Knowing the format, marking criteria, and time constraints will shape how you allocate your revision energy.

一开始就要研究清楚面向 KS3 学生的国际经济竞赛的具体结构。有些侧重选择题知识测试，有些则要求长论文、政策辩论或投资模拟。了解竞赛形式、评分标准和时间限制，有助于你合理分配备考精力。

• Check official websites for sample tasks and past winning entries.
• 查阅官方网站的样题和往届获奖作品。
• Identify whether the competition is individual or team-based.
• 确认比赛是个人赛还是团队赛。

2. Building a Strong Economic Foundation | 建立扎实的经济学基础

International competitions often push beyond the standard KS3 syllabus. Make sure you are fully comfortable with fundamental ideas like scarcity, opportunity cost, and the basic economic problem before tackling advanced topics. A solid foundation allows you to apply concepts more creatively under pressure.

国际竞赛往往会超出标准 KS3 教学大纲的范围。在挑战高阶主题之前，务必先彻底掌握稀缺性、机会成本和基本经济问题等核心观念。扎实的基础能让你在压力下更灵活地运用概念。

Key Concept	Simple Explanation
Scarcity	Limited resources vs. unlimited wants
Opportunity Cost	The next best alternative forgone
Supply & Demand	Determines equilibrium price and quantity

你可以利用 IGCSE 经济学教材中的定义和图表来巩固理解，多画供需图，并尝试用现实例子解释每个概念。

3. Mastering Key Economic Concepts | 掌握关键经济概念

Beyond the basics, competitions frequently test elasticity, market structures, externalities, and macroeconomic indicators. Create quick-reference flashcards for PED, PES, YED, XED, and the differences between perfect competition, monopoly, and oligopoly. Use simple numerical examples to remember formulas without needing a calculator.

在基础之上，竞赛常考弹性、市场结构、外部性和宏观经济指标。为需求价格弹性、供给价格弹性、收入弹性、交叉弹性以及完全竞争、垄断和寡头垄断的区别制作速记卡片。用简单的数字例子来记忆公式，无需依赖计算器。

PED = %ΔQd ÷ %ΔP

弹性计算是许多竞赛的选择题热点，记得用中点公式避免符号混淆。

4. Developing Analytical and Critical Thinking | 培养分析和批判性思维

Judges look for the ability to evaluate rather than just describe. When you explain a policy, always consider both advantages and disadvantages. Practice writing ‘however’ paragraphs that discuss unintended consequences, equity issues, or time lags. Asking ‘why’ five times can help you uncover the deeper economic reasoning behind news stories.

评委看重的是评估能力，而非单纯的描述。在解释一项政策时，始终要考虑其利弊两面。练习写出以“然而”转折的段落，探讨意外后果、公平问题或时间滞后。追问五次“为什么”能帮你挖掘新闻事件背后的深层经济逻辑。

For example, when reading about a sugar tax, go beyond ‘it reduces consumption’ and consider its impact on low-income households, cross-border shopping, and producer responses.

例如，读到糖税时，不要停留在“减少消费”，还要思考它对低收入家庭、跨境购物以及生产者反应的影响。

5. Enhancing Essay Writing Skills | 提升论文写作技巧

Many top-tier competitions, such as the RES Young Economist of the Year, require a well-structured essay. Start with a clear introduction that defines key terms and sets out your argument. Use the PEEL method (Point, Evidence, Explanation, Link) for body paragraphs. Conclude with a balanced judgment that directly answers the question.

许多顶级竞赛，如英国皇家经济学会年度青年经济学家论文赛，都要求提交结构严谨的文章。开头要清晰定义关键术语并提出论点。主体段落采用 PEEL 法（观点、证据、解释、关联）。结尾给出平衡性的判断，直接呼应问题。

• Avoid vague language; use precise economic terminology.
• 避免含糊用语，使用精确的经济学术语。
• Include real-world examples to substantiate your arguments.
• 用现实案例支撑论点。
• Proofread for grammar and logical flow.
• 检查语法和逻辑通顺。

6. Staying Updated with Current Affairs | 关注时事

Economics competitions are rarely abstract; they demand real-world context. Set aside 15 minutes daily to read sections like the Business, Economy, or Finance pages of reputable news platforms. Keep a journal where you link a headline to an economic concept every day, for example connecting rising energy prices to cost-push inflation.

经济竞赛很少脱离实际，它们要求真实的语境。每天留出 15 分钟阅读权威新闻平台的商业、经济或财经板块。准备一个日志，每天将一条新闻标题与一个经济概念联系起来，比如把能源价格上涨与成本推动型通胀挂钩。

This habit not only enriches your essay examples but also prepares you for unseen case study questions that often appear in competition rounds.

这个习惯不仅能丰富你的论文素材，还能帮助你应对竞赛环节中常见的陌生案例题。

7. Practicing with Past Papers and Mock Tests | 真题与模拟测试

Hunt down any available past papers, sample questions, or even quiz questions from similar competitions. Simulate timed conditions to build speed and accuracy. After each attempt, spend twice the practice time analyzing mistakes. Look for patterns: are you consistently weak on macroeconomics or struggling with graph interpretation?

尽量搜集一切可用的真题、样题，乃至相似竞赛的问答。模拟限时环境提升速度与准确度。每次练习后，花两倍的时间分析错误。找规律：你是否在宏观经济学上持续较弱，还是在图表解读上吃力？

If official resources are scarce, create your own quizzes with a study partner, or use platforms like Quizlet to share sets on key terms and formulas.

如果官方资源稀缺，可以和学伴一起自编测验，或使用 Quizlet 等平台共享关键术语和公式的复习集。

8. Effective Team Collaboration | 高效团队合作

For team-based competitions, synergy is everything. Assign roles based on strengths: one member could focus on research and data, another on presentation design, and a third on oral delivery. Schedule regular check-ins where each person teaches a topic to the group — teaching is the best test of understanding.

对于团队类竞赛，协同配合至关重要。根据优势分配角色：一名组员专注研究和数据，另一名负责展示设计，第三名主管口头陈述。安排定期汇报，每人向团队讲解一个主题——教是最好的学。

Conflict may arise over differing economic viewpoints. Treat these as opportunities to deepen your analysis by acknowledging multiple perspectives and integrating them into a more nuanced argument.

不同的经济观点可能引发争论。把这些时刻当作深化分析的机会，承认多元视角并将其融入更细致的论证中。

---

9. Time Management and Exam Strategy | 时间管理与考试策略

In a timed competition, allocate your minutes wisely. If the paper has 5 questions and 60 minutes, assign roughly 12 minutes per question and stick to it. For essays, spend the first 3–4 minutes planning. Many students lose points because they rush into writing without a clear roadmap and then run out of time for the conclusion.

在限时竞赛中，要合理分配时间。如果试卷有 5 道题，限时 60 分钟，大约每题分配 12 分钟并严格遵循。写论文时，先用 3–4 分钟构思。许多同学因急于动笔而没有清晰的路线图，最后来不及写结论而丢分。

Use a simple wristwatch or the clock in the room; don’t rely on devices. Practising under timed conditions at home will make this feel natural on competition day.

使用简单的手表或考场时钟，不要依赖电子设备。在家限时练习能让比赛当天更从容。

10. Utilizing Online Resources and Communities | 利用在线资源与社群

The internet offers a wealth of free learning materials: video channels that illustrate economic models, forums where contestants share tips, and digital libraries with beginner-friendly papers. Join economics clubs on social media or Discord servers where you can debate policy questions and receive feedback on your arguments.

互联网上有大量免费学习资料：讲解经济模型的视频频道、参赛者分享技巧的论坛，以及适合初学者的数字论文库。加入社交媒体或 Discord 上的经济学社团，在那里你可以辩论政策问题并获得对论点的反馈。

Be selective. Stick to resources recommended by your teachers or official competition bodies to avoid outdated or misleading content.

要有选择性地使用资源。坚持采用老师或官方竞赛机构推荐的渠道，避免过时或误导性的内容。

---

11. Seeking Guidance from Mentors and Teachers | 寻求导师指导

An experienced teacher or a mentor who has previously participated in economics competitions can accelerate your growth immensely. They can pinpoint blind spots in your reasoning, suggest advanced reading, and help you interpret examiners’ comments. Don’t hesitate to ask for a short weekly meeting to discuss your progress.

一位经验丰富的老师，或者曾参加过经济竞赛的导师，能极大地加速你的成长。他们可以指出你逻辑中的盲区，推荐进阶读物，并帮你解读评委评语。不要犹豫，主动请求每周一次简短的会议来讨论进展。

If your school offers an Economics Society, attend consistently and volunteer to lead a session. Teaching younger students is a powerful way to solidify your own knowledge.

如果学校有经济学社，坚持参加并主动带领一次活动。教低年级学生是巩固自身知识的有效方法。

12. Maintaining a Healthy Balance and Mindset | 保持健康平衡与心态

Intensive preparation can lead to burnout if you neglect rest, exercise, and hobbies. Your brain consolidates information during sleep and downtime, so schedule regular breaks and ‘no-economics’ hours. Treat setbacks — like a low score on a practice paper — as data, not as personal failure, and adjust your study plan accordingly.

密集备战若忽视休息、锻炼和爱好，极易导致倦怠。大脑在睡眠和休息时整合信息，所以要定期安排休息时段和“无经济学”时间。把挫折——如模拟考低分——当作数据而非个人失败，相应地调整学习计划。

Approach competition day with curiosity and a love for the subject. The skills you build — critical thinking, communication, and resilience — will serve you far beyond any trophy.

带着好奇和对学科的热爱迎接比赛日。你所培养的技能——批判性思维、沟通力和韧性——将超越任何奖杯，终身受用。
