In 30 seconds
- Industrial policy is government action to shift the economy towards chosen sectors, using credit, subsidies, tariffs, public investment and state firms.
- A developmental state has a capable bureaucracy that disciplines firms: support is given in return for results, usually export targets.
- The infant industry argument: new firms need temporary protection until they learn to compete.
- Import substitution (ISI) protected home markets; export promotion pushed firms to sell abroad. East Asia’s export focus generally did better than Latin America’s ISI.
- Risks: picking losers, corruption, rent-seeking and debt.
Why governments intervene
Markets may under-invest in new industries because the gains spill over to other firms (learning, trained workers, suppliers), because banks will not lend for long periods, or because many linked investments must happen together. Industrial policy tries to solve these coordination failures and capture dynamic comparative advantage: an advantage a country can build, not just inherit.
Key termsInfant industry: a new industry that cannot yet match established foreign rivals. Rent-seeking: firms spending effort to win state favours rather than to become productive. Developmental state: a state that directs investment towards growth through capable, relatively insulated institutions.
ISI versus export promotion
| Import substitution | Export promotion | |
|---|---|---|
| Main tools | High tariffs, quotas, overvalued currency | Cheap credit, export subsidies, competitive currency |
| Test of success | Home market share | Sales in world markets |
| Typical result | Inefficient firms, balance-of-payments crises | Fast learning, scale economies, foreign exchange |
| Examples | Argentina, Brazil, India before 1991 | South Korea, Taiwan, China after 1978 |
Worked example
A government protects a new steel firm with a 30% tariff for eight years. When is this justified?
1Cost: consumers and steel users pay up to 30% more each year of protection.
2Benefit: if the firm learns and its costs fall below world prices, the economy gains cheaper steel and exports for decades after.
3Conditions: protection must be temporary, tied to performance (such as export targets) and removed on schedule.
ResultJustified only if future gains outweigh today’s costs and the state can credibly withdraw support. Korea’s steelmaker POSCO is a success case; many protected firms elsewhere never grew up.

Common mistakeSaying “East Asia grew through free markets.” Korea and Taiwan used heavy state direction of credit and trade. The lesson is about disciplined intervention tied to export performance, not about no intervention.
Exam tipFor “market-led vs state-led” questions, argue that the quality of the state matters most: the same tools worked in Korea and failed where bureaucracies were weak or captured.
Practise: 6 questions
Try each one on paper first, then check the worked answer.
EasyQ1. Define industrial policy. Show worked answer
Government measures that aim to change the structure of the economy towards particular industries or activities, for example through subsidies, credit, tariffs or public investment.
EasyQ2. State the infant industry argument. Show worked answer
New industries need temporary protection from foreign competition until they gain experience and scale and can compete on their own.
MediumQ3. Give two reasons import substitution often failed. Show worked answer
Protected firms faced no competition, so they stayed inefficient; small home markets prevented economies of scale; overvalued currencies hurt exports and caused balance-of-payments crises.
MediumQ4. What is meant by “reciprocity” in Korea’s industrial policy? Show worked answer
Support (cheap credit, licences) was given in return for performance, mainly export targets. Firms that missed targets lost support, which limited rent-seeking.
MediumQ5. Give two risks of the chaebol model. Show worked answer
Concentration of economic and political power in a few conglomerates; “too big to fail” behaviour and heavy debt, which contributed to the 1997 Asian financial crisis.
ExamQ6. Evaluate whether other developing countries can copy South Korea’s development strategy. [10] Show worked answer
Can copy: export discipline, investment in education, infrastructure and learning [3]. Hard to copy: WTO rules now limit export subsidies and tariffs [2]; Korea had a capable bureaucracy, land reform and Cold War aid [2]; automation and China’s scale make manufacturing entry harder [1]. Judgement: the principles transfer (performance-linked support, human capital), the exact tools do not; Ethiopia’s mixed record shows the difficulty [2].
Check yourself
1. Export promotion judges firms by
Export targets give an objective test of competitiveness.
2. Rent-seeking means
It wastes resources on lobbying for protection or subsidies.
3. A main reason industrial policy is harder today is
Trade rules limit many tools East Asia used in the 1960s–80s.
Your score: 0 out of 3
The short version
- Industrial policy fixes coordination failures and builds new advantages.
- East Asia tied support to export results; ISI often bred inefficiency.
- State capability decides success; rent-seeking is the main risk.
- Use Korea (case 64) and Ethiopia (case 66).
