1. Define Marketing and Explain Its Role in a Business | 定义市场营销并解释其在企业中的作用
Marketing is the management process responsible for identifying, anticipating and satisfying customer needs profitably. The three verbs matter: 'identifying' means finding out what customers want now, 'anticipating' means predicting what they will want next, and 'profitably' means doing both without destroying the firm's margins.
市场营销是负责识别、预测并盈利地满足客户需求的管理过程。三个动词都很关键："识别"指了解顾客当下的需求，"预测"指判断他们下一步想要什么，"盈利地"指在满足需求的同时不损害企业的利润空间。
It is not just advertising or selling. Marketing also includes market research, product design, pricing, distribution and after-sales service. A firm that only advertises without researching its customers is really just guessing loudly.
它绝不只是广告或销售。市场营销还包括市场调研、产品设计、定价、分销和售后服务。只做广告而不研究顾客的企业，本质上只是在"大声猜测"。
Its role is to create value for customers and build lasting relationships, which in turn helps the business achieve objectives such as revenue growth, market share and customer loyalty. Without effective marketing, even a technically excellent product may fail because customers do not know it exists, cannot see why it is better than a rival's, or cannot buy it conveniently.
市场营销的作用是为顾客创造价值并建立持久关系，进而帮助企业实现收入增长、市场份额与顾客忠诚等目标。若缺乏有效的市场营销，即使技术再优秀的产品也可能失败，因为顾客不知道它存在、看不出它比对手好在哪里，或者买起来不方便。
Marking note: a full-mark definition needs 'needs and wants', 'profitably' and the idea of exchange; the explanation must move beyond advertising to at least two other marketing activities and link marketing to a business objective.
得分提示：满分定义需包含"需求与欲望""盈利地"以及"交换"的概念；解释部分必须超越广告，至少再提两项营销活动，并把营销与某个企业目标挂钩。
2. Marketing Objectives and Their Link to Corporate Objectives | 营销目标及其与公司目标的联系
Marketing objectives are the specific, measurable targets set for the marketing function, such as increasing market share from 12% to 18% within two years, launching three new products per year, or raising brand awareness among 18-24 year olds to 60%.
营销目标是营销职能设定的具体、可衡量的目标，例如两年内把市场份额从 12% 提高到 18%、每年推出三款新产品，或把 18-24 岁人群的品牌认知度提升到 60%。
They must be consistent with corporate objectives. If the corporate aim is to maximise profit, a marketing objective of aggressive sales growth through heavy discounting may conflict with it. If the corporate aim is to enter a new export market, marketing objectives should cover channel selection, local pricing and promotional adaptation.
它们必须与公司目标保持一致。若公司目标是利润最大化，那么"通过大幅折扣激进冲销量"的营销目标就与之冲突；若公司目标是进入新的出口市场，营销目标就应涵盖渠道选择、本地化定价与促销调整。
Useful evaluation point: marketing objectives are not just a consequence of corporate strategy, they also feed back into it. A realistic market-share target can reshape the whole corporate plan.
有用的评估要点：营销目标不只是公司战略的结果，它也会反向影响公司战略。一个现实可行的市场份额目标，可能重塑整个公司计划。
3. Market Segmentation, Targeting and Positioning | 市场细分、目标市场选择与定位
Market segmentation is dividing a market into groups of consumers with similar characteristics or needs. Common bases are demographic (age, gender, income), geographic (region, climate), psychographic (lifestyle, values) and behavioural (usage rate, loyalty, benefits sought).
市场细分是把一个市场划分为具有相似特征或需求的消费者群组。常用的细分依据包括人口统计（年龄、性别、收入）、地理（地区、气候）、心理（生活方式、价值观）和行为（使用频率、忠诚度、所追求的利益）。
Targeting is choosing which segment(s) to serve: undifferentiated (whole market), differentiated (several segments with different offers), concentrated/niche (one small segment), or micro-marketing (individual customers).
目标市场选择是决定服务哪些细分市场，方式包括无差异营销（面向整个市场）、差异化营销（多个细分市场配不同产品）、集中/利基营销（只做一个细分市场）以及微营销（针对个体顾客）。
Positioning is the place a brand occupies in the customer's mind relative to competitors, usually summarised in a positioning map with two axes such as price and quality. Good answers identify a gap on the map and explain why it is profitable, not merely empty.
定位是品牌在顾客心中相对于竞争者的位置，通常用价格与质量等两轴定位图来表达。优秀答案会指出定位图上的空白位置，并解释它为何有利可图，而不只是"没人做"。
Benefits of segmentation: better matching of product to customer, more efficient use of the promotional budget, higher prices justified by a tailored offer, and stronger brand loyalty. Drawbacks: narrower market, higher research and production costs, and the risk that a segment is too small to be profitable.
细分的好处：产品与顾客匹配更佳、促销预算使用更高效、因产品贴合需求而可支撑更高价格、品牌忠诚度更强。缺点：市场变窄、调研与生产成本上升，以及细分市场过小而无利可图的风险。
4. Market Research: Primary versus Secondary Data | 市场调研：一手数据与二手数据
Market research is the systematic collection, recording and analysis of data about customers, competitors and the market. It reduces the risk of costly mistakes, but it is never a guarantee, because consumer tastes shift and forecasts can be wrong.
市场调研是对顾客、竞争者及市场数据进行系统收集、记录与分析的过程。它降低了代价高昂的决策失误风险，但从不构成保证，因为消费者偏好会变化、预测也会出错。
Primary research is collected first-hand for the specific problem: surveys, interviews, focus groups, observation and test marketing. It is up to date and tailored, but expensive, time-consuming, and prone to sampling bias if the sample is small or unrepresentative.
一手调研是针对特定问题首次收集的数据：问卷调查、访谈、焦点小组、观察法和试销。它时效性强且贴合需求，但成本高、耗时长，且样本过小或缺乏代表性时容易出现抽样偏差。
Secondary research uses data that already exists: government statistics, trade association reports, competitor accounts, company records and published academic studies. It is quicker and cheaper, often covering long time periods, but may be outdated, defined differently from your question, or collected for another purpose.
二手调研使用已有数据：政府统计、行业协会报告、竞争者财报、公司内部记录与已发表的学术研究。它更快、更便宜，且常覆盖较长时间段，但可能过时、口径与你的问题不一致，或者原本是为其他目的收集的。
| Criteria 标准 | Primary 一手 | Secondary 二手 |
| Cost 成本 | High 高 | Low 低 |
| Relevance 相关性 | Tailored 量身定制 | May not fit 可能不匹配 |
| Currency 时效 | Up to date 最新 | Can be dated 可能过时 |
5. The Marketing Mix: 4Ps and 7Ps | 营销组合：4P 与 7P
The marketing mix is the set of controllable variables a firm combines to satisfy its target market. The classic 4Ps are Product, Price, Place and Promotion; for services the extended 7Ps add People, Process and Physical evidence.
营销组合是企业为满足目标市场而组合起来的一整套可控变量。经典的 4P 是产品（Product）、价格（Price）、渠道（Place）和促销（Promotion）；针对服务业，扩展的 7P 增加了人员（People）、流程（Process）和有形展示（Physical evidence）。
Each element must reinforce the others. A luxury positioning with a discount price, a supermarket channel and a mass-market TV campaign is internally inconsistent and confuses customers.
每个要素都必须相互强化。若定位为奢侈品，却采用折扣价格、超市渠道与大众化电视广告，就是内部不一致的组合，只会让顾客困惑。
Product covers design, quality, features, branding, packaging and after-sales service. Price must reflect costs, competitors and perceived value. Place covers distribution channels, retailers and logistics. Promotion includes advertising, sales promotion, personal selling, public relations and direct marketing.
产品涵盖设计、质量、功能、品牌、包装与售后服务。价格必须反映成本、竞争者与顾客感知价值。渠道涵盖分销渠道、零售商与物流。促销则包括广告、销售促进、人员推销、公共关系与直复营销。
6. Product Decisions: Product Life Cycle and the Boston Matrix | 产品决策：产品生命周期与波士顿矩阵
The product life cycle shows sales and profit over time through development, introduction, growth, maturity and decline. Cash flow is typically negative at introduction, peaks around growth/maturity and falls in decline, so the mix must change at each stage.
产品生命周期把销售额与利润随时间的变化分为开发、导入、成长、成熟与衰退五个阶段。现金流通常在导入期为负，在成长/成熟期达到高峰，在衰退期下滑，因此营销组合在每个阶段都必须调整。
Introduction: heavy promotion, price skimming or penetration. Growth: build brand loyalty, expand distribution, consider price cuts. Maturity: differentiate, extend the product line, use sales promotions. Decline: harvest, divest, or reposition.
导入期：促销投入大，可采用撇脂定价或渗透定价。成长期：建立品牌忠诚、拓展分销、考虑降价。成熟期：差异化、延伸产品线、运用销售促进。衰退期：收割、剥离或重新定位。
The Boston Matrix classifies products by market growth and relative market share: stars (high growth, high share) need investment to become cash cows; cash cows (low growth, high share) fund the rest; question marks (high growth, low share) need a build-or-divest decision; dogs (low growth, low share) are usually candidates for withdrawal.
波士顿矩阵按市场增长率与相对市场份额对产品分类：明星（高增长、高份额）需继续投资以成为金牛；金牛（低增长、高份额）为其他业务提供资金；问题（高增长、低份额）要在"加投"与"剥离"间抉择；瘦狗（低增长、低份额）通常是退出候选。
Evaluation point: the matrix is a snapshot based on relative market share, which can mislead in markets where a small share of a fast-growing niche is highly profitable.
评估要点：该矩阵是基于相对市场份额的静态快照，在市场高速增长且"小份额、高利润"的利基市场中可能产生误导。
7. Pricing Strategies and Price Elasticity of Demand | 定价策略与需求价格弹性
Common pricing strategies: cost-plus (mark-up on unit cost), penetration (low initial price to build share), price skimming (high initial price to recover R&D), competitive pricing, predatory pricing (illegal if it drives out competition to raise prices later), price discrimination, and psychological pricing.
常见定价策略包括：成本加成定价（在单位成本上加成）、渗透定价（低价快速建立份额）、撇脂定价（高价回收研发投入）、竞争导向定价、掠夺性定价（若以排挤竞争后涨价为目的则属违法）、差别定价与心理定价。
Price elasticity of demand (PED) measures responsiveness of quantity demanded to a price change:
需求价格弹性（PED）衡量需求量对价格变动的敏感程度：
PED = %Δ Quantity Demanded ÷ %Δ Price
If PED = −2.0, demand is elastic: a 10% price rise cuts quantity demanded by about 20%, so total revenue falls. If PED = −0.4, demand is inelastic: a 10% price rise cuts quantity demanded by only 4%, so total revenue rises.
若 PED = −2.0，需求富有弹性：价格上涨 10% 会使需求量下降约 20%，总收入随之减少。若 PED = −0.4，需求缺乏弹性：价格上涨 10% 仅使需求量下降 4%，总收入因此上升。
Firms should therefore raise price when demand is inelastic and be cautious when it is elastic. Elasticity is higher where there are close substitutes, the product is a large share of income, or the purchase is discretionary rather than habitual.
因此企业在需求缺乏弹性时应提价，在需求富有弹性时则应谨慎。当存在相近替代品、产品支出占收入比重较大，或属于可选消费而非习惯性购买时，弹性通常更高。
8. Promotion and Place: Communication and Distribution | 促销与渠道：沟通与分销
Promotion aims to inform, persuade and remind. The promotional mix depends on the product (industrial goods rely on personal selling, fast-moving consumer goods on advertising), the budget, the target audience, the stage in the life cycle and legal constraints on advertising.
促销的目标是告知、说服与提醒。促销组合取决于产品类型（工业品依赖人员推销，快速消费品依赖广告）、预算、目标受众、产品生命周期阶段以及广告方面的法律限制。
Above-the-line promotion uses paid media that reach a mass audience, such as television, press and online display; below-the-line promotion targets specific customers through sales promotions, direct mail, sponsorship, PR and trade shows.
线上（above-the-line）促销使用触达大众的付费媒体，如电视、报刊与网络展示广告；线下（below-the-line）促销则通过销售促进、直邮、赞助、公关与展会对特定顾客进行定向推广。
Place decisions cover the channel of distribution — manufacturer to retailer to consumer, or direct through own shops and e-commerce. A short channel gives more control and higher margin per unit; a long channel gives wider reach but less control over pricing and presentation, and raises the risk of channel conflict.
渠道决策涉及分销渠道的选择——制造商到零售商再到消费者，或通过自营门店与电商直销。短渠道控制力更强、单位毛利更高；长渠道覆盖面更广，但对价格与陈列的控制更弱，且更容易产生渠道冲突。
9. Worked Calculations: Market Size, Share, Growth and Contribution | 计算题精解：市场规模、份额、增长与贡献
Worksheet calculation questions are marked on method, so always write the formula before substituting figures.
练习题中的计算题按方法给分，因此务必先写出公式，再代入数据。
Market Share (%) = (Business Sales ÷ Total Market Sales) × 100
Market Growth (%) = ((Current Sales − Previous Sales) ÷ Previous Sales) × 100
Contribution per Unit = Selling Price − Variable Cost per Unit
Worked example: a firm sells 40,000 units at $25 in a market worth $2,000,000. Sales revenue = 40,000 × $25 = $1,000,000, so market share = ($1,000,000 ÷ $2,000,000) × 100 = 50%.
示例：某企业以 25 美元售出 40,000 件，所在市场总值 2,000,000 美元。销售收入 = 40,000 × 25 = 1,000,000 美元，因此市场份额 = (1,000,000 ÷ 2,000,000) × 100 = 50%。
If the market was worth $1,600,000 last year, market growth = ((2,000,000 − 1,600,000) ÷ 1,600,000) × 100 = 25%. With variable cost of $15 per unit, contribution per unit = $25 − $15 = $10, and total contribution = 40,000 × $10 = $400,000, which must cover fixed costs before any profit is earned.
若该市场去年总值为 1,600,000 美元，则市场增长率 = ((2,000,000 − 1,600,000) ÷ 1,600,000) × 100 = 25%。若单位可变成本为 15 美元，则单位贡献 = 25 − 15 = 10 美元，总贡献 = 40,000 × 10 = 400,000 美元，须先覆盖固定成本后才产生利润。
Interpretation matters: a 25% market growth is only favourable if the firm's own sales grew at least as fast, otherwise its share has fallen even though revenue rose.
解读同样重要：25% 的市场增长只有在企业自身销售增速不低于该水平时才是有利的，否则即使收入上升，其市场份额其实已经下滑。
10. Case-Study Analysis: Building Chains of Reasoning | 案例分析：构建论证链
Analysis marks come from chains of reasoning, not from lists. Each chain should link a marketing decision to a customer response and then to a financial or strategic outcome.
分析分来自论证链，而非罗列要点。每一条链条都应把某项营销决策连接到顾客反应，再连接到财务或战略结果。
Weak answer: 'Lowering the price will increase sales.' Strong answer: 'Cutting the price from $20 to $17 reduces the unit contribution from $8 to $5, so the firm must sell 60% more units to earn the same total contribution; this is achievable only if demand is elastic enough and competitors do not match the cut.'
薄弱答案："降价会增加销量。"优秀答案："把价格从 20 美元降到 17 美元，单位贡献由 8 美元降到 5 美元，因此企业必须多卖 60% 才能获得相同的总贡献；只有当需求足够富有弹性、且竞争者不跟进降价时，这一目标才可能实现。"
Always anchor the chain in the case evidence: quote the market share figure, the competitor's price, the target segment or the budget constraint. Generic theory without case context normally stays in Level 1 or 2.
务必把论证链锚定在案例证据上：引用市场份额数据、竞争者价格、目标细分市场或预算约束。脱离案例情境的通用理论通常只能停留在 Level 1 或 Level 2。
11. Evaluation Skills: Judgement, Trade-offs and Prioritisation | 评估技巧：判断、权衡与优先次序
Evaluation is the top band of the mark scheme. It requires a judgement, not a summary. Phrases such as 'it depends on', 'the most important factor is', 'in the short run... but in the long run' signal evaluation to the examiner.
评估是评分标准的最高档，它要求给出判断，而不是复述。像"这取决于""最重要的因素是""短期内……但长期来看"这样的表述，能向评分者清晰传递评估意图。
Three reliable evaluation moves: (1) weigh the arguments and say which is stronger and why; (2) set out the conditions under which the recommendation holds; (3) prioritise, using criteria such as cost, speed, risk, reversibility or fit with corporate objectives.
三种可靠的评估手法：（1）权衡各方论点，说明哪一方更强及其原因；（2）指出建议成立所需的条件；（3）排出优先次序，可用成本、速度、风险、可逆性或与公司目标的契合度作为标准。
Worked judgement: 'On balance the firm should use penetration pricing in its new Asian market, because brand awareness is low and demand there is likely elastic; however, this is only sustainable if unit variable costs fall with higher volume, otherwise the strategy destroys contribution and the firm would be better advised to enter through a joint venture with a local distributor.'
评估范例："总体而言，该企业在新亚洲市场应采用渗透定价，因为当地品牌认知度低、需求很可能富有弹性；但这一做法只有在单位可变成本随销量上升而下降时才可持续，否则将侵蚀贡献，此时更明智的选择是通过与本地分销商成立合资企业进入市场。"
12. Common Mistakes and Mark Scheme Checklist | 常见错误与评分标准清单
The most frequent error is defining marketing as 'advertising'. A second is giving a list of promotional methods when the question asks about the marketing mix as a whole. A third is calculating market share without stating units or showing the formula.
最常见的错误是把市场营销定义为"广告"。其次，在题目问及整体营销组合时只罗列促销方式。第三，计算市场份额时不写单位或未展示公式。
Another common weakness is ignoring the constraint in the case, such as a limited promotional budget or a small firm with no distribution network. Top-band answers use the constraint as the basis for their judgement.
另一个常见薄弱点是无视案例中的约束条件，例如促销预算有限或企业规模小、没有分销网络。高档答案会把这种约束作为判断的依据。
Before you finish, run this checklist:
写完后请对照以下清单自查：
- Have I defined every technical term I used? | 我是否定义了所用到的每一个专业术语？
- Have I shown formulas and units in calculations? | 计算中是否写出了公式与单位？
- Has every point been applied to the case? | 每一个论点是否都结合了案例？
- Have I developed at least three chains of reasoning? | 是否至少展开了三条论证链？
- Have I reached a clear, justified judgement? | 是否给出了清晰且有依据的判断？
Time management tip: for a 20-mark marketing question, spend roughly 5 minutes planning, 20 minutes writing and 3 minutes checking calculations and the final judgement.
时间管理提示：对于 20 分的市场营销题，建议约 5 分钟构思、20 分钟作答、3 分钟检查计算与最终判断。
