1. The Purpose and Nature of Business | 商业的目的与性质
Needs, Wants and Scarcity: A need is something essential for survival, such as food, water and shelter. A want is a desire that is not necessary for survival, like a smartphone. Because resources are limited but wants are unlimited, scarcity exists. Businesses combine factors of production (land, labour, capital, enterprise) to produce goods and services that satisfy needs and wants.
需求、欲望与稀缺性：需求是生存所必需的，例如食物、水和住所。欲望是并非生存所必需的愿望，例如智能手机。由于资源有限而欲望无限，稀缺性便产生了。企业将生产要素（土地、劳动力、资本、企业家精神）组合起来，生产能够满足需求和欲望的商品与服务。
Goods and Services: Goods are tangible items, either consumer goods (e.g. clothing) or capital goods (e.g. machinery). Services are intangible activities performed for customers (e.g. haircuts, banking).
商品与服务：商品是有形物品，分为消费品（如服装）和资本品（如机器）。服务是为顾客提供的无形活动（如理发、银行服务）。
Added Value: Added value is the difference between the selling price and the cost of materials. A business can increase added value by reducing input costs, increasing the selling price, or improving the product’s design and quality.
附加值：附加值是指售价与原料成本之间的差额。企业可以通过降低投入成本、提高售价或改进产品设计和质量来增加附加值。
2. Forms of Business Organisation | 企业组织形式
Sole Trader: A business owned and run by one person. The owner has unlimited liability, meaning personal assets are at risk if the business fails. Advantages include easy set‑up and full control. A disadvantage is the difficulty in raising capital.
个体工商户：由一人拥有并经营的企业。业主承担无限责任，即如果企业倒闭，个人资产会面临风险。优点是设立简便、完全控制; 缺点则是筹集资金困难。
Partnership: Owned by 2 to 20 partners who share profits and responsibilities. A deed of partnership is often used. Partners usually have unlimited liability, though some can be ‘sleeping’ partners. The main advantage is more capital and shared expertise; the main disadvantage is the risk of disputes and unlimited liability.
合伙制企业：由2至20名合伙人共同拥有，分享利润并分担责任。通常会签订合伙协议。合伙人一般承担无限责任，但也可有“隐名合伙人”。主要优势是可获得更多资金和共同专长；主要劣势是存在纠纷风险以及无限责任。
Private Limited Company (Ltd): Shares cannot be sold to the public. Shareholders have limited liability, protecting personal wealth. The company has a separate legal identity. It must publish financial accounts and is run by directors.
私人有限公司 (Ltd)：股份不得向公众出售。股东承担有限责任，个人财产受到保护。公司具有独立法人资格，必须发布财务账目，并由董事经营。
Public Limited Company (Plc): Can sell shares on the stock exchange to raise large amounts of capital. There is a risk of takeover. It is subject to more regulation and must disclose detailed accounts.
公众有限公司 (Plc)：可在证券交易所发行股票以筹集大量资本。存在被收购的风险。受到的监管更多，必须披露详细的账目。
3. Business Objectives and Stakeholder Objectives | 商业目标与利益相关者目标
Common Business Objectives: Profit maximisation, growth, increasing market share, survival, providing a social service (in social enterprises). Objectives may change over time depending on the business environment and stage of development.
常见商业目标：利润最大化、增长、提高市场占有率、生存、提供社会服务（社会企业）。目标可能随商业环境和发展阶段而改变。
Stakeholders: Stakeholders are individuals or groups who have an interest in a business. Internal stakeholders include owners and employees. External stakeholders include customers, suppliers, the government, the local community and pressure groups. Their objectives can conflict: workers want higher wages, while shareholders want higher dividends; customers want low prices, whereas owners want high profits.
利益相关者：利益相关者是对企业享有利益的个人或群体。内部利益相关者包括所有者与员工。外部利益相关者包括顾客、供应商、政府、当地社区和压力团体。他们的目标可能互相冲突：工人希望提高工资，而股东希望更高股息；顾客想要低价，而所有者追求高利润。
4. Marketing: Research and the Marketing Mix | 市场营销：调研与营销组合
Market Research: Primary research collects first‑hand data (e.g. questionnaires, interviews, observations). It is up‑to‑date but can be expensive. Secondary research uses existing data (e.g. internet, government reports). It is cheaper and quicker but may be out‑of‑date. Both help a business identify customer needs and make informed decisions.
市场调研：一手调研收集第一手数据（如问卷、访谈、观察），信息及时但成本高。二手调研利用已有数据（如互联网、政府报告），更便宜更快但可能过时。两者都有助于企业识别顾客需求并做出明智决策。
Market Segmentation: Markets can be divided by demographic, geographic, psychographic and behavioural factors. Segmentation allows businesses to target specific groups more effectively.
市场细分：市场可按人口统计、地理、心理和行为因素进行细分。细分可使企业更有效地瞄准特定群体。
The Marketing Mix (4Ps):
- Product – design, features, brand, packaging. / 产品 – 设计、特性、品牌、包装。
- Price – cost‑plus, penetration, skimming, competitive pricing. / 价格 – 成本加成、渗透定价、撇脂定价、竞争定价。
- Place – distribution channels, retailers, online sales. / 渠道 – 分销渠道、零售商、在线销售。
- Promotion – advertising, sales promotions, public relations, social media. / 促销 – 广告、促销活动、公共关系、社交媒体。
5. Operations and Production | 运营与生产
Methods of Production: Job production makes one‑off items (high quality, flexible, high cost). Batch production makes groups of identical products (moderate cost and flexibility). Flow production involves continuous mass production (low unit cost, efficient, but inflexible). The choice depends on demand, the product and available technology.
生产方法：单件生产制造一次性产品（质量高、灵活、成本高）。批量生产生产一组相同产品（成本与灵活性适中）。流水生产进行连续大规模生产（单位成本低、高效但不灵活）。选择哪种方法取决于需求、产品和可用技术。
Economies and Diseconomies of Scale: As a business grows, average costs may fall due to purchasing, marketing, technical and financial economies. However, beyond a point, diseconomies can occur—poor communication, low morale, coordination problems—causing average costs to rise.
规模经济与规模不经济：随着企业扩大，由于采购、营销、技术和财务方面的经济性，平均成本可能下降。但超过某一点后可能出现规模不经济——沟通不畅、士气低落、协调问题——导致平均成本上升。
6. Financial Information: Cash Flow and Profit | 财务信息：现金流与利润
Cash Flow: Cash inflow is money received (sales, investments). Cash outflow is money paid (raw materials, wages, rent). A cash flow forecast predicts future flows and helps identify liquidity problems. A negative closing balance risks insolvency. Solutions include delaying outflows, chasing debtors and arranging an overdraft.
现金流：现金流入是收到的款项（销售、投资）。现金流出是支付的款项（原材料、工资、租金）。现金流预测可预估未来流动并帮助发现流动性问题。期末现金余额为负有资不抵债的风险。解决办法包括延迟付款、催收欠款和安排透支。
Profit and Loss: Profit is the reward for risk‑taking. Gross profit = revenue minus cost of sales. Net profit = gross profit minus expenses. Profit can be reinvested or distributed. A business can survive without profit for a while, but cannot survive without cash.
利润与亏损：利润是对承担风险的回报。毛利润 = 销售收入 – 销售成本。净利润 = 毛利润 – 费用。利润可用于再投资或分配。企业暂时没有利润尚可生存，但没有现金则无法生存。
7. Break‑Even and Cost–Volume–Profit Analysis | 盈亏平衡与成本-量-利分析
Break‑Even Point: The level of output where total revenue equals total costs, so the business makes neither profit nor loss. The formula is:
Break‑Even Output = Fixed Costs ÷ (Selling Price per Unit – Variable Cost per Unit)
盈亏平衡点：总收益等于总成本的产量水平，企业既无利润也无亏损。公式为：盈亏平衡产量 = 固定成本 ÷ (单位售价 – 单位可变成本)。
Margin of Safety: Actual output minus break‑even output. It shows how far sales can fall before a loss occurs. A high margin of safety reduces risk.
安全边际：实际产量 – 盈亏平衡产量。显示销售额下降多少才会出现亏损。安全边际越高，风险越低。
Limitations: Break‑even assumes all output is sold and costs are linear, which may not always be true. It is best used as a planning tool alongside other methods.
局限性：盈亏平衡假设全部产出均被售出且成本线性，这并不总是成立。最好将其作为一种规划工具，结合其他方法使用。
8. Sources of Finance | 资金来源
Internal Sources: Retained profit (reinvested net profit), sale of assets, reducing stock levels. These do not increase debt and are quick to arrange but may be limited.
内部来源：留存利润（再投资的净利润）、出售资产、降低库存水平。这不会增加债务，安排快速，但可能金额有限。
External Sources: Short‑term – overdraft (flexible, interest charged on amount used), trade credit. Long‑term – bank loans (repayment with interest), share issue (only for limited companies), venture capital, grants and crowdfunding. The choice depends on cost, control and risk.
外部来源：短期 – 透支（灵活，按使用金额计息）、贸易信贷。长期 – 银行贷款（需偿还本息）、发行股份（仅限有限公司）、风险投资、补助金与众筹。选择依据成本、控制权与风险。
9. Human Resources | 人力资源
Recruitment and Selection: The process begins with a job analysis, followed by a job description and person specification. Internal recruitment is cheaper and motivates staff; external recruitment brings new ideas. Selection methods include interviews, tests and assessment centres.
招聘与选拔：流程始于工作分析，随后是工作描述与人岗匹配说明。内部招聘成本低且能激励员工；外部招聘带来新思路。选拔方法包括面试、测试和评估中心。
Training: Induction training welcomes new employees. On‑the‑job training is practical but can disrupt production. Off‑the‑job training uses external courses and may be more effective for new concepts. Training can increase productivity, quality and motivation.
培训：入职培训帮助新员工适应；在职培训实用但可能干扰生产；脱产培训利用外部课程，对新概念可能更为有效。培训能提升生产率、质量与积极性。
Motivation: Financial methods include wages, salaries, commission and bonuses. Non‑financial methods include job enrichment, team‑working and praise. Herzberg’s hygiene factors (pay, conditions) prevent dissatisfaction, while motivators (achievement, recognition) create satisfaction.
激励：经济性方法包括工资、薪金、佣金和奖金。非经济性方法包括工作丰富化、团队协作和表扬。赫茨伯格的双因素理论中，保健因素（工资、工作条件）防止不满，激励因素（成就、认可）带来满意。
10. External Environment and Globalisation | 外部环境与全球化
External Influences: Businesses must respond to economic changes (inflation, unemployment, interest rates), legal controls (employment law, consumer protection), environmental pressures (recycling, sustainable production) and technological advances. Failure to adapt can damage reputation and profitability.
外部影响：企业必须应对经济变化（通胀、失业、利率）、法律管制（劳动法、消费者保护）、环境压力（回收、可持续生产）和技术进步。若不能适应，可能损害声誉和盈利能力。
Globalisation: Globalisation increases opportunities for expansion, access to cheaper suppliers and larger markets. It also brings challenges such as cultural differences, exchange rate fluctuations and competition from multinational corporations. Multinationals can create jobs but may also exploit workers and damage local environments.
全球化：全球化增加了扩张、获取廉价供应商和更大市场的机会。同时也带来文化差异、汇率波动和来自跨国公司的竞争等挑战。跨国公司能创造就业，但也可能压榨工人并破坏当地环境。
Exchange Rates: A depreciation makes exports cheaper and imports dearer; an appreciation does the opposite. This affects competitiveness and costs for businesses trading internationally.
汇率：货币贬值使出口更便宜、进口更昂贵；升值则相反。这会影响从事国际贸易的企业的竞争力和成本。
