Welcome to your first year of secondary school economics! This guide has been designed to help you transition smoothly into the key ideas of the subject, aligned with the AQA framework for Key Stage 3. You will explore how the world of scarcity, choice, and trade works, and build a foundation that will take you all the way to GCSE and beyond. Let us dive into the core principles that shape every economic decision you make, from your pocket money to the global marketplace.

欢迎开启中学一年级经济学的学习之旅！本指南旨在帮助你平稳过渡，掌握与AQA关键阶段3框架一致的核心概念。你将探索稀缺、选择和交易的世界如何运转，并为未来的GCSE及更高阶段打下坚实基础。现在，让我们深入探讨那些塑造每一次经济决策的基本原则——从你的零花钱到全球市场。

1. What is Economics? | 什么是经济学？

Economics is the social science that studies how people, businesses, and governments allocate limited resources to satisfy their unlimited wants. It is not just about money; it is about making choices in a world where we cannot have everything.

经济学是一门社会科学，研究个人、企业和政府如何分配有限的资源以满足无限的欲望。它不仅仅关乎金钱，更关乎我们在无法拥有一切的世界里如何做出选择。

The subject is divided into two main branches. Microeconomics focuses on individual decision-making, such as how a household budgets or how a firm sets prices. Macroeconomics looks at the big picture, including national income, unemployment, and trade between countries.

这门学科分为两大主要分支。微观经济学关注个体决策，比如一个家庭如何编制预算或一家企业如何定价。宏观经济学则着眼于整体图景，包括国民收入、失业率以及国家间的贸易。

In your daily life, you already use economic thinking when you decide how to spend your time, whether to save your allowance, or why some items cost more than others. Studying economics will help you understand these puzzles and improve your decision-making.

在日常生活中，当你决定如何分配时间、是否储蓄零花钱，或者思考为什么某些商品更贵时，你已经在运用经济学思维了。学习经济学会帮助你理解这些谜题，并改善你的决策能力。

2. The Basic Economic Problem | 基本经济问题

The fundamental economic problem is that resources are limited, but human wants are unlimited. This mismatch forces individuals and societies to make choices about what to produce, how to produce it, and for whom to produce it.

基本经济问题在于：资源是有限的，而人类的欲望却是无限的。这种不匹配迫使个人和社会必须选择生产什么、如何生产以及为谁生产。

Even the wealthiest nations face scarcity. Land, labour, capital, and time are never enough to satisfy everyone’s desires for food, housing, entertainment, and more. Economists call this condition ‘scarcity’, and it is the very reason economics exists as a discipline.

即使最富裕的国家也面临稀缺性。土地、劳动力、资本和时间永远不足以满足每个人对食物、住房、娱乐等方面的渴望。经济学家将这种情况称为’稀缺性’，而这正是经济学作为一门学科存在的根本原因。

Because scarcity cannot be eliminated, every community needs a system to decide how to allocate resources. Markets, governments, and traditions all play a part in answering the three basic questions of production.

由于稀缺性无法消除，每个社会都需要一套系统来决定如何配置资源。市场、政府和传统在回答三个基本生产问题上都发挥着作用。

3. Scarcity and Choice | 稀缺与选择

Scarcity means that we always have to make choices. When you choose one option, you give up another. This concept applies to individuals, firms, and governments alike. For example, a student who spends an hour gaming gives up the chance to study or exercise.

稀缺意味着我们总是必须做出选择。当你选择一个选项时，你就放弃了另一个。这个概念适用于个人、企业和政府。例如，一个学生花一小时玩游戏，就放弃了学习或锻炼的机会。

Choices are guided by priorities and constraints. Your pocket money may only stretch to one new video game or two cinema trips. You must weigh up the satisfaction each would bring before deciding. Economists call this ranking of preferences ‘utility’.

选择受到优先事项和约束条件的引导。你的零花钱可能只够买一款新电子游戏或看两次电影。你必须权衡每种选择带来的满足感再决定。经济学家把这种偏好排序称为’效用’。

Resource / 资源	Scarce Choice / 稀缺选择
Time	Study for a test vs. play football
Money	Buy a new book vs. save for a bike
Natural resources	Use land for crops vs. build houses

This table shows how scarcity forces trade-offs at every level. Recognising these constraints helps us allocate our resources more wisely and understand why others make different choices.

这个表格展示了稀缺如何在各个层面迫使人们进行权衡。认识到这些约束能帮助我们更明智地分配资源，并理解为什么他人会做出不同的选择。

4. Opportunity Cost | 机会成本

Opportunity cost is the value of the next best alternative that you give up when you make a choice. It is one of the most important concepts in economics because it reminds us that every decision has a true cost beyond money.

机会成本是指你在做出选择时放弃的次优选项的价值。这是经济学中最重要的概念之一，因为它提醒我们，每个决策除了金钱之外还有一个真实的成本。

For instance, if a government spends £10 million on a new hospital, the opportunity cost might be the school or road it could have built instead. For you, the opportunity cost of reading this guide is the time you could have spent scrolling through social media.

例如，如果政府花费1000万英镑建造一所新医院，其机会成本可能是本可以建造的学校或道路。对你来说，阅读本指南的机会成本就是你本可以花在浏览社交媒体上的时间。

Calculating opportunity cost helps us see the hidden trade-offs in our decisions. Although it is not always written down in pound signs, it is just as real. Smart decision-makers always ask, ‘What am I giving up by choosing this?’

计算机会成本有助于我们发现决策中隐藏的权衡。尽管它不一定以英镑符号标明，但它同样真实。聪明的决策者总会问自己：’选择这个，我放弃了什么？’

5. Factors of Production | 生产要素

To produce any good or service, we need inputs known as the factors of production. There are four classic types: land, labour, capital, and enterprise. Each one earns a different type of reward.

要生产任何商品或服务，我们需要投入被称为生产要素的资源。经典分类有四种：土地、劳动力、资本和企业家才能。每种要素获得不同类型的报酬。

Land includes all natural resources like minerals, forests, and water. Its reward is rent.
Labour is the human effort, both physical and mental. Its reward is wages.
Capital refers to man-made tools, machinery, and buildings used to make other goods. Its reward is interest.
Enterprise is the ability to combine the other three factors and take risks. Its reward is profit.

土地包括所有自然资源，如矿产、森林和水。其报酬是地租。
劳动力指人类的体力和脑力付出。其报酬是工资。
资本指用于制造其他商品的人造工具、机器和建筑物。其报酬是利息。
企业家才能是指组合其他三种要素并承担风险的能力。其报酬是利润。

In Year 7, think of these factors whenever you see a finished product. A pizza, for example, uses land (wheat, tomatoes), labour (chef, delivery driver), capital (oven, scooter), and enterprise (the pizza shop owner’s business idea).

在七年级阶段，每当你看见一个成品时，都要想想这些生产要素。例如，一个比萨饼使用了土地（小麦、番茄）、劳动力（厨师、送餐员）、资本（烤箱、摩托车）和企业家才能（比萨店老板的商业创意）。

6. Needs and Wants | 需要与欲望

Economists draw a clear line between needs and wants. Needs are essential goods and services required for survival, such as food, clean water, shelter, and clothing. Wants are the extras that make life more comfortable and enjoyable, like designer trainers or the latest smartphone.

经济学家明确区分需要和欲望。需要是生存所必需的基本商品和服务，如食物、洁净的水、住所和衣物。欲望是让生活更舒适和愉快的东西，比如名牌运动鞋或最新款的智能手机。

Because resources are scarce, societies must decide how to meet basic needs before satisfying wants. In some countries, fulfilling all needs remains a daily challenge, while in others, advertising often blurs the line, making people believe wants are needs.

由于资源稀缺，社会必须决定如何先满足基本需要，然后再满足欲望。在一些国家，满足所有需要依然是日常挑战，而在另一些国家，广告常常模糊界限，让人们以为欲望就是需要。

Understanding this distinction helps you become a savvy consumer. Ask yourself: ‘Do I need this, or do I just want it?’ This simple question can improve your budgeting and reduce unnecessary spending.

理解这一区别有助于你成为精明的消费者。问问自己：’我需要这个，还是只是想要它？’这个简单的问题可以改进你的预算规划，减少不必要的支出。

7. Producers and Consumers | 生产者与消费者

Economies are made up of two key groups: producers and consumers. Producers are individuals or firms that create goods and provide services. Consumers are people who buy and use those goods and services to satisfy their needs and wants.

经济体由两大关键群体组成：生产者和消费者。生产者是制造商品和提供服务的个人或企业。消费者是购买并使用这些商品和服务以满足需要和欲望的人。

Producers aim to make a profit by combining the factors of production efficiently. They decide what quantities to supply based on consumer demand. In this way, the interaction between producers and consumers determines what is available in the market.

生产者通过高效组合生产要素来谋取利润。他们根据消费者需求决定供给量。这样，生产者与消费者之间的互动决定了市场上能买到什么。

In Year 7, you will learn that businesses range from small local sellers like a corner shop to giant multinational corporations. Everything from the chair you sit on to the app you use for homework involves a chain of producers and consumers working together in the economy.

在七年级阶段，你会学到企业类型多样，从街角小店这样的小型本地商家，到大型跨国公司。从你坐着的椅子到你用于做作业的应用程序，都涉及生产者与消费者在经济中协同工作的链条。

8. Supply and Demand (Introduction) | 供给与需求（入门）

Supply and demand are the forces that drive market economies. Demand refers to the quantity of a good or service that consumers are willing and able to buy at different prices. Supply is the quantity that producers are willing and able to sell.

供给与需求是驱动市场经济的力量。需求是指在不同价格水平下，消费者愿意且有能力购买的商品或服务数量。供给是生产者愿意且有能力出售的数量。

The law of demand states that, other things being equal, as the price of a good rises, the quantity demanded falls. The law of supply says that as price rises, the quantity supplied usually increases, because higher prices offer greater potential profit.

需求定律说明，在其他条件相同的情况下，当商品价格上升时，需求量下降。供给定律指出，当价格上升时，供给量通常增加，因为更高的价格带来更大的潜在利润。

Demand: Price ↑ → Quantity demanded ↓

需求: 价格 ↑ → 需求量 ↓

Supply: Price ↑ → Quantity supplied ↑

供给: 价格 ↑ → 供给量 ↑

These relationships are the starting point for understanding prices. When you see a sale at a shop, you are watching the law of demand in action: lower prices are used to clear excess stock.

这些关系是理解价格的起点。当你看到商店打折时，你就在见证需求定律的实践：利用更低的价格来清理多余库存。

9. Markets and Prices | 市场与价格

A market is any place or system where buyers and sellers exchange goods, services, or resources. It does not have to be a physical place; online platforms like auction sites are also markets. Prices in a market emerge from the interaction of supply and demand.

市场是买方和卖方交换商品、服务或资源的任何场所或系统。它不一定是实体场所；在线平台如拍卖网站也是市场。市场价格由供给与需求的相互作用产生。

The equilibrium price is the point where quantity demanded equals quantity supplied. At this price, there is no shortage or surplus. If a price is set too high, a surplus develops; if too low, a shortage appears, often leading to queues or empty shelves.

均衡价格是指需求量等于供给量的点。在这个价格上，没有短缺也没有过剩。如果价格定得太高，会产生过剩；如果太低，则会出现短缺，往往导致排队或货架空置。

Prices act as signals in an economy. Rising prices tell producers to make more of a popular product, while falling prices suggest they should cut back. This mechanism, often called the ‘invisible hand’, helps allocate resources without anyone giving orders.

价格在经济体中起着信号作用。价格上涨告诉生产者要多生产热门产品，价格下跌则提示他们应减产。这种机制常被称为’看不见的手’，它无需任何人发号施令就能帮助配置资源。

10. Introduction to Economic Sectors | 经济部门简介

An economy can be divided into three main sectors based on the types of activities undertaken. The primary sector involves extracting and harvesting natural resources, such as farming, fishing, mining, and forestry.

经济可以根据所从事的活动类型分为三个主要部门。第一产业涉及自然资源的开采和收获，如农业、渔业、采矿和林业。

The secondary sector turns raw materials into finished goods. Manufacturing, construction, and car assembly are all examples. This sector adds value to the raw inputs and creates tangible products we can use.

第二产业将原材料转化为成品。制造业、建筑业和汽车装配都是例子。这一部门为原始投入增加价值，创造可供我们使用的有形产品。

The tertiary sector provides services rather than physical goods. It covers a huge range, including retail, education, healthcare, banking, and tourism. In the United Kingdom, over 80% of workers are employed in the tertiary sector.

第三产业提供服务而非实物商品。它覆盖范围极广，包括零售、教育、医疗、银行和旅游。在英国，超过80%的劳动力受雇于第三产业。

As countries develop, the balance between sectors tends to shift from primary towards secondary and then tertiary. Understanding this evolution helps explain why some nations are wealthier and why certain jobs exist where they do.

随着国家发展，部门之间的平衡往往从第一产业转向第二产业，再转向第三产业。理解这一演变有助于解释为什么一些国家更富裕，以及某些工作岗位为何存在于特定地区。

11. Why Study Economics? | 为什么要学习经济学？

Studying economics gives you a toolkit for understanding the world. It explains why people trade, why some nations are rich while others are poor, and how government policies affect your daily life. Economics is not just a subject; it is a way of thinking.

学习经济学为你提供了理解世界的工具箱。它能解释人们为何进行贸易，为何有些国家富裕而另一些贫穷，以及政府政策如何影响你的日常生活。经济学不仅是一门学科，更是一种思维方式。

Economics also sharpens your analytical skills. You will learn to interpret data, weigh costs and benefits, and make informed predictions. These skills are valuable in any career, from business and law to journalism and public policy.

经济学还能提高你的分析能力。你将学会解读数据、权衡成本与收益，并做出明智的预测。这些技能在任何职业中都极具价值，无论是商业、法律、新闻还是公共政策。

Moreover, economic literacy helps you become an active citizen. When you understand concepts like inflation, taxation, and public spending, you can better evaluate the promises made by politicians and the news stories you read every day.

此外，经济学素养有助于你成为积极的公民。当你理解了通胀、税收和公共支出等概念后，就能更好地评判政客的承诺和你每天看到的新闻报道。

12. How to Succeed in Year 7 Economics | 如何在七年级经济学中取得成功

Success in Year 7 economics starts with curiosity. Pay attention to prices when you go shopping, discuss with your family why some jobs pay more than others, and follow simple economic news stories on websites for young people. The more you connect what you learn to the real world, the more it will stick.

七年级经济学的成功始于好奇心。购物时留意价格，和家人讨论为什么有些工作薪水更高，关注面向青少年的经济新闻。你越多地将所学与现实世界联系起来，知识就掌握得越牢固。

Keep a vocabulary log of new terms like opportunity cost, scarcity, and equilibrium. Economics has its own language, and mastering it early will give you confidence. Try explaining these ideas to a friend or family member; teaching is one of the best ways to learn.

准备一个词汇日志，记录新术语，如机会成本、稀缺和均衡。经济学有其独特的语言，尽早掌握它会让你充满自信。尝试向朋友或家人解释这些概念；教别人是最好的学习方式之一。

Finally, stay organised. Use a notebook to summarise each topic after a lesson, draw simple diagrams to show the flow of goods and money, and review your notes weekly. A five-minute recap can be more powerful than an hour of last-minute cramming. Welcome to the economist’s mindset – it will serve you for life.

最后，保持有条理。课后用笔记本总结每个主题，绘制简单的示意图展示商品与货币的流动，并每周复习笔记。五分钟的回顾可能比一小时的临时抱佛脚更有效。欢迎进入经济学家的思维模式——它将使你受益终身。
