1. What is Fiscal Policy? | 什么是财政政策？
Fiscal policy involves the government adjusting its spending levels and tax rates to monitor and influence the nation’s economy. It is implemented through the annual Budget, announced by the Chancellor of the Exchequer, and directly affects the ‘G’ component of aggregate demand (AD).
财政政策是政府通过调整支出水平和税率来监控和影响国家经济的工具。它通过年度预算实施，由财政大臣宣布，并直接影响总需求（AD）中的“G”组成部分。
AD = C + I + G + (X – M)
The main objectives of fiscal policy are to promote economic growth, reduce unemployment, control inflation, and achieve a satisfactory balance of payments. Fiscal policy can be used alongside monetary policy, but it is entirely under the control of the government.
财政政策的主要目标是促进经济增长、降低失业率、控制通货膨胀和实现国际收支平衡。财政政策可与货币政策搭配使用，但它完全由政府掌控。
2. Government Revenue: Taxation and Borrowing | 政府收入：税收与借款
Governments need revenue to fund public services and infrastructure. The main source of revenue is taxation, but governments can also borrow from the financial markets by issuing bonds. Other smaller sources include fees, fines, and profits from state-owned enterprises.
政府需要收入来资助公共服务和基础设施。税收是收入的主要来源，但政府也可以通过发行债券从金融市场借款。其他较小来源包括收费、罚款和国有企业利润。
Taxation can be classified into direct taxes, which are levied on income and wealth, and indirect taxes, which are levied on spending. Direct taxes include income tax, corporation tax, and inheritance tax. Indirect taxes include value-added tax (VAT) and excise duties on goods like alcohol and fuel.
税收可分为直接税和间接税。直接税针对收入和财富征收，包括所得税、公司税和遗产税。间接税针对支出征收，包括增值税（VAT）以及针对酒精和燃料等商品征收的消费税。
3. Types of Taxation and Their Characteristics | 税收类型及其特点
Beyond the direct/indirect classification, taxes are also described as progressive, proportional, or regressive. A progressive tax takes a larger percentage of income from high-income earners (e.g., UK income tax). A proportional tax takes the same percentage of income from everyone (e.g., a flat-rate tax). A regressive tax takes a larger percentage of income from low-income earners (e.g., VAT or excise duties, since low-income households spend a higher proportion of their income).
除了直接/间接分类，税收还被描述为累进、比例或累退。累进税从高收入者身上拿走更大比例的收入（例如英国所得税）；比例税从所有人身上拿走相同比例的收入（例如单一税率税）；累退税从低收入者身上拿走更大比例的收入（例如增值税或消费税，因为低收入家庭将更高比例的收入用于消费）。
| Tax type | Definition | Example |
| Progressive | Takes a higher percentage as income rises | UK income tax bands |
| Regressive | Takes a larger percentage from lower incomes | VAT, excise duties |
| Proportional | Takes the same percentage from all incomes | Flat income tax (20%) |
Knowing the type of tax helps economists evaluate how a fiscal policy change affects inequality and disposable incomes. For example, raising VAT would hit low-income households harder, while raising the top rate of income tax would target high earners.
了解税收类型有助于经济学家评估财政政策变化如何影响不平等和可支配收入。例如，提高增值税对低收入家庭打击更大，而提高最高所得税税率则针对高收入者。
4. Government Expenditure | 政府支出
Government spending can be divided into current expenditure and capital expenditure. Current expenditure includes day-to-day spending on public services such as the salaries of NHS staff, education, defence, and welfare benefits. Capital expenditure refers to long-term investment in infrastructure projects like roads, schools, hospitals, and digital networks.
政府支出可分为经常性支出和资本性支出。经常性支出包括公共服务日常开支，例如 NHS 员工工资、教育、国防和福利金。资本性支出指对道路、学校、医院和数字网络等基础设施项目的长期投资。
In recent years, major areas of UK government spending have included social protection (pensions and benefits), health, and education. Spending decisions reflect the government’s priorities and directly affect aggregate demand and the supply-side capacity of the economy. Capital spending, for instance, can improve productivity and shift the long-run aggregate supply (LRAS) to the right.
近年来，英国政府支出的主要领域包括社会保障（养老金和福利）、卫生和教育。支出决策反映政府的优先事项，并直接影响总需求和经济供给侧能力。例如，资本性支出能提高生产率，使长期总供给（LRAS）向右移动。
5. Budget Balance and National Debt | 预算平衡与国债
The budget balance is the difference between government revenue (mainly tax) and government spending (G). If tax revenue equals spending, the budget is balanced. If tax revenue exceeds spending, there is a budget surplus (T > G). If spending exceeds revenue, there is a budget deficit (G > T).
预算平衡是政府收入（主要是税收）与政府支出（G）之间的差额。如果税收等于支出，预算平衡；如果税收超过支出，出现预算盈余（T > G）；如果支出超过收入，出现预算赤字（G > T）。
A persistent budget deficit requires the government to borrow money, leading to an increase in the national debt. The national debt is the total amount the government owes to its lenders. It is often expressed as a percentage of GDP. A high debt-to-GDP ratio can worry financial markets and increase the cost of borrowing.
持续性预算赤字要求政府借款，导致国债增加。国债是政府欠债权人的总金额，通常以占 GDP 的百分比表示。债务与 GDP 比率过高可能令金融市场担忧，并提高借贷成本。
6. Expansionary Fiscal Policy | 扩张性财政政策
Expansionary fiscal policy involves increasing government spending and/or cutting taxes to boost aggregate demand (AD). It is typically used during a recession or a period of weak economic growth to reduce unemployment and stimulate output. An increase in G directly lifts AD; a tax cut raises disposable income, encouraging consumption (C) and possibly investment (I).
扩张性财政政策通过增加政府支出和/或减税来提振总需求（AD），通常在经济衰退或增长疲软时期使用，以降低失业率并刺激产出。增加 G 直接提升 AD；减税增加可支配收入，鼓励消费（C）并可能促进投资（I）。
For example, during the COVID-19 pandemic, the UK government adopted expansionary policies such as the furlough scheme (high government spending) and temporary VAT cuts for hospitality. These measures aimed to support household incomes and business survival, shifting the AD curve to the right.
例如在 COVID-19 疫情期间，英国政府采取了扩张性政策，如保留就业计划（高政府支出）和临时削减餐饮业增值税。这些措施旨在支持家庭收入和企业生存，使 AD 曲线向右移动。
7. Contractionary Fiscal Policy | 紧缩性财政政策
Contractionary fiscal policy involves reducing government spending and/or increasing taxes to cool down an overheating economy and control inflation. By cutting G or raising taxes, the government reduces aggregate demand, shifting the AD curve to the left. This helps bring down the price level but may also slow economic growth and raise unemployment.
紧缩性财政政策通过减少政府支出和/或增税，为过热的经济降温并控制通货膨胀。通过削减 G 或增税，政府降低总需求，使 AD 曲线向左移动。这有助于降低物价水平，但也可能减缓经济增长并推高失业率。
The UK’s austerity programme after the 2008 financial crisis is a well-known example. The government cut public sector spending and raised VAT to reduce the large budget deficit. While it helped stabilise public finances, critics argue it slowed the recovery and increased inequality.
英国 2008 年金融危机后的紧缩计划是一个著名例子。政府削减公共部门支出并提高增值税，以减少巨额预算赤字。尽管此举有助于稳定公共财政，但批评者认为它延缓了复苏并加剧了不平等。
8. Automatic Stabilisers | 自动稳定器
Automatic stabilisers are built‑in features of the tax and welfare system that dampen fluctuations in economic activity without active government intervention. During a boom, tax revenues rise and welfare spending falls automatically, reducing AD. During a recession, tax revenues fall and welfare spending rises, boosting AD.
自动稳定器是税收和福利制度中固有的机制，无需政府积极干预即可缓解经济波动。经济繁荣时，税收自动增加、福利支出自动减少，抑制 AD；经济衰退时，税收减少、福利支出增加，刺激 AD。
Examples include progressive income taxes and unemployment benefits. In a recession, more people claim jobseeker’s allowance, injecting spending into the economy, while lower incomes mean less tax is collected. These stabilisers help cushion the impact of the business cycle, but they do not eliminate the need for discretionary fiscal policy in deep crises.
例子包括累进所得税和失业救济金。经济衰退时，更多人申请求职者津贴，为经济注入支出，而收入降低意味着征收的税款减少。这些稳定器有助于缓冲经济周期的影响，但在深度危机中仍需要相机抉择的财政政策。
9. Effects of Fiscal Policy on Macroeconomic Objectives | 财政政策对宏观经济目标的影响
Fiscal policy has a direct impact on key macroeconomic indicators. An expansionary policy typically increases economic growth (real GDP rises) and reduces unemployment, but it may cause demand‑pull inflation and worsen the current account (as higher incomes suck in imports). A contractionary policy can reduce inflation and improve the budget deficit, but may raise unemployment and slow growth.
财政政策直接影响关键宏观经济指标。扩张性政策通常提高经济增长（实际 GDP 上升）并降低失业率，但可能引发需求拉动型通货膨胀并恶化经常账户（因为收入增加引起进口增加）。紧缩性政策可降低通胀并改善预算赤字，但可能推高失业率并减缓增长。
Fiscal policy can also influence income distribution. Progressive taxes and targeted welfare spending (such as child benefit or universal credit) can reduce inequality. Meanwhile, cuts to public services may disproportionately affect lower‑income groups. The overall effect depends on the specific mix of tax and spending changes.
财政政策还能影响收入分配。累进税和有针对性的福利支出（如儿童福利或通用福利金）可减少不平等。同时，削减公共服务可能对低收入群体影响更大。总体效果取决于税收和支出变化的具体组合。
10. Evaluation of Fiscal Policy | 对财政政策的评估
The effectiveness of fiscal policy depends on several factors. Time lags are a major limitation: it takes time to design and implement policy changes, and even longer for their effects to be felt. Additionally, expansionary policy may crowd out private investment if government borrowing pushes up interest rates, reducing private sector spending (I).
财政政策的有效性取决于多个因素。时滞是一个主要局限：设计和实施政策变化需要时间，其效果显现甚至更慢。此外，如果政府借款推高利率、挤出私人投资（I），扩张性政策可能对私人部门支出产生挤出效应。
Other considerations include the size of the multiplier effect. If consumers save tax cuts or import more goods, the boost to AD may be smaller than expected. Political pressures can also lead to short‑term popular decisions rather than long‑term stability. Nevertheless, in deep recessions when interest rates are near zero, fiscal policy becomes crucial because monetary policy is less effective.
其他考虑因素包括乘数效应的大小。如果消费者将减税所得储蓄起来或购买更多进口商品，AD 的提升可能小于预期。政治压力也可能导致短视的讨好性决策，而非追求长期稳定。尽管如此，在利率接近零的深度衰退中，货币政策效果有限，此时财政政策至关重要。
A well‑designed fiscal rule, such as limiting the cyclically‑adjusted deficit, can improve credibility. Recent UK examples, such as the reduction in the higher income tax rate in 2022 (mini‑budget) and its subsequent reversal, show how financial markets react to perceived unsustainability in fiscal plans.
精心设计的财政规则（如限制经周期调整的赤字）可提高可信度。近期的英国案例，如 2022 年迷你预算中降低高收入所得税税率及其随后的逆转，表明金融市场会对财政计划的不可持续性预期做出反应。
