This article provides a step-by-step guide to mastering case study analysis, complete with a worked example.
案例研究是将经济理论付诸实践的强大方式。在KS3 WJEC经济中，你会遇到需要运用稀缺性、需求、供给和机会成本等概念的情境。本文提供了一份逐步掌握案例分析方法的指南，并附有完整示例。
1. What is an Economics Case Study? | 什么是经济案例分析？
An economics case study is a detailed description of a real or realistic situation that involves making choices with limited resources. It often presents a business, a consumer, or a government facing a problem. Your job is to use economic reasoning to explain what is happening and suggest possible solutions.
经济案例分析是对涉及经济决策、问题或概念的真实情境或情景的详细研究。它通常会呈现一个企业、消费者或政府面临的问题。你的任务是用经济推理来解释发生的情况并提出可能的解决方案。
These case studies may include data such as prices, costs, quantities sold, or survey results. You need to pull out the key economic concepts hidden in the story.
这些案例研究可能包含价格、成本、销量或调查结果等数据。你需要提取故事中隐藏的关键经济概念。
2. Why Are Case Studies Important? | 为什么案例分析很重要？
Case studies bridge the gap between textbook theory and the real world. They show you that economics is not just about graphs and definitions – it is about everyday decisions. By practising case studies, you develop critical thinking and problem-solving skills that are essential for exams and beyond.
案例研究弥合了课本理论与现实世界之间的鸿沟。它告诉你经济学不仅仅是图表和定义，而是关乎日常决策。通过练习案例分析，你可以培养批判性思维和解决问题的能力，这对考试和未来都很重要。

3. Step 1: Read Carefully and Identify the Economic Problem | 第一步：仔细阅读并识别经济问题
Begin by reading the case study twice. The first time, get a general understanding. The second time, underline or highlight any words that suggest an economic concept. Ask yourself: What is the main problem? Is it about scarcity? Is it a choice between alternatives? Is it about demand falling?
开始时阅读案例两遍。第一遍获取大致理解。第二遍勾画或高亮任何暗示经济概念的词语。问自己：主要问题是什么？是关于稀缺性吗？是在两种选择之间做抉择吗？是需求下降吗？
For KS3, typical problems revolve around limited budgets, businesses trying to increase profit, or consumers deciding how to spend money. Always look for 'limited' or 'choice' clues.
在KS3阶段，典型的问题围绕有限的预算、试图增加利润的企业或决定如何花钱的消费者展开。始终寻找 '有限' 或 '选择' 的线索。
4. Step 2: Extract Relevant Data and Economic Concepts | 第二步：提取相关数据与经济概念
Once you identify the main problem, list the key data provided. This might be numbers like costs, revenues, number of customers, or percentages. Also, note the economic concepts at play. Common KS3 concepts include:
一旦确定了主要问题，列出提供的关键数据。这些数据可能是成本、收入、顾客数量或百分比等数字。同时，注意正在发挥作用的经济概念。常见的KS3概念包括：
- Scarcity – not enough resources to satisfy all wants. | 稀缺性 – 资源不足以满足所有欲望。
- Opportunity cost – the next best alternative given up when a choice is made. | 机会成本 – 做出选择时所放弃的次优选择。
- Demand and supply – how much consumers are willing/able to buy and how much producers offer. | 需求与供给 – 消费者愿意且能够购买的数量以及生产者提供的数量。
- Price – determined by the interaction of demand and supply. | 价格 – 由需求和供给的相互作用决定。
- Costs, revenue, profit – basic business calculations. | 成本、收入、利润 – 基本的商业计算。
