1. Business Activity and Enterprise | 商业活动与企业精神
A business is any organisation that uses resources to produce goods and services to satisfy the needs and wants of customers. The basic economic problem is scarcity: unlimited wants but limited resources. This leads to opportunity cost, which is the next best alternative given up when a choice is made. Entrepreneurs combine factors of production – land, labour, capital and enterprise – to create value and earn profit.
企业是任何利用资源生产商品和服务的组织，旨在满足顾客的需要和欲望。基本经济问题是稀缺性：无限的欲望与有限的资源。这导致了机会成本，即当做出选择时所放弃的次优替代方案。企业家组合生产要素——土地、劳动、资本和企业精神——以创造价值并获得利润。
Factors of production:
- Land – natural resources used in production. / 土地——生产所用的自然资源。
- Labour – human effort, both physical and mental. / 劳动——人的体力和脑力付出。
- Capital – man-made goods used to produce other goods, e.g. machinery. / 资本——用于生产其他商品的人造物品，如机器。
- Enterprise – the ability to organise the other three factors and take risks. / 企业精神——组织其他三要素并承担风险的能力。
Characteristics of successful entrepreneurs: risk-taking, creativity, determination, confidence, and the ability to identify market gaps. Adding value is the process of increasing the worth of a product by improving its design, branding or convenience, allowing the business to charge a higher price than the raw material cost.
成功企业家的特质：敢于承担风险、创造力、决心、自信心以及识别市场空白的能力。增值是通过改进设计、品牌或便利性来提升产品价值的过程，使企业能够收取高于原材料成本的价格。
2. Classification of Businesses | 企业分类
Businesses can be classified by the sector of the economy in which they operate. The primary sector extracts raw materials (farming, mining). The secondary sector manufactures goods (car assembly, clothing). The tertiary sector provides services (retail, banking, transport). As an economy develops, the relative importance shifts from primary to secondary to tertiary. Many developed countries now see a growing quaternary sector focusing on knowledge-based services like IT and R&D.
企业可按其经营所处的经济部门进行分类。第一产业开采原材料（农业、采矿）。第二产业制造商品（汽车装配、服装）。第三产业提供服务（零售、银行、运输）。随着经济发展，主导部门从第一产业转向第二产业再到第三产业。许多发达国家现在看到以知识型服务（如IT和研发）为重点的第四产业正在增长。
In terms of private vs public sector: Private sector businesses are owned by individuals or groups of individuals aiming to make a profit. Public sector organisations are owned and controlled by the government, providing essential services (education, healthcare) and may not aim to maximise profit. A mixed economy has both private and public sectors operating side by side.
在私营与公共部门方面：私营企业由个人或个人团体拥有，以盈利为目的。公共部门组织由政府拥有和控制，提供基本服务（教育、医疗），可能不以利润最大化为目标。混合经济中私营和公共部门并存。
3. Business Growth and Size | 企业成长与规模
Businesses can grow internally (organic growth) by expanding their own operations, opening new branches, hiring more staff, or increasing sales. External growth occurs through integration: merging with or taking over another firm. Integration can be horizontal (same industry and stage of production), vertical forward (towards the customer) or vertical backward (towards the supplier), and conglomerate (different industries).
企业可以通过内部成长（有机成长）扩大自身业务、开设新分店、雇佣更多员工或增加销售。外部成长通过整合实现：与另一家公司合并或收购。整合可以是横向（同一行业、同一生产阶段）、垂直前向（向顾客端）、垂直后向（向供应端）和混合（不同行业）。
Advantages of growth include economies of scale: cost per unit falls as output rises. Types of economies: purchasing (bulk buying), technical (better machinery), financial (easier loans), marketing (spreading advertising costs), and managerial (specialist managers). However, a business may grow too large and suffer diseconomies of scale, such as communication problems, poor coordination and low worker motivation.
成长的优势包括规模经济：随着产量上升，单位成本下降。规模经济的类型：采购（批量采购）、技术（更好的机器）、财务（更容易获得贷款）、营销（分摊广告成本）和管理（专业管理人员）。但是，企业规模过大可能会遭受规模不经济，例如沟通问题、协调不良和员工积极性低。
Why some businesses stay small: the market size may be limited; the owner may prefer personal service; the product may be specialised; or the business is a sole trader with limited access to capital. Measuring business size can be done by number of employees, value of sales, capital employed, or market share – but each method has limitations.
为什么一些企业保持小规模：市场规模可能有限；所有者可能偏好个性化服务；产品可能专业化；或企业是个体经营者，获取资本的途径有限。衡量企业规模可以通过员工人数、销售额、资本投入或市场份额——但每种方法都有局限性。
4. Organisation and Management | 组织与管理
An organisational chart shows the structure of a business, including hierarchy, span of control, chain of command, and line of authority. A tall structure has many levels and narrow spans of control; a flat structure has few levels and wide spans. Tall structures give close supervision and clear promotion routes but slow communication. Flat structures allow faster communication and more delegation but may overburden managers.
组织结构图展示了企业的架构，包括层级、控制幅度、指挥链和权力线。高耸结构层级多、控制幅度窄，提供密切监督和清晰的晋升路径，但沟通较慢。扁平结构层级少、控制幅度宽，沟通更快、授权更多，但可能使经理负担过重。
Management roles (Fayol): planning, organising, commanding, coordinating, controlling. Delegation means giving authority to subordinates over specific tasks, but the manager remains accountable. A decentralised structure pushes decision-making down to lower levels, which can improve motivation and responsiveness; a centralised structure keeps decisions at the top, ensuring consistency.
管理角色（法约尔）：计划、组织、指挥、协调、控制。授权意味着将特定任务的职权交给下属，但经理仍需负责。分权结构将决策权下放到底层，有利于提高激励和响应速度；集权结构将决策保留在高层，确保一致性。
Styles of leadership: autocratic (boss decides alone), democratic (employees are consulted), laissez-faire (employees make decisions). The best style depends on the situation, workforce skills and the urgency of the task.
领导风格：专制型（老板独自决定）、民主型（征询员工意见）、放任型（员工自行决策）。最佳风格取决于具体情景、员工技能和任务的紧迫性。
5. Marketing: Market Research and the Marketing Mix | 市场营销：市场调查与营销组合
Marketing is identifying, anticipating and satisfying customer needs profitably. Market research gathers data about consumers and competitors. Primary research (field research) collects new data directly, e.g. questionnaires, interviews, focus groups. Secondary research (desk research) uses existing data, e.g. internet reports, government statistics. Primary research is up-to-date and specific but costly; secondary research is cheaper and faster but may be outdated.
市场营销是识别、预判并有利可图地满足顾客需求。市场调查收集有关消费者和竞争对手的数据。一手调查（实地调查）直接收集新数据，如问卷、访谈、焦点小组。二手调查（案头调查）使用现有数据，如互联网报告、政府统计。一手调查最新且针对性强但成本高；二手调查更便宜快捷但可能过时。
The marketing mix (4Ps): Product, Price, Place, Promotion. Product includes design, quality, branding and USP (unique selling point). Pricing strategies:
| Strategy | Explanation / 解释 |
| Cost-plus | Add a profit mark-up to total cost. / 总成本上加利润加成。 |
| Penetration | Set low price to enter market and gain share. / 渗透定价：以低价进入市场获取份额。 |
| Skimming | High initial price for innovative product. / 撇脂定价：创新产品的高初始价格。 |
| Competitive | Match or undercut rivals' prices. / 竞争性定价：匹配或低于竞争对手价格。 |
| Psychological | Pricing to influence perception, e.g. $9.99. / 心理定价：影响感知，如$9.99。 |
Place refers to distribution channels: direct selling, retailers, wholesalers, e-commerce. Promotion includes advertising, sales promotions, public relations, and personal selling. An integrated marketing mix ensures consistency across all elements.
地点指分销渠道：直销、零售商、批发商、电子商务。促销包括广告、促销活动、公共关系和人员销售。整合营销组合确保所有元素保持一致。
6. Operations Management | 运营管理
Operations management deals with the production of goods and services. Three main production methods: job production (one-off, customised, high quality, skilled labour), batch production (groups of similar items, flexible), and flow production (continuous, standardised, high volume, capital-intensive). The choice depends on the nature of the product, demand pattern, and available capital.
运营管理涉及商品和服务的生产。三种主要生产方式：单件生产（一次性、定制化、高质量、熟练劳动）、批量生产（同类物品成批生产，灵活）和流水生产（连续、标准化、大批量、资本密集型）。选择取决于产品性质、需求模式和可用资本。
Lean production aims to reduce waste and improve quality. Techniques include kaizen (continuous improvement), just-in-time (JIT) inventory control (materials arrive exactly when needed, reducing storage cost but requiring reliable suppliers), and total quality management (TQM) (everyone is responsible for quality).
精益生产旨在减少浪费和提高质量。技术包括改善（持续改进）、准时制（JIT）库存控制（材料在需要时恰好到达，降低存储成本但要求可靠的供应商）和全面质量管理（TQM）（每个人对质量负责）。
Break-even analysis helps a business understand how many units it must sell to cover total costs. Key formulas:
Break-even point (units) = Fixed Costs / (Selling Price per unit - Variable Cost per unit)
s) = Total Contribution - Fixed Costs. Margin of safety = Actual Sales - Break-even Sales.
Break-even charts visually show costs, revenue and profit/loss at different output levels. The method is useful for decision-making but assumes all output is sold and that costs are linear – these are limitations.
盈亏平衡分析帮助企业理解必须销售多少单位才能覆盖总成本。关键公式：
盈亏平衡点（单位） = 固定成本 / （单位售价 - 单位变动成本）
单位贡献 = 售价 - 变动成本。总贡献 = 总收入 - 总变动成本。利润（或亏损） = 总贡献 - 固定成本。安全边际 = 实际销售量 - 盈亏平衡销售量。
盈亏平衡图直观地显示了不同产出水平下的成本、收入和盈亏。该方法有助于决策，但假设所有产出都已售出且成本是线性的——这些都是局限性。
7. Human Resources | 人力资源
Human resource management (HRM) covers recruitment, selection, training, motivation, and employment law. Recruitment can be internal (promoting existing staff) or external (advertising outside). The process: job analysis, job description, person specification, advertising, shortlisting, interviews, tests, offer. Effective recruitment reduces labour turnover and improves productivity.
人力资源管理涵盖招聘、选拔、培训、激励和雇佣法律。招聘可以是内部（提拔现有员工）或外部（对外广告）。流程：工作分析、职位描述、人员规格、广告、筛选、面试、测试、录用通知。有效的招聘可降低劳动力流动率并提高生产率。
Training types: induction (introduction for new employees), on-the-job (learning while working), off-the-job (away from workplace e.g. college). Benefits of training: higher productivity, better quality, fewer accidents, greater motivation. However, training costs money and time, and workers may leave after being trained.
培训类型：入职培训（对新员工的介绍）、在职培训（边工作边学习）、脱产培训（离开工作场所，如大学学习）。培训的好处：更高的生产率、更好的质量、更少的事故、更强的动力。但培训花费金钱和时间，而且员工在接受培训后可能离职。
Motivation theories: Taylor (money motivates, piece rate), Maslow (hierarchy of human needs – physiological, safety, social, esteem, self-actualisation), Herzberg (two-factor theory: hygiene factors stop dissatisfaction, motivators give satisfaction). Financial motivators include wages, salaries, commission, profit-sharing, bonuses. Non-financial motivators include job enrichment, job rotation, teamworking, empowerment, and recognition.
激励理论：泰勒（金钱激励，计件工资）、马斯洛（需求层次——生理、安全、社交、尊重、自我实现）、赫茨伯格（双因素理论：保健因素消除不满，激励因素带来满意）。财务激励包括工资、薪金、佣金、利润分享、奖金。非财务激励包括工作丰富化、工作轮换、团队合作、授权和表彰。
8. Finance: Sources of Finance and Cash Flow | 财务：资金来源与现金流
Businesses need finance for different time periods. Short-term sources (under one year): overdraft (flexible but costly interest), trade credit (delaying payment to suppliers), factoring (selling invoices to a third party). Long-term sources: bank loans (fixed repayment schedule, interest), debentures (long-term loans to the public), share capital (selling shares – permanent capital but dividends are paid), retained profit (internal, no interest, but limited by profit levels).
企业需要不同时间段的融资。短期来源（一年以内）：透支（灵活但利息成本高）、商业信用（延迟支付供应商）、保理（将发票出售给第三方）。长期来源：银行贷款（固定还款计划、利息）、债券（对公众的长期借款）、股本（出售股份——永久性资本但需支付股息）、留存利润（内部、无利息、但受利润水平限制）。
Choosing the right source depends on the amount needed, the purpose, cost (interest), risk, and whether the owners want to retain control. For instance, issuing shares may dilute ownership but reduces debt risk.
选择合适的来源取决于所需金额、用途、成本（利息）、风险以及所有者是否希望保留控制权。例如，发行股票可能稀释所有权但降低债务风险。
Cash flow is the movement of money into and out of the business. A cash flow forecast estimates future receipts and payments. Regular cash flow problems occur when outflows are greater than inflows. A business can improve cash flow by reducing credit periods for customers, increasing supplier credit, leasing instead of buying, or cutting costs. Profit is not the same as cash: a profitable business can still fail if it lacks cash (insolvency).
现金流是资金进出企业的流动。现金流量预测估计未来的收入和支出。当流出大于流入时，就会出现持续的现金流问题。企业可以通过缩短客户信用期、增加供应商信用、租赁而非购买或削减成本来改善现金流。利润不等于现金：一家盈利的企业如果缺乏现金仍可能倒闭（破产）。
9. Financial Statements and Ratios | 财务报表与比率分析
The two main financial statements for a sole trader are the income statement and the statement of financial position (balance sheet). The income statement shows the profit or loss over a period:
Revenue - Cost of Sales = Gross Profit; Gross Profit - Expenses = Net Profit
s = Liabilities + Equity. Current assets include cash, inventory, trade receivables; non-current assets include buildings, machinery. Current liabilities are due within one year (overdraft, trade payables).
利润表显示一段时间内的利润或亏损：收入 - 销售成本 = 毛利；毛利 - 费用 = 净利润。销售成本 = 期初存货 + 采购 - 期末存货。资产负债表显示特定日期的资产、负债和所有者权益。资产 = 负债 + 所有者权益。流动资产包括现金、存货、应收账款；非流动资产包括厂房、机器。流动负债在一年内到期（透支、应付账款）。
Ratio analysis helps interpret financial performance:
| Ratio | Formula | Indicates / 指标意义 |
| Gross Profit Margin | (Gross Profit / Revenue) × 100 | Profitability after direct costs / 扣除直接成本后的盈利能力 |
| Net Profit Margin | (Net Profit / Revenue) × 100 | Overall profitability / 整体盈利能力 |
| Current Ratio | Current Assets / Current Liabilities | Liquidity (ideal ~1.5–2) / 流动性（理想 ~1.5–2） |
| Acid Test Ratio | (Current Assets - Inventories) / Current Liabilities | Stricter liquidity (excludes slow-moving stock) / 严格流动性（排除滞销库存） |
showing how efficiently the capital is used. Improving ratios may involve cost control, higher sales prices, better inventory management, or renegotiating loans.
ROCE（已用资本回报率）=（净利润 / 已用资本）× 100，显示资本的使用效率。改善比率可能涉及成本控制、提高售价、改进库存管理或重新谈判贷款。
10. External Influences on Business Activity | 商业活动的外部影响
Businesses operate within an external environment they cannot control. Economic factors include inflation (rising general prices erodes purchasing power and increases costs), unemployment, interest rates (higher rates raise borrowing cost and discourage investment), and exchange rates. A strong domestic currency makes exports dearer and imports cheaper, harming exporters but helping importers. Taxation policies and government spending also affect demand and costs.
企业在无法控制的外部环境中运营。经济因素包括通货膨胀（总体物价上涨侵蚀购买力并提高成本）、失业、利率（高利率增加借贷成本并抑制投资）和汇率。本币走强使出口更贵、进口更便宜，损害出口商但帮助进口商。税收政策和政府支出也影响需求和成本。
Businesses must consider stakeholder objectives. Stakeholders include owners (profit), employees (fair pay, job security), customers (quality, value), suppliers (regular orders, prompt payment), government (tax revenue, compliance), local community (environment, jobs), and pressure groups. Conflicts arise because their aims differ. A business must balance these interests – corporate social responsibility (CSR) involves acting ethically towards society and the environment.
企业必须考虑利益相关者目标。利益相关者包括所有者（利润）、员工（公平薪酬、工作保障）、顾客（质量、价值）、供应商（稳定订单、及时付款）、政府（税收、合规）、当地社区（环境、就业）以及压力团体。由于目标不同，会产生冲突。企业必须平衡这些利益——企业社会责任（CSR）涉及对社会和环境采取合乎道德的行动。
International trade and globalisation bring opportunities (new markets, cheaper supplies) and threats (more competition, cultural differences). Multinational companies (MNCs) operate in several countries, bringing investment and technology but also potential exploitation of labour and environmental damage. A business can grow internationally through exporting, franchising, licensing, or joint ventures.
国际贸易和全球化带来机遇（新市场、更便宜的供应）和威胁（更多竞争、文化差异）。跨国公司在多个国家运营，带来投资和技术，但也可能剥削劳动力和破坏环境。企业可以通过出口、特许经营、许可或合资等方式实现国际化成长。
