Business and its environment (A Level) · ⁨ธุรกิจและสภาพแวดล้อม (A Level)⁩

A business cannot control everything. External influences 外部影响 are forces outside the firm that affect how it works. The firm must watch them and adapt. We group them into economic factors and wider (political, legal, social and other) factors.

The business cycle 经济周期 is the way the whole economy rises and falls over time. It has four stages:

• boom 繁荣 — fast growth; high demand, but rising costs and prices.
• recession 衰退 — falling demand and output; sales drop and some firms close.
• slump 萧条 — a deep, long recession with very low demand.
• recovery 复苏 — demand and output start to rise again.

In a boom, firms expand; in a recession, they cut costs, hold less stock, and may aim only to survive.

The interest rate 利率 is the price of borrowing money, set as a percentage. When interest rates rise:

• loans and mortgages cost more, so customers spend less.
• firms with loans pay more, which lowers their profit.
• new investment is less likely, because borrowing is dear.

When interest rates fall, the opposite happens and spending usually rises.

The exchange rate 汇率 is the price of one currency in terms of another. It changes all the time.

• if the local currency rises in value (appreciation 升值), exports become dearer abroad and imports become cheaper.
• if the local currency falls in value (depreciation 贬值), exports become cheaper abroad and imports become dearer.

So an exporter 出口商 often gains from a weaker currency, while an importer 进口商 often gains from a stronger one.

Inflation 通货膨胀 is a general rise in prices over time. High inflation raises a firm's costs (materials and wages), makes planning harder, and can cut what customers can afford to buy. Low, steady inflation is usually best for business.

Taxation 税收 is money the government takes from people and firms.

• a direct tax 直接税 is taken from income or profit (e.g. income tax, corporation tax).
• an indirect tax 间接税 is added to spending (e.g. sales tax on goods).

Higher taxes leave people and firms with less money to spend, so demand falls.

Unemployment 失业 is the number of people who want work but cannot find it. High unemployment lowers demand, but it also makes workers easier and cheaper to hire.

Worked example. A house-builder has £8m of variable-rate loans. The central bank raises interest rates from 2% to 5%. Explain the effect on this business. Answer on both sides. On costs: annual interest rises from 8m × 0.02 = £160,000 to 8m × 0.05 = £400,000, so £240,000 comes straight off profit. On demand: mortgages become dearer, so fewer buyers can afford a house - and because houses are bought on credit and are a postponable purchase, demand falls sharply. Both effects strike this firm at once, which is why a highly geared house-builder is unusually sensitive to interest rates. Always give the cost of borrowing and the demand effect, and tie the size of the demand effect to whether the product is bought on credit - the same rate rise barely touches a firm selling cheap everyday goods with no debt.

• political 政治 — government decisions, trade rules and stability affect how firms plan.
• legal 法律 — firms must obey legislation 法规 on employment, consumer safety, competition and the environment. Breaking the law brings fines and bad publicity.
• social 社会 — changes in society, such as ageing populations or new tastes, change what people buy.

• technological 技术 — new technology can create new products and cut costs, but firms must keep up or fall behind.
• environmental 环境 — firms face pressure and rules to cut pollution and waste, and to act in a sustainable way.
• ethical 道德 — acting in a morally right way (fair pay, honest selling) builds trust, even if it costs more.

Together these wider factors are often studied with a PESTLE analysis 宏观环境分析, which checks Political, Economic, Social, Technological, Legal and Environmental forces.

A strategy 战略 is a long-term plan to reach the firm's main objectives. Strategic management 战略管理 is the work of setting that plan, putting it into action, and checking it. Good strategy aims to build a competitive advantage 竞争优势 — a reason customers choose you over rivals, such as lower cost or a better product.

A SWOT analysis SWOT分析 studies a firm's position under four headings:

A firm should use its strengths to take opportunities, and fix or protect against its weaknesses and threats.

Firms use other tools to make decisions, such as decision trees (weighing choices by their likely results) and the matrices you meet later in marketing and operations. Every planning tool turns information about the business and its environment into a clearer choice.

• Explain how a change in interest rates, the exchange rate or inflation affects a firm on both the cost and the demand side.
• A stronger exchange rate makes exports dearer and imports cheaper (SPICED / WPIDEC).
• Use SWOT correctly: strengths and weaknesses are internal, opportunities and threats are external.
• Support a strategy with a PEST/PESTLE scan of the external environment.
