1. What is Business? | 什么是商业？
A business is an organisation that provides goods or services to satisfy customers’ needs and wants, usually with the aim of making a profit. Goods are physical, tangible products such as food, books and smartphones, while services are intangible activities like haircuts, education and transport.
企业是提供商品或服务以满足顾客需求和欲望、通常以盈利为目的的组织。商品是有形的实物产品，如食物、书籍和智能手机，而服务是无形的活动，如理发、教育和交通。
Businesses can be local, national or international. A local business serves a nearby community, a national business operates across one country, and an international business trades in multiple countries.
企业可以是本地、国内或国际的。本地企业服务附近的社区，国内企业在一个国家内运营，国际企业在多个国家开展贸易。
The basic profit equation is central to business activity. Profit is the surplus remaining after all costs are deducted from revenue.
基本的利润方程是商业活动的核心。利润是收入扣除所有成本后的剩余部分。
Profit = Revenue − Costs
利润 = 收入 – 成本
2. Scarcity and Choice | 稀缺性与选择
Resources such as land, labour, capital and time are limited, while human wants for goods and services are unlimited. This fundamental problem is called scarcity.
土地、劳动力、资本和时间等资源是有限的，而人类对商品和服务的欲望是无限的。这一基本问题称为稀缺性。
Scarcity forces individuals, businesses and governments to make choices about how to allocate resources. Every choice involves sacrificing the next best alternative, which is the opportunity cost.
稀缺性迫使个人、企业和政府就如何分配资源做出选择。每个选择都涉及放弃次优选项，即机会成本。
For example, if a business uses its available cash to buy a new delivery van, the opportunity cost might be the expansion of its social media advertising campaign. Businesses must weigh opportunity costs to use resources efficiently.
例如，如果一家企业用可用现金购买新的送货货车，机会成本可能是扩大其社交媒体广告活动。企业必须权衡机会成本以有效利用资源。
3. Factors of Production | 生产要素
The resources used to produce goods and services are grouped into four factors of production: land, labour, capital and enterprise.
用于生产商品和服务的资源被归纳为四种生产要素：土地、劳动力、资本和企业精神。
Land includes all natural resources such as forests, minerals, oil and water. Labour refers to the human effort, both physical and mental, involved in production. Capital is the man-made equipment, machinery and buildings used to produce other goods. Enterprise is the skill of combining the other factors to create products, usually driven by entrepreneurs who take risks.
土地包括所有自然资源，如森林、矿产、石油和水。劳动力指生产中投入的体力和脑力劳动。资本是用于生产其他产品的人造设备、机器和建筑。企业精神是组合其他要素创造产品的技能，通常由承担风险的企业家驱动。
Each factor earns a reward: land earns rent, labour earns wages, capital earns interest and enterprise earns profit. Understanding these factors helps explain how value is created in an economy.
每种要素获得相应的报酬：土地获得地租，劳动力获得工资，资本获得利息，企业精神获得利润。理解这些要素有助于解释经济中价值是如何创造的。
4. Types of Business Organisation | 企业组织形式
Businesses can be set up in different legal structures, each with its own advantages and disadvantages. Common types include sole traders, partnerships, private limited companies, public limited companies and franchises.
企业可以设立为不同的法律结构，每种各有利弊。常见类型包括个体经营者、合伙企业、私人有限公司、公众有限公司和特许经营。
A sole trader is a business owned and run by one person. It is easy to set up and the owner keeps all profits, but they have unlimited liability – meaning personal assets can be used to pay business debts.
个体经营者是由一个人拥有和经营的企业。设立简单，所有者获得全部利润，但承担无限责任——意味着个人资产可能被用于偿还企业债务。
A partnership involves 2 to 20 owners who share decision-making and profits. Partners usually have unlimited liability unless they form a limited liability partnership. Private limited companies (Ltd) are owned by shareholders who have limited liability, but shares cannot be sold to the public.
合伙企业涉及2至20个所有者共享决策和利润。除非成立有限责任合伙，合伙人通常承担无限责任。私人有限公司(Ltd)由股东拥有，承担有限责任，但股票不能向公众出售。
Public limited companies (PLC) can sell shares on the stock exchange, allowing them to raise large amounts of capital, but they must publish detailed financial accounts and face stricter regulations. A franchise allows a person to trade under the name and system of an established brand, paying fees and royalties to the franchisor.
公众有限公司(PLC)可在证券交易所出售股份，能筹集大量资本，但必须公布详细财务报表并接受更严格的监管。特许经营允许个人使用知名品牌的名称和系统进行经营，并向特许人支付费用和特许权使用费。
- Unlimited liability: owner is personally responsible for all debts.
- Limited liability: shareholders only lose the amount invested, keeping personal assets safe.
- 无限责任：所有者对所有债务承担个人责任。
- 有限责任：股东只亏损投资额，个人资产受到保护。
5. Entrepreneurs and Business Objectives | 企业家与商业目标
Entrepreneurs are individuals who spot business opportunities, take risks and organise the factors of production to launch and grow a business. They need skills such as creativity, resilience and the ability to make quick decisions.
企业家是发现商业机会、承担风险并组织生产要素以创办和发展企业的个人。他们需要创造力、韧性和快速决策等技能。
Businesses set objectives to guide their direction. Common objectives include making a profit, surviving in the early stages, growing market share, providing a quality service and, for social enterprises, making a positive social or environmental impact. Objectives can change over time; a start-up may focus on survival first and then shift to profit maximisation.
企业设定目标以指引方向。常见目标包括盈利、在早期生存、扩大市场份额、提供优质服务，以及对社会企业而言，产生积极的社会或环境影响。目标可能随时间改变；初创企业可能先求生存，再转向利润最大化。
Social enterprises like charities or community interest companies aim to reinvest profits into their social mission. Their success is measured not only by profit but also by social benefit, such as reducing poverty or improving environmental outcomes.
像慈善机构或社区利益公司这样的社会企业旨在将利润再投资于其社会使命。它们的成功不仅以利润衡量，还以社会效益衡量，例如减少贫困或改善环境成果。
6. Stakeholders | 利益相关者
A stakeholder is any individual or group that has an interest in or is affected by a business’s decisions and actions. Stakeholders can be internal (owners, managers, employees) or external (customers, suppliers, government, local community, banks, pressure groups).
利益相关者是对企业决策和行动有利益关系或受其影响的任何个人或群体。利益相关者可以是内部的（所有者、管理者、员工）或外部的（顾客、供应商、政府、当地社区、银行、压力团体）。
Different stakeholders often have conflicting objectives. For example, shareholders may want higher dividends and profits, whereas employees seek better wages and job security. The local community might want the business to reduce noise and pollution, while suppliers want the business to place larger orders.
不同的利益相关者往往有相互冲突的目标。例如，股东可能希望更高的股息和利润，而员工追求更好的工资和工作保障。当地社区可能希望企业减少噪音和污染，而供应商希望企业下更大的订单。
Managers must balance these interests to maintain a sustainable business. Good stakeholder engagement can lead to better reputation and long-term success.
管理者必须平衡这些利益以维持可持续经营。良好的利益相关者参与可以带来更好的声誉和长期成功。
7. Introduction to Marketing | 市场营销导论
Marketing is the process of identifying, anticipating and satisfying customer needs profitably. A successful business understands its target market and uses the marketing mix to reach customers effectively.
市场营销是识别、预测并盈利地满足顾客需求的过程。成功的企业了解其目标市场，并利用营销组合有效触达顾客。
The marketing mix is often summarised as the 4Ps: Product, Price, Place and Promotion. Product includes design, features, quality, branding and packaging. Price strategies include cost-plus pricing, competitive pricing and penetration pricing. Place covers distribution channels, such as retail stores, online shops and wholesalers. Promotion involves advertising, public relations, sales promotions and social media marketing.
营销组合通常归纳为4P：产品、价格、地点、促销。产品包括设计、特性、质量、品牌和包装。价格策略包括成本加成定价、竞争性定价和渗透定价。地点涵盖分销渠道，如零售店、网店和批发商。促销涉及广告、公关、促销活动和社交媒体营销。
Market research helps businesses gather data about customer preferences, competitors and trends. Primary research (e.g. surveys, interviews) collects new data, while secondary research uses existing information (e.g. reports, internet data).
市场调研帮助企业收集关于顾客偏好、竞争对手和趋势的数据。一手调研（如调查、访谈）收集新数据，二手调研利用现有信息（如报告、互联网数据）。
8. Production and Operations | 生产与运营
Production is the process of converting inputs (factors of production) into outputs (finished goods and services) that satisfy consumers. Business operations must be managed efficiently to control costs and maintain quality.
生产是将投入（生产要素）转化为满足消费者的产出（成品和服务）的过程。必须高效管理企业运营以控制成本和保持质量。
There are three main methods of production: job production (making one-off, custom items like a wedding cake or a bridge), batch production (producing a set number of identical items, e.g. batches of bread), and flow production (continuous, large-scale production, as used in car assembly lines). Each method suits different business needs and demand volumes.
有三种主要的生产方式：作业生产（制作一次性定制产品，如婚礼蛋糕或桥梁），批量生产（生产一定数量的相同产品，如一批面包），和流水生产（连续大规模生产，如汽车装配线）。每种方法适合不同的企业需求和需求量。
Efficiency is gaining more output from the same or fewer inputs. Lean production techniques, such as reducing waste and improving workflows, help raise efficiency. Technology, including automation, robotics and computer-aided design (CAD), plays a major role in modern production.
效率是用相同或更少的投入获得更多产出。精益生产技术，如减少浪费和改善工作流程，有助于提高效率。技术，包括自动化、机器人和计算机辅助设计(CAD)，在现代生产中扮演重要角色。
9. Business Finance and Sources of Finance | 商业财务与资金来源
All businesses need finance to start up (start-up capital), cover day-to-day running costs (working capital) and fund expansion. Understanding financial terms is essential for planning and decision-making.
所有企业都需要资金来启动（启动资金）、支付日常运营成本（营运资金）和为扩张提供资金。理解财务术语对规划和决策至关重要。
Internal sources of finance come from within the business, such as retained profit (profit reinvested rather than paid to owners) and selling unused assets. External sources include bank loans, overdrafts, trade credit, crowdfunding and venture capital. Each source has a different cost, risk and repayment condition.
内部资金来源来自企业内部，如留存利润（再投资而不分给所有者的利润）和出售未使用的资产。外部来源包括银行贷款、透支、贸易信贷、众筹和风险资本。每种来源有不同的成本、风险和偿还条件。
Key financial concepts include revenue (the money from sales), costs (fixed costs like rent and variable costs like raw materials) and cash flow (the movement of money in and out of the business). A business can be profitable but still fail if it runs out of cash.
关键财务概念包括收入（销售收入）、成本（固定成本如租金和可变成本如原材料）以及现金流（资金进出企业的流动）。企业可能盈利但如果耗尽现金仍然会失败。
Break-even analysis shows the minimum sales needed to cover total costs. The break-even point can be calculated using the formula:
盈亏平衡分析显示覆盖总成本所需的最低销售额。盈亏平衡点可用以下公式计算：
Break-even Point = Fixed Costs ÷ (Selling Price per Unit − Variable Cost per Unit)
盈亏平衡点 = 固定成本 ÷（单价 – 单位可变成本）
10. Business Environment and Ethics | 商业环境与道德
Businesses do not operate in isolation; they are affected by the external environment. Key factors include economic conditions (e.g. interest rates, consumer spending), legal regulations, technological changes, social attitudes and environmental issues.
企业并非孤立运营，它们受外部环境影响。关键因素包括经济状况（如利率、消费者支出）、法律法规、技术变革、社会态度和环境问题。
All businesses must comply with the law, such as employment law (protecting workers’ rights), consumer protection law (ensuring products are safe) and tax regulations. Failure to comply can lead to fines, legal action or damage to reputation.
所有企业必须遵守法律，如就业法（保护工人权利）、消费者保护法（确保产品安全）和税收法规。不合规可能导致罚款、法律诉讼或声誉受损。
Ethics refers to making decisions based on moral principles, even when not required by law. An ethical business might use Fairtrade supplies, pay workers a living wage or reduce packaging waste. Sustainability means meeting present needs without compromising the ability of future generations to meet their own needs. Businesses can adopt renewable energy, recycle materials and design eco‑friendly products.
道德指基于道德原则做决策，即便法律未要求。道德企业可能使用公平贸易物资、支付工人生活工资或减少包装废弃物。可持续性意味着满足当前需求而不损害后代满足其自身需求的能力。企业可以采用可再生能源、回收材料和设计环保产品。
Acting responsibly often creates a positive brand image and can lead to higher long-term profits, but short-term costs may increase. Stakeholders increasingly expect businesses to balance profit with purpose.
负责任行事通常塑造积极的品牌形象，并可能导致更高的长期利润，但短期成本可能上升。利益相关者日益期望企业在利润与使命之间取得平衡。
