📚 Labour Productivity: Measurement, Determinants and Economic Impact | 劳动生产率：衡量、决定因素与经济影响
Labour productivity is the key supply-side indicator that connects the effort and skill of workers to the performance of the whole economy. For Cambridge A Level Economics, it is important to distinguish between output per worker and output per hour, explain the main determinants, and evaluate the consequences for costs, competitiveness and living standards.
劳动生产率是连接工人努力和技能与整个经济表现的关键供给侧指标。对于剑桥 A Level 经济学，重要的是区分人均产出和每小时产出，解释主要决定因素，并评价其对成本、竞争力和生活水平的影响。
1. Defining Labour Productivity | 劳动生产率定义
Labour productivity measures how efficiently labour is converted into output. It is normally defined as total output divided by the quantity of labour input.
劳动生产率衡量劳动转化为产出的效率。它通常定义为总产出除以劳动投入的数量。
Labour productivity = Total output ÷ Labour input (workers or hours)
劳动生产率 = 总产出 ÷ 劳动投入（工人数或小时数）
When productivity rises, an economy can produce more goods and services from a given labour force. This shifts the long-run aggregate supply curve to the right and raises potential GDP.
当生产率提高时，一个经济体可以用给定的劳动力生产更多商品和服务。这会使长期总供给曲线向右移动，并提高潜在 GDP。
2. Measuring Labour Productivity | 衡量劳动生产率
The most common measures are output per worker and output per hour worked. Both should be calculated using real output to remove the effects of inflation.
最常用的衡量指标是人均产出和每小时产出。两者都应使用实际产出来计算，以剔除通货膨胀的影响。
Output per worker = Real GDP ÷ Total employed persons
人均产出 = 实际 GDP ÷ 就业总人数
Output per hour is often regarded as a more accurate measure of efficiency because it adjusts for differences in working time. An economy may show high output per worker simply because workers work very long hours, not because they are productive.
每小时产出通常被认为是更准确的效率衡量方法，因为它调整了工作时间的差异。一个经济体可能仅仅因为工人工作时间很长而显示出较高的人均产出，而不是因为工人生产效率高。
3. Output per Worker vs Output per Hour | 人均产出与每小时产出
Output per worker is easier to calculate and is widely used in international comparisons. However, it can be distorted by changes in part-time employment, overtime and average hours worked.
人均产出更容易计算，广泛用于国际比较。但它可能被兼职就业、加班和平均工作时间的变化所扭曲。
Output per hour isolates the true productive efficiency of each hour of work. For example, if an economy shifts towards part-time jobs, output per worker may fall even though hourly productivity remains unchanged. This distinction matters for policy design.
每小时产出分离出每个小时工作的真实生产效率。例如，如果一个经济体转向兼职工作，人均产出可能下降，即使每小时生产率保持不变。这一区别对政策设计很重要。
4. The Productivity Gap | 生产率差距
The productivity gap is the difference between a country’s labour productivity and that of leading comparator economies. For the UK, the gap with the United States, Germany and France has been a central policy concern.
生产率差距是指一国劳动生产率与领先对比经济体之间的差异。对英国而言，与美国、德国和法国的差距一直是政策关注的焦点。
The gap suggests that output per hour is lower than it could be. Possible causes include weaker capital investment, lower R&D spending, skills shortages, poor management quality and planning restrictions. Closing the gap would raise potential growth without inflationary pressure.
这一差距表明每小时产出低于可能达到的水平。可能的原因包括资本投资较弱、研发支出较低、技能短缺、管理质量较差以及规划限制。缩小差距将在没有通胀压力的情况下提高潜在增长。
5. Determinants: Human Capital | 决定因素：人力资本
Human capital is the stock of skills, knowledge, education and health embodied in workers. Investment in human capital, through schooling, vocational training and healthcare, raises the ability of labour to produce more from given inputs.
人力资本是工人身上蕴含的技能、知识、教育和健康的存量。通过学校教育、职业培训和医疗保健对人力资本进行投资，可以提高劳动力利用给定投入生产更多产出的能力。
Better-educated workers are usually more adaptable to new technology, make fewer errors and require less supervision. This is why education spending is classified as a supply-side policy to raise productivity.
受教育程度更高的工人通常更能适应新技术，出错更少，所需的监督也更少。这就是为什么教育支出被归类为提高生产率的供给侧政策。
6. Determinants: Capital Investment and Technology | 决定因素：资本投资与技术
Capital investment raises labour productivity through capital deepening, which means more or better machinery, equipment, software and infrastructure per worker. Automation and ICT allow a single worker to manage much larger volumes of output.
资本投资通过资本深化提高劳动生产率，资本深化意味着人均拥有更多或更好的机器、设备、软件和基础设施。自动化和信息通信技术使单个工人能够管理大得多的产出量。
However, investment alone may not raise productivity if workers lack the skills to use new capital. Capital and labour are complements in many modern production processes, so investment in technology needs to be matched by training.
然而，如果工人缺乏使用新资本的技能，仅靠投资可能不会提高生产率。在许多现代生产过程中，资本和劳动是互补的，因此技术投资需要与培训相匹配。
7. Determinants: Management, Incentives and Work Practices | 决定因素：管理、激励与工作实践
Management quality and work organisation are important non-price determinants of productivity. Better managers set clear targets, monitor performance, reduce waste and adopt best practice methods such as lean production and just-in-time stock control.
管理质量和工作组织是生产率的重要非价格决定因素。优秀的管理者设定明确目标、监控绩效、减少浪费，并采用精益生产和准时库存控制等最佳实践方法。
Incentives also matter. Performance-related pay, profit sharing, employee involvement and flexible working can raise motivation and reduce turnover, leading to higher output per hour. Poor industrial relations can have the opposite effect.
激励也很重要。绩效工资、利润分享、员工参与和灵活工作安排可以提高积极性并减少人员流动，从而提高每小时产出。糟糕的劳资关系则会产生相反效果。
8. Productivity and Costs | 生产率与成本
Labour productivity directly affects unit labour costs (ULC), which measure labour cost per unit of output. The relationship is:
劳动生产率直接影响单位劳动成本（ULC），单位劳动成本衡量每单位产出的劳动成本。其关系为：
Unit labour cost = Wage rate ÷ Labour productivity
单位劳动成本 = 工资率 ÷ 劳动生产率
If wages rise by 3% but productivity also rises by 3%, unit labour costs remain unchanged and there is no cost-push pressure on prices. If wages rise faster than productivity, unit labour costs increase, which may reduce profit margins or force firms to raise prices.
如果工资上涨 3%，但生产率也提高 3%，单位劳动成本不变，就不会对价格产生成本推动压力。如果工资上涨快于生产率，单位劳动成本就会上升，这可能会压缩利润率或迫使企业提高价格。
This link explains why central banks and governments monitor productivity growth closely: sustained productivity growth allows real wages to rise without inflation.
这一联系解释了为什么中央银行和政府密切关注生产率增长：持续的生产率增长允许实际工资上涨而不引发通胀。
9. Productivity, Competitiveness and Living Standards | 生产率、竞争力与生活水平
Higher labour productivity lowers unit costs, which improves price competitiveness in export markets. Domestic firms can either reduce prices to gain market share or maintain prices and enjoy higher margins.
较高的劳动生产率降低单位成本，从而提高了在出口市场上的价格竞争力。国内企业要么降低价格以获得市场份额，要么维持价格并享受更高的利润率。
In the long run, productivity growth is the main source of rising real wages and living standards. It increases potential GDP and shifts the production possibility frontier outward, enabling more goods and services per person.
从长期看，生产率增长是实际工资和生活水平提高的主要来源。它增加了潜在 GDP，使生产可能性边界向外移动，从而使人均商品和服务增加。
10. Short-Run vs Long-Run Productivity | 短期与长期生产率
Measured productivity often moves with the business cycle in the short run. During a recession, output may fall faster than employment because firms hoard labour, expecting a recovery. This causes measured productivity to fall temporarily.
短期内，衡量到的生产率通常随经济周期波动。在经济衰退期间，产出下降可能快于就业，因为企业预期复苏而囤积劳动力。这会导致衡量到的生产率暂时下降。
In a recovery, firms can raise output using existing staff before hiring new workers, so productivity rises quickly. Long-run productivity trends are driven by structural factors such as investment, skills and technology, not by cyclical swings.
在复苏阶段，企业可以在招聘新工人之前利用现有员工提高产出，因此生产率迅速上升。长期生产率趋势由投资、技能和技术等结构性因素驱动，而不是由周期性波动驱动。
11. Supply-Side Policies to Raise Productivity | 提高生产率的供给侧政策
Governments can use supply-side policies to raise labour productivity. Spending on education and training improves human capital; tax allowances for investment and R&D encourage capital deepening and innovation.
政府可以利用供给侧政策提高劳动生产率。教育和培训支出改善人力资本；投资和研发税收减免鼓励资本深化和创新。
Infrastructure projects reduce transport costs and delays, competition policy forces firms to become more efficient, and labour market reforms can make hiring and working practices more flexible. However, many of these policies involve long time lags and high fiscal costs.
基础设施项目降低运输成本和延误，竞争政策迫使企业提高效率，劳动力市场改革可以使雇佣和工作实践更加灵活。但许多这类政策涉及较长的时间滞后和较高的财政成本。
