Government Macroeconomic Objectives: Stability and Growth | 政府的宏观经济目标：稳定与增长

📚 Government Macroeconomic Objectives: Stability and Growth | 政府的宏观经济目标：稳定与增长

Macroeconomic objectives are the targets that governments set for the overall performance of the economy. In the CIE IGCSE Economics syllabus, the main goals include economic growth, low unemployment, low and stable inflation, and a stable balance of payments. These objectives are also described as achieving stability and growth.

宏观经济目标是指政府为整个经济体的运行所设定的目标。在 CIE IGCSE 经济学考纲中，主要目标包括经济增长、低失业率、低且稳定的通胀率以及稳定的国际收支。我们也将这些目标概括为实现经济的稳定与增长。

1. What Are Macroeconomic Objectives? | 什么是宏观经济目标？

A macroeconomic objective is a desired outcome for the whole economy, not just for one industry or region. Governments use these objectives to guide their policy decisions and to measure the success of their economic management.

宏观经济目标是针对整个经济体而不仅限于某个行业或地区的期望结果。政府利用这些目标来指导政策决策，并衡量其经济管理的成功程度。

The key objectives in the CIE IGCSE syllabus are:

CIE IGCSE 考纲中的核心目标包括：

Economic growth – increasing the real output of goods and services over time.
Low unemployment – ensuring that most people who are willing and able to work can find jobs.
Low and stable inflation – keeping the general price level rising slowly and predictably.
Stable balance of payments – avoiding large or persistent deficits or surpluses in international trade.

经济增长——实际产出的商品和服务随时间不断增加。
低失业率——确保大多数愿意且能够工作的人能找到工作。
低且稳定的通胀——使总体价格水平缓慢且可预测地上升。
稳定的国际收支——避免国际贸易中出现长期的大额逆差或顺差。

Some governments also aim for redistribution of income and protection of the environment, but the four above are the core macroeconomic goals.

部分政府还会关注收入再分配和环境保护，但上述四项目标是核心的宏观经济目标。

2. Economic Growth | 经济增长

Economic growth is defined as an increase in the real output of an economy over time. It is usually measured by the percentage change in real Gross Domestic Product (GDP). Real GDP measures the value of all goods and services produced, adjusted for inflation.

经济增长是指一个经济体实际产出随时间不断增加。通常用实际国内生产总值（GDP）的百分比变化来衡量。实际 GDP 衡量的是所有商品和服务的价值，并已调整通货膨胀的影响。

Growth can be represented by an outward shift of a country’s Production Possibility Frontier (PPF) or by an increase in aggregate demand and aggregate supply.

增长可以通过生产可能性边界（PPF）外移来表示，也可以通过总需求和总供给的增加来表示。

Economic Growth = (Real GDP year₂ − Real GDP year₁) ÷ Real GDP year₁ × 100%

Why is growth important?

为什么增长很重要？

Rising incomes: higher GDP per capita can improve living standards.
More employment: as firms expand, they hire more workers.
Better public services: higher tax revenue allows more spending on health and education.

收入提高：人均 GDP 增加可以提高生活水平。
更多就业：企业扩张时会雇佣更多劳动力。
更好的公共服务：税收增加使得政府能够在医疗和教育上投入更多。

However, growth can also cause negative externalities, such as pollution and congestion. The quality of growth matters, not just the quantity.

然而，增长也可能带来负面外部性，例如污染和交通拥堵。增长的质量同样重要，而不仅仅是数量。

3. Low Unemployment | 低失业率

Unemployment occurs when people who are willing and able to work at the going wage rate cannot find jobs. The unemployment rate is the percentage of the labour force that is out of work. A government objective is to keep unemployment as low as possible, often described as full employment.

失业是指那些愿意并且能够在现行工资率下工作的人找不到工作。失业率是指劳动力中处于失业状态的人所占的百分比。政府的目标是尽可能降低失业率，常被称为充分就业。

There are several types of unemployment:

失业有几种类型：

Cyclical unemployment – caused by a fall in aggregate demand during a recession.
Structural unemployment – caused by changes in the structure of the economy, such as the decline of an industry.
Frictional unemployment – occurs when workers are between jobs, searching for a better match.
Seasonal unemployment – occurs when demand for labour varies with the season.

周期性失业——由经济衰退期间总需求下降引起。
结构性失业——由经济结构调整引起，例如某个行业衰落。
摩擦性失业——工人正处于换工作的间隙，在寻找更合适的岗位。
季节性失业——劳动力需求随季节变化而产生。

High unemployment imposes costs on individuals, families and the government. Workers lose income, the government pays more in welfare benefits and receives less tax revenue, and society loses potential output.

高失业率会给个人、家庭和政府带来损失。劳动者失去收入，政府要支付更多的福利金且税收减少，整个社会也损失了潜在产出。

4. Low and Stable Inflation | 低且稳定的通胀

Inflation is a sustained rise in the general price level. The rate of inflation is measured by the Consumer Price Index (CPI). A low and stable inflation rate helps households and firms plan for the future, and protects the value of money.

通胀是指总体价格水平的持续上升。通胀率通常用消费者价格指数（CPI）来衡量。低且稳定的通胀率有助于家庭和企业规划未来，并保护货币的价值。

There are two main causes of inflation:

通货膨胀主要有两种成因：

Demand-pull inflation – when aggregate demand grows faster than aggregate supply, pushing prices up.
Cost-push inflation – when the costs of production rise, such as wages or raw materials, causing firms to raise prices.

需求拉动型通胀——总需求增长快于总供给，从而推高价格。
成本推动型通胀——生产成本上升，例如工资或原材料上涨，导致企业提高价格。

Why is high inflation harmful?

为什么高通胀是有害的？

It reduces the purchasing power of money and erodes savings.
It creates uncertainty, making it harder for firms to invest.
It can hurt international competitiveness if domestic prices rise faster than those of trading partners.

它降低了货币的购买力并侵蚀储蓄的实际价值。
它带来不确定性，使企业更难以进行投资。
如果国内价格上涨速度快于贸易伙伴国，就会损害国际竞争力。

Stable inflation means a rate that is low and predictable, allowing businesses to set prices with confidence and workers to negotiate wages fairly.

稳定的通胀是指通胀率低且可预测，使企业能够有信心地制定价格，也使工人能够公平地谈判工资。

5. Balance of Payments Stability | 国际收支稳定

The balance of payments records all financial transactions between a country and the rest of the world. The current account of the balance of payments includes trade in goods, trade in services, income and transfers. A persistent deficit or surplus can indicate macroeconomic instability.

国际收支记录一国与世界其他国家之间的所有金融交易。国际收支经常账户包括商品贸易、服务贸易、收入和转移支付。长期持续的逆差或顺差可能表明宏观经济不稳定。

For a government, the aim is usually to avoid large and persistent current account deficits. A current account deficit means that a country is spending more on imports than it earns from exports.

对政府而言，目标通常是避免长期大额的经常账户逆差。经常账户逆差意味着该国的进口支出大于其出口收入。

Why is instability in the balance of payments a problem?

为什么国际收支不稳定会成为一个问题？

A large deficit may have to be financed by borrowing from other countries, increasing foreign debt.
It may put downward pressure on the exchange rate, making imports more expensive.
It can indicate a loss of competitiveness in international markets.

巨额逆差可能必须通过向他国借款来融资，从而增加外债。
它可能给汇率带来下行压力，使进口商品更加昂贵。
它可能表明一国在国际市场上的竞争力正在下降。

On the other hand, a very large surplus is not always good either, because it may reflect low domestic consumption or cause friction with trading partners.

另一方面，非常大的顺差也并非总是好事，因为它可能反映国内消费不足，或者引发与贸易伙伴之间的摩擦。

6. Stability in the Macroeconomic Environment | 宏观经济环境的稳定

Stability in macroeconomics means that key variables such as GDP growth, inflation and employment do not fluctuate wildly. Stability provides a favourable environment for saving, investment and long-term planning.

宏观经济中的稳定是指 GDP 增长、通胀和就业等关键变量不会剧烈波动。稳定为储蓄、投资和长期规划提供了有利的环境。

An unstable economy might experience booms and busts. Rapid growth might be followed by a sudden recession, causing unemployment and business failures. This volatility discourages investment because the future is uncertain.

不稳定的经济体可能会经历繁荣与萧条。快速增长之后可能突然出现衰退，导致失业和企业倒闭。这种波动性使未来充满不确定性，从而抑制投资。

Therefore, governments aim not only to achieve growth, but to achieve sustainable growth – growth that can continue without causing high inflation or external imbalances.

因此，政府的目标不仅仅是实现增长，而是实现可持续的增长——一种能够持续且不会引发高通胀或外部失衡的增长。

Stability also includes a stable financial system, where banks and other financial institutions operate safely, so that consumers’ savings are protected.

稳定还包括金融体系的稳定，即银行和其他金融机构安全运行，从而保护消费者的储蓄。

7. Policies to Achieve Growth and Stability | 实现增长与稳定的政策

Governments use two main types of policy: demand-side policies and supply-side policies.

政府使用两大类政策：需求侧政策和供给侧政策。

Demand-side policies aim to influence aggregate demand. Fiscal policy involves changing government spending and taxation. Monetary policy involves changing interest rates and the money supply.

需求侧政策旨在影响总需求。财政政策通过改变政府支出和税收来实施。货币政策通过改变利率和货币供应来实施。

For example, during a recession the government may reduce taxes and increase spending to boost aggregate demand. The central bank may lower interest rates to encourage borrowing and investment.

例如，在经济衰退期间，政府可能减税并增加支出以刺激总需求。中央银行可能降低利率以鼓励借贷和投资。

Supply-side policies aim to increase the productive capacity of the economy. These include improving education and training, encouraging innovation, reducing regulations and improving infrastructure.

供给侧政策旨在提高经济的生产能力。这些措施包括改善教育和培训、鼓励创新、减少管制和改善基础设施。

The table below summarises how policies may affect growth and stability:

下表总结了政策如何影响增长与稳定：

Policy type \| 政策类型	Examples \| 举例	Effect on growth \| 对增长的影响	Effect on stability \| 对稳定的影响
Expansionary fiscal policy 扩张性财政政策	Higher government spending, lower taxes 增加政府支出、减税	Increases aggregate demand and growth 增加总需求和增长	May cause inflation if economy is near full capacity 若经济接近充分产能，可能引发通胀
Contractionary monetary policy 紧缩性货币政策	Higher interest rates 提高利率	Slows down growth in the short run 短期放慢增长	Reduces inflation and stabilises prices 降低通胀并稳定物价
Supply-side policies 供给侧政策	Education, deregulation, investment incentives 教育、放松管制、投资激励	Shifts LRAS outward, raising potential growth 使长期总供给右移，提高潜在增长	Supports long-term stability without inflation 在不引发通胀的情况下支持长期稳定

8. Conflicts Between Objectives | 目标之间的冲突

Macroeconomic objectives are not always compatible. A government may find it hard to achieve growth and stability at the same time. These conflicts are known as policy trade-offs.

宏观经济目标并非总能同时实现。政府可能会发现很难同时达到增长和稳定。这些矛盾被称为政策权衡取舍。

One classic conflict is between economic growth and low inflation. If the government stimulates demand to increase growth, the economy may overheat, and demand-pull inflation may rise. Thus faster growth can jeopardise price stability.

一个典型的冲突是经济增长与低通胀之间的冲突。如果政府刺激需求以促进增长，经济可能过热，进而引发需求拉动型通胀。因此，更快的增长可能危及价格稳定。

Another conflict is between growth and the balance of payments. As income rises, consumers often spend more on imports, causing the current account deficit to widen. This means growth may create external instability.

另一个冲突是增长与国际收支之间的冲突。随着收入增加，消费者往往会进口更多商品，导致经常账户逆差扩大。这意味着增长可能造成外部不稳定。

Similarly, policies to reduce inflation, such as raising interest rates, may reduce consumer spending and investment, leading to slower growth and higher unemployment.

同样，为降低通胀而采取的加息等政策可能会减少消费和投资，导致增长放缓和失业上升。

These trade-offs mean the government must decide which objective is most important at a particular time. It may also try to use a balanced combination of policies to minimise the conflicts.

这些权衡意味着政府必须判断在特定时期哪项目标最重要。它也可能尝试通过多种政策的组合来尽量减少冲突。

9. Evaluation of Macroeconomic Objectives | 对宏观经济目标的评价

When evaluating government macroeconomic objectives, it is important to consider both the benefits and the limitations.

在评价政府的宏观经济目标时，既要考虑其益处，也要考虑其局限性。

On the one hand, targeting growth and stability helps create jobs, raise living standards and maintain confidence in the economy. Low inflation protects savers and pensioners, while stable growth attracts foreign investment.

一方面，以增长和稳定为目标有助于创造就业、提高生活水平并保持经济信心。低通胀保护储蓄者和养老金领取者，而稳定增长则吸引外国投资。

On the other hand, the measurement of these objectives has weaknesses. GDP per capita may mask inequality, and a low unemployment rate might hide underemployment or workers who have given up searching for jobs.

另一方面，这些目标的衡量方式也存在不足。人均 GDP 可能掩盖分配不均，而低失业率可能掩盖就业不充分或放弃找工作的人群。

Moreover, achieving one objective often comes at the cost of another. For example, a government may boost growth to win political popularity but ignore inflation, causing long-term harm.

此外，实现一个目标往往以牺牲另一个目标为代价。例如，政府可能为了赢得民心而刺激增长，却忽视了通胀，从而造成长期损害。

Therefore, policymakers must evaluate the trade-offs carefully and use both short-run demand-side policies and long-run supply-side policies to achieve a balance between stability and growth.

因此，政策制定者必须谨慎权衡利弊，综合运用短期的需求侧政策和长期的供给侧政策，在稳定与增长之间取得平衡。

10. Summary and Exam Focus | 总结与考试重点

For the CIE IGCSE Economics exam, you should be able to define each macroeconomic objective, explain why it is important, and discuss possible conflicts between objectives. You should also understand how fiscal policy and monetary policy are used to achieve stability and growth.

对于 CIE IGCSE 经济学的考试，你应该能够定义每一项宏观经济目标，解释其重要性，并讨论各目标之间可能的冲突。你还需要理解如何使用财政政策和货币政策来实现稳定与增长。

Remember to use real-world examples where possible. For instance, many governments set an inflation target of around 2% per year. They also aim for a stable GDP growth rate of about 2–3% per year, although the appropriate rate depends on the country’s circumstances.

记住，尽可能使用现实世界的例子。例如，许多政府将年度通胀目标设定在 2% 左右。他们还会设定每年约 2–3% 的稳定 GDP 增速目标，但合适的增长率取决于该国的具体情况。

Key formulae that may appear:

一些可能考到的公式：

Rate of inflation = (CPI this year − CPI last year) ÷ CPI last year × 100%
Unemployment rate = unemployed workers ÷ total labour force × 100%
GDP per capita = Real GDP ÷ population

通胀率 =（今年 CPI − 去年 CPI）÷ 去年 CPI × 100%
失业率 = 失业人数 ÷ 劳动力总人数 × 100%
人均 GDP = 实际 GDP ÷ 人口

In evaluation questions, use phrases like ‘on the one hand’, ‘however’, ‘in the short run’ and ‘in the long run’ to show balanced judgement.

在评估类题目中，可以使用“一方面”、“然而”、“短期来看”和“长期来看”等表达，以展示平衡的判断。

Ultimately, the aim of macroeconomic policy is not just to make numbers grow, but to improve the wellbeing of citizens in a sustainable and stable way.

归根结底，宏观经济政策的目标不只是让数字增长，而是以可持续和稳定的方式提高公民的福祉。
