📚 Labour Market IGCSE Economics | IGCSE 经济 劳动力市场 考点精讲
For IGCSE Economics, understanding the labour market is fundamental. It involves the interaction of workers (households) and employers (firms) to determine how many people are hired and at what wage. This article breaks down the core concepts, models, and impacts needed for CIE examinations.
在IGCSE经济中，理解劳动力市场是基础。它涉及劳动者（家庭）与雇主（企业）之间的相互作用，决定雇佣多少人以及支付多少工资。本文分解了CIE考试所需的核心概念、模型和影响。
1. What is the Labour Market? | 什么是劳动力市场？
The labour market is where individuals seeking work (supply of labour) meet employers who want to hire workers (demand for labour). The ‘price’ determined is the wage rate. It is a factor market because labour is one of the four factors of production.
劳动力市场是求职者（劳动力供给）与需要雇佣工人的雇主（劳动力需求）相遇的地方。确定的“价格”就是工资率。它是一个生产要素市场，因为劳动力是生产的四大要素之一。
Key terms include: labour force (all people available for work), employed and unemployed. The wage rate is usually expressed as a certain amount per hour or per month. Unlike goods markets, labour is not a homogeneous product; each worker has different skills and motivations.
关键术语包括：劳动力（所有可以工作的人）、就业者和失业者。工资率通常表示为每小时或每月的金额。与商品市场不同，劳动力不是同质产品；每个工人拥有不同的技能和动机。
2. Demand for Labour | 劳动力需求
Demand for labour is the number of workers that firms are willing and able to hire at different wage rates in a given period, ceteris paribus. There is an inverse relationship between the wage rate and the quantity of labour demanded: as wages rise, firms tend to hire fewer workers because labour becomes more expensive.
劳动力需求是指在其他条件不变的情况下，企业在一定时期内愿意且能够以不同工资率雇佣的工人数量。工资率与劳动力需求量之间存在反向关系：当工资上升时，企业往往雇佣更少的工人，因为劳动力成本增加。
Diagrammatically, the demand curve for labour slopes downwards. A movement along the curve is caused by a change in the wage rate (extension or contraction of demand). A shift of the entire curve is caused by factors other than the wage rate.
从图形上看，劳动力需求曲线向下倾斜。沿曲线的移动是由工资率的变化引起的（需求量的扩展或收缩）。整条曲线的平移是由工资率以外的因素引起的。
3. Derived Demand | 派生需求
Labour demand is a derived demand, meaning it depends on the demand for the goods and services that labour helps to produce. If consumer demand for smartphones increases, the demand for workers in smartphone factories will also rise. Conversely, a fall in product demand reduces the demand for labour.
劳动力需求是一种派生需求，意味着它取决于对劳动力所帮助生产的商品和服务的需求。如果消费者对智能手机的需求增加，那么智能手机工厂对工人的需求也会增加。相反，产品需求下降会减少对劳动力的需求。
This principle helps explain why workers in booming industries see growing job opportunities, while those in declining sectors face redundancy. The concept of derived demand also applies to other factors like capital; both are demanded not for their own sake, but for what they produce.
这一原理有助于解释为什么繁荣行业的工人看到就业机会增长，而衰退行业的工人面临裁员。派生需求的概念也适用于资本等其他要素；对它们的需求不是为了自身，而是因为它们能生产的产品。
4. Supply of Labour | 劳动力供给
Supply of labour is the number of workers willing and able to offer their services at different wage rates in a given time period. For an individual worker, higher wages usually encourage more hours worked (the substitution effect). However, at very high wages, workers may choose to work fewer hours to enjoy more leisure time (the income effect).
劳动力供给是指在特定时期内愿意且能够以不同工资率提供服务的工人数量。对于单个工人来说，较高的工资通常会鼓励更多的工作时间（替代效应）。然而，在工资非常高的情况下，工人可能会选择减少工作时间，享受更多的休闲时间（收入效应）。
The market supply curve for labour generally slopes upwards, indicating that more people will wish to join a particular labour market when wages are higher. The supply of labour to a specific occupation depends on both monetary and non-monetary considerations.
劳动力市场供给曲线通常向上倾斜，表明当工资更高时，会有更多人希望进入特定的劳动力市场。特定职业的劳动力供给取决于金钱和非金钱两方面的考量。
5. Factors Affecting Labour Supply | 影响劳动力供给的因素
Factors that shift the supply curve of labour include: changes in the size of the population (more working-age people increase supply), migration (inward migration boosts supply), changes in income tax and benefits, barriers to entry such as qualifications required, and non-wage factors like job satisfaction and working conditions.
移动劳动力供给曲线的因素包括：人口规模的变化（适龄劳动人口增加则供给增加），移民（迁入移民增加供给），所得税和福利金的变化，进入壁垒如所需的资格，以及非工资因素如工作满意度和工作条件。
Education and training plays a vital role. If a career requires many years of education, the supply of workers will be relatively lower in the short run. Similarly, higher income taxes may reduce the incentive to work, shifting the supply curve to the left.
教育和培训起着至关重要的作用。如果某个职业需要多年的教育，短期内劳动力供给相对较低。同样，较高的所得税可能会降低工作激励，使供给曲线向左移动。
6. Wage Determination | 工资决定
The equilibrium wage rate is determined by the intersection of labour demand and labour supply curves. At this point, the quantity of labour demanded by firms equals the quantity of labour supplied by workers. There is no excess supply (unemployment) or excess demand (labour shortage) at equilibrium.
均衡工资率由劳动力需求曲线和劳动供给曲线的交点决定。在这一点上，企业需求的劳动力数量等于工人供给的劳动力数量。均衡时没有超额供给（失业）或超额需求（劳动力短缺）。
If the wage rate is set above equilibrium, such as by a trade union or government, the quantity supplied will exceed the quantity demanded, creating surplus labour (classical unemployment). If the wage is below equilibrium, a shortage of workers will emerge.
如果工资率设定在均衡水平以上，例如由工会或政府设定，供给量将超过需求量，造成劳动力过剩（古典失业）。如果工资低于均衡水平，将出现工人短缺。
7. Wage Differentials | 工资差异
Wage differentials are the differences in wages between different occupations, industries, regions, or workers with different skills. They arise because labour markets are not perfectly competitive and because workers are heterogeneous. Some jobs pay more because they require scarce skills or involve unpleasant conditions.
工资差异是指不同职业、行业、地区或具有不同技能的工人之间的工资差异。它们出现是因为劳动力市场不是完全竞争的，而且工人是异质的。有些工作薪酬更高，因为它们需要稀缺的技能或涉及不愉快的工作条件。
Main reasons for wage differentials include: differences in productivity (more productive workers command higher pay), human capital (education and experience), compensating wage differentials for dangerous or unpleasant jobs, trade union power, and geographical immobility of labour.
工资差异的主要原因包括：生产率的差异（更高效的工人获得更高薪酬），人力资本（教育和经验），对危险或不愉快工作的补偿性工资差异，工会力量，以及劳动力的地理不流动性。
8. Changes in Labour Demand and Supply | 劳动力需求和供给的变化
Several factors can shift the demand for labour curve: changes in product demand, changes in the productivity of labour, advances in technology (which might substitute or complement labour), price of other factors (such as cheaper machinery replacing workers), and government employment regulations.
有几个因素可以移动劳动力需求曲线：产品需求的变化，劳动生产率的提高，技术进步（可能替代或补充劳动力），其他要素的价格（如更便宜的机器替代工人），以及政府的就业法规。
On the supply side, shifts occur due to demographic changes, migration, changes in income and substitution effects across different jobs, and changes in alternative opportunities. For accurate exam analysis, students should be able to illustrate and explain how a shift affects equilibrium wage and employment level.
在供给方面，移动是由于人口变化、移民、不同工作间的收入效应和替代效应变化，以及替代机会的改变。为了准确应考分析，学生应能图示并解释移动如何影响均衡工资和就业水平。
9. Government Intervention: Minimum Wage | 政府干预：最低工资
A minimum wage is a legally imposed price floor in the labour market, setting the lowest hourly wage that employers can pay. It is designed to help low-paid workers and reduce poverty. The impact depends on where the minimum wage is set relative to the equilibrium wage.
最低工资是劳动力市场中法定强制的价格地板，规定了雇主可以支付的最低小时工资。它旨在帮助低薪工人和减少贫困。其影响取决于最低工资相对于均衡工资的水平。
If set above the market equilibrium, a minimum wage creates a surplus of labour (unemployment) because the quantity supplied of workers increases while firms’ quantity demanded falls. However, if the labour market is monopsonistic (single buyer of labour), a minimum wage can theoretically increase both wages and employment.
如果设定在高于市场均衡水平，最低工资会造成劳动力过剩（失业），因为工人供给量增加而企业的需求量下降。然而，如果劳动力市场是买方垄断的（单一劳动力买家），理论上最低工资可以同时提高工资和就业。
The effectiveness and negative consequences are heavily debated. Critics argue it raises costs for businesses, leading to higher prices or job cuts, while proponents stress it ensures a living wage and stimulates consumption.
其有效性和负面后果存在激烈争论。批评者认为它增加了企业成本，导致价格上涨或裁员，而支持者强调它确保了生活工资并刺激消费。
10. Trade Unions and Wage Bargaining | 工会与工资谈判
Trade unions are organisations that represent the interests of workers. They aim to improve members’ pay, working conditions, and job security through collective bargaining with employers. Their power depends on factors such as membership density, legal framework, and the profitability of the firm.
工会是代表工人利益的组织。它们旨在通过与雇主进行集体谈判，改善成员的薪酬、工作条件和工作保障。它们的力量取决于会员密度、法律框架和企业的盈利能力等因素。
Unions can push wages above equilibrium by restricting labour supply (e.g., closed shops, requiring qualifications), or by using industrial action such as strikes to pressure employers into accepting higher wage offers. A successful union wage claim may increase wages for insiders but reduce employment, with those left out forming a pool of unemployed outside the union.
工会可以通过限制劳动力供给（例如，封闭式企业、要求资格）或使用罢工等工业行动向雇主施压以接受更高的工资报价，从而将工资推至均衡以上。成功的工会工资要求可能会提高内部人的工资，但减少就业，那些被排除在外的人形成工会外部的失业人群。
11. Labour Market Imperfections | 劳动力市场不完善
In reality, labour markets often fail to achieve perfect competition due to information problems, immobility of labour, and market power. Workers may lack information about job vacancies, or firms may not know the true productivity of job applicants.
在现实中，劳动力市场往往由于信息问题、劳动力不流动和市场力量而无法实现完全竞争。工人可能缺乏关于职位空缺的信息，或者企业可能不知道求职者的真实生产率。
Geographical immobility occurs when workers find it difficult to move to areas where jobs are available, due to family ties, housing costs, or lack of information. Occupational immobility refers to the difficulty of switching between different types of jobs because of a lack of transferable skills. Both cause structural unemployment.
地理不流动性发生在工人因家庭关系、住房成本或缺乏信息而难以迁移到有就业机会的地区时。职业不流动性指的是由于缺乏可转移技能而难以在不同工种之间转换。两者都会导致结构性失业。
Firms may hold monopsony power, being the dominant employer in a local area, allowing them to set wages below competitive levels. Discrimination based on gender, ethnicity, or age is also a form of market failure that leads to unjustified wage differentials.
企业可能拥有买方垄断力量，成为当地的主要雇主，从而可以将工资设定在竞争水平之下。基于性别、种族或年龄的歧视也是一种市场失灵形式，导致不合理的工资差异。
12. Conclusion: Labour Market Applications in Exams | 结论：劳动力市场在考试中的应用
Mastering the labour market topic requires students to combine theoretical diagrams with real-world applications. Exam questions frequently ask for analysis of how a specific event—such as a rise in net migration or an increase in the national minimum wage—affects wages and employment levels.
掌握劳动力市场专题要求学生将理论图表与现实世界的应用结合起来。考题经常要求分析某一特定事件——如净移民增加或国家最低工资提高——如何影响工资和就业水平。
Always remember that labour demand is derived. Link your answers to changes in the product market. Use precise terminology like ‘extension in demand for labour’ instead of ‘demand increases’ when referring to a movement along the curve. Be prepared to evaluate government policies by discussing both advantages and disadvantages.
永远记住劳动力需求是派生的。将你的答案与产品市场的变化联系起来。当指沿曲线移动时，使用精确术语如“劳动力需求量的扩展”而不是“需求增加”。准备好通过讨论政府政策的优缺点进行评价。
