A decision you can investigate
- Two fictional countries export different product mixes. One relies heavily on crops, while the other sells manufactured goods and services.
- A development label alone does not tell us every country’s pattern.
Build the explanation
- Trade patterns describe the goods/services traded, partners and composition of flows. Resource endowments, skills, technology, infrastructure, income and investment help explain them. Some developing economies depend on primary exports; others export substantial manufactured goods or services.
- More developed economies often trade sophisticated manufactures and services, but can also export natural resources. Diversification 多样化 can reduce reliance on one market or volatile product price; it requires capability and access.
Work through the evidence
- Fictional A exports 60 million in primary goods, 30 in manufactures and 10 in services: primary share = 60/100 × 100 = 60%. B exports 20, 120 and 60 respectively: primary share = 20/200 × 100 = 10%.
- If A’s primary export value rises to 66 while total exports rise to 120, its primary share falls to 55% despite a higher primary-export value. Changes in price can alter export value without a matching quantity change.
What is B’s primary-export share?
20 divided by total 200 equals 10%.
Test the limits
- These are illustrative economies, not statistics for a real country. Use dated country data before making a real-world comparison. A single export share cannot rank quality of life.
- Development, policy, FDI and exchange rates can change the pattern. Ask whether values are nominal, which services are included, and whether the same definitions and periods are used.
A exports primary goods worth 66 out of total 120. Its share is
66/120 × 100 = 55%.
Every developing economy exports only primary goods.
Manufacturing and services can be important; actual composition needs evidence.
Apply and explain your answer
- Why can A’s primary-export share fall while its primary exports rise?
- Total exports grow faster than primary-export value.
Why can export value rise without more units?
Value depends on both prices and quantities.
Use the terms precisely
- export composition 出口构成: The distribution of export value across categories.
- diversification: Reducing concentration by developing a wider range of products or markets.
Match the terms to their meanings.
Each term describes a specific mechanism in this lesson.
