1. The Nature of Business Activity | 商业活动的本质
Business activity exists to satisfy the needs and wants of consumers by producing goods and providing services. Since resources such as raw materials, labour and machinery are scarce, businesses must decide how to use them most effectively.
商业活动通过生产商品和提供服务来满足消费者的需求与欲望。由于原材料、劳动力和机器等资源是稀缺的，企业必须决定如何最有效地利用它们。
The basic economic problem is that people have unlimited wants but limited resources. This forces every business to answer three fundamental questions: what to produce, how to produce, and for whom to produce. The concept of opportunity cost then arises – the next best alternative given up when a choice is made.
基本经济问题是人们的欲望无限而资源有限。这迫使每个企业回答三个基本问题：生产什么、如何生产以及为谁生产。于是便产生了机会成本的概念——即做出选择时所放弃的次优替代选项。
Adding value is a key business aim. It means increasing the worth of a product by transforming inputs into outputs that customers are prepared to pay more for. For example, a bakery adds value by turning flour, water and yeast into bread. The difference between the selling price and the cost of bought-in materials is the added value.
增加价值是一个关键的商业目标。它指通过将投入转化为顾客愿意支付更高价格的产出来提高产品的价值。例如，面包店通过将面粉、水和酵母制成面包来增加价值。售价与购入材料成本之间的差额就是增加价值。
The four factors of production are land (natural resources), labour (human effort), capital (machinery, tools, finance) and enterprise (the risk-taking ability of entrepreneurs who combine the other three factors). Without enterprise, the other resources would not be coordinated into a functioning business.
四大生产要素是土地（自然资源）、劳动力（人力）、资本（机器、工具、资金）和企业才能（企业家承担风险、整合其他三种要素的能力）。没有企业才能，其他资源就无法被协调成一个运作的业务。
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, e.g. farming, mining, fishing. The secondary sector manufactures finished products, e.g. car assembly, textile production. The tertiary sector provides services, e.g. retail, banking, tourism. As an economy develops, the relative importance of the tertiary sector tends to grow.
企业可按其运营所处的经济部门分类。第一产业提取原材料，如农业、采矿、渔业。第二产业制造成品，如汽车装配、纺织生产。第三产业提供服务，如零售、银行、旅游业。随着经济发展，第三产业的相对重要性通常会上升。
Another important classification is based on ownership. Private sector businesses are owned by individuals or groups aiming to make a profit. Public sector organisations are owned and operated by the government, often providing essential services such as education, healthcare and street lighting, with objectives more focused on social welfare than on profit.
另一种重要的分类基于所有权。私营部门企业由个人或团体拥有，以盈利为目的。公共部门组织由政府拥有和运营，通常提供教育、医疗和街道照明等基本服务，其目标更侧重于社会福利而非利润。
| Private Sector | Public Sector |
| Owned by private individuals or shareholders | Owned by the government |
| Main aim: profit maximisation | Main aim: provide essential services |
| Examples: sole traders, partnerships, private limited companies | Examples: state schools, public hospitals, police services |
The table summarises the key differences between the private and public sectors. Private firms react quickly to market demand, while public bodies often face political considerations. In many mixed economies both sectors coexist and sometimes compete.
该表格总结了私营与公共部门的主要区别。私营企业迅速响应市场需求，而公共机构常常要考虑政治因素。在许多混合经济体中，两个部门并存，有时还会相互竞争。
3. Enterprise, Entrepreneurs and Business Growth | 创业、企业家与企业成长
An entrepreneur is an individual who takes the risk of starting and running a business, combining the other factors of production. Successful entrepreneurs often show qualities such as innovation, determination, ability to identify opportunities, and willingness to take calculated risks.
企业家是承担创业和经营风险、组合其他生产要素的个人。成功的企业家往往展现出创新精神、决心、识别机遇的能力以及承担可计算风险的意愿。
A detailed business plan is essential for any new venture. It usually contains the business idea, market research, financial forecasts, marketing strategy and operational details. A well-written plan helps secure finance from banks or investors and guides the entrepreneur through the early stages.
一份详细的商业计划书对任何新创企业都至关重要。它通常包含商业创意、市场调研、财务预测、营销策略和运营细节。精心撰写的计划有助于从银行或投资者那里获取资金，并指导企业家度过早期阶段。
Business growth can be achieved internally or externally. Internal (organic) growth involves expanding the business's own activities, such as opening new branches or launching new products. External growth takes place through mergers or acquisitions. A merger is when two firms agree to combine, while an acquisition (takeover) happens when one firm buys control of another.
企业成长可以通过内部或外部方式实现。内部（有机）增长是指通过扩大自身经营活动实现发展，如开设新分店或推出新产品。外部增长通过合并或收购实现。合并是指两家公司同意联合，而收购（接管）则是指一家公司购买另一家公司的控制权。
Integration can be horizontal (same industry and stage of production), vertical backward (taking control of a supplier) or vertical forward (taking control of a customer). Diversification occurs when a business expands into completely different products or markets, spreading risk.
整合可以是横向的（同行业同生产阶段）、纵向后向（控制供应商）或纵向前向（控制客户）。当企业扩展到完全不同的产品或市场时就出现了多元化经营，从而分散风险。
4. Business Objectives and Stakeholders | 商业目标与利益相关者
Businesses set objectives to give direction and measure performance. Common objectives include survival (especially for start-ups), profit maximisation, growth, increasing market share, and providing a service to the community. Social enterprises combine business methods with social aims, reinvesting profits to achieve their mission.
企业设定目标是为了明确方向和衡量业绩。常见目标包括生存（尤其是初创企业）、利润最大化、成长、提高市场份额以及为社区提供服务。社会企业将商业手段与社会目标相结合，将利润再投资以实现其使命。
Business objectives can change over time and may conflict with each other. For instance, pursuing growth might reduce short-term profits because of heavy investment. A small family business might prioritise a stable income over rapid expansion.
商业目标会随时间变化，并且可能相互冲突。例如，追求增长可能会因大量投资而减少短期利润。一家小型家族企业可能会优先考虑稳定收入而非快速扩张。
Stakeholders are individuals or groups with an interest in the activities of a business. Internal stakeholders include owners, managers and employees. External stakeholders comprise customers, suppliers, the government, the local community and even competitors. Each group has different objectives – owners want high dividends, employees want secure jobs and fair pay, while the government expects tax revenue and legal compliance.
利益相关者是与企业活动有利益关系的个人或群体。内部利益相关者包括所有者、管理者和员工。外部利益相关者包括客户、供应商、政府、当地社区甚至竞争对手。每个群体有不同的目标——所有者希望高股息，员工期望稳定工作和公平薪酬，而政府则要求税收和守法经营。
Stakeholder conflict frequently occurs. For example, paying higher wages to workers can reduce profit available for shareholders. Building a factory may create jobs but cause noise pollution, upsetting the local community. Businesses must balance these competing interests.
利益相关者冲突经常发生。例如，支付工人更高工资会减少可供股东分配的利润。建立工厂可能会创造就业机会，但也会产生噪音污染，引起当地社区不满。企业必须平衡这些相互矛盾的利益。
5. Business Organisation and Structure | 企业组织与结构
The legal form of a business affects its ownership, liability and ability to raise capital. In the private sector, sole traders and partnerships have unlimited liability, meaning the owners are personally responsible for all business debts. Limited companies, on the other hand, offer limited liability – shareholders only lose the amount they invested.
企业的法律形式影响其所有权、责任和筹集资金的能力。在私营部门，个体经营者和合伙制企业承担无限责任，即所有者对所有企业债务负有个人责任。而有限责任公司提供有限责任——股东仅损失其投资金额。
Private limited companies (Ltd) cannot sell shares to the general public, whereas public limited companies (PLC) can be listed on a stock exchange. Other forms include franchises, where a franchisee pays to use an established brand and business model, and joint ventures, where two or more businesses collaborate on a specific project.
私人有限公司 (Ltd) 不能向公众出售股份，而上市公司 (PLC) 可以在证券交易所上市。其他形式包括特许经营，即加盟商付费使用已建立的品牌和商业模式，以及合资企业，即两个或多个企业就特定项目展开合作。
| Type | Ownership & Liability | Control & Capital |
| Sole trader | One owner; unlimited liability | Full control; limited capital from savings and loans |
| Partnership | 2–20 partners; unlimited liability (usually) | Shared control; more capital than sole trader |
| Private Ltd | Shareholders; limited liability | Board of directors; shares cannot be sold publicly |
| Public Ltd (PLC) | Shareholders; limited liability | Shares traded on stock exchange; higher capital raising ability |
The table above contrasts the key features of common business ownership forms. Choosing the right structure depends on factors such as the need for capital, the desire for control and the willingness to accept personal risk.
上表对比了常见企业所有权形式的关键特征。选择合适结构取决于资本需求、对控制权的渴望以及承担个人风险的意愿等因素。
Internal organisation can be represented through an organisational chart. A tall structure has many layers of management, with a long chain of command and narrow spans of control. A flat structure has fewer layers, wider spans of control and often faster communication. Functional structures group workers by specialty, such as marketing, finance and operations.
内部组织可通过组织结构图来表示。高耸型结构有多层管理层级，指挥链长，控制幅度窄。扁平型结构层级较少，控制幅度宽，沟通通常更快。职能型结构按专业将员工分组，如市场营销、财务和运营。
6. Introduction to Marketing | 市场营销导论
Marketing is about identifying and satisfying customer needs profitably. A market-oriented business designs its products based on consumer research, while a product-oriented business focuses on developing high-quality products and then trying to sell them. Most modern businesses adopt a market orientation to remain competitive.
市场营销是识别并满足客户需求以获取利润的过程。市场导向型企业基于消费者调研设计产品，而产品导向型企业则专注于研发高质量产品再设法将其售出。大多数现代企业采用市场导向以保持竞争力。
Market segmentation divides potential customers into distinct groups with similar characteristics. Common bases include age, gender, income, geographic location and lifestyle. Segmentation allows businesses to target specific groups with tailored marketing strategies, rather than trying to appeal to everyone.
市场细分将潜在客户划分为具有相似特征的不同群体。常见依据包括年龄、性别、收入、地理位置和生活方式。细分使企业能够针对特定群体制定量身定做的营销策略，而不是试图吸引所有人。
Market research gathers information about customers, competitors and market trends. Primary research collects first-hand data through surveys, interviews and focus groups. Secondary research uses existing data from reports, government statistics or the internet. Primary data is usually more specific but also more expensive and time-consuming.
市场调研收集关于顾客、竞争对手和市场趋势的信息。一手调研通过问卷、访谈和焦点小组收集第一手数据。二手调研利用报告、政府统计资料或互联网上的现有数据。一手数据通常更具体，但也更昂贵、更耗时。
The marketing mix describes the key elements used to influence customer purchasing decisions. It is often summarised as the 4Ps: Product (design, features, packaging), Price (pricing strategies), Place (distribution channels) and Promotion (advertising, public relations, sales promotions). All four elements must be carefully coordinated to create a consistent brand message.
营销组合描述了用来影响顾客购买决策的关键元素。它常被概括为4P：产品（设计、特性、包装）、价格（定价策略）、渠道（分销渠道）和促销（广告、公关、销售促进）。所有四个要素都必须精心协调，以传递一致的品牌信息。
7. Operations Management Basics | 运营管理基础
Operations management is concerned with the production of goods and services efficiently. The three main production methods are job production (making one-off, customised items), batch production (producing a set quantity of identical products at a time) and flow production (continuous, large-scale production on a moving line).
运营管理关注高效地生产商品和服务。三种主要生产方式是定制生产（制作一次性的定制物品）、批量生产（一次性生产一定数量的相同产品）和流水线生产（在移动生产线上进行连续、大规模生产）。
Job production offers high quality and flexibility but tends to be slow and costly. Batch production balances some flexibility with efficiency but can involve downtime between batches. Flow production achieves low unit costs and consistent quality, yet it requires high capital investment and is inflexible.
定制生产提供高质量和灵活性，但往往速度慢且成本高。批量生产在灵活性和效率之间取得一定平衡，但批次之间可能出现停工时间。流水线生产实现了低单位成本和一致的质量，但需要高额资本投入且缺乏灵活性。
Inventory management aims to hold the right quantity of stock. Too much stock ties up cash and storage space; too little can halt production or lead to lost sales. Just-in-time (JIT) is a lean approach where materials arrive exactly when needed, minimising waste and holding costs. It relies heavily on reliable suppliers and accurate demand forecasts.
库存管理旨在持有适当数量的库存。库存过多会占用资金和仓储空间；过少可能导致生产中断或错失销售。准时制 (JIT) 是一种精益方法，材料在恰好需要时到达，最大程度减少浪费和持有成本。它高度依赖可靠的供应商和准确的需求预测。
Quality is vital for customer satisfaction and reputation. Quality control involves inspecting finished products to detect defects. Quality assurance, on the other hand, builds quality into the production process itself, setting standards at every stage to prevent errors rather than just catching them afterwards.
质量对客户满意度和企业声誉至关重要。质量控制涉及检验成品以发现缺陷。而质量保证则从生产流程本身入手，在每个阶段设定标准，以预防错误，而不仅仅是在事后发现错误。
8. Financial Fundamentals | 财务基础知识
Financial information helps businesses plan, monitor and control their operations. Revenue is the income from selling goods or services. Costs are classified into fixed costs (rent, salaries – unchanged with output) and variable costs (raw materials, packaging – vary directly with output). Total costs equal fixed costs plus variable costs.
财务信息有助于企业规划、监督和控制运营。收入是销售商品或服务所得。成本分为固定成本（租金、工资——不随产量变化）和可变成本（原材料、包装——随产量直接变化）。总成本等于固定成本加可变成本。
Profit is the reward for taking risk and is calculated as: Profit = Total revenue – s exceed total revenue. Businesses monitor their profit margin to assess financial health.
利润是承担风险的回报，计算公式为：利润 = 总收入 – 总成本。当总成本超过总收入时便出现亏损。企业监控利润率以评估财务健康状况。
A crucial decision-making tool is break-even analysis. The break-even point is where total revenue equals total costs, meaning the business makes neither profit nor loss. It can be calculated using the formula below:
盈亏平衡分析是一项重要的决策工具。盈亏平衡点是总收入与总成本相等的点，意味着企业既不盈利也不亏损。它可以用以下公式计算：
Break-even output = Fixed costs ÷ (Selling price per unit − Variable cost per unit)
盈亏平衡产量 = 固定成本 ÷ (单位售价 − 单位可变成本)
Cash flow is the movement of money into and out of a business. A cash flow forecast predicts monthly inflows (e.g. from sales, capital injections) and outflows (e.g. wages, rent, supplier payments). A business can be profitable but still fail if it runs out of cash – this is called insolvency. Careful cash management ensures the business can meet its short-term obligations.
现金流是指资金流入和流出企业的运动。现金流预测会预估每月现金流入（如销售收入、资本注入）和现金流出（如工资、租金、供应商付款）。一家企业即使盈利，如果现金耗尽也可能失败——这被称为资不抵债。审慎的现金管理确保企业能够履行其短期支付义务。
9. External Influences on Business | 外部环境影响
Businesses do not operate in isolation; they are influenced by the external environment. Economic factors include changes in interest rates, exchange rates, inflation and unemployment. For example, rising interest rates raise borrowing costs and reduce consumer spending, which can lower demand for many products.
企业并非在真空中运营；它们受到外部环境的影响。经济因素包括利率、汇率、通货膨胀和失业率的变化。例如，利率上升会提高借贷成本、减少消费支出，从而可能降低对许多产品的需求。
Legal constraints require businesses to comply with laws on minimum wage, health and safety, consumer protection and employment rights. Non-compliance can lead to fines, legal action and reputational damage. Meeting legal standards also increases costs, but it protects workers and customers.
法律约束要求企业遵守关于最低工资、健康与安全、消费者保护和雇佣权利的法律。不合规可能导致罚款、法律诉讼和声誉损害。达到法律标准也会增加成本，但它保护了员工和顾客。
Technological change creates both opportunities and threats. E-commerce allows firms to reach global markets 24/7, while automation improves productivity but may require workforce retraining. Businesses that fail to adopt new technology risk losing competitiveness.
技术变革既带来机遇也构成威胁。电子商务使企业能够全天候接触全球市场，而自动化提高生产率，但可能需要对员工进行再培训。未能采用新技术的企业有丧失竞争力的风险。
Social and demographic shifts, such as ageing populations, more diverse workforces and growing environmental awareness, influence what consumers buy and how businesses operate. Firms respond by offering sustainable products and promoting inclusive workplace policies.
社会与人口结构变化，例如人口老龄化、劳动力更加多元化以及环保意识日益增强，会影响消费者的购买选择和企业的经营方式。企业通过提供可持续产品和推行包容性职场政策来应对。
The competitive environment shapes strategy. When many rivals sell similar products, businesses must differentiate themselves through quality, price or branding. Monopolies – markets dominated by a single supplier – can set higher prices, but often face regulatory scrutiny.
竞争环境塑造战略。当许多竞争对手销售相似产品时，企业必须通过质量、价格或品牌来凸显自身优势。垄断——由单一供应商主导的市场——可以设定更高价格，但通常会受到监管审查。
10. Ethics and Globalisation | 商业伦理与全球化
Business ethics refer to the moral principles that guide decision-making. Ethical issues include avoiding child labour, ensuring fair trade prices for suppliers in developing countries, and reducing environmental impact. Acting ethically can improve a firm's reputation and employee motivation, though it may raise costs in the short term.
商业伦理是指指导决策的道德原则。伦理问题包括避免使用童工、确保为发展中国家的供应商提供公平贸易价格以及减少环境影响。遵守道德行为可以提高企业声誉和员工积极性，尽管短期内可能会增加成本。
Sustainability means meeting present needs without compromising the ability of future generations to meet theirs. Businesses adopt sustainable practices such as using renewable energy, designing recyclable packaging and minimising waste. Many consumers now prefer brands that demonstrate genuine environmental commitment.
可持续发展是指满足当代需求而不损害后代满足其需求的能力。企业采用可持续实践，例如使用可再生能源、设计可回收包装和尽量减少废弃物。如今许多消费者更青睐那些展现出真正环保承诺的品牌。
Globalisation is the increasing integration of world economies through trade, investment and technology. Multinational companies (MNCs) operate in multiple countries, bringing benefits like job creation, skills transfer and wider product choice. However, critics argue that MNCs can exploit low-wage labour, damage local cultures and contribute to environmental harm.
全球化是通过贸易、投资和技术使世界经济日益一体化的过程。跨国公司 (MNCs) 在多个国家运营，带来创造就业
