在许多其他学科和现实生活中给予你支持。
2. What Is Economics? | 经济学是什么？
Economics is the study of how individuals, businesses, and societies choose to use their limited resources to satisfy their unlimited wants. It is a social science that combines elements of mathematics, psychology, history, and politics to explain human behaviour in the face of scarcity.
经济学研究个人、企业和社会如何选择利用有限的资源来满足无限的欲望。它是一门社会科学，融合了数学、心理学、历史和政治学的元素，用于解释在稀缺性面前的人类行为。
Economists divide the subject into two main branches: microeconomics and macroeconomics. Microeconomics focuses on small-scale decisions, such as how a household divides its income between food and entertainment, or why a cinema might lower ticket prices on a weekday. Macroeconomics looks at the big picture, dealing with issues like national unemployment, inflation, and economic growth. Both branches help us understand the world from different perspectives.
经济学家将该学科分为两个主要分支：微观经济学和宏观经济学。微观经济学关注小规模决策，例如一个家庭如何在食物和娱乐之间分配收入，或者电影院为何会在工作日降低票价。宏观经济学则着眼于全局，处理国家失业、通货膨胀和经济增长等问题。两个分支帮助我们以不同视角理解世界。
3. The Basic Economic Problem: Scarcity | 基本经济问题：稀缺性
At the heart of economics lies the basic economic problem: we have limited resources but unlimited wants. No matter how wealthy a country or a person becomes, there will never be enough goods, services, or time to satisfy every desire. This universal condition is called scarcity.
经济学的核心是基本经济问题：我们拥有有限的资源，却有着无限的欲望。无论一个国家或个人多么富有，永远不会有足够的商品、服务或时间来满足每一个愿望。这种普遍状况被称为稀缺性。
Scarcity forces us to make choices. For example, with your weekly pocket money you might have to decide between buying a comic book, saving for a video game, or going to the cinema. Because you cannot do all three at once, you must choose how to allocate your limited funds. The same principle applies to governments deciding how to spend tax revenue on healthcare, education, or defence.
稀缺性迫使我们做出选择。例如，用每周的零花钱，你可能必须决定是买一本漫画书、存钱买个电子游戏，还是去看电影。因为你无法同时做这三件事，你必须选择如何分配有限的资金。同样的原则也适用于政府决定如何将税收用于医疗、教育或国防。
4. Choice and Opportunity Cost | 选择与机会成本
Every choice involves giving up the next best alternative. The value of that forgone alternative is known as the opportunity cost. When you decide to spend an hour playing football instead of studying, the opportunity cost is the improvement in your grades that you could have achieved during that hour.
每一个选择都涉及放弃次优替代方案。那个被放弃的方案的价值被称为机会成本。当你决定花一小时踢足球而不是学习时，机会成本就是你本可以在那一小时获得的成绩提升。
Opportunity Cost = Value of the Next Best Alternative Foregone
机会成本 = 所放弃的最佳替代方案的价值
To calculate opportunity cost, you need to identify what you are sacrificing. If a student has £10 and must choose between a cinema ticket (£10) and a music streaming subscription (£10), the opportunity cost of buying the cinema ticket is the enjoyment from the subscription that is given up. Understanding opportunity cost helps you make more rational decisions because you become aware of what you truly lose when you choose one option over another.
要计算机会成本，你需要明确自己放弃了什么。如果一个学生有10英镑，必须在电影票（10英镑）和音乐流媒体订阅（10英镑）之间选择，购买电影票的机会成本就是放弃的订阅所带来的乐趣。理解机会成本有助于你做出更理性的决策，因为你会意识到选择一项而放弃另一项时真正失去了什么。
5. Economic Agents: Consumers, Producers, and Government | 经济主体：消费者、生产者和政府
An economy is made up of different economic agents, each with its own objectives. Consumers aim to maximise their satisfaction or utility from the goods and services they buy with their limited income. For example, you as a consumer might compare prices and quality before buying a pair of trainers.
经济由不同的经济主体构成，每个主体都有自己的目标。消费者旨在用其有限的收入从购买的商品和服务中获得最大满足感或效用。例如，作为消费者，你可能会在购买一双运动鞋前比较价格和质量。
Producers, such as firms and entrepreneurs, seek to maximise profits by producing goods and services that consumers are willing to buy. They make decisions about what to produce, how much to produce, and which production methods to use. A bakery, for instance, decides whether to make more bread or more cakes based on customer demand.
生产者，如企业和企业家，通过生产消费者愿意购买的商品和服务来追求利润最大化。他们对生产什么、生产多少以及使用何种生产方法做出决策。例如，面包店会根据客户需求决定是多做面包还是多做蛋糕。
The government acts as both a regulator and a provider. It aims to improve the overall welfare of society by providing public goods like street lighting, maintaining law and order, and intervening in markets when they fail. Governments also redistribute income through taxes and benefits to reduce inequality.
政府既是监管者又是提供者。它旨在通过提供路灯等公共物品、维护法律和秩序以及在市场失灵时进行干预，来提高社会整体福利。政府还通过税收和福利重新分配收入以减少不平等。
6. The Role of Markets | 市场的作用
A market is any place – physical or virtual – where buyers and sellers come together to exchange goods and services. Markets can be as local as a farmers’ market or as global as the market for crude oil. The key function of a market is to determine prices through the forces of supply and demand.
市场是任何买方和卖方聚集在一起交换商品和服务的场所——可以是实体的，也可以是虚拟的。市场可以小至农贸市场，也可以大至全球原油市场。市场的核心功能是通过供给和需求的力量决定价格。
Prices act as signals in a market economy. If a product becomes very popular, its price tends to rise, signalling producers to supply more. Conversely, if people stop buying a product, its price will likely fall, prompting producers to reduce output. This self-regulating mechanism helps allocate resources efficiently without any central planner.
价格在市场经济中充当信号。如果某种产品变得非常受欢迎，其价格往往会上涨，这向生产者发出增加供应的信号。相反，如果人们停止购买某种产品，其价格可能会下跌，促使生产者减少产量。这种自我调节机制无需任何中央计划者就能高效地配置资源。
7. Supply and Demand: The Invisible Hand | 供给与需求：看不见的手
The law of demand states that, all other things being equal, as the price of a good rises, the quantity demanded falls, and vice versa. This happens because consumers usually seek cheaper alternatives or buy less when items become more expensive.
需求定律指出，在其他条件不变的情况下，商品价格上升，需求量下降，反之亦然。这是因为当商品变得更贵时，消费者通常会寻找更便宜的替代品或减少购买。
The law of supply states that, all other things being equal, as the price of a good rises, the quantity supplied rises. Higher prices give producers a greater incentive to produce more because they can earn higher revenues and profits.
供给定律指出，在其他条件不变的情况下，商品价格上升，供给量增加。较高的价格给予生产者更大的激励去增加生产，因为他们可以获得更高的收入和利润。
When supply and demand interact, they determine the market equilibrium price – the point where the amount consumers want to buy exactly equals the amount producers want to sell. Adam Smith famously described this process as the “invisible hand” that guides resources to their most valued uses without government direction.
当供给和需求相互作用时，它们决定了市场均衡价格——即消费者愿意购买的数量恰好等于生产者愿意出售的数量的点位。亚当·斯密曾形象地将这一过程描述为”看不见的手”，它无需政府指令就能引导资源流向最有价值的用途。
8. Production and Factors of Production | 生产与生产要素
Production is the process of turning inputs into outputs – goods and services that people want. To produce anything, an economy relies on four factors of production: land, labour, capital, and enterprise.
生产是将投入转化为产出——人们想要的商品和服务——的过程。要生产任何东西，经济体都依赖于四种生产要素：土地、劳动力、资本和企业家才能。
Land refers to all natural resources, such as forests, minerals, water, and agricultural land. Labour is the human effort – both physical and mental – used in production. Capital includes man-made goods used to produce other goods, like machinery, factories, and computers. Enterprise is the ability to combine the other three factors, take risks, and innovate, often performed by entrepreneurs.
土地指所有自然资源，如森林、矿产、水和农田。劳动力是生产中使用的人力——包括体力和脑力。资本包括用于生产其他商品的人造物品，如机器、工厂和电脑。企业家才能是指将其他三种要素结合起来、承担风险并进行创新的能力，这通常由企业家来执行。
Each factor earns a reward: land earns rent, labour earns wages, capital earns interest, and enterprise earns profit. Understanding these factors helps you grasp how wealth is created and shared in an economy.
每种要素都获得回报：土地获得地租，劳动力获得工资，资本获得利息，企业家才能获得利润。理解这些要素有助于你把握经济中财富是如何创造和分配的。
9. Money and Its Functions | 货币及其功能
Before money existed, people used barter – directly swapping one good for another. Barter requires a double coincidence of wants, meaning both parties must want what the other offers. Money solves this problem by serving as a generally accepted medium of exchange.
在货币出现之前，人们使用物物交换——直接用一种商品交换另一种商品。物物交换要求需求的双重巧合，即双方都必须想要对方提供的物品。货币通过充当普遍接受的交换媒介解决了这一问题。
Money has three main functions. First, it is a medium of exchange, allowing you to buy goods and services without barter. Second, it is a unit of account, providing a standard measure for prices and debts (for example, a cinema ticket costing £10). Third, it is a store of value, enabling you to save purchasing power for future use because money can be held and spent later.
货币具有三个主要功能。第一，它是交换媒介，让你无需物物交换就能购买商品和服务。第二，它是计量单位，为价格和债务提供标准度量（例如，一张电影票售价10英镑）。第三，它是价值贮藏手段，让你能将购买力储存起来以备将来使用，因为货币可以持有并稍后消费。
Modern economies use fiat money – currency that has value because the government decrees it as legal tender. Trust in the stability of that money is essential for it to function effectively.
现代经济体使用法定货币——因其政府规定其为法定偿还手段而具有价值的货币。对货币稳定性的信任是其有效运作的关键。
10. Different Economic Systems | 不同的经济体制
Societies organise their economies in different ways. The three main types are market economies, command economies, and mixed economies. Each handles the fundamental questions of what to produce, how to produce, and for whom to produce differently.
社会以不同方式组织其经济。三种主要类型是市场经济、指令经济和混合经济。它们处理生产什么、如何生产以及为谁生产这些基本问题的方式各不相同。
In a pure market economy, decisions are made entirely by private individuals and firms based on prices and profit motives. There is minimal government interference. In contrast, a command economy has the government owning most resources and making all major economic decisions, as seen in historical examples like the former Soviet Union.
在纯粹市场经济中，决策完全由私人和企业基于价格和利润动机做出。政府干预极少。相反，指令经济中政府拥有大部分资源并做出所有重大经济决策，历史上的苏联等实例即是如此。
However, nearly all modern economies, including the UK, are mixed economies. They combine elements of market freedom with government intervention – for instance, allowing private businesses to operate while the government provides healthcare and education. This balance attempts to harness the efficiency of markets while addressing issues like inequality and unemployment.
然而，包括英国在内的几乎所有现代经济体都是混合经济。它们将市场自由元素与政府干预结合起来——例如，允许私营企业运营的同时政府提供医疗和教育。这种平衡试图利用市场的效率，同时解决不平等和失业等问题。
11. Making Decisions as an Economist | 像经济学家一样做决策
Economists use a particular way of thinking that focuses on trade-offs, marginal analysis, and incentives. When facing a decision, an economist asks: What are the additional benefits and costs of doing one more unit? This is called marginal thinking.
经济学家使用一种特定的思维方式，侧重于权衡、边际分析和激励。当面对决策时，经济学家会问：再多做一单位的额外收益和成本是什么？这被称为边际思维。
For example, a cinema manager might consider whether to stay open for one extra hour. The marginal benefit would be the extra ticket sales from that hour; the marginal cost would be the electricity and staff wages. If the marginal benefit exceeds the marginal cost, it is rational to stay open longer.
例如，电影院经理可能会考虑是否要多营业一小时。边际收益是那一小时额外售票的收入；边际成本是电费和员工工资。如果边际收益超过边际成本，那么延长营业时间就是理性的。
Economists also recognise that people respond to incentives. A subsidy for electric cars encourages more people to buy them, while a tax on sugary drinks discourages consumption. By predicting how people will react to different incentives, policies can be designed to achieve desired outcomes, such as reducing pollution or improving public health.
经济学家也认识到人们会对激励做出反应。对电动汽车的补贴鼓励更多人购买，而对含糖饮料征税则抑制消费。通过预测人们如何对不同的激励做出反应，可以设计政策以实现预期结果，如减少污染或改善公共健康。
12. Tips for Succeeding in OCR Economics | 学好 OCR 经济学的技巧
To get the most out of your Year 7 economics lessons, start by building a strong vocabulary. Keep a glossary of key terms like scarcity, opportunity cost, demand, and supply, and review them regularly. Understanding the language of economics is half the battle.
要想从七年级经济学课堂中充分获益，首先要建立扎实的词汇基础。用一个词汇表记录稀缺性、机会成本、需求、供给等关键术语，并定期复习。理解经济学的语言是成功的一半。
Next, connect what you learn to real-world events. Read simplified news articles or watch short videos about the economy, and try to identify the concepts you have studied in class. For example, when you hear about petrol prices rising, think about supply and demand factors that might be causing it.
接下来，将所学知识与现实世界事件联系起来。阅读简化的新闻文章或观看关于经济的短片，尝试找出你在课堂上学过的概念。例如，当你听说汽油价格上涨时，想一想可能是哪些供给和需求因素造成了这一现象。
Finally, practise structured writing. OCR exam questions often ask you to explain or evaluate. Get into the habit of explaining your reasoning step by step and using economic terminology accurately. Discuss ideas with classmates and test each other – teaching someone else is one of the best ways to solidify your own understanding.
最后，练习结构化写作。OCR 考试题目常常要求你解释或评估。养成逐步解释你的推理并准确使用经济学术语的习惯。与同学讨论观点并互相测试——教别人是巩固自身理解的最佳方法之一。
