1. Business Types and Structures | 企业类型与结构
A sole trader is a business owned and operated by one person. The owner has unlimited liability, meaning personal assets can be used to pay business debts.

2. Business Objectives and Stakeholders | 企业目标与利益相关者
The main objective of many businesses is to maximise profit, which is the difference between revenue and costs.

Survival is often the priority for new or struggling businesses, especially during economic downturns.

Conflicting objectives often arise, e.g. higher wages for workers vs. lower labour costs for shareholders.

3. Marketing – The Marketing Mix | 营销 – 营销组合
The marketing mix (often ‘4Ps’) is a set of controllable marketing tools. The four elements are Product, Price, Place, and Promotion.
营销组合（通常称4Ps）是一组可控的营销工具。四个要素分别是产品、价格、渠道和促销。
Product decisions include design, features, quality, branding, and packaging. A product must satisfy customer needs and wants.
产品决策包括设计、特点、质量、品牌和包装。产品必须满足顾客的需求和欲望。
Pricing strategies include cost-plus pricing, competitive pricing, penetration pricing, and skimming. The price must reflect the product’s perceived value and the market.
定价策略包括成本加成定价、竞争性定价、渗透定价和撇脂定价。价格必须反映产品的感知价值和市场状况。
Place (distribution) involves channels through which goods reach the consumer, such as retailers, wholesalers, or direct selling via e-commerce.
渠道（分销）涉及商品到达消费者的途径，例如零售商、批发商或通过电商直接销售。
Promotion covers advertising, sales promotions, public relations, and personal selling. The goal is to communicate the value proposition and persuade customers.
促销涵盖广告、促销活动、公共关系和人员推销。其目的是传达价值主张并说服顾客购买。
In services, the extended mix includes People, Process, and Physical evidence (7Ps). For IGCSE, focus on the core 4Ps.

4. Market Research | 市场调研
Market research gathers information about customers, competitors, and the market to support decision-making.
市场调研收集关于顾客、竞争者和市场的信息，以支持决策。
Primary research (field research) involves collecting new data directly, e.g. surveys, interviews, focus groups, observations. It is specific but time-consuming and expensive.
一手调研（实地调研）是直接收集新数据，例如问卷调查、访谈、焦点小组和观察。其针对性强，但耗时且成本高。
Secondary research (desk research) uses existing data, e.g. government reports, internet, trade journals. It is cheaper and faster but may be outdated or less relevant.
二手调研（案头调研）使用现有数据，如政府报告、互联网和行业杂志。成本低、速度快，但可能过时或相关性不足。
Quantitative data is numerical and can be analysed statistically (e.g. sales figures, ratings). Qualitative data is descriptive and explores opinions and reasons (e.g. customer comments).
定量数据是数值型数据，可进行统计分析（如销售额、评分）。定性数据是描述性数据，探讨意见和原因（如顾客评价）。
A good research mix combines both types to reduce risk and bias.
合理的调研方法将两者结合，以降低风险和偏差。
5. Operations Management | 运营管理
Operations management deals with the production of goods and services efficiently.
运营管理涉及商品和服务的高效生产。
Job production creates one-off, customised products. It is labour-intensive and flexible but has high unit costs. Suitable for bespoke furniture or wedding cakes.
单件生产制造一次性、定制化的产品。它劳动密集、灵活，但单位成本高。适用于定制家具或婚礼蛋糕。
Batch production makes a group of identical items before switching to another group. It balances flexibility and efficiency, used for baked goods or clothing.
批量生产先生产一组相同产品，再切换到另一组。它平衡了灵活性与效率，用于烘焙食品或服装。
Flow (mass) production continuously produces large volumes of standardised products with high automation. Low unit costs but inflexible. Used for cars, electronics.
流水线（大规模）生产持续生产大批量标准化产品，自动化程度高。单位成本低但灵活性差，用于汽车、电子产品。
Lean production aims to reduce waste and improve quality. Just-in-time (JIT) inventory management orders materials only when needed, reducing storage costs but requiring reliable suppliers.
精益生产旨在减少浪费和提高质量。准时制（JIT）库存管理仅在需要时才订购物料，降低了仓储成本，但要求供应商可靠。
6. Finance – Profit and Cash Flow | 财务 – 利润与现金流
Revenue is the income from selling products. Revenue = Price × Quantity sold.
收入是销售产品的所得。收入 = 价格 × 销量。
Total costs are the sum of fixed costs (e.g. rent) and variable costs (e.g. raw materials). Total Costs = Fixed Costs + (Variable Cost per unit × Quantity).
总成本是固定成本（如租金）与变动成本（如原材料）之和。总成本 = 固定成本 + (单位变动成本 × 数量)。
Profit is calculated as Profit = Revenue – Total Costs. Profit is an accounting concept, whereas cash flow refers to money moving in and out of the business.
利润计算公式为利润 = 收入 – 总成本。利润是会计概念，而现金流指的是企业现金的流入和流出。
A business can be profitable but run out of cash if customers delay payments (credit). Cash flow forecasts help predict cash shortages.
企业可能盈利，但如果客户延迟付款（赊销），可能会导致现金枯竭。现金流量预测有助于预见现金短缺。
Break-even point is where total revenue equals total costs (neither profit nor loss). Break-even output = Fixed Costs ÷ (Selling Price – Variable Cost per unit). The margin of safety shows how much sales can fall before a loss occurs.
盈亏平衡点是指总收入等于总成本时的产量（既无利润也无亏损）。盈亏平衡产量 = 固定成本 ÷ (售价 – 单位变动成本)。安全边际表示在发生亏损之前销售量可下降的幅度。
7. Financial Ratio Analysis | 财务比率分析
Profitability ratios measure how well a business converts sales into profit.
盈利能力比率衡量企业将销售转化为利润的能力。
Gross Profit Margin (%) = (Gross Profit ÷ Revenue) × 100
毛利率 (%) = (毛利 ÷ 营收) × 100
A higher margin indicates efficient control of cost of sales.
毛利率越高，说明成本控制越好。
Net Profit Margin (%) = (Net Profit ÷ Revenue) × 100
净利率 (%) = (净利润 ÷
