1. What is Business Activity? | 什么是商业活动？
Business activity involves producing goods and services to satisfy people’s needs and wants. Needs are things essential for survival, such as food, water and shelter. Wants are desires that make life more comfortable, like smartphones or holidays.
商业活动指生产商品和服务以满足人们的需求和欲望。需求是生存所必需的，如食物、水和住所。欲望是让生活更舒适的渴望，例如智能手机或度假。
Because resources are limited, we face scarcity. This forces individuals, businesses and governments to make choices. The opportunity cost is the next best alternative given up when a decision is made.
由于资源有限，我们面临稀缺性。这迫使个人、企业和政府做出选择。机会成本就是做决定时放弃的次优选择。
Businesses add value by transforming raw materials into finished products. For example, a carpenter turns wood into furniture, which sells for more than the cost of the wood. This added value is essential for profit.
企业通过将原材料转化为成品来增加价值。例如，木匠把木材制成家具，售价高于木材成本。这种附加值对盈利至关重要。
2. Classification of Businesses | 企业分类
Businesses can be classified into three sectors: primary, secondary and tertiary. The primary sector extracts raw materials, such as farming, fishing and mining. The secondary sector manufactures goods from raw materials, like car assembly or baking. The tertiary sector provides services, including retail, transport and banking.
企业可分为三个部门：第一产业、第二产业和第三产业。第一产业开采原材料，如农业、渔业和采矿业。第二产业用原材料制造商品，如汽车装配或烘焙。第三产业提供服务，包括零售、运输和银行。
In many developing economies, the primary sector is the largest employer. As economies develop, the secondary sector grows, and later the tertiary sector becomes dominant. This shift is known as structural change.
在许多发展中经济体，第一产业是最大的雇主。随着经济发展，第二产业增长，之后第三产业占主导地位。这种转变称为结构变化。
Businesses also vary in size. We can measure size by number of employees, value of output, capital invested or market share. A small local shop and a multinational corporation differ greatly in scale.
企业规模也有差异。我们可以通过员工数量、产值、投入资本或市场份额来衡量规模。一家当地小商店和一家跨国公司规模差异巨大。
3. Business Objectives | 商业目标
Business objectives are the goals a business aims to achieve. They provide direction and a way to measure success. Common objectives include profit maximisation, growth, increasing market share and providing a service to the community.
商业目标是企业希望达到的目标。它们提供方向并衡量成功。常见目标包括利润最大化、成长、增加市场份额以及为社区提供服务。
Profit is often the main objective for private sector businesses. It is calculated as total revenue minus total costs. However, newly established businesses may focus on survival in their early years.
利润通常是私营企业的主要目标。它等于总收入减去总成本。然而，新成立的企业可能在前几年专注于生存。
Social enterprises and public sector organisations have different aims. They prioritise social, environmental or community benefits over making a profit. A charity’s objective might be to reduce homelessness, not to earn a surplus.
社会企业和公共部门组织有不同的目标。它们优先考虑社会、环境或社区效益，而非盈利。慈善机构的目标可能是减少无家可归现象，而不是赚取盈余。
4. Stakeholders | 利益相关者
A stakeholder is any individual or group affected by or having an interest in a business’s activities. Internal stakeholders include owners, managers and employees. External stakeholders include customers, suppliers, the government, local community and pressure groups.
利益相关者是指受企业活动影响或对其有利益的任何个人或群体。内部利益相关者包括所有者、经理和员工。外部利益相关者包括客户、供应商、政府、当地社区和压力团体。
Different stakeholders often have conflicting objectives. For example, owners want higher profits, which might lead to lower wages. Employees want higher pay, which reduces profit. A business must try to balance these interests.
不同利益相关者常有冲突的目标。例如，所有者希望更高的利润，这可能导致工资降低。员工希望更高的报酬，这会减少利润。企业必须尽量平衡这些利益。
The local community may be concerned about pollution and noise from a factory. The government wants businesses to create jobs and pay taxes. Understanding stakeholder needs helps a business make sustainable decisions.
当地社区可能担心工厂的污染和噪音。政府希望企业创造就业并缴纳税款。理解利益相关者的需求有助于企业做出可持续的决策。
5. Types of Business Organisation | 企业组织形式
Businesses can be set up in different legal forms. A sole trader is owned and run by one person. It is easy to set up but the owner has unlimited liability, meaning personal assets are at risk if the business fails.
企业可以以不同的法律形式成立。个体工商户由一个人拥有和经营。成立容易，但所有者承担无限责任，意味着如果企业失败，个人资产面临风险。
A partnership has two or more owners who share profits, risks and decision-making. Partners also usually have unlimited liability. A limited partnership allows some partners limited liability, but they cannot manage the business.
合伙企业有两个或以上的所有者，共享利润、风险和决策。合伙人通常也承担无限责任。有限合伙允许部分合伙人承担有限责任，但他们不能管理企业。
Private limited companies (Ltd) and public limited companies (PLC) are incorporated businesses. Shareholders own the company and have limited liability, so they can only lose the amount they invested. A PLC can sell shares to the public on the stock exchange, while an Ltd cannot.
私人有限公司和公众有限公司是法人企业。股东拥有公司并承担有限责任，因此他们最多损失投资金额。公众有限公司可在证券交易所向公众发行股票，而私人有限公司不能。
Other forms include franchises, where a franchisee pays to use the brand and business model of a franchisor, and joint ventures, where two or more businesses collaborate on a specific project while remaining separate entities.
其他形式包括特许经营，加盟商付费使用特许人的品牌和商业模式；以及合资企业，两个或多个企业为特定项目合作，但保持独立实体。
6. Marketing Basics | 市场营销基础
Marketing is about identifying and satisfying customer needs profitably. It involves market research to understand what customers want and the marketing mix to deliver value. The classic marketing mix is the 4Ps: Product, Price, Place and Promotion.
市场营销是以盈利方式识别并满足客户需求。它包括了解客户需求的市场调研，以及传递价值的营销组合。经典的营销组合是4P：产品、价格、渠道和促销。
A product can be a good or a service. Businesses must consider design, quality, brand name and packaging. A successful product solves a problem or fulfils a desire better than competitors’ offerings.
产品可以是商品或服务。企业必须考虑设计、质量、品牌名称和包装。成功的产品能比竞争对手更好地解决问题或满足欲望。
Pricing strategies include cost-plus pricing, where a mark-up is added to the cost of production; competitive pricing, setting a price similar to rivals; and penetration pricing, setting a low initial price to enter a market quickly. Price must reflect value and cover costs.
定价策略包括成本加成定价，在生产成本上加成；竞争性定价，将价格设定为与竞争对手相似；渗透定价，设定低初始价格以快速进入市场。价格必须反映价值并覆盖成本。
Place refers to how a product reaches the customer. This could be through physical shops, online stores, wholesalers or direct delivery. Promotion includes advertising, sales promotions, public relations and social media marketing to inform and persuade customers.
渠道指产品如何到达客户手中。这可以是通过实体店、网店、批发商或直接交付。促销包括广告、销售促进、公共关系和社交媒体营销，以告知和说服客户。
7. Operations Management | 运营管理
Operations management involves organising the production of goods and services efficiently. Businesses choose a production method based on the nature of the product and demand. Job production creates a unique product one at a time, like a tailor-made suit.
运营管理涉及高效组织商品和服务的生产。企业根据产品性质和需求选择生产方法。单件生产一次制作一件独特产品，如定制西装。
Batch production makes groups of identical products together. A bakery might bake loaves of bread in batches. Flow production, also called mass production, involves a continuous process on an assembly line, such as manufacturing soft drinks.
批量生产成批制作相同产品。面包店可能批量烤制面包。流水生产，也称大规模生产，是在装配线上连续进行的过程，例如生产软饮料。
Businesses aim to improve productivity, which measures output per worker per hour. Higher productivity reduces costs and increases competitiveness. Quality control checks products after production, while quality assurance builds quality into every stage of the process.
企业旨在提高生产力，即每小时每个工人的产出。更高的生产力降低成本并提高竞争力。质量控制是在生产后检查产品，而质量保证将质量融入过程的每个阶段。
Managing inventory (stock) is also critical. Holding too much stock costs money for storage and risks wastage. Holding too little can lead to stock-outs and lost sales. Just-in-time (JIT) systems aim to have stock delivered exactly when needed.
库存管理也至关重要。持有过多库存会增加仓储成本并有浪费风险。持有过少可能导致缺货和销售损失。准时制系统旨在让库存恰好需要时交付。
8. People in Business | 人力资源
People are a vital resource for any business. Human resource management (HRM) involves recruiting, training and motivating employees. The recruitment process starts with identifying a vacancy, then writing a job description and person specification.
人员是任何企业的重要资源。人力资源管理涉及招聘、培训和激励员工。招聘流程从确定空缺开始，然后撰写岗位描述和人员规格。
Businesses can recruit internally (from existing staff) or externally. Methods include advertising online, using recruitment agencies or personal recommendations. Selection may involve interviews, tests and assessment centres.
企业可以从内部（现有员工）或外部招聘。方法包括在线广告、使用招聘机构或个人推荐。选拔可能包括面试、测试和评估中心。
Training helps employees develop skills. Induction training introduces new hires to the business. On-the-job training happens while working, whereas off-the-job training takes place away from the workplace. Well-trained staff are more productive and make fewer errors.
培训有助于员工发展技能。入职培训向新员工介绍企业情况。在职培训在工作中进行，而非在职培训在工作场所外进行。训练有素的员工生产力更高，犯错更少。
Motivation affects how hard employees work. Financial motivators include wages, salaries, bonuses and profit sharing. Non-financial motivators include praise, promotion opportunities, job rotation and a positive work environment. Theories by Maslow and Herzberg explain different needs.
激励影响员工的工作积极性。财务激励包括工资、薪金、奖金和分红。非财务激励包括表扬、晋升机会、岗位轮换和积极的工作环境。马斯洛和赫茨伯格的理论解释了不同需求。
9. Financial Information | 财务信息
Businesses need to keep accurate financial records to monitor performance and make decisions. The income statement shows profit or loss over a period. Key figures include revenue (sales), cost of sales, gross profit, expenses and net profit.
企业需要保持准确的财务记录以监控绩效和做出决策。利润表显示一段时间内的利润或亏损。关键数据包括收入（销售额）、销售成本、毛利润、费用和净利润。
Gross profit = Revenue − Cost of sales. Net profit = Gross profit − Expenses. Profit is essential for rewarding owners, reinvesting and surviving downturns. A business with high revenue but uncontrolled costs can still fail.
毛利润 = 收入 – 销售成本。净利润 = 毛利润 – 费用。利润对回报所有者、再投资和度过衰退期至关重要。高收入但成本失控的企业仍可能失败。
The statement of financial position (balance sheet) shows what a business owns (assets) and owes (liabilities) at a specific date. Equity represents the owners’ stake. Assets commonly include cash, inventory, equipment and buildings.
财务状况表（资产负债表）显示企业在特定日期拥有的资产和欠下的负债。所有者权益代表所有者投入。资产通常包括现金、存货、设备和建筑物。
Cash flow is the movement of money into and out of a business. A cash flow forecast predicts future cash balances. A profitable business can still run out of cash if customers delay payment. Managing working capital is vital for liquidity.
现金流是资金进出企业的流动。现金流预测预估未来的现金余额。盈利的企业如果客户延迟付款仍然可能现金耗尽。管理营运资金对流动性至关重要。
10. External Influences on Business | 外部商业影响
Businesses operate in a changing environment. External factors can create opportunities and threats. The business cycle affects demand: during economic growth, spending rises, but in a recession, consumers cut back, forcing businesses to lower prices or innovate.
企业在不断变化的环境中运营。外部因素会带来机会和威胁。经济周期影响需求：经济增长期消费增加，但在衰退期消费者削减开支，迫使企业降低价格或创新。
Legal controls include employment laws, health and safety regulations, and consumer protection. For example, minimum wage laws set the lowest hourly pay rate. Businesses must comply or face fines and reputational damage.
法律控制包括就业法、健康与安全法规以及消费者保护。例如，最低工资法规定了最低小时工资标准。企业必须遵守，否则面临罚款和声誉损害。
Technology changes rapidly. E-commerce has allowed small businesses to reach global markets. Automation in factories improves productivity but may reduce the need for workers. Social media enables low-cost promotion and instant customer feedback.
技术变化迅速。电子商务使小企业能够触及全球市场。工厂自动化提高了生产力，但可能减少对工人的需求。社交媒体使低成本推广和即时客户反馈成为可能。
Competition forces businesses to improve quality, lower prices and offer better service. Environmental pressures are increasing too. Customers and governments expect businesses to reduce waste, pollution and carbon emissions. Sustainable practices can become a competitive advantage.
竞争迫使企业提高质量、降低价格并提供更好的服务。环境压力也在增加。客户和政府期望企业减少浪费、污染和碳排放。可持续发展实践可成为竞争优势。
