财政政策是政府用来管理经济的最重要工具之一。在 WJEC GCSE 经济课程中，你需要了解税收和政府支出如何影响总需求、就业、通货膨胀和经济增长。这份复习指南将拆解所有你需要掌握的关键概念、图表和考试技巧。
1. What is Fiscal Policy? | 什么是财政政策？
Fiscal policy involves the use of government spending and taxation to influence the level of economic activity and achieve macroeconomic objectives. It is conducted by the government (the Treasury), not the central bank.
财政政策涉及使用政府支出和税收来影响经济活动水平并实现宏观经济目标。它由政府（财政部）实施，而不是中央银行。
The main macroeconomic objectives include sustainable economic growth, low unemployment, low and stable inflation, and a satisfactory balance of payments.
主要宏观经济目标包括可持续经济增长、低失业率、低而稳定的通货膨胀以及令人满意的国际收支平衡。
Expansionary fiscal policy is used to boost AD during a recession, while contractionary policy cools down an overheating economy.
扩张性财政政策用于在经济衰退时提振总需求，而紧缩性政策则用于给过热的经济降温。
2. The Government Budget: Revenue and Spending | 政府预算：收入与支出
The government budget is a forecast of its expected revenue (mainly taxes) and planned expenditure for the coming financial year.
政府预算是对下一财政年度预期收入（主要是税收）和计划支出的预测。
Revenue comes from direct taxes (income tax, corporation tax), indirect taxes (VAT, excise duties), and non-tax revenue (fines, profits from state-owned enterprises).
收入来自直接税（所得税、公司税）、间接税（增值税、消费税）和非税收入（罚款、国有企业利润）。
Spending includes current spending (such as public sector salaries, NHS running costs) and capital spending (infrastructure projects like roads, schools, hospitals).
支出包括经常性支出（如公共部门工资、NHS 运营成本）和资本支出（如道路、学校、医院等基础设施项目）。
3. Types of Taxation | 税收类型
Taxes can be classified as progressive, proportional, or regressive.
税收可以分为累进税、比例税和累退税。
A progressive tax takes a larger percentage of income from high-income earners (e.g. UK income tax).
累进税从高收入者那里取走较大比例的收入（例如英国所得税）。
A proportional tax takes the same percentage from all income levels (e.g. some flat taxes).
比例税对所有收入水平征收相同比例的税（例如一些统一税）。
A regressive tax takes a larger percentage from low-income earners (e.g. VAT as a share of income).
累退税从低收入者那里取走较大比例的收入（例如增值税占收入的比例）。
Direct taxes are levied on income and wealth, while indirect taxes are on spending.
直接税对收入和财富征收，而间接税对支出征收。
| Type / 类别 | Examples / 例子 |
|---|---|
| Direct Taxes (直接税) | Income Tax (所得税), Corporation Tax (公司税), Capital Gains Tax (资本利得税) |
| Indirect Taxes (间接税) | VAT (增值税), Excise Duties (消费税), Customs Duties (关税) |
4. Categories of Government Spending | 政府支出的类别
Government spending is divided into transfer payments, current spending, and capital spending.
政府支出分为转移支付、经常性支出和资本支出。
Transfer payments are welfare benefits like pensions and unemployment benefits – they do not directly contribute to output but redistribute income.
转移支付是养老金和失业救济金等福利金——它们不直接贡献产出，但会再分配收入。
Current spending is on goods and services consumed within a year, e.g. salaries of teachers and doctors.
经常性支出用于一年内消费的商品和服务，例如教师和医生的工资。
Capital spending adds to the economy’s productive capacity, e.g. new hospitals, high-speed rail.
资本支出增加经济的生产能力，例如新医院、高速铁路。
A summary of spending categories:
支出类别总结：
| Category / 类别 | Description / 描述 |
|---|---|
| Transfer Payments (转移支付) | State pensions, Jobseeker’s Allowance, Child Benefit. No exchange of goods/services. (国家养老金、求职者津贴、儿童福利。不涉及商品/服务交换。) |
| Current Spending (经常性支出) | Day-to-day running costs: NHS salaries, schools, defence. (日常运营成本：NHS 工资、学校、国防。) |
| Capital Spending (资本支出) | Infrastructure investment: roads, railways, new hospitals. (基础设施投资：道路、铁路、新医院。) |
5. Budget Balance, Deficit and Surplus | 预算平衡、赤字和盈余
A balanced budget occurs when government revenue equals spending (G = T).
当政府收入等于支出时（G = T），出现预算平衡。
A budget deficit (G > T) means the government is borrowing to cover the shortfall.
预算赤字（G > T）意味着政府正在借款以弥补缺口。
A budget surplus (T > G) means revenue exceeds spending, allowing the government to pay down debt.
预算盈余（T > G）意味着收入超过支出，政府可以偿还债务。
The national debt is the cumulative total of past government borrowing.
国债是过去政府借款的累计总额。
Budget Deficit: G > T | Budget Surplus: T > G
预算赤字：G > T | 预算盈余：T > G
6. Expansionary Fiscal Policy | 扩张性财政政策
Expansionary fiscal policy aims to increase aggregate demand (AD) to reduce unemployment and stimulate growth.
扩张性财政政策旨在增加总需求（AD），以减少失业并刺激增长。
It involves increasing government spending, cutting taxes, or both.
它涉及增加政府支出、减税或两者兼施。
For example, a government might lower income tax, boosting household disposable income and consumption (C), or increase infrastructure spending (G).
例如，政府可能降低所得税，提高家庭可支配收入和消费（C），或增加基础设施支出（G）。
An increase in AD shifts the AD curve to the right, leading to higher real GDP and lower unemployment, but may cause demand-pull inflation.
AD 增加使 AD 曲线向右移动，导致实际 GDP 上升和失业率下降，但可能引起需求拉动型通货膨胀。
7. Contractionary Fiscal Policy | 紧缩性财政政策
Contractionary fiscal policy is used to reduce aggregate demand, often to combat inflation.
紧缩性财政政策用于减少总需求，通常是为了对抗通货膨胀。
It involves cutting government spending, raising taxes, or both.
它涉及削减政府支出、提高税收或两者兼施。
Higher taxes reduce disposable income and consumption, while lower spending directly reduces G.
提高税收会减少可支配收入和消费，而降低支出直接减少 G。
AD shifts left, lowering the price level and possibly reducing output temporarily.
AD 向左移动，降低价格水平，并可能暂时减少产出。
8. How Fiscal Policy Affects Economic Objectives | 财政政策如何影响经济目标
Economic Growth: expansionary policy boosts AD, encouraging firms to increase output; contractionary does the opposite.
经济增长：扩张性政策提振总需求，鼓励企业增加产出；紧缩性政策相反。
Unemployment: higher AD raises demand for labour, reducing cyclical unemployment.
失业：更高的总需求会增加对劳动力的需求，减少周期性失业。
Inflation: demand-pull inflation may result from excessive expansionary policy, while contractionary reduces it.
通货膨胀：过度的扩张性政策可能引起需求拉动型通货膨胀，而紧缩性政策会降低它。
Income Distribution: taxation and welfare benefits can redistribute income; progressive taxes reduce inequality.
收入分配：税收和福利救济金可以再分配收入；累进税减少不平等。
External Balance: increased government borrowing may worsen the trade deficit if it boosts imports.
外部平衡：如果政府借款增加刺激了进口，可能会恶化贸易逆差。
9. Automatic Stabilisers vs Discretionary Fiscal Policy | 自动稳定器与自主财政政策
Automatic stabilisers are features of the tax and welfare system that automatically moderate the economy without government action.
自动稳定器是税收和福利体系的特点，它们无需政府行动就能自动调节经济。
Example: progressive income tax automatically takes more in taxes when incomes rise, slowing growth; unemployment benefits rise during a recession, supporting spending.
例子：累进所得税在收入增加时自动收取更多税款，减缓增长；经济衰退时失业救济金增加，支持支出。
Discretionary fiscal policy involves deliberate changes in taxes or spending, such as a fiscal stimulus package.
自主财政政策涉及有意改变税收或支出，例如财政刺激方案。
Automatic stabilisers are predictable and do not suffer from time lags as much as discretionary policy.
自动稳定器可预测，且不像自主政策那样受到时滞的影响。
10. Limitations and Evaluation of Fiscal Policy | 财政政策的局限性与评估
Time lags: recognition, decision, and implementation lags can make fiscal policy less effective.
时滞：识别时滞、决策时滞和实施时滞可能使财政政策效果变差。
Crowding out: increased government borrowing may drive up interest rates, reducing private investment.
挤出效应：政府借款增加可能推高利率，减少私人投资。
Public sector debt: persistent deficits can lead to high national debt, causing future interest burdens and reduced fiscal space.
公共部门债务：持续的赤字可能导致高额国债，造成未来的利息负担并缩小财政空间。
Political pressures: politicians may use expansionary policy before elections, causing a political business cycle, even if it harms long-term stability.
政治压力：政客可能在选举前使用扩张性政策，造成政治经济周期，即使这会损害长期稳定。
Effectiveness depends on the size of the multiplier and the state of the economy (e.g. spare capacity).
有效性取决于乘数的大小和经济状况（例如闲置产能）。
Supply-side effects: tax cuts can improve incentives to work and invest, shifting LRAS.
供给侧效应：减税可以改善工作和投资激励，移动 LRAS。
11. Real-World Context: UK Fiscal Policy Examples | 现实背景：英国财政政策例子
After the 2008 financial crisis, the UK government cut VAT temporarily and increased public spending as an expansionary measure.
2008 年金融危机后，英国政府暂时降低增值税并增加公共支出，作为扩张性措施。
During COVID-19, the furlough scheme and business grants were massive discretionary fiscal expansions, increasing government borrowing to record levels.
在 COVID-19 疫情期间，强制休假计划和商业补助金是大规模自主财政扩张，使政府借款升至创纪录水平。
Recent cost-of-living support payments and energy price caps are further examples of targeted fiscal policy.
最近的生活成本支持付款和能源价格上限是针对性财政政策的进一步例子。
These examples show the trade-off between supporting the economy and managing public debt.
这些例子展示了支持经济与管理公共债务之间的权衡。
12. Exam Tips for WJEC GCSE Economics | WJEC GCSE 经济考试技巧
Define key terms: always start a question on fiscal policy by defining it.
定义关键术语：开始回答财政政策问题时一定要先定义它。
Use diagrams: AD/AS curves shifts are vital; clearly label axes and show initial and final equilibria.
使用图表：AD/AS 曲线移动至关重要；清晰标注坐标轴并显示初始和最终均衡。
Evaluate: mention limitations like time lags, crowding out, and the impact on different stakeholders.
评估：提及时滞、挤出效应和对不同利益相关者的影响等局限性。
Apply real examples: refer to UK recent fiscal events to demonstrate application.
应用实例：引用英国最近的财政事件来展示应用能力。
Watch command words: ‘Explain’, ‘Analyse’, ‘Evaluate’ have different depth requirements – make sure your response matches.
注意指令词：‘Explain’（解释）、‘Analyse’（分析）、‘Evaluate’（评估）有不同的深度要求——确保你的回答与之匹配。
Link back to macroeconomic objectives whenever possible.
