1. Scarcity and the Basic Economic Problem | 稀缺性与基本经济问题
Scarcity is the fundamental economic problem. It means we have unlimited wants but only limited resources such as time, money, workers and raw materials. Because of scarcity, we cannot have everything we desire, so we must make choices.
稀缺性是基本的经济问题。它意味着我们有无限的欲望，但只拥有有限的时间、金钱、劳动力和原材料等资源。由于稀缺性的存在，我们无法拥有想要的一切，因此必须做出选择。
Every society faces three basic economic questions: What to produce? How to produce? For whom to produce? These questions arise directly from scarcity and force us to allocate resources carefully.
每个社会都会面临三个基本经济问题：生产什么？如何生产？为谁生产？这些问题直接源于稀缺，迫使我们谨慎分配资源。
Memory tip: Think "Scarce means Select" – both start with S. When you see scarcity, remember a choice must be made.
记忆技巧： 联想 "Scarce 即 Select"——两个词都以 S 开头。看到稀缺性，就记得必须做出选择。
2. Needs and Wants | 需要与想要
Needs are things we must have to survive, such as food, clean water, shelter and basic clothing. Wants are things we would like to have but can live without, such as video games, designer shoes or holidays abroad.
需要是我们为生存而必须拥有的东西，例如食物、洁净的水、住所和基本衣物。想要则是我们希望拥有但没有也能生活的东西，例如电子游戏、名牌鞋或海外度假。
Understanding the difference helps individuals and governments prioritise spending. A person should satisfy needs before spending on wants. Similarly, a government may use tax money on healthcare (a need) before building a new sports stadium (a want).
理解两者的区别有助于个人和政府确定支出的优先次序。一个人应当先满足需要，再为想要花钱。同样，政府也可能先把税收用于医疗（需要），再建造新的体育场（想要）。
| English Term | 中文术语 | Example / 例子 |
|---|---|---|
| Need | 需要 | Drinking water / 饮用水 |
| Want | 想要 | Cinema ticket / 电影票 |
3. Goods and Services | 商品与服务
Goods are physical items that you can touch and own. They are tangible. Examples include a bicycle, a loaf of bread or a smartphone. Services are actions performed for you by someone else. They are intangible – you cannot hold a haircut or a bus journey.
商品是你可以触摸和拥有的实物，是有形的。例子包括自行车、一条面包或一部智能手机。服务是他人为你执行的行为，是无形的——你无法抓住一个理发服务或一段公交旅程。
Economists often group goods into consumer goods (for direct use) and capital goods (used to produce other goods). Services range from banking to cleaning. Most everyday purchases involve a mixture: buying a pizza is buying a good, while having it delivered involves a service.
经济学家常把商品分为消费品（直接使用）和资本品（用于生产其他商品）。服务则从银行服务到清洁服务，种类繁多。大部分日常消费都混合了二者：买比萨是购买商品，而送货上门则涉及服务。
Memory tip: "Goods you can grab, Services you experience." The G's link together: Goods – Grab.
记忆技巧： "Goods 你可以抓住 (grab)，Services 你体验 (experience)。" 英文中 Goods 和 Grab 都以 G 开头。
4. Opportunity Cost and Trade-offs | 机会成本与权衡
Opportunity cost is the value of the next best alternative you give up when you make a choice. It is not all the alternatives, only the one you valued most after your chosen option. For example, if you spend your last £10 on a cinema ticket instead of a new book, the opportunity cost is the enjoyment you would have had from the book.
机会成本是你做出选择时放弃的次优替代方案的价值。它不是所有其他选项，仅仅是你选中项之后你最看重的那个。例如，如果你把仅剩的10英镑花在电影票上而不是一本新书，那么机会成本就是你原本从书中获得的乐趣。
A trade-off means giving up some of one thing to get more of another. In a decision, all the alternatives you sacrifice represent the trade-off. Opportunity cost is the single most valuable item within that trade-off.
权衡意味着为了获得更多某物而放弃一些别的东西。在决策中，你牺牲的所有替代方案就是权衡。机会成本则是该权衡中最有价值的那一项。
Memory trick: "Opportunity Cost = Opportunity Lost." u turn left, so you miss the view on the right. That missed view is your opportunity cost.
记忆诀窍： "机会成本 = 失去的机会。" 想象一个路标：你向左转了，所以错过了右边的风景。那错过的风景就是你的机会成本。
5. Producers and Consumers | 生产者与消费者
Producers are individuals or businesses that make goods or provide services. They combine resources such as labour, land and capital to create products. Consumers are people who buy and use these goods and services to satisfy their needs and wants.
生产者是制造商品或提供服务的个人或企业。他们组合劳动力、土地和资本等资源来创造产品。消费者则是购买和使用这些商品与服务以满足自身需要和想要的人。
In a market economy, producers and consumers interact continuously. Producers respond to consumer demand, and consumers benefit from competition among producers. Circular flow models show money flowing from consumers to producers in exchange for products, while resources flow from households to firms.
在市场经济中，生产者与消费者持续互动。生产者对消费者需求做出反应，消费者则从生产者之间的竞争中受益。循环流动模型显示货币从消费者流向生产者以交换产品，而资源从家庭流向企业。
Quick check: Think of a baker (producer) and someone who buys bread (consumer). The baker uses flour (resource) to make bread (good).
快速自查： 想想面包师（生产者）和买面包的人（消费者）。面包师使用面粉（资源）制作面包（商品）。
6. Supply and Demand | 供给与需求
Demand is the willingness and ability of consumers to purchase a good or service at different prices. Generally, as price falls, quantity demanded rises – this is the law of demand. Supply is the willingness and ability of producers to offer a product for sale. According to the law of supply, as price rises, quantity supplied usually increases.
需求是消费者在不同价格下购买商品或服务的意愿和能力。通常，价格下降时，需求量上升——这就是需求定律。供给是生产者提供产品出售的意愿和能力。根据供给定律，价格上升时，供给量通常也会增加。
Graphically, demand curves slope downward, and supply curves slope upward. Where they intersect is called the equilibrium price – the point where the amount buyers want equals the amount sellers provide.
在图形上，需求曲线向下倾斜，供给曲线向上倾斜。它们的交点称为均衡价格——买家的需求量与卖家的供给量相等的点。
Memorisation aid: "Demand goes Down as price goes Down – the Double D rule." For supply, "Supply follows the Sun – both rise together."
记忆辅助： "需求随价格下降而下降——双D规则（Demand, Down）。" 对于供给，"供给如朝阳——一起上升 (Supply, Sun, rise)。"
7. Markets and the Price Mechanism | 市场与价格机制
A market is any situation or place where buyers and sellers exchange goods, services or resources. It does not have to be physical – online shops and auction websites are markets too. The price mechanism describes how prices adjust to balance supply and demand.
市场是买卖双方交换商品、服务或资源的任何场合或地点。它不一定是实体的——网店和拍卖网站同样是市场。价格机制描述的是价格如何调整以平衡供给与需求。
When demand exceeds supply, prices tend to rise, signalling producers to supply more. When supply exceeds demand, prices fall, encouraging consumers to buy more. Adam Smith referred to this self‑regulating system as the "invisible hand".
当需求超过供给时，价格趋于上升，这向生产者发出增加供给的信号。当供给超过需求时，价格下降，鼓励消费者购买更多。亚当·斯密将这种自我调节系统称为 "看不见的手"。
Memory hook: "The price mechanism is like a thermostat – it brings a market back to the right temperature (equilibrium)."
记忆钩子： "价格机制就像一个恒温器——它让市场回到合适的温度（均衡）。"
8. Money, Barter and Exchange | 货币、以物易物与交换
Barter is the direct exchange of goods and services without using money. It requires a double coincidence of wants – you must find someone who has what you want and wants what you have. Money overcomes this problem by acting as a medium of exchange accepted by everyone.
以物易物是不使用货币而直接交换商品与服务的方式。它需要欲望的双重巧合——你必须找到一个拥有你想要的物品且同时想要你手里物品的人。货币通过充当人人都接受的交换媒介，解决了这个问题。
Money also serves as a store of value (it keeps its worth over time) and a unit of account (it measures value in a standard way). Modern money includes coins, banknotes and electronic balances.
货币还作为价值储藏手段（其价值能随时间保存）和计价单位（以标准方式衡量价值）。现代货币包括硬币、纸币和电子余额。
Revision rhyme: "Barter needed want for want, money makes buying instant."
复习顺口溜： "以物易物要巧合，货币让购物变利落。"
9. Specialisation and Division of Labour | 专业化与劳动分工
Specialisation means concentrating on a particular task, skill or product to become more efficient. Division of labour is a type of specialisation where a production process is broken into many small steps, each performed by different workers. Adam Smith illustrated this with a pin factory: one worker alone could make perhaps one pin a day, but ten workers specialising in different stages could make thousands.
专业化指专注于某项特定任务、技能或产品以提高效率。劳动分工是专业化的一种形式，将生产过程分解为许多小步骤，每个步骤由不同工人完成。亚当·斯密用大头针工厂做了说明：一名工人单独操作，一天大概只能做一枚针，而十名工人分工合作，却能制造数千枚。
Specialisation increases productivity and often lowers costs. However, it can make work boring and create interdependence – if one stage fails, the whole production can stop.
专业化能提高生产率，常常降低成本。但它也可能让工作变得枯燥，并产生相互依赖性——假如某个环节出问题，整个生产可能停滞。
Memory image: "Specialisation = the 'assembly line' idea. Picture a car being assembled piece by piece – each person is a specialist."
记忆画面： "专业化 = '流水线' 理念。想象一辆汽车被逐块组装——每个人都是一位专才。"
10. Factors of Production and Economic Sectors | 生产要素与经济部门
The four factors of production are the resources used to produce goods and services. Land includes all natural resources (water, minerals, forests). Labour means human effort, both physical and mental. Capital refers to man‑made tools, machines and factories (not money). Enterprise is the ability to bring the other three factors together and take risks in business.
四种生产要素是用于生产商品和服务的资源。土地包括所有自然资源（水、矿产、森林）。劳动力指人的努力，包括体力和脑力。资本指人造工具、机器和厂房（不是金钱）。企业家才能则是把其他三种要素组合起来并承担商业风险的能力。
Economic activity is often split into sectors. The primary sector extracts raw materials (farming, mining). The secondary sector manufactures goods (factories, construction). The tertiary sector provides services (retail, education, healthcare). Thinking about these sectors helps you see how an economy is structured.
经济活动常被划分为不同部门。第一产业采掘原材料（农业、采矿）。第二产业制造商品（工厂、建筑）。第三产业提供服务（零售、教育、医疗）。思考这些部门有助于你理解经济的结构。
| Factor / 要素 | Reward / 报酬 |
|---|---|
| Land / 土地 | Rent / 地租 |
| Labour / 劳动力 | Wages / 工资 |
| Capital / 资本 | Interest / 利息 |
| Enterprise / 企业家才能 | Profit / 利润 |
11. Public and Private Sectors | 公共部门与私营部门
The private sector is made up of businesses owned by individuals or groups of private investors. Their main aim is usually to make a profit. Examples include supermarkets, clothing brands and local hairdressers. The public sector consists of organisations owned and run by the government. They are often funded through taxes and aim to provide services for everyone, such as state schools, the NHS in Scotland, and public roads.
私营部门由个人或私人投资者群体拥有的企业组成。它们的主要目标通常是盈利。例子包括超市、服装品牌和本地理发店。公共部门则由政府拥有和运营的组织构成。它们通常通过税收获得资金，旨在为所有人提供服务，例如公立学校、苏格兰的国家医疗服务体系和公共道路。
Some goods, like street lighting, are called public goods because it is difficult to charge individuals directly for them. These are often provided by the public sector. Merit goods, such as education, are also often subsidised by the state.
有些商品如路灯被称为公共品，因为很难向个人直接收费。这些通常由公共部门提供。教育等有益品也常常得到国家补贴。
Memory cue: "Public = paid by the taxpayer, Private = paid by your own pocket."
记忆提示： "公共 = 纳税人买单，私营 = 自己掏腰包。"
12. Budgets, Income and Expenditure | 预算、收入与支出
A budget is a plan showing expected income and expenditure over a period. Income is money received, such as pocket money, wages or government benefits. Expenditure is money spent on goods and services. A balanced budget means income equals spending. A surplus occurs when income exceeds spending, and a deficit happens when spending is greater than income.
预算是一份列出一段时间内预期收入与支出的计划。收入是收到的钱，如零花钱、工资或政府补助。支出则是花在商品和服务上的钱。平衡预算指收入等于支出。盈余发生在收入大于支出时，赤字则出现在支出大于收入时。
Governments, businesses and households all use budgets to plan ahead. If you save regularly, you are setting aside income today for future expenditure – an important concept called saving.
政府、企业和家庭都使用预算来提前规划。如果你定期存钱，就是把今天的收入留作未来支出——这就是储蓄的重要概念。
Quick formula: Budget = Income − Expenditure. If the result is positive, that's a surplus; negative, a deficit.
简易公式： 预算 = 收入 − 支出。结果为正就是盈余，为负就是赤字。
