📚 IGCSE Economics: Trade Unions Key Points | IGCSE 经济：工会考点精讲

A trade union is an organized association of workers formed to protect and advance their common interests. In IGCSE Economics, you need to understand how unions influence labour markets, wage determination, and employment levels. This article covers every essential concept, diagram, and evaluation point you will encounter in your exam.

工会是由工人组成的、为保护和促进其共同利益而组织起来的团体。在 IGCSE 经济中，你需要理解工会如何影响劳动力市场、工资决定和就业水平。本文将涵盖考试中会遇到的每一个核心概念、图表和评估要点。

1. What are Trade Unions? | 什么是工会？

A trade union is a formal group of employees who join together to negotiate with employers over pay, working conditions, hours, and other aspects of employment. The main goal is collective representation: a single worker may have little bargaining power, but a united group can exert significant pressure on an employer. Trade unions are a type of pressure group and are most common in industries with large numbers of employees.

工会是雇员组成的正式团体，他们联合起来就工资、工作条件、工时和其他就业方面的议题与雇主进行谈判。其核心目标是集体代表：单个工人的议价能力可能很小，但联合起来的群体却能对雇主施加巨大压力。工会是一种压力团体，在拥有大量雇员的行业中最为普遍。

Unions can operate at the level of a single company, across an entire industry, or across the whole economy as general unions. They are funded by membership subscriptions and are often led by elected officials. In many countries, workers have the legal right to join a trade union, though the extent of legal protection varies.

工会可以在单个公司、整个行业或整体经济（综合工会）的层面上运作。它们的资金来自会员缴纳的会费，通常由选举产生的官员领导。在许多国家，工人有加入工会的合法权利，尽管法律保护的范围各不相同。

2. Types of Trade Unions | 工会的类型

Trade unions are often classified by the type of members they represent. Understanding these categories helps you explain why some unions are more powerful than others.

工会通常根据其代表的会员类型进行分类。理解这些类别有助于你解释为什么某些工会比其他的更强大。

Craft unions represent workers with a particular skill or trade, such as electricians or carpenters. These unions tend to have strong bargaining power because their members possess scarce, specific skills that are hard for employers to replace quickly.

职业工会 代表具有特定技能或手艺的工人，例如电工或木匠。这类工会通常有很强的议价能力，因为其成员拥有稀缺的、雇主难以迅速替代的专业技能。

Industrial unions organize all workers in a given industry regardless of their particular job role, for example, all workers in the railway industry. This broad membership base can make strikes highly disruptive, increasing union influence.

产业工会 将某一特定产业中的所有工人组织起来，不论其具体岗位，例如铁路行业的所有工人。这种广泛的会员基础可以使罢工极具破坏性，从而增强工会的影响力。

General unions accept workers from many different industries and occupations. They are often large in membership numbers but may have less focused bargaining power. White-collar unions represent professional and administrative workers, such as teachers, nurses, or civil servants.

综合工会 接受来自许多不同行业和职业的工人。它们的会员数量通常很大，但议价能力可能不够集中。白领工会 代表专业和行政工作者，如教师、护士或公务员。

3. Objectives of Trade Unions | 工会的目标

The primary objectives of trade unions revolve around improving the economic and non-economic welfare of their members. While specific goals vary, exam questions often expect you to list the key aims.

工会的主要目标围绕改善其成员的经济和非经济福利。虽然具体目标各不相同，但试题通常期望你列出关键目标。

Wage maximisation or improvement is the most obvious goal: unions aim to push wages above the free-market equilibrium level. They also negotiate for better working conditions, including safety standards, reasonable working hours, and paid holidays.

工资最大化或提高工资是最明显的目标：工会力求将工资推到自由市场均衡水平以上。他们还会为改善工作条件进行谈判，包括安全标准、合理的工作时间和带薪假期。

Job security is another crucial objective. Unions seek to protect members from arbitrary dismissal and ensure that employers follow fair redundancy procedures when jobs must be cut. Many unions also provide legal support and training opportunities for members, and they lobby governments for legislation that benefits workers, such as minimum wage laws or health and safety regulations.

工作保障是另一个关键目标。工会力求保护成员不受任意解雇，并确保雇主在必须裁员时遵循公平的裁员程序。许多工会还为其成员提供法律支持和培训机会，并游说政府通过有利于工人的立法，如最低工资法或健康与安全法规。

4. Collective Bargaining | 集体谈判

Collective bargaining is the process by which trade unions negotiate with employers or employer associations on behalf of a group of workers. It is the central mechanism through which unions achieve their objectives. Instead of each worker negotiating individually, the union bargains collectively over wages, working time, and other conditions.

集体谈判是工会代表一群工人与雇主或雇主协会进行协商的过程。这是工会实现其目标的核心机制。工会不是由每个工人单独谈判，而是就工资、工时和其他条件进行集体议价。

Collective bargaining can take place at different levels: single-employer bargaining occurs when a union negotiates with one company; multi-employer bargaining involves a union negotiating with several firms in the same industry simultaneously. The outcome of collective bargaining is often a formal, legally enforceable agreement.

集体谈判可以在不同层面进行：单个雇主谈判指工会与一家公司进行协商；多雇主谈判则指工会与同一行业中的多家公司同时进行协商。集体谈判的结果往往是一份正式的、具有法律强制执行力的协议。

If the two sides cannot agree, there may be a breakdown in negotiations. This can lead to industrial action such as a strike or a work-to-rule. The threat of such action gives unions bargaining power, but its effectiveness depends on factors like the level of union membership and the availability of substitute labour.

如果双方无法达成一致，谈判可能会破裂。这可能导致产业行动，如罢工或怠工。此类行动的威胁赋予了工会议价能力，但其有效性取决于工会会员比例和替代劳动力的可获得性等因素。

5. Industrial Action | 产业行动

Industrial action refers to measures taken by workers, usually organized by their union, to put pressure on an employer during a dispute. The most well-known form is a strike, where workers collectively refuse to work, withdrawing their labour. Strikes can be official (sanctioned by the union with a proper ballot) or unofficial (wildcat strikes without union backing).

产业行动指工人（通常由工会组织）在争端期间为给雇主施加压力而采取的措施。最广为人知的形式是罢工，即工人集体拒绝工作，撤回自己的劳动力。罢工可以是官方的（经工会批准并经过正式投票），也可以是非官方的（未经工会支持的野猫式罢工）。

Other forms of industrial action include a work-to-rule, where employees strictly follow every rule and procedure, causing production to slow down dramatically. An overtime ban is another tactic: workers refuse to work beyond their contracted hours, reducing output and flexibility for the employer.

其他形式的产业行动包括怠工（按章工作），即员工严格执行每一条规则和程序，导致生产大幅放缓。禁令加班是另一种策略：工人拒绝在合同时间外工作，从而减少雇主的产出和灵活性。

Industrial action imposes costs on both sides. Workers lose wages during a strike, while firms lose revenue and may damage customer relationships. That is why both parties generally prefer to reach a negotiated settlement without resorting to a strike.

产业行动给双方都带来成本。工人在罢工期间失去工资，而企业则损失收入并可能损害客户关系。这就是为什么双方通常更愿意在不诉诸罢工的情况下通过谈判达成和解的原因。

6. Impact on Wages and Employment in a Perfectly Competitive Labour Market | 在完全竞争劳动力市场中对工资和就业的影响

In a perfectly competitive labour market, wages and employment are determined by the intersection of the demand for labour (DL) and the supply of labour (SL). The demand curve represents the marginal revenue product of labour, while the supply curve shows the number of workers willing to work at each wage rate.

在完全竞争的劳动力市场中，工资和就业由劳动力需求（DL）与劳动力供给（SL）的交点决定。需求曲线代表劳动力的边际收益产品，而供给曲线表示在每个工资水平下愿意工作的工人数量。

When a trade union successfully pushes the wage above the equilibrium level, say from W₀ to W₁, the market no longer clears. At the higher wage, the quantity of labour demanded by firms falls (from Q₀ to Q₁), while the quantity of labour supplied by workers rises (from Q₀ to Q₂). This creates a surplus of labour – classical unemployment – equal to Q₂ − Q₁.

当工会成功地将工资推到均衡水平以上时，比如从W₀提高到W₁，市场就不再出清。在更高的工资水平下，企业所需的劳动力数量下降（从Q₀降至Q₁），而工人愿意提供的劳动力数量增加（从Q₀增至Q₂）。这就产生了劳动力过剩——即古典失业——数量为Q₂ − Q₁。

This analysis suggests a clear trade-off: higher union wages can lead to lower employment in that sector, assuming the labour market is competitive. In an exam, you should be able to draw and explain a diagram showing the wage floor imposed by a union and the resulting unemployment.

这一分析表明一个清晰的权衡：假设劳动力市场是竞争的，更高的工会工资会导致该部门的就业下降。在考试中，你应该能够画出并解释显示工会设定的工资下限及由此产生的失业的图表。

7. Impact in a Monopsony Labour Market | 在买方垄断劳动力市场中的影响

A monopsony is a labour market structure where there is a single dominant employer, or a very small number of employers, giving the employer significant wage-setting power. In a monopsony, the employer faces the market supply curve of labour and the marginal cost of labour (MCL) curve lies above it.

买方垄断是一种劳动力市场结构，其中有一个占主导地位的雇主，或极少数雇主，从而赋予雇主巨大的工资决定权。在买方垄断中，雇主面临市场劳动力供给曲线，而劳动力边际成本（MCL）曲线位于其上方。

A profit-maximising monopsonist employs workers where MCL equals marginal revenue product (MRP), at employment level Q₀, and pays the lowest wage necessary to attract that number, W₀, which lies on the supply curve. This results in a lower wage and lower employment than under perfect competition.

一个追求利润最大化的买方垄断雇主会在MCL等于边际收益产品（MRP）处雇佣工人，即雇佣水平Q₀，并支付吸引这一数量所需的最低工资W₀，该工资落在供给曲线上。这导致了比完全竞争条件下更低的工资和更低的就业水平。

If a trade union enters a monopsonistic market, it can negotiate a wage increase up to a certain level without causing unemployment. For example, a union-imposed wage of W₁ between W₀ and the competitive equilibrium can actually increase employment as well as wages, because it effectively flattens the MCL curve over that range. This is a key evaluation point: unions are not always harmful to employment; in monopsony they can correct market failure.

如果工会进入买方垄断市场，它可以将工资谈判提高到某一水平，而不引起失业。例如，工会设定的处在W₀和竞争性均衡之间的工资W₁实际上可以同时提高就业和工资，因为它在该范围内有效地拉平了MCL曲线。这是一个关键的评估点：工会并非总是对就业有害；在买方垄断中，它们可以纠正市场失灵。

8. Factors Affecting Trade Union Power | 影响工会权力的因素

The bargaining power of a trade union is not fixed. Several factors determine whether a union can successfully raise wages and protect jobs without causing significant unemployment.

工会的议价能力并非固定不变。有几个因素决定了一个工会能否在成功提升工资和保护工作的同时，不引起严重的失业。

Union density, the proportion of workers in a firm or industry who are union members, is critical. A high density means the union represents most workers, making collective action more credible and a strike more damaging to the employer.

工会密度，即企业或行业中工会会员的比例，是关键因素。高密度意味着工会代表了大多数工人，使得集体行动更可信，罢工对雇主的打击更大。

Elasticity of demand for the product: if the product made by unionised workers has price-inelastic demand, the employer can more easily pass on higher wage costs to consumers through higher prices without a large fall in sales. This reduces the risk of job losses. Similarly, the elasticity of demand for labour matters; if it is easy to substitute capital for labour, union power is weakened.

产品需求弹性：如果工会工人制造的产品需求缺乏价格弹性，雇主就更容易通过提高价格将增加的工资成本转嫁给消费者，而不会导致销量大幅下降。这就降低了失业的风险。同理，劳动力需求弹性也很重要；如果资本很容易替代劳动，工会的力量就会被削弱。

Legal and government support can strengthen or weaken unions. Laws that protect the right to strike and require employers to recognise unions increase power; legislation restricting picketing or requiring high ballot thresholds for strike action reduces it. The economic climate also matters: in a recession with high unemployment, workers may be less willing to strike for fear of losing their jobs.

法律和政府支持可以增强或削弱工会。保护罢工权和要求雇主承认工会的法律能增强其权力；限制纠察队活动或要求通过高门槛投票才能罢工的立法则会降低权力。经济形势也很重要：在高失业率的衰退期，工人可能因害怕失业而不太愿意罢工。

9. Advantages of Trade Unions | 工会的优点

Trade unions can bring a range of economic and social benefits, not only to their members but sometimes to the wider economy. Examiners expect you to be able to discuss both the strengths and limitations of unions.

工会可以带来一系列经济和社会效益，不仅是对其成员，有时对更广泛的经济也是如此。考官希望你能讨论工会的长处和局限性。

Unions can combat exploitative practices by monopsony employers, pushing wages closer to a competitive level without necessarily causing job losses. They provide a voice for workers, improving communication between management and staff, which can raise morale and productivity. This is known as the ‘collective voice’ effect.

工会可以对抗买方垄断雇主的剥削性做法，将工资推向更接近竞争水平，而不一定导致失业。它们为工人提供了发声渠道，改善了管理层与员工之间的沟通，从而可以提高士气和生产率。这被称为”集体发声”效应。

By standardising wages and conditions across firms, unions can reduce wage inequality within an industry. They also promote non-wage improvements such as safer workplaces and better training, which can reduce staff turnover and lower recruitment costs for firms in the long run.

通过在企业间统一工资和条件，工会可以减少行业内的工资不平等。它们还推动非工资方面的改善，如更安全的工作场所和更好的培训，从长远来看可以降低员工流失率，减少企业的招聘成本。

Advantage	Explanation
Countervailing power to employers	Balances the power of large firms, especially in monopsony.
Collective voice	Improves communication and productivity.
Reduced inequality	Standardises pay scales across workers.
Safer workplaces	Campaigns for health and safety improvements.

10. Disadvantages of Trade Unions | 工会的缺点

Critics argue that trade unions can create inefficiencies and damage the wider economy. The most common criticism in IGCSE exams is that union wage-setting can cause unemployment and reduce a firm’s international competitiveness.

批评者认为，工会可能造成低效率并损害更广泛的经济。IGCSE 考试中最常见的批评是，工会制定的工资水平会导致失业并降低企业的国际竞争力。

As explained earlier, pushing wages above the competitive equilibrium in a normal labour market creates a surplus of labour – structural unemployment. Higher labour costs may also cause firms to raise prices, fuelling cost-push inflation. In some cases, firms may be forced to cut investment or relocate production overseas to countries with weaker unions and lower wages.

如前所述，在正常的劳动力市场中，将工资推到竞争均衡之上会造成劳动力过剩——结构性失业。更高的劳动力成本也可能导致企业提高价格，加剧成本推动型通货膨胀。在某些情况下，企业可能被迫削减投资或将生产转移到海外工会力量较弱、工资较低的国家。

Unions that protect inefficient working practices, such as demarcation rules that restrict which workers can do specific tasks, slow down productivity improvements. Furthermore, frequent strike action can disrupt essential services and damage the economy, and the existence of a union may also create an adversarial culture between workers and management rather than a cooperative one.

保护低效工作做法的工会（如限制哪些工人可以从事特定任务的岗位划分规则）会拖慢生产率的提高。此外，频繁的罢工行动可能扰乱基本服务并损害经济，而工会的存在也可能在工人与管理层之间制造对抗性文化，而不是合作文化。

Disadvantage	Explanation
Classical unemployment	Wages above equilibrium reduce employment.
Cost-push inflation	Rising labour costs passed on to consumers.
Loss of competitiveness	Higher costs reduce exports and attract imports.
Restrictive practices	Reduces flexibility and slows innovation.

工会缺点总结

11. Recent Trends in Trade Union Membership | 工会会员数量的近期趋势

In many developed economies, trade union membership has declined significantly over the last several decades. In the UK, for example, union density fell from over 50% in the late 1970s to around 23% today. This trend is a popular exam context, often linked to structural changes in the economy.

在许多发达经济体，近几十年来工会会员数量显著下降。例如，在英国，工会密度从1970年代末的超过50%下降到如今的约23%。这一趋势是常见的考试背景，通常与经济的结构性变化相关联。

One reason is the decline of traditional manufacturing industries, such as coal mining and steel production, where unions were historically very strong. Employment has shifted towards the service sector, where workers are often in smaller workplaces and have been harder to organise. The rise of part-time, temporary, and gig-economy work also makes union membership less attractive and harder to maintain.

一个原因是传统制造业（如煤炭开采和钢铁生产）的衰落，而这些行业历史上工会势力非常强大。就业岗位已转向服务业，这些行业的工人往往在较小的工作场所中，更难组织起来。兼职、临时和零工经济的兴起也使得工会会员资格吸引力下降，且更难维持。

Changes in government legislation have also affected union power. In the 1980s, UK legislation restricted secondary picketing, enforced secret ballots before strikes, and limited the closed shop (where union membership was compulsory to get a job). Similar trends occurred in many countries. However, in some emerging economies and public-sector occupations, union membership remains relatively high.

政府立法的变化也影响了工会的力量。1980年代，英国的立法限制了辅助纠察队，要求在罢工前进行无记名投票，并限制了封闭式雇佣制度（即必须加入工会才能获得工作）。许多国家也出现过类似的趋势。然而，在一些新兴经济体和公共部门职业中，工会会员比例仍然相对较高。

12. Evaluation of Trade Unions | 对工会的评价

When writing exam answers about trade unions, you must show evaluation. This means looking beyond a simple ‘good or bad’ judgement and considering circumstances and different viewpoints.

在书写关于工会的考试答案时，你必须展现出评估能力。这意味着不能仅做出简单的”好或坏”的判断，还要考虑具体情境和不同观点。

The impact of a union depends heavily on the market structure. In a perfectly competitive labour market, a union-driven wage rise is likely to cause some unemployment. But in a monopsony, it can increase both wages and employment, improving allocative efficiency. So you cannot say unions always reduce employment.

工会的影响很大程度上取决于市场结构。在完全竞争的劳动力市场中，工会推动的工资上涨很可能导致一定的失业。但在买方垄断市场中，它可以同时增加工资和就业，提高配置效率。因此你不能说工会总是会减少就业。

The extent of union power matters too. A relatively weak union with low density and limited legal protection will not achieve large wage gains, whereas a strong union in an essential industry with inelastic demand can push wages up substantially. The time period is also important: the short-run effects of a strike can be disruptive, but in the long run, unions may contribute to a more stable, motivated, and productive workforce.

工会力量的大小也很重要。一个会员密度低、法律保护有限的相对弱小的工会将无法实现大幅度的工资增长，而一个在需求缺乏弹性的关键行业中强大的工会则可以大幅推高工资。时间周期也很重要：罢工的短期影响可能具有破坏性，但从长远来看，工会可能有助于形成一支更稳定、更有动力和更有生产力的劳动力队伍。

Finally, consider external factors like globalisation. Increased competition from overseas producers reduces the ability of unions to push up wages without cost ng their members’ jobs, because employers can more credibly threaten to relocate or substitute capital for labour. A balanced conclusion will recognise that unions have the potential to both benefit and harm workers and the economy, and the outcome depends on the specific conditions in each case.

最后，还需考虑外部因素，如全球化。来自海外生产商日益加剧的竞争削弱了工会推高工资而不使其成员失去工作的能力，因为雇主可以更可信地威胁要将生产转移或使用资本替代劳动力。一个平衡的结论应当认识到，工会有可能既造福又损害工人和经济，具体结果取决于每种情况下的具体条件。
