要在 IB 经济论文中拿高分，仅仅掌握理论远远不够；你必须按照评分标准，采用清晰、有结构的写作方法。本指南为 Paper 1 的 10 分题和 15 分题提供了可直接套用的模板与技巧，帮助你构建有逻辑的论证、有效融入图表并提出有深度的评估。无论你目前的目标是 6 分还是 7 分，这些框架都能让你的写作更加犀利，信心更足。
1. Understanding the IB Economics Essay Landscape | 理解 IB 经济论文的考法
In IB Economics Paper 1, you face two essay questions, each split into part (a) for 10 marks and part (b) for 15 marks. Part (a) largely tests your ability to define, explain and apply economic theory, while part (b) focuses on discussion, analysis and evaluation. The two parts together demand a balance of precise knowledge and critical thinking, and a well-structured essay is essential to keep your answer focused under timed conditions.
在 IB 经济 Paper 1 中，你需要完成两道论述题，每题分为 (a) 小题（10 分）和 (b) 小题（15 分）。(a) 题主要考查定义、解释和运用经济理论的能力，而 (b) 题则重点考查讨论、分析和评估。两部分相结合，要求考生在精确知识和批判性思维之间取得平衡；在限时的考试环境下，结构清晰的论文对保持回答的针对性至关重要。
Examiners mark essays using specific criteria: knowledge and understanding, application and analysis, synthesis and evaluation, and appropriate terminology. Therefore every paragraph should contribute to these criteria. The templates we explore treat each mark band as a puzzle piece, so you never leave a criterion unaddressed.
考官根据具体的标准进行评分：知识理解、应用与分析、综合与评估，以及恰当使用术语。因此，每一段文字都应该为这些标准服务。我们接下来探讨的模板把每个得分点看作一块拼图，让你绝不会遗漏任何一项评分要求。
2. Decoding Command Terms | 解析指令词
Command terms set the boundaries for your response. For part (a), the most frequent instruction is ‘Explain’. This requires you to describe a theory, concept or policy in detail, showing how causes lead to effects. You must establish a chain of reasoning, not just state a definition. Other possible terms include ‘Describe’ or ‘Outline’, but ‘Explain’ dominates.
指令词划定了你作答的边界。(a) 题最常见的指令是 “解释” (Explain)，要求你详细描述一个理论、概念或政策，阐明因果关系的过程。你必须建立推理链条，而不是仅仅给出一个定义。其他可能会出现的词汇还有 “描述” (Describe) 或 “概述” (Outline)，但“解释”占主导地位。
For part (b), the principal command terms are ‘Discuss’ and ‘Evaluate’. ‘Discuss’ expects a balanced review of arguments for and against, often ending with a justified conclusion. ‘Evaluate’ goes further, demanding judgments based on criteria such as effectiveness, stakeholder impacts, short-term versus long-term consequences, and underlying assumptions. IB examiners reward candidates who can prioritise and weigh arguments, not just list pros and cons.
(b) 题的核心指令词是 “讨论” (Discuss) 和 “评估” (Evaluate)。“讨论” 要求你对支持和反对的论点进行平衡的审视，通常最终要给出一个有依据的结论。“评估” 则更进一步，要求你基于效果、利益相关方影响、短期与长期后果、隐含假设等标准做出判断。IB 考官钟爱那些能对各种论点进行优先排序和权衡的考生，而非仅仅罗列利弊。
Always underline the command term in the question. Treat it as a signpost: if you see ‘Explain’, set out a clear analytical cascade; if you see ‘Evaluate’, build a structured judgment framework. Misreading the command term is one of the fastest ways to lose marks.
务必在读题时把指令词下划线。把它当作路标：看到 “Explain” 就要展开清晰的分析链条；看到 “Evaluate” 就要搭建结构化的判断框架。误读指令词是快速丢分的常见原因之一。
3. The 10-Mark Part (a) Template | 10 分题 (a) 模板
The 10-mark question assesses your ability to explain a specific economic concept. A reliable template follows the DEED sequence: Define, Explanation, Example (optional but recommended) and Diagram. Start with a precise definition of the key terms, which immediately earns the knowledge mark. For instance, if the question concerns indirect taxes, define indirect tax and give a short example.
10 分题考查你解释某个经济概念的能力。一个可靠的模板是 DEED 序列：定义 (Define)、解释 (Explanation)、例子 (Example，推荐使用) 和图表 (Diagram)。首先要对关键词进行精确定义，这能立即帮你拿到知识分。例如，如果题目与间接税有关，就要定义间接税并给出一个简短的例子。
Move to the explanation: build a clear chain of reasoning that links the policy or concept to the outcomes. Explain step by step how a government imposes an ad valorem tax, how it shifts the supply curve leftwards, and how it raises price and reduces quantity. Use linking phrases such as ‘this leads to’, ‘consequently’ and ‘as a result’ to keep the logic flowing. Avoid unexplained jumps.
接着进入解释环节：构建一条清晰的推理链条，将政策或概念与结果联系起来。一步步说明政府如何征收从价税，如何导致供给曲线向左移动，又如何提高了价格、减少了数量。使用 “这导致”、“因此”、“结果是” 等连接短语，确保逻辑流畅。避免未经解释的逻辑跳跃。
Always integrate a well-drawn diagram. In part (a) the diagram does not need to be evaluated; it illustrates your explanation. Label axes, curves, equilibrium points and the shifts clearly. Many candidates lose marks because they draw a perfect diagram but never explicitly refer to it in the text. Always guide the reader: “As shown in Figure 1, the supply curve shifts from S1 to S2…”
始终要整合入一个描绘清晰的图表。在 (a) 题中，图表无需评估；它用来辅助说明你的解释。要清晰地标注坐标轴、曲线、均衡点以及移动。许多考生丢分是因为他们画了完美的图，却没有在正文中明确引用它。一定要引导读者：“如图 1 所示，供给曲线从 S1 移动到 S2……”
A short real-world example can strengthen the application. Mentioning a specific country or product – such as the sugar tax in the UK – adds contextual understanding without requiring extensive detail. Keep it concise so the explanation remains the focus.
一个简短的真实世界例子能增强应用层面的展示。提及具体的国家或产品——比如英国的糖税——可增加情境理解，但无需展开大量细节。保持简洁，让解释仍是重心所在。
4. The 15-Mark Part (b) Template | 15 分题 (b) 模板
The 15-mark question demands a well-balanced discussion and high-level evaluation. A productive template is DEEDE: Define (if key terms are not already defined in part a), Explanation, Evaluation using multiple perspectives, Decision or judgment, and Diagram (if relevant to the evaluation). This structure ensures you hit every assessment criterion.
15 分题要求均衡的讨论和高水平的评估。一个有效的模板是 DEEDE：定义 (Define，如果关键术语未在 (a) 部分定义)、解释 (Explanation)、多视角评估 (Evaluation)、判断或结论 (Decision) 以及图表 (Diagram，如果与评估相关)。这个结构确保你覆盖每一个评分标准。
Begin by briefly restating the key concept from part (a), but avoid copying large blocks of text. Quickly outline the theory or policy in question, then shift to evaluation. Evaluation should not be a random list; it must be a structured assessment. Use a framework such as CLASPP: Consequences, Limitations, Assumptions, Stakeholders, Priorities, and Perspectives over time.
开头先简短重述 (a) 部分的关键概念，但避免大段照抄文字。快速勾画题目中的理论或政策，然后转向评估。评估不应该是随意的罗列，而应是有结构的评价。可以使用 CLASPP 框架：后果 (Consequences)、局限性 (Limitations)、假设 (Assumptions)、利益相关方 (Stakeholders)、优先事项 (Priorities) 和时间视角 (Perspectives over time)。
Discuss the effectiveness of the policy by considering different stakeholders: consumers, producers, the government and society. For example, a minimum price for alcohol may reduce consumption for low-income groups but hurt small producers. Weigh the short-term benefits against long-term structural changes. Always justify your judgments with economic reasoning, not personal opinion.
通过分析不同利益相关方来讨论政策的效果：消费者、生产者、政府和社会。例如，酒精的最低限价或许能减少低收入群体的消费，却会损害小生产者的利益。权衡短期收益与长期结构性变化。始终用经济推理来支撑你的判断，而非个人观点。
Conclude decisively. A strong conclusion synthesises the evaluation and answers the question directly: which policy is more effective and under what conditions. Avoid sitting on the fence by simply stating ‘it depends’ without specifying on what it depends. Diagrams in part (b) can be used to show evaluation points, such as varying elasticities or the impact of subsidies, but only include them if they add analytical value.
要有明确的结论。有力的结论会综合评估内容并直接回答问题：哪种政策更有效，以及需要什么样的条件。避免只是说 “要视情况而定” 却不指明具体取决于什么。(b) 题中的图表可以用来展示评估要点，比如不同的弹性或补贴的影响，但仅在它们具有分析价值时才纳入。
5. Using Diagrams as Analytical Tools | 将图表用作分析工具
Diagrams earn marks for analysis, but only if they are accurate, fully labelled and connected to your argument. For each diagram, you need a title, labelled axes (Price, Quantity, etc.), identifiable curves (D, S, MPC, MSB), initial and new equilibrium points (E1, E2), and clear shifts or movements. Use arrows to indicate direction of change.
图表能为分析部分赚取分数，但前提是它们准确、完整标注、并且与你的论证相关联。每个图表都需要有标题、标注坐标轴（价格、数量等）、可辨识的曲线（D, S, MPC, MSB）、初始均衡点和新均衡点（E1, E2），以及清晰的移动或滑动。使用箭头标示变化方向。
Do not simply drop a diagram into your essay and assume the examiner will decode it. Introduce it before you draw it, explain what it shows after you draw it, and refer back to it in your reasoning. This triple engagement transforms a picture into an analytical asset. For part (b) questions, adapt diagrams to illustrate evaluation points – for example, draw a second diagram with a flatter demand curve to demonstrate varied elasticity effects.
不要简单地把图表扔进文章，然后指望考官自己去解码。画图之前要先介绍，画图之后要解释它展示了什么，并在推理过程中回扣图表。这种三重参与能把一幅图变成分析利器。对于 (b) 题，可调整图表来展示评估要点——例如，再画一幅需求曲线较平坦的图表，以说明不同的弹性效应。
A common mistake is to clutter diagrams with too many arrows or labels that confuse rather than clarify. Keep them clean and precise. If you use a diagram that appears in part (a) for part (b), draw it again with modifications if necessary. Never reference “the diagram above” between parts; each part is self-contained.
常见错误是把图表弄得乱七八糟，箭头和标注过多，反而让人困惑。保持图表的整洁与精确。如果你在 (b) 题中使用了 (a) 题出现过的图表，必要时应重新绘制并加以修改。千万不要在两部分之间使用“上图”这样的字眼；每一部分都应是独立的。
6. Building Evaluation Skills with CLASPP | 用 CLASPP 框架锻造评估能力
Evaluation is what separates good essays from outstanding ones. The CLASPP checklist gives you a mental map to generate sophisticated evaluative points. Consequences examine direct and indirect effects. Limitations question the theoretical assumptions behind a model. Assumptions probe whether ceteris paribus holds in reality. Stakeholders map out who gains and who loses. Priorities consider government objectives and trade-offs. Perspectives bring in short-term versus long-term and macroeconomic context.
评估是区分好文章与高分文章的关键。CLASPP 清单给你提供了一张思维导图，帮你生成有深度的评估论点。后果 (Consequences) 考察直接与间接效应。局限性 (Limitations) 质疑模型背后的理论假设。假设 (Assumptions) 探查“其他条件不变”在现实中是否成立。利益相关方 (Stakeholders) 辨析谁受益、谁受损。优先事项 (Priorities) 考量政府目标与取舍。视角 (Perspectives) 引入短期与长期对比以及宏观经济背景。
Apply CLASPP by selecting the most relevant three or four elements, not by mechanically ticking every box. For a question about market-based supply-side policies, you might focus on Limitations (time lags, political opposition), Stakeholders (high-income earners versus low-income households) and Perspectives (short-term pain for long-term gain). Then build a paragraph around each element and link them with cohesive transitions.
运用 CLASPP 时要选取最相关的三到四个要素，而不是机械地每个都涵盖。对于一道关于市场化供给侧政策的题目，你可以聚焦于局限性（时滞、政治阻力）、利益相关方（高收入群体与低收入家庭）以及视角（短期阵痛换取长期回报）。然后围绕每个要素撰写一段，并用连贯的过渡词将它们串联起来。
IB examiners specifically look for “evaluative synthesis” – the ability to pull together different strands into a coherent overall judgment. Practice writing concluding sentences that weigh conflicting evidence, such as “Although the policy X imposes immediate welfare losses on group A, the long-run productivity gains and the net social benefit justify its implementation.” This demonstrates high-level thinking.
IB 考官特别看重“评估性综合”——把不同的线索整合为一个连贯的总体判断。练习撰写能够权衡对立证据的结论句，例如“尽管政策 X 在短期内给群体 A 带来福利损失，但其长期的生产率提升和社会净收益证明其实施是合理的。”这能展现出高层次的思维能力。
7. Selecting and Embedding Real-World Examples | 选择并嵌入真实世界案例
Real-world examples ground your analysis and signal application skills. For IB Economics, you should build a library of current and historical examples across micro and macro topics. Good micro examples include sugar taxes (negative externalities), minimum wage laws (price floors) and carbon permits (cap and trade). Macro examples might cover expansionary fiscal policy during COVID-19 or contractionary monetary policy to tackle inflation.
真实世界案例能让你的分析落到实处，并显示出应用能力。在 IB 经济中，你应当建立涵盖微观与宏观话题的案例库，包含近期和历史案例。好的微观例子有糖税（负外部性）、最低工资法（价格下限）和碳排放许可证（总量控制与交易）。宏观例子则可包括新冠疫情期间的扩张性财政政策或对抗通胀的紧缩性货币政策。
Embed the example naturally into your paragraph; do not tack it on at the end as an afterthought. For instance, when explaining how an indirect tax reduces consumption, integrate the UK Soft Drinks Industry Levy by stating: “In the UK, the sugar tax led to a reformulation of drinks and a 28% reduction in sugar per 100ml, illustrating the leftward shift of the supply curve and decreased equilibrium quantity.”
要把例子自然地嵌入段落当中，而不是像事后补遗一样贴在末尾。例如，在解释间接税如何减少消费量时，可以这样融入英国软饮料行业税：“在英国，糖税促使饮料重新配方，并使每 100 毫升含糖量降低了 28%，这正说明了供给曲线左移以及均衡交易量的下降。”
Keep examples concise; one or two sentences are usually enough. The detail should serve the economic concept, not overwhelm it. Avoid generic statements like “Many countries use subsidies for agriculture.” Instead specify a country and a product: “The EU’s Common Agricultural Policy provides guaranteed prices to cereal farmers, leading to surpluses depicted by a price floor diagram.”
例子要保持简洁；通常一两个句子就足够了。细节应该为经济概念服务，而不是喧宾夺主。避免使用“许多国家对农业实施补贴”这类泛泛而谈的表述。要具体到国家和产品：“欧盟的共同农业政策向谷物农民提供保证价格，导致了在价格下限图中所示的过剩。”
8. Avoiding Common Essay Pitfalls | 避开常见的论文陷阱
One of the biggest mistakes is writing a purely descriptive part (b) when evaluation is required. Candidates who only explain the theory and then add a single sentence saying “this policy is effective” will score poorly. You must dedicate at least half of your part (b) word count to evaluation and justified judgment. Simply listing advantages and disadvantages without weighting them is another trap.
一个最大的错误是，当 (b) 题要求评估时，你却写了一篇纯描述性的回答。考生如果只是解释理论，然后加一句“这个政策是有效的”，分数将会很低。你至少要把 (b) 题一半的篇幅用于评估和有依据的判断。另一个陷阱是仅仅罗列优缺点而不进行权衡。
Diagrams with missing labels, confused shifts, or generic titles like “Graph 1” frustrate examiners. Always name your diagram and reference it. Vague terminology also undermines precision; for example, use “supply curve shifts left” rather than “supply decreases”, which can be ambiguous. Replace “they” and “it” with the specific agent or concept to avoid ambiguity.
图表缺少标注、移动混乱或者标题只是 “Graph 1” 这样的大路货，都会让考官感到不快。永远为图表命名并引用它。模糊的术语也会削弱精确性；例如，使用“供给曲线向左移动”而不是模棱两可的“供给减少”。用具体的行为主体或概念代替“他们/它”，以避免指代不明。
Time management often causes candidates to rush the evaluation. Practice writing a brief plan within 2–3 minutes before answering. Jot down key definitions, the diagram you will use, and three evaluation points. This plan acts as a safety net and ensures you do not miss crucial elements when pressure mounts.
时间管理不当常导致考生在评估部分草草了事。练习时，在动笔前花 2–3 分钟快速列出简要提纲。写下关键定义、你将使用的图表以及三个评估要点。这份提纲就像一张安全网，确保在压力骤增时你也不会遗漏关键内容。
9. Time Management and Essay Planning | 时间管理与论文规划
For Paper 1, you have 1 hour and 30 minutes, with approximately 45 minutes per full question (part a and part b combined). Allocate around 15–18 minutes for the 10-mark part (a) and 25–28 minutes for the 15-mark part (b). Leave 2–3 minutes for a final sense check. Strong time allocation prevents you from writing a brilliant part (a) and a weak, unfinished part (b).
Paper 1 总时长为 1 小时 30 分钟，每道完整大题（含 (a) 和 (b)）大约分配 45 分钟。其中，10 分的 (a) 题安排 15–18 分钟，15 分的 (b) 题安排 25–28 分钟。留出 2–3 分钟做最后通读。合理的时间分配能防止出现 (a) 题写得很棒，而 (b) 题却写得单薄、未能收尾的情况。
Use a simple planning framework on the question paper: write DEED for part (a) and DEEDE for part (b) at the top. Under each letter, scribble your intended content – the definition, the diagram, the main explanation chain, the evaluation pillars (e.g., equity, efficiency, sustainability). This visual anchor will keep your writing on track even when ideas start flowing.
在题目纸上使用简单的规划框架：在 (a) 题上方写下 DEED，(b) 题上方写下 DEEDE。在每个字母下面，草草记录你打算写的内容——定义、图表、主要解释链条、评估支柱（如公平、效率、可持续性）。这个视觉锚点能让你的写作在思路奔涌时也不偏离轨道。
Remember that part (b) carries more weight. If you are running short on time, prioritise depth of evaluation over excessive descriptive detail. A concise but well-evaluated answer scores higher than a lengthy description with a rushed, superficial conclusion.
要记住 (b) 题权重更高。如果你发现时间不够，优先保证评估的深度，而不是冗长的描述。一份简明但评估充分的答案，得分会高于篇幅虽长但结论仓促、流于表面的答案。
10. Microeconomics Template in Action | 微观经济学模板实操
Let us apply the templates to a typical micro question: “Explain why negative externalities lead to market failure.” For part (a), define market failure and negative externalities. Draw the standard MSC–MPC diagram showing overproduction. Explain that producers only consider private costs, ignoring external costs, leading to Qfree being greater than Qsoc. Add a concise example like smoking or factory pollution.
让我们将模板套用到一道典型的微观题目上：“解释为何负外部性会导致市场失灵。” (a) 题部分，定义市场失灵和负外部性。绘制标准的 MSC–MPC 图，显示过度生产。解释生产者只考虑私人成本、忽略外部成本，导致 Q自由 大于 Q社会最优。加入一个简洁的例子，如吸烟或工厂污染。
For part (b): “Evaluate the use of taxation to correct negative externalities of demerit goods.” Restate the tax diagram from part (a) briefly. Then evaluate using CLASPP: Consequences – reduced consumption, but possible illicit markets. Limitations – hard to measure exact external cost, risk of regressive impact on low-income households. Stakeholders – government gains revenue, addicted consumers may not respond. Perspectives – short-term effectiveness vs long-term need for combination with education. Conclude that taxation is a necessary but insufficient tool, needing complementary policies.
(b) 题部分：“评估运用税收纠正劣质商品负外部性的做法。” 先简要复述 (a) 题中的税收图。然后运用 CLASPP 进行评估：后果——消费减少，但可能催生非法市场。局限性——难以衡量确切的外部成本，存在对低收入家庭产生累退影响的风险。利益相关方——政府获得财政收入，成瘾消费者可能无动于衷。视角——短期有效性与长期需结合教育的需要。结论可以指出，税收是必要但不充分的工具，需要配以补充政策。
Notice how the evaluation moves beyond simple pros and cons. The answer acknowledges partial success of taxation but also highlights its failure to address deeply rooted consumption habits. Such nuance is exactly what distinguishes a high-scoring response.
请注意，这里评估并未止步于简单罗列利弊。答案承认税收的部分成功，但同时也强调它未能解决根深蒂固的消费习惯。这种细致入微正是高分答案的区分度所在。
11. Macroeconomics Template in Action | 宏观经济学模板实操
For a macro question like “Explain the causes of demand-pull inflation,” part (a) should define inflation and demand-pull inflation. Draw an AD–AS diagram where AD shifts right, raising the price level. Explain the causes stepwise: rising consumer confidence, expansionary fiscal policy, low interest rates, or a depreciation of the exchange rate. Use a concrete reference, such as the post-pandemic consumption boom in the United States.
对于像“解释需求拉动型通胀的成因”这样的宏观题目，(a) 题应先定义通货膨胀和需求拉动型通胀。绘制 AD–AS 图，显示 AD 右移、价格水平上升。逐步解释成因：消费者信心上升、扩张性财政政策、低利率或汇率贬值。可引用具体情境，例如美国疫情后的消费热潮。
Part (b) might ask: “Evaluate the effectiveness of monetary policy in controlling inflation.” Start with a brief review of contractionary monetary policy – raising interest rates shifts AD left. Then evaluate: Consequences – reduced investment and consumption, risk of lower economic growth. Limitations – time lags, global factors (imported inflation) and the liquidity trap in deep recessions. Stakeholders – borrowers suffer, savers gain. Perspectives – short-term trade-off between inflation and unemployment (Phillips curve), long-term expectations management. Conclude that monetary policy is a powerful stabilisation tool, but its effectiveness depends on the state of the economy and coordination with fiscal policy.
(b) 题或问：“评估货币政策在控制通胀方面的有效性。” 可先简要回顾紧缩性货币政策——加息使 AD 左移。然后评估：后果——投资和消费减少，经济增速可能下降。局限性——时滞、全球因素（输入型通胀）以及深度衰退中的流动性陷阱。利益相关方——借款人受损、储户受益。视角——通胀与失业的短期权衡（菲利普斯曲线），长期预期管理。结论可以是，货币政策是强有力的稳定工具，但其有效性取决于经济状况以及与财政政策的配合。
This approach shows you can adapt the same templates across all syllabus sections: definitions, diagram, explanation and layered evaluation. The key is to customise your evaluation points to the specific policy and context given in the question.
这种方法说明你可以将相同的模板应用于所有大纲板块：定义、图表、解释以及层层递进的评估。关键在于要把评估要点与题目指定的具体政策和语境紧密结合，写出个性化内容。
12. Final Pre-Exam Checklist | 考前最终检查清单
Before writing your essay, quickly run through this list: Have I identified the command term? Have I written a mini-plan? Am I clear on the diagram I will draw? Do I have at least three evaluative angles ready for part (b)? Will my real-world example be specific and brief?
动笔之前，快速过一遍这份清单：我是否识别出了指令词？我写下简要提纲了吗？我清楚要画什么图吗？我为 (b) 题准备好至少三个评估角度了吗？我的真实世界例子够具体、够简洁吗？
During writing, ask yourself: Is every diagram fully labelled and referenced? Am I linking each paragraph with logical connectors? Is my evaluation structured and does it lead to a clear conclusion? Have I avoided vague statements and unsupported opinions?
写作过程中，问自己：每个图表都完整标注并引用了吗？我是否用逻辑连接词串联每一段？我的评估是否结构清晰，能否导向明确的结论？我有没有避免含糊的陈述和无根据的观点？
After writing, perform a 2-minute sanity check: re-read the conclusion to ensure it answers the question directly.
