📚 IGCSE Economics: Balance of Payments Current Account Analysis | IGCSE经济：国际收支经常账户解析
The balance of payments is a record of all financial transactions between one country and the rest of the world over a period of time, usually one year. It is divided into two main accounts: the current account and the financial/capital account. This article focuses on the current account, which records trade in goods, services, income, and transfers.
国际收支是一个国家在一定时期内（通常为一年）与世界上其他国家之间所有金融交易的记录。它分为两大账户：经常账户和金融/资本账户。本文重点解析经常账户，它记录货物贸易、服务贸易、收入和转移支付。
1. The Structure of the Current Account | 经常账户的结构
The current account is sub-divided into four main components: trade in goods (visible trade), trade in services (invisible trade), primary income (investment income and wages), and secondary income (current transfers such as foreign aid and remittances).
经常账户可细分为四个主要部分：货物贸易（有形贸易）、服务贸易（无形贸易）、初次收入（投资收入和工资）以及二次收入（经常转移，如外国援助和汇款）。
Trade in goods: exports and imports of physical items, e.g. cars, food, oil.
货物贸易：有形物品的进出口，例如汽车、食品、石油。
Trade in services: exports and imports of non-physical items, e.g. banking, tourism, insurance.
服务贸易：无形项目的进出口，例如银行、旅游、保险。
Primary income: net earnings on foreign investments minus payments to foreign investors, plus net wages earned by cross-border workers.
初次收入：对外投资净收益减去支付给外国投资者的款项，加上跨境工人的净工资。
Secondary income: transfers of money with no goods or service in return, including foreign aid, remittances, and donations.
二次收入：没有对应货物或服务回报的资金转移，包括外国援助、汇款和捐赠。
2. Why Is the Current Account Important? | 为什么经常账户重要？
The current account shows how much a country earns from selling goods and services abroad and from income flows, compared with how much it spends on foreign goods, services, and transfers. A persistent deficit may indicate a lack of competitiveness, while a large surplus may reflect strong export performance but can also create trade tensions.
经常账户显示一个国家通过向国外出售货物和服务以及收入流入所赚取的金额，与其在外国货物、服务和转移上的支出相比如何。持续性赤字可能表明竞争力不足，而巨额盈余可能反映强劲的出口表现，但也可能引发贸易紧张。
For IGCSE economics, understanding the current account helps explain a country's external economic position and its links with exchange rates, employment, and economic growth.
对于IGCSE经济学而言，理解经常账户有助于解释一个国家的对外经济地位，以及它与汇率、就业和经济增长之间的联系。
3. How to Measure the Current Account Balance | 如何衡量经常账户余额
The current account balance is calculated as the sum of all credits (exports and income received) minus all debits (imports and income paid). The formula can be expressed as:
经常账户余额的计算方法是所有贷项（出口和收到的收入）减去所有借项（进口和支付的收入）。公式可以表示为：
f Goods + Exports of Services + Primary Income Received + Secondary Income Received) − (Imports of Goods + Imports of Services + Primary Income Paid + Secondary Income Paid)
经常账户余额 =（货物出口 + 服务出口 + 收到的初次收入 + 收到的二次收入）−（货物进口 + 服务进口 + 支付的初次收入 + 支付的二次收入）
If the total is positive, the current account is in surplus. If negative, it is in deficit. If zero, it is balanced.
如果总额为正，则经常账户为盈余。如果为负，则为赤字。如果为零，则为平衡。
4. Current Account Surplus and Deficit | 经常账户盈余与赤字
A current account surplus means the country receives more money from abroad than it sends out. This often results from strong export performance, high competitiveness, or a high savings rate relative to investment.
经常账户盈余意味着该国从国外收到的资金多于其向国外支付的资金。这通常源于强劲的出口表现、较高的竞争力，或相对于投资而言较高的储蓄率。
A current account deficit means the country spends more on foreign goods, services, income, and transfers than it earns from these items. This may be financed by borrowing from abroad or by attracting foreign investment.
经常账户赤字意味着该国在外国货物、服务、收入和转移上的支出多于其从这些项目中赚取的金额。这可以通过从国外借款或吸引外国投资来融资。
Neither a surplus nor a deficit is automatically 'good' or 'bad'. The interpretation depends on the causes, the duration, and the overall economic context.
盈余和赤字本身都不自动意味着“好”或“坏”。其解释取决于原因、持续时间以及整体经济背景。
5. Causes of a Current Account Deficit | 经常账户赤字的原因
A current account deficit may be caused by several factors:
经常账户赤字可能由多种因素引起：
Low price competitiveness: domestic inflation is higher than trading partners, making exports more expensive and imports cheaper.
价格竞争力低：国内通货膨胀高于贸易伙伴，导致出口更贵、进口更便宜。
Unproductive domestic industries: poor-quality goods, outdated technology, or weak infrastructure reduce export capacity.
国内产业生产力不足：产品质量差、技术落后或基础设施薄弱会降低出口能力。
Strong domestic demand: consumer spending on imports rises when the economy grows, pushing up import expenditure.
国内需求强劲：经济增长时消费者对进口商品的花费增加，推动进口支出上升。
High exchange rate: an overvalued currency makes exports less competitive and imports cheaper.
高汇率：本币高估使出口竞争力下降，进口更便宜。
Structural factors: a country may lack natural resources or raw materials, forcing it to import essential goods.
结构性因素：一个国家可能缺乏自然资源或原材料，迫使它进口必需品。
6. Causes of a Current Account Surplus | 经常账户盈余的原因
A current account surplus can also arise from various reasons:
经常账户盈余也可以由多种原因产生：
High competitiveness in export industries, such as strong brands, advanced technology, and high productivity.
出口产业的高度竞争力，如强大的品牌、先进的技术和高生产率。
Low domestic demand relative to output, so a large share of production is exported.
国内需求相对于产出较低，因此很大一部分生产用于出口。
A depreciated exchange rate that makes exports cheaper for foreign buyers.
汇率贬值使出口商品对外国买家更便宜。
Trade barriers in other countries or preferential trade agreements that boost exports.
其他国家的贸易壁垒或优惠贸易协定促进了出口。
A high household saving rate, which reduces import spending and frees resources for export.
家庭储蓄率高，减少了进口支出并为出口释放资源。
7. Economic Consequences of a Deficit | 经常账户赤字的后果
A persistent current account deficit may have negative consequences:
持续经常账户赤字可能带来负面后果：
Depreciation of the currency: continued deficit puts downward pressure on the exchange rate as the country sells its currency to buy foreign currency.
货币贬值：持续赤字对汇率构成下行压力，因为该国出售本币以购买外币。
Higher foreign debt: the deficit must be financed by borrowing from abroad, which raises external debt and interest payments.
外债增加：赤字必须通过从国外借款来融资，这提高了外债和利息支付。
Loss of domestic jobs: import competition may reduce demand for domestic goods, causing unemployment in import-competing industries.
国内失业：进口竞争可能减少对国内商品的需求，导致进口竞争行业失业。
Reduced economic growth: if the deficit reflects weak exports, aggregate demand falls, slowing growth.
经济增长放缓：如果赤字反映出口疲软，总需求下降，从而减缓增长。
However, a temporary deficit may be acceptable if it is caused by importing capital goods to improve future productivity, or if the economy is growing strongly.
然而，如果临时赤字是由于进口资本品以提高未来生产力，或经济强劲增长所致，则可能是可以接受的。
8. Economic Consequences of a Surplus | 经常账户盈余的后果
A current account surplus also carries both benefits and costs:
经常账户盈余同样带来好处和代价：
Currency appreciation pressure: a surplus increases demand for the domestic currency, pushing up the exchange rate.
本币升值压力：盈余增加了对本币的需求，推高汇率。
Possible inflationary pressure: an inflow of money may increase the money supply and contribute to demand-pull inflation.
可能的通胀压力：资金流入可能增加货币供应，并促成需求拉动型通货膨胀。
Trade conflicts: large surpluses may lead to protectionist measures by trading partners.
贸易冲突：巨额盈余可能导致贸易伙伴采取保护主义措施。
Higher national income and employment: surplus economies often enjoy stronger output growth and more jobs in export sectors.
更高的国民收入和就业：盈余经济体通常享有更强劲的产出增长和更多的出口部门就业。
Accumulation of foreign reserves: a surplus can help a country build up reserves to stabilise its currency.
外汇储备积累：盈余可以帮助一个国家积累储备以稳定其货币。
9. Policies to Correct a Current Account Deficit | 纠正经常账户赤字的政策
Governments may adopt various policies to reduce a deficit. These are often classified as expenditure-reducing and expenditure-switching policies.
政府可能采取各种政策来减少赤字。这些通常分为支出减少政策和支出转换政策。
| Policy | 政策 | Method | 方法 | Likely effect | 可能效果 |
| Deflationary measures 紧缩政策 | Higher taxes, lower government spending, higher interest rates 增税、减少政府支出、提高利率 | Reduces import spending and inflation 减少进口支出和通胀 |
| Depreciation of currency 货币贬值 | Let the exchange rate fall or intervene financially 让汇率下跌或进行金融干预 | Makes exports cheaper, imports dearer 使出口更便宜，进口更贵 |
| Supply-side policies 供给侧政策 | Improve education, infrastructure, R&D 改善教育、基础设施、研发 | Raises productivity and export competitiveness 提高生产率和出口竞争力 |
| Trade protection 贸易保护 | Tariffs, quotas, subsidies 关税、配额、补贴 | Reduces imports, but may cause retaliation 减少进口，但可能引起报复 |
Each policy has limitations. For example, deflation may cause unemployment, and protectionism may harm long-run efficiency and trigger retaliation.
每项政策都有局限性。例如，紧缩可能导致失业，而保护主义可能损害长期效率并引发报复。
10. Policies to Reduce a Current Account Surplus | 减少经常账户盈余的政策
When a country has a large persistent surplus, it may choose to rebalance the economy rather than maximise the surplus. Common methods include:
当一个国家有大量持续盈余时，它可能选择重新平衡经济，而不是最大化盈余。常见方法包括：
Expansionary fiscal policy: lower taxes and higher government spending boost domestic demand and increase imports.
扩张性财政政策：减税和增加政府支出刺激国内需求并增加进口。
Loosening monetary policy: lower interest rates encourage borrowing and spending, including on imported goods.
宽松货币政策：降低利率鼓励借贷和消费，包括对进口商品的消费。
Appreciation of the currency: allowing the exchange rate to rise makes exports more expensive and imports cheaper.
本币升值：允许汇率上升使出口更贵、进口更便宜。
Reducing trade barriers: lowering tariffs or quotas allows more imports to flow in.
降低贸易壁垒：降低关税或配额允许更多进口流入。
11. Interpreting Current Account Data: A Worked Example | 解读经常账户数据：一个计算示例
Suppose a country has the following figures in millions of dollars:
假设一个国家有以下数据，单位为百万美元：
= 40; Primary income paid = 30; Secondary income received = 10; Secondary income paid = 20
货物出口 = 250；货物进口 = 300；服务出口 = 120；服务进口 = 80；收到的初次收入 = 40；支付的初次收入 = 30；收到的二次收入 = 10；支付的二次收入 = 20
Calculate the current account balance:
计算经常账户余额：
Current Account = (250 + 120 + 40 + 10) − (300 + 80 + 30 + 20) = 420 − 430 = −10 million
经常账户 = (250 + 120 + 40 + 10) − (300 + 80 + 30 + 20) = 420 − 430 = −1000万美元
The country runs a current account deficit of $10 million. The goods deficit is 50, but the services surplus of 40 reduces the total deficit.
该国经常账户赤字为1000万美元。货物逆差为5000万，但服务顺差4000万减少了总赤字。
12. Current Account and the Circular Flow of Income | 经常账户与收入循环流动
I + G + (X − M). Exports are an injection into the circular flow, while imports are a withdrawal.
在开放经济中，经常账户是总需求的一部分：AD = C + I + G + (X − M)。出口是收入循环流动中的注入，进口则是漏出。
If (X − M) is positive, net injections raise national income, creating a multiplier effect. If negative, net withdrawals reduce income and may lead to a slowdown in growth.
如果 (X − M) 为正，净注入会提高国民收入，产生乘数效应。如果为负，净漏出会减少收入，并可能导致增长放缓。
For IGCSE exams, remember that the current account only records income flows, not purchases or sales of financial assets. Those belong to the financial account.
对于IGCSE考试，请记住经常账户只记录收入流，而不是金融资产的买卖。那些属于金融账户。
