For most of the last forty years, "industrial policy" was a phrase American economists used mostly as a warning. Today it shapes laws worth hundreds of billions of dollars, fills the agendas of both political parties, and drives decisions about where the next chip fab, battery plant, or shipyard will go.
So what is industrial policy, exactly? Where has it worked, where has it failed, and what does the newest research say? Here's a clear, plain-English guide.
Industrial policy, defined
Economists Réka Juhász, Nathan Lane, and Dani Rodrik offer the most widely cited modern definition. In their 2024 review in the Annual Review of Economics, they define industrial policy as government policies that explicitly aim to transform the structure of economic activity in pursuit of some public goal.
Three ideas sit inside that definition:
- It's deliberate. Every policy affects some industries more than others. Industrial policy chooses which industries, technologies, or regions to grow.
- It targets structure. The goal is a different economy: more advanced manufacturing, a domestic semiconductor supply, cleaner energy, a stronger defense industrial base.
- It serves a public goal. That goal might be good jobs, national security, regional development, or climate. Supporters and critics argue mainly about whether governments can pursue those goals well.
The industrial policy toolkit
Industrial policy uses many tools, and tariffs are only one of them. The main instruments include:
- Subsidies and grants for firms that build in a target industry or place
- Tax credits for investment, production, or research
- Tariffs and quotas that shield young industries from imports (see our guide to protectionism vs. free trade)
- Government procurement, where the state acts as a first, reliable customer
- Public research and development, from national labs to DARPA
- Public finance, such as development banks and loan guarantees
- Infrastructure, training, and standards that let a cluster of firms grow together
Modern industrial policy leans heavily on the targeted tools. A text-analysis study of thousands of government policies worldwide found that industrial policy makes up roughly a quarter of the policies in its database and has expanded since 2010, and that most of it is granular and technocratic rather than blunt tariffs.
Industrial policy examples from history
The United States. America's first industrial policy came from its first Treasury Secretary. In his 1791 Report on Manufactures, Alexander Hamilton argued that a young country needed active government help to build manufacturing against established British competition. Henry Clay later turned those ideas into the "American System" of tariffs, a national bank, and roads and canals. We tell that story in The American System: Hamilton, Henry Clay, and America's First Industrial Policy.
Napoleonic France. Economist Réka Juhász studied a natural experiment: during the Napoleonic Wars, some French regions were cut off from British trade more than others. The more-shielded regions expanded mechanized cotton spinning faster and kept higher activity in that industry for decades. Temporary protection helped a young industry adopt new technology.
South Korea. From 1973 to 1979, South Korea's Heavy and Chemical Industry drive pushed firms into steel, shipbuilding, machinery, and petrochemicals. Nathan Lane's study in the Quarterly Journal of Economics found that targeted industries grew their output by more than 100% relative to non-targeted manufacturing, that downstream industries benefited too, and that the gains outlasted the policy itself.
Japan. After World War II, Japan's Ministry of International Trade and Industry (MITI) steered credit, technology licenses, and import access toward industries such as steel, autos, and electronics. Economists still debate how much credit MITI deserves for Japan's boom, which makes it one of the richest case studies in the field.
Today's America. The 2022 CHIPS and Science Act provides $52.7 billion to revitalize the domestic semiconductor industry, including $39 billion in manufacturing incentives run by the Commerce Department. It is the clearest example of a modern U.S. industrial policy: targeted at one strategic industry, delivered mostly through grants and tax credits, and justified by both economics and national security.
When industrial policy fails
Honest study of industrial policy includes its failures. The Anglo-French Concorde program poured public money into a supersonic jet that only Britain's and France's own national airlines ever bought. Many countries in Latin America sheltered industries behind high tariffs for decades without forcing them to become competitive, and consumers paid higher prices for lower-quality goods.
The common threads in failed programs are well known: support with no end date, no performance requirements, and political pressure to keep funding firms long after they should have stood on their own. South Korea's programs, by contrast, often tied support to export performance, so firms had to prove themselves in world markets.
The case for and against
The case for industrial policy rests on market failures that economists broadly accept:
- Learning by doing. Costs fall as an industry produces more, so a young industry may never reach its efficient scale without early support.
- Spillovers. Know-how spreads among clusters of firms, suppliers, and workers, so no single firm captures the full benefit of building an industry.
- Coordination. A chip fab needs suppliers, engineers, water, power, and customers all at once. Markets alone can struggle to coordinate that.
- Security and resilience. Some capacities, such as advanced chips or munitions, carry value that prices don't capture.
The case against focuses on government failure. Officials may lack the information to choose well, and well-connected firms may capture the subsidies. Programs cost taxpayers money, and other countries may retaliate.
Juhász, Lane, and Rodrik conclude that the newest research, which uses better data and more careful methods than earlier correlational studies, supports a more favorable view of industrial policy. For most economists working on the subject today, the real question is less whether governments should pursue industrial policy and more how to design it well.
Why industrial policy matters for your career
Industrial policy now runs through the work of agency staff, congressional offices, think tanks, trade associations, and companies deciding where to invest. Yet very few universities teach it directly.
That's why we built the Industrial Policy Executive Certificate with Ian Fletcher, coauthor with Marc Fasteau of Industrial Policy for the United States (Cambridge University Press, 2024). Over 12 weeks, you watch Fletcher's recorded lectures, work through the case studies above and many more, and meet with him one-on-one to sharpen your own policy writing. Like every Elton program, it is taught by a human expert who knows your work, not by an AI.
