失业是最重要的宏观经济指标之一，在 IGCSE 经济考试中出现频率很高。理解它的衡量方法、类型、成因、后果以及政策应对是取得高分的关键。本文将逐一拆解你必需掌握的考点，并配以中英双语简明解析，让复习更加高效。

1. What is Unemployment? | 什么是失业？

Unemployment refers to people of working age who are actively seeking work but are unable to find a job. Only those who are willing and able to work are counted as unemployed. People who have given up looking for a job, full-time students, the retired, and the sick are not part of the labour force.

失业指的是处于劳动年龄、正在积极寻找工作但无法找到工作的人群。只有那些愿意并且有能力工作的人才被计入失业人口。放弃找工作的人、全日制学生、退休人员和病人不属于劳动力。

The labour force, also known as the working population, is the total number of people employed or actively seeking employment. The unemployment rate is calculated as (number of unemployed ÷ labour force) × 100%.

劳动力，也称就业人口，是就业人数加上积极寻找工作人数的总和。失业率计算方式为（失业人数 ÷ 劳动力）× 100%。

2. How is Unemployment Measured? | 失业如何衡量？

Two main measures are used to calculate unemployment: the claimant count and the labour force survey. The claimant count records the number of people receiving unemployment-related benefits. It is easy to obtain but often underestimates true unemployment because not everyone is eligible for benefits.

有两种衡量失业的主要方法：申请失业救济金人数和劳动力调查。申请人数记录的是领取失业救济金的人数。这种方法容易获取，但往往会低估真实失业水平，因为并非所有人都符合申领资格。

The labour force survey (LFS) uses a sample of households and asks whether people are actively seeking work. It is more accurate and considers those not claiming benefits. The LFS is used by the International Labour Organization (ILO) to standardise international comparisons.

劳动力调查通过对住户抽样，询问人们是否积极寻找工作。它更加准确，也考虑到了未申领救济金的人。国际劳工组织采用劳动力调查来统一国际比较标准。

3. Types of Unemployment | 失业的类型

Economists classify unemployment into several types based on its underlying causes. The main types you need to know for IGCSE are cyclical, structural, frictional, and seasonal unemployment. Each type requires a different policy response.

经济学家根据根本成因将失业分为几种类型。IGCSE 阶段你需要掌握的主要类型有周期性、结构性、摩擦性和季节性失业。每种类型需要不同的政策应对。

Understanding these categories helps explain why unemployment can exist even when an economy is growing. Some types are considered more serious than others, and some are inevitable in any dynamic economy.

理解这些分类有助于解释为什么即使经济在增长，失业依然存在。有些类型比其他更为严重，而有些则在任何富有活力的经济体中都不可避免。

4. Cyclical Unemployment | 周期性失业

Cyclical unemployment, also called demand-deficient unemployment, occurs during a downturn in the business cycle. When aggregate demand falls, firms produce less and need fewer workers. This is closely linked to recessions and negative output gaps.

周期性失业，也称需求不足型失业，发生在经济周期的下行阶段。当总需求下降时，企业减产并减少用工需求。这与经济衰退和负产出缺口紧密相关。

The most famous example is the Great Depression of the 1930s, where a collapse in demand pushed unemployment above 25% in some countries. During the COVID-19 pandemic, many economies also experienced a sharp rise in cyclical unemployment.

最著名的例子是 20 世纪 30 年代的大萧条，需求崩溃使一些国家的失业率飙升至 25% 以上。在新冠疫情期间，许多经济体的周期性失业也急剧上升。

5. Structural Unemployment | 结构性失业

Structural unemployment arises from a mismatch between the skills of workers and the requirements of available jobs. This often results from long-term changes in an economy, such as deindustrialisation, technological advancement, or shifts in comparative advantage.

结构性失业产生于工人技能与现有职位要求之间的不匹配。这通常源于经济的长期变化，比如去工业化、技术进步或比较优势的转变。

Examples include coal miners losing jobs as countries switch to renewable energy, or manufacturing workers being replaced by automation. Retraining and education are key to reducing this type of unemployment, but they take time to be effective.

例子包括国家转向可再生能源导致煤矿工人失业，或制造业工人被自动化取代。再培训和提升教育水平是减少这类失业的关键，但需要时间才能见效。

6. Frictional Unemployment | 摩擦性失业

Frictional unemployment is short-term unemployment that occurs when people are between jobs, entering the labour market for the first time, or re-entering after a break. It is often seen as a healthy part of a flexible economy.

摩擦性失业是人们在换工作、首次进入劳动力市场或暂歇后重返时的短期失业。它通常被视为经济灵活的良好表现。

Imperfect information in the job market means that workers and employers take time to find the right match. Frictional unemployment is generally lower when information flows more freely, for example through online job portals and efficient employment agencies.

就业市场存在信息不完善，意味着工人和雇主需要时间找到合适的匹配。当信息流动更顺畅时，例如通过在线招聘门户和高效的就业机构，摩擦性失业通常会降低。

7. Seasonal Unemployment | 季节性失业

Seasonal unemployment happens when people are out of work at certain times of the year because demand for their labour falls regularly. Industries affected include tourism, agriculture, and construction.

季节性失业发生在一年中某些时段需求有规律地下降时，受影响行业包括旅游业、农业和建筑业。

For example, lifeguards may be unemployed in winter, and ski instructors in summer. Because these patterns are predictable, governments and businesses can plan ahead, but the unemployment is still counted in official statistics.

例如，救生员在冬季可能失业，滑雪教练在夏季可能失业。由于这些模式可预测，政府和企业能够提前规划，但这种失业仍被计入官方统计。

8. Causes of Unemployment | 失业的原因

Unemployment can be caused by both demand-side and supply-side factors. Demand-side causes include a fall in consumer spending, a drop in exports, or contractionary fiscal and monetary policy. This leads to cyclical unemployment.

失业可能由需求侧和供给侧因素共同导致。需求侧原因包括消费支出下降、出口减少，或紧缩性财政和货币政策。这会导致周期性失业。

Supply-side causes relate to the structure of the labour market. High minimum wages above the equilibrium level can create classical unemployment. Generous welfare benefits may reduce the incentive to seek work, contributing to voluntary unemployment.

供给侧原因与劳动力市场的结构有关。高于均衡水平的最低工资可能导致经典失业。慷慨的福利救济可能削弱工作积极性，带来自愿失业。

Labour immobility, both geographical and occupational, also contributes to structural unemployment. Workers may be unable to move to where jobs are or lack the skills needed for new types of work.

劳动力在地理和职业上的不流动也会导致结构性失业。工人可能无法迁往有工作机会的地区，或缺乏从事新型工作所需的技能。

9. Consequences of Unemployment | 失业的后果

The consequences of unemployment are serious and wide-ranging. For the individual, unemployment means loss of income, lower living standards, and possible health problems such as stress and depression. Prolonged unemployment leads to loss of skills and reduces future employability.

失业的后果广泛而严重。对个人而言，失业意味着收入损失、生活水平下降，以及可能产生压力、抑郁等健康问题。长期失业会导致技能流失，降低未来就业能力。

For the economy, unemployment represents a waste of resources. The economy operates inside its production possibility curve (PPC), producing less than its potential output. This leads to lower GDP and reduced tax revenue for the government.

对经济来说，失业是一种资源浪费。经济运行在生产可能性曲线（PPC）内部，产出低于潜在产出。这会导致 GDP 下降和政府税收减少。

Society as a whole also suffers. Higher unemployment is linked to increased crime rates, social unrest, and greater inequality. Governments may need to spend more on benefits and social services while collecting less tax, worsening the fiscal position.

整个社会也会受损。较高失业率与犯罪率上升、社会动荡和更严重的不平等有关。政府可能需要在福利和社会服务上增加支出，而税收收入减少，从而恶化财政状况。

10. Policies to Reduce Unemployment | 减少失业的政策

To reduce cyclical unemployment, governments can use expansionary fiscal and monetary policies. Cutting taxes and increasing government spending boosts aggregate demand. Lowering interest rates and increasing the money supply encourages borrowing and investment.

为了减少周期性失业，政府可以采用扩张性财政和货币政策。减税和增加政府支出可以提振总需求。降低利率和增加货币供给会鼓励借贷和投资。

To tackle structural unemployment, supply-side policies are needed. These include improving education and training, subsidising retraining programmes, and making the labour market more flexible. Governments can also invest in infrastructure to improve geographical mobility.

应对结构性失业需要供给侧政策，包括改善教育和培训、资助再培训项目，以及提高劳动力市场灵活性。政府还可以投资基础设施以改善地理流动性。

Reducing frictional unemployment involves improving the flow of job information. Job centres, online job boards, and career counselling services can help job seekers match with vacancies more quickly. Some governments offer hiring subsidies to encourage firms to take on new workers.

减少摩擦性失业涉及改善职位信息流动。就业中心、在线招聘板和职业咨询服务能够帮助求职者更快匹配空缺岗位。一些政府提供招聘补贴，鼓励企业雇佣新员工。

11. The Natural Rate of Unemployment | 自然失业率

The natural rate of unemployment (NRU) is the rate that exists when the economy is at full capacity, with no cyclical unemployment. It consists of frictional, structural, and seasonal unemployment. At the NRU, the economy is operating on its PPC.

自然失业率是指经济处于充分产能、不存在周期性失业时的失业率。它包含摩擦性、结构性和季节性失业。在自然失业率下，经济处于生产可能性曲线上运行。

The NRU is not zero because there will always be some workers in transition and some skills mismatches. When the actual unemployment rate equals the NRU, the economy is said to be at full employment.

自然失业率并不为零，因为总会有一些工人处于转换过程中，总会存在技能不匹配。当实际失业率等于自然失业率时，可以说经济处于充分就业状态。

12. Unemployment and the Phillips Curve | 失业与菲利普斯曲线

The Phillips curve shows an inverse relationship between inflation and unemployment in the short run. As unemployment falls, inflation tends to rise, and vice versa. This trade-off is a common topic in IGCSE Economics, especially when evaluating policy choices.

菲利普斯曲线显示了短期通货膨胀与失业之间的反向关系。当失业下降时，通胀往往会上升，反之亦然。这种取舍关系是 IGCSE 经济中的常见话题，特别在评估政策选择时。

In the long run, however, many economists believe that unemployment returns to the natural rate regardless of inflation. This is shown by a vertical long-run Phillips curve at the NRU. It implies that expansionary policies cannot permanently lower unemployment without causing accelerating inflation.

然而，长期中许多经济学家认为，无论通胀如何，失业率会回归自然失业率。这体现为一条位于自然失业率处的垂直长期菲利普斯曲线。它意味着扩张性政策无法永久压低失业率而不引发加速通胀。

Understanding this helps you evaluate government policies: a short-term boost to employment may come at the cost of higher prices, a concept you may need to discuss in 6-mark or 8-mark evaluation questions.

理解这一点有助于你评估政府政策：短期内提升就业可能会以物价上涨为代价，你或许需要在 6 分或 8 分的评估题中讨论这一概念。
