📚 Transfer Payments | 转移支付
In macroeconomics and public finance, transfer payments are payments made by the government to individuals without any corresponding contribution to production. Unlike government expenditure on goods and services, transfer payments do not directly absorb real resources or add to GDP through the expenditure approach. Instead, they redistribute income within the economy, acting as a key instrument of fiscal policy and social welfare.
在宏观经济学和公共财政中，转移支付是政府支付给个人的款项，而接受者无需提供相应的生产性贡献。与政府购买商品和服务的支出不同，转移支付不直接吸收实际资源，也不通过支出法计入国内生产总值（GDP）。相反，它们在经济体内部进行收入再分配，是财政政策和社会福利的重要工具。
1. Definition of Transfer Payments | 转移支付的定义
A transfer payment is a one-way flow of money from the government to individuals or other levels of government for which no good, service, or factor of production is received in return at that time. Typical recipients include pensioners, unemployed workers, low-income families, and students. In national income accounting, transfer payments are excluded from government spending (G) precisely because they do not represent new output.
转移支付是政府向个人或其他层级政府进行的单向货币流动，此时政府并没有立即获得商品、服务或生产要素作为回报。典型的接受者包括退休人员、失业者、低收入家庭和学生。在国民收入核算中，转移支付被排除在政府支出（G）之外，正是因为它们不代表新的产出。
2. Types of Transfer Payments | 转移支付的类型
Transfer payments can be broadly divided into monetary welfare benefits and in-kind benefits. Monetary transfers include state pensions, unemployment benefits, child benefits, tax credits, and sickness allowances. In-kind transfers are direct provision of goods and services such as free school meals, housing subsidies, and healthcare services that are not part of government consumption but are treated as transfers to households.
转移支付大致可分为货币福利津贴和实物福利两类。货币转移支付包括国家养老金、失业救济金、儿童福利金、税收抵免和疾病津贴。实物转移支付则指直接提供的商品和服务，如免费校餐、住房补贴和医疗保健服务，这些不属于政府消费，而是被视为对住户的转移。
3. Transfer Payments vs. Government Spending on Goods and Services | 转移支付与政府购买商品和服务支出
It is essential to distinguish between transfer payments and government final consumption expenditure. The latter involves the purchase of labour, equipment, or infrastructure and appears directly in the aggregate demand equation as G. Transfer payments, by contrast, do not enter AD directly; they affect consumption (C) indirectly by raising household disposable income. In the UK, the Department for Work and Pensions budget is dominated by transfer payments, whereas the Ministry of Defence budget largely consists of spending on goods and services.
必须区分转移支付与政府最终消费支出。后者涉及购买劳动力、设备或基础设施，并直接作为 G 出现在总需求方程中。相比之下，转移支付不直接进入总需求，而是通过提高家庭可支配收入间接影响消费（C）。在英国，工作和养老金部预算以转移支付为主，而国防部预算则主要由商品和服务支出构成。
4. Transfer Payments and the Circular Flow | 转移支付与循环流量
In the circular flow of income, transfer payments represent an injection from the government sector into the household sector, offset by taxation, which is a leakage. When the government increases transfer payments, households' disposable income rises, leading to higher consumer spending unless the additional income is entirely saved. This mechanism helps sustain aggregate demand during a recession without directly boosting public sector output.
在收入循环流量中，转移支付代表从政府部门向住户部门的注入，与作为漏出的税收相对应。当政府增加转移支付时，家庭可支配收入上升，除非全部被储蓄，否则会导致消费支出增加。这种机制有助于在经济衰退期间维持总需求，而无需直接提升公共部门的产出。
5. Transfer Payments as Automatic Stabilisers | 转移支付作为自动稳定器
Many transfer payments, particularly unemployment benefits and income-related support, function as automatic stabilisers. During an economic downturn, as unemployment rises, spending on jobless benefits automatically increases without any discretionary action by policymakers. This cushions the fall in disposable income and helps stabilise consumption. Conversely, during a boom, transfer payments decline as fewer people qualify, moderating inflationary pressure.
许多转移支付，尤其是失业救济金和与收入挂钩的补贴，发挥着自动稳定器的作用。在经济下行期，随着失业率上升，失业福利支出会自动增加，无需政策制定者采取任何相机抉择的行动。这缓冲了可支配收入的下降，有助于稳定消费。反之，在经济繁荣期，随着符合条件的人数减少，转移支付下降，从而缓和通胀压力。
6. Impact on Income Distribution and Poverty | 对收入分配和贫困的影响
Transfer payments are a primary tool for reducing income inequality and alleviating poverty. Before transfers and taxes, the market distribution of income can be highly unequal. Progressive tax systems combined with means-tested and universal transfers significantly compress the income distribution. The Gini coefficient is typically much lower after taking into account cash benefits and direct taxes. However, the effectiveness depends on the coverage, generosity, and targeting of the transfer system.
转移支付是减少收入不平等和缓解贫困的主要工具。在进行转移和征税之前，市场收入分配可能高度不平等。累进税制与有针对性的和普惠性的转移支付相结合，可以显著压缩收入分配差距。在计入现金福利和直接税之后，基尼系数通常会大幅降低。然而，其有效性取决于转移支付体系的覆盖面、慷慨程度和目标定位。
7. The Multiplier Effect of Transfer Payments | 转移支付的乘数效应
a multiplier effect through the consumption function. An increase in transfer payments of £ s disposable income by the same amount, but the initial increase in aggregate demand is c×£ is the marginal propensity to consume (MPC). The final impact on GDP can be expressed as:
虽然转移支付不属于 G，但通过消费函数可以产生乘数效应。转移支付增加 £x 百万，使得可支配收入增加相同数额，但总需求的初始增量为 c×£x 百万，其中 c 为边际消费倾向（MPC）。对 GDP 的最终影响可表示为：
ΔY = c × ΔTR × k
where k = 1/(1 − c(1 − t) + m)
where ΔTR is the change in transfer payments, t is the marginal tax rate, and m is the marginal propensity to import. The transfer payment multiplier is smaller than the government spending multiplier because the first round of spending is diluted by saving.
其中 ΔTR 为转移支付变化量，t 为边际税率，m 为边际进口倾向。转移支付乘数小于政府支出乘数，因为第一轮支出被储蓄稀释了一部分。
8. Disincentive Effects and the Welfare Trap | 抑制效应与福利陷阱
A major criticism of transfer payments is the potential disincentive to work. When means-tested benefits are withdrawn as earnings rise, beneficiaries face a high effective marginal tax rate, sometimes exceeding 70% or even 100%. This 'welfare trap' or 'poverty trap' can discourage labour supply, increase dependency, and trap individuals in long-term unemployment. Reforms such as in-work tax credits and universal basic income are debated as ways to reduce these disincentives.
对转移支付的一个主要批评是其可能抑制工作积极性。当收入增加时，基于家计调查的福利会被削减，导致受益人面临很高的有效边际税率，有时超过 70% 甚至 100%。这种“福利陷阱”或“贫困陷阱”可能抑制劳动供给，增加依赖性，使个人陷入长期失业。诸如工作税收抵免和全民基本收入等改革措施被广泛讨论，以期减少这些抑制效应。
9. Evaluation: Efficiency vs. Equity | 评估：效率与公平
Economists evaluate transfer payments through the lens of the equity-efficiency trade-off. On the equity side, transfers reduce poverty and provide a safety net, which can enhance social cohesion and possibly long-run growth by improving health and education. On the efficiency side, high transfers require high taxation, may distort labour-leisure choices, and can reduce incentives for risk-taking and investment. The optimal level of transfer payments is where the marginal social benefit of redistribution equals the marginal social cost of the distortions introduced.
经济学家从公平与效率的权衡角度来评估转移支付。在公平方面，转移支付能减少贫困并提供安全网，这可以增强社会凝聚力，并可能通过改善健康和教育促进长期增长。在效率方面，高额转移支付需要高税收，可能扭曲劳动与闲暇的选择，并降低冒险和投资的激励。转移支付的最优水平，是再分配的边际社会收益等于其所引入扭曲的边际社会成本。
10. Government Budget and Fiscal Policy | 政府预算与财政政策
Transfer payments constitute a major component of government current expenditure. During fiscal consolidation periods, governments often target welfare budgets for cuts, which can be controversial. In contrast, during a recession, discretionary increases in transfer payments—such as one-off bonus payments to pensioners or extended unemployment benefits—form part of expansionary fiscal policy. The sustainability of transfer systems is increasingly questioned in the context of ageing populations, which raise the dependency ratio and place upward pressure on pensions and healthcare transfers.
转移支付构成政府经常性支出的主要部分。在财政整顿期间，政府往往将削减福利预算作为目标，这可能引发争议。相反，在经济衰退期间，相机抉择地增加转移支付——例如向退休人员发放一次性补助金或延长失业救济——是扩张性财政政策的一部分。在人口老龄化的背景下，转移支付体系的可持续性受到越来越多的质疑，因为老龄化提高了抚养比，并对养老金和医疗保健转移支付产生上行压力。
