欢迎来到9年级WJEC商务复习指南。本文汇集了你需要掌握的所有重要主题，从理解什么是企业到探索融资与激励。每个部分都用中英双语呈现核心概念，帮助你在两种语言中掌握术语，并加深记忆以应对考试。
1. What is a Business? | 什么是企业？
A business is an organisation that produces goods or provides services to satisfy the needs and wants of individuals. Goods are tangible items you can touch, like a mobile phone or a loaf of bread. Services are intangible activities performed for you, such as a haircut or a train journey. The fundamental economic problem is that resources are scarce while human wants are unlimited, so businesses must decide how to allocate limited resources most efficiently.
企业是生产商品或提供服务以满足人们需求和欲望的组织。商品是你可以触摸的有形物品，如手机或面包。服务是为你完成的无形活动，如理发或火车旅行。基本的经济问题是资源稀缺而人类的欲望无限，因此企业必须决定如何最有效地分配有限的资源。
Businesses add value by turning inputs (raw materials, labour, capital) into outputs that customers are willing to pay for. The difference between the cost of inputs and the selling price of outputs is the added value. For example, a baker buys flour, water and yeast for a low cost, transforms them into bread, and sells it at a higher price.
企业通过将投入（原材料、劳动力、资本）转化为顾客愿意购买的产品来增加价值。投入的成本与产品售价之间的差额就是附加价值。例如，面包师以低成本购买面粉、水和酵母，将其转化为面包，再以更高的价格出售。
2. Entrepreneurship and Enterprise | 企业家精神与企业
An entrepreneur is someone who takes the financial and personal risk of starting a new business, hoping to make a profit. Enterprise refers to the skills and mindset needed to spot a business opportunity and pull together land, labour and capital to pursue it. Successful entrepreneurs often show creativity, a willingness to take calculated risks, determination and the ability to lead others.
企业家是承担财务和个人风险创办新企业并期望盈利的人。企业精神是指识别商业机会并整合土地、劳动力和资本来追求这一机会所需的技能和心态。成功的企业家往往表现出创造力、愿意承担经过计算的风险、决心以及领导他人的能力。
Why is enterprise important? It drives innovation, creates jobs and can bring new products to the market that improve people's lives. Many of today's most influential companies began when an entrepreneur identified a gap in the market and had the courage to act on the idea.
为什么企业精神很重要？它推动创新、创造就业，并能将改善人们生活的新产品带入市场。如今许多最具影响力的公司都始于企业家发现市场缺口并有勇气将想法付诸实施。
3. Business Aims and Objectives | 商业目标与具体目标
Aims are the long-term general goals a business works towards, such as survival, growth, profit maximisation or becoming more environmentally friendly. Objectives are shorter-term, specific targets that help the business achieve its aims. They are often written using the SMART criteria — Specific, Measurable, Achievable, Relevant and Time-bound.
目标是企业努力实现的长期总体目的，例如生存、发展、利润最大化或变得更加环保。具体目标是帮助实现这些总体目标的短期、具体指标。它们通常按照SMART原则来制定——具体、可衡量、可实现、相关且有时限。
For example, a new cafe might have the aim of survival and set an objective to sell 200 cups of coffee per day within the first three months. Larger businesses may focus on profit maximisation as an aim, with objectives like increasing market share by 5% over the next year.
例如，一家新咖啡馆的目标可能是生存，并设定一个具体目标：在头三个月内每天卖出200杯咖啡。较大的企业可能以利润最大化为总体目标，并设定如下具体目标：在未来一年内将市场份额提高5%。
4. Stakeholders and Their Interests | 利益相关者及其利益
Stakeholders are any individuals or groups who have an interest in the activities of a business. Internal stakeholders include owners, managers and employees. External stakeholders include customers, suppliers, the local community, the government and pressure groups.
利益相关者是对企业活动有利害关系的任何个人或群体。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、当地社区、政府以及压力团体。
Stakeholders often have different, sometimes conflicting, objectives. Owners want high profits, employees want secure jobs and fair pay, customers want low prices and high quality, and the local community wants a clean environment and job opportunities. Businesses must learn how to balance these interests.
利益相关者的目标常常不同，有时相互冲突。所有者希望高利润，员工希望工作有保障和公平薪酬，客户希望低价高质，而当地社区希望环境清洁和就业机会。企业必须学会平衡这些利益。
5. Types of Business Ownership | 企业所有权类型
The main forms of private-sector ownership are sole traders, partnerships, private limited companies (Ltd) and public limited companies (plc). A sole trader is a business owned and controlled by one person, who has unlimited liability — meaning personal assets can be seized to pay business debts. A partnership involves 2–20 partners who share decisions and profits, also with unlimited liability.
私营部门所有权的主要形式有个体经营、合伙企业、私营有限公司（Ltd）和上市有限公司（plc）。个体经营是由一人拥有和控制的企业，具有无限责任——这意味着个人财产可能被用来偿还企业债务。合伙企业涉及2至20名合伙人共同决策和分享利润，同样承担无限责任。
Limited companies are separate legal entities from their owners. A private limited company (Ltd) sells shares privately, often to family and friends, and offers limited liability — shareholders only lose the money they invested. A public limited company (plc) can sell shares to the general public on the stock exchange, which helps raise large amounts of capital but comes with stricter regulations.
有限公司是独立于其所有者的法律实体。私营有限公司（Ltd）私下向家人和朋友出售股份，提供有限责任——股东仅损失其投资金额。上市有限公司（plc）可在股票交易所向公众出售股份，这有助于筹集大量资金，但也须遵守更严格的法规。
6. Business Planning | 商业计划书
A business plan is a written document that sets out the business idea, its aims, how it will operate, and detailed financial forecasts. Key sections include an executive summary, description of the product or service, market research, marketing strategy, operations plan, and financial projections such as cash flow and profit forecasts.
商业计划书是一份书面文件，阐述商业理念、目标、运营方式及详细的财务预测。关键部分包括摘要、产品或服务描述、市场调研、营销策略、运营计划以及现金流和利润预测等财务预测。
Writing a business plan helps entrepreneurs clarify their thinking, identify potential problems, and set clear targets. It is also essential when applying for bank loans or seeking investment, as lenders and investors will want to see a solid plan before committing any money.
撰写商业计划书有助于企业家理清思路、识别潜在问题并设定明确目标。在申请银行贷款或寻求投资时，它也是必不可少的，因为贷款人和投资者在投入资金前会希望看到一份扎实的计划。
7. The Marketing Mix: The 4Ps | 市场营销组合：4Ps
The marketing mix describes the key elements that a business can control to influence consumers to buy its products. It is commonly known as the 4Ps: Product, Price, Place and Promotion. Product covers design, features, quality, branding and packaging. Price includes pricing strategies such as cost-plus, penetration or premium pricing, and how price affects demand.
营销组合描述了企业可以控制以影响消费者购买其产品的关键要素，通常被称为4Ps：产品、价格、渠道和促销。产品涵盖设计、特色、质量、品牌和包装。价格包括成本加成定价、渗透定价或高价定价等定价策略，以及价格如何影响需求。
Place refers to how the product reaches the customer — through retail stores, online platforms, wholesalers or direct selling. Promotion covers all methods used to communicate with customers, such as advertising, public relations, sales promotions and social media marketing. An effective marketing mix ensures all four elements work together to meet customer needs.
渠道指产品如何到达顾客——通过零售店、线上平台、批发商或直销。促销涵盖用于与顾客沟通的所有方法，如广告、公关、促销活动和社交媒体营销。有效的营销组合确保四个要素协同作用，满足顾客需求。
8. Market Research | 市场调研
Market research gathers information about consumers, competitors and the overall market to help businesses make informed decisions. Primary research collects brand-new data directly from the source through methods such as surveys, interviews, focus groups and observations. Secondary research uses data that already exists, such as government statistics, market reports, articles and internet research.
市场调研收集有关消费者、竞争对手和整体市场的信息，帮助企业做出明智决策。一手调研直接从源头收集全新数据，方法包括问卷调查、访谈、焦点小组和观察。二手调研使用现有数据，如政府统计数据、市场报告、文章和互联网研究。
Primary research is specific to the business's needs but can be time-consuming and expensive. Secondary research is often cheaper and quicker, but the information may be outdated or not perfectly suited to the business's exact requirements. Most businesses use a mix of both.
一手调研针对企业特定需求，但可能耗时且昂贵。二手调研通常更便宜、更快捷，但信息可能过时或不完全符合企业的确切要求。大多数企业会两者结合使用。
9. Sources of Finance | 融资来源
Businesses need finance for starting up, expanding, purchasing equipment or managing day‑to‑day cash flow. Internal sources come from within the business, such as retained profit (profits reinvested rather than paid out) and the sale of unwanted assets. External sources are raised from outside, including bank loans, overdrafts, trade credit, leasing and venture capital.
企业需要资金用于启动、扩张、购买设备或管理日常现金流。内部来源来自企业内部，如留存利润（再投资而非分配的利润）和出售闲置资产。外部来源从企业外部筹集，包括银行贷款、透支、贸易信用、租赁和风险资本。
Short-term finance, like an overdraft or trade credit, is used to cover temporary cash shortages and is usually repaid within a year. Long-term finance, such as a bank loan or share capital, is used for major investments and is repaid over several years. Choosing the right source depends on the amount needed, the cost, the risk and the period of repayment.
短期融资，如透支或贸易信用，用于弥补暂时的现金短缺，通常一年内偿还。长期融资，如银行贷款或股本，用于重大投资，偿还期长达数年。选择合适的来源取决于所需金额、成本、风险和偿还期限。
10. Costs, Revenue and Profit | 成本、收入与利润
Businesses classify costs into fixed costs and variable costs. Fixed costs, such as rent and salaries, do not change with the level of output. Variable costs, like raw materials and packaging, rise and fall directly with production volume. Total costs are the sum of fixed and variable costs.
企业将成本分为固定成本和可变成本。固定成本，如租金和工资，不随产量水平变化。可变成本，如原材料和包装，直接随产量增减。总成本是固定成本与可变成本之和。
Total Costs = Fixed Costs + Variable Costs
Revenue is the income earned from selling goods or services. It is calculated by multiplying the selling price per unit by the number of units sold. Profit is the positive difference between total revenue and total costs. If total costs exceed total revenue, the business makes a loss.
收入是销售商品或服务所赚取的款项，由单位售价乘以销售数量计算得出。利润是总收入与总成本之间的正差额。如果总成本超过总收入，企业就会亏损。
Revenue = Selling Price per Unit × Quantity Sold
Profit = Total Revenue − Total Costs
For example, if a business sells 500 units at £10 each, revenue is £5,000. If total costs are £3,500, profit is £1,500. Understanding these calculations helps managers set prices, control costs and plan for growth.
例如，某企业以每件10英镑售出500件，收入为5,000英镑。若总成本为3,500英镑，利润则为1,500英镑。理解这些计算有助于管理者制定价格、控制成本和规划增长。
11. Break-even Analysis | 盈亏平衡分析
Break-even analysis shows how many units a business must sell to cover all costs. The break-even point is where total revenue equals total costs — the business makes neither a profit nor a loss. The formula to calculate break-even output is:
盈亏平衡分析显示企业必须销售多少单位才能覆盖全部成本。盈亏平衡点是总收入等于总成本的点——企业既不盈利也不亏损。计算盈亏平衡产量的公式是：
Break-even Output = Fixed Costs ÷ (Selling Price per Unit − Variable Cost per Unit)
The term (Selling Price per Unit − Variable Cost per Unit) is called the contribution per unit — the amount each sale contributes towards covering fixed costs. Once fixed costs are covered, further sales generate profit. Drawing a break-even chart with cost and revenue lines helps visualise the break-even point and the margin of safety.
（单位售价 − 单位可变成本）这一项称为单位贡献——每笔销售用于覆盖固定成本的金额。一旦固定成本被覆盖，后续销售便开始产生利润。绘制包含成本线和收入线的盈亏平衡图有助于直观显示盈亏平衡点和安全边际。
12. Human Resources and Motivation | 人力资源与激励
Human resources (HR) is the function that manages people within a business, from recruitment and selection to training and performance management. Motivating employees is crucial because a well‑motivated workforce tends to be more productive, produce higher quality work and stay loyal to the company. Methods of motivation can be financial, such as bonuses, commission and profit sharing, or non‑financial, such as praise, job enrichment and promotion opportunities.
人力资源（HR）是管理企业内人员的职能，涵盖从招聘、选拔到培训和绩效管理的全过程。激励员工至关重要，因为积极性高的员工队伍往往更高效、产出质量更高，并且对公司更忠诚。激励方法可以是金钱型的，如奖金、佣金和利润分享，也可以是非金钱型的，如表扬、工作丰富化和晋升机会。
Two well‑known theories of motivation are Maslow's hierarchy of needs and Herzberg's two‑factor theory. Maslow suggested workers must satisfy lower‑level needs, like pay and safety, before moving to higher‑level needs such as recognition and self‑fulfilment. Herzberg distinguished between hygiene factors (salary, working conditions) that prevent dissatisfaction, and motivators (achievement, responsibility) that truly drive staff to excel.
两个著名的激励理论是马斯洛的需求层次理论和赫茨伯格的双因素理论。马斯洛认为员工必须先满足薪酬和安全等低层次需求，然后才能追求认可和自我实现等高层次需求。赫茨伯格区分了防止不满的保健因素（如工资、工作条件）和真正驱使员工追求卓越的激励因素（如成就、责任感）。
