Industrial policy has re-emerged as a central issue in economic policymaking. After several decades during which market-oriented reforms and trade liberalization dominated policy agendas, governments around the world have once again embraced active industrial strategies to promote strategically important sectors. Intensifying technological competition, the urgency of climate change, concerns over supply-chain resilience, and national security considerations have all strengthened the case for greater government intervention in the economy.
China has been at the center of this renewed debate. Through industrial planning and a broad range of policy instruments, it has fostered the rapid development of industries such as solar photovoltaics (PV), electric vehicles (EVs), and advanced batteries. These achievements, however, have also generated considerable controversy. Many trading partners argue that government support has conferred unfair competitive advantages on Chinese firms and contributed to global trade imbalances. The European Union’s anti-subsidy investigation into Chinese EVs illustrates how industrial policy has become an increasingly prominent source of international trade friction.
China is by no means unique in relying on industrial policy. Similar approaches have become widespread among advanced economies. The United States has enacted the Inflation Reduction Act and the CHIPS and Science Act to support clean-energy technologies and semiconductor manufacturing. The European Union has introduced the Green Deal Industrial Plan to strengthen low-carbon industries, while Japan and South Korea have expanded support for semiconductors, batteries, and hydrogen technologies. Industrial policy has thus become a global phenomenon rather than a uniquely Chinese practice.
The renewed interest in industrial policy reflects the existence of genuine market failures. Innovation generates knowledge spillovers that private firms cannot fully appropriate, leading to underinvestment in research and development. Emerging industries often face high initial production costs that decline only as firms accumulate production experience. Technologies such as electric vehicles also exhibit network externalities, as consumers are reluctant to adopt them until complementary infrastructure, such as charging networks, becomes sufficiently widespread. In addition, renewable energy and other low-carbon technologies create environmental benefits by reducing greenhouse gas emissions—benefits that are only imperfectly reflected in market prices. In each of these cases, private investment is likely to fall short of the socially optimal level.
At the same time, industrial policy raises important concerns about competitive neutrality. Subsidies that persist after an industry has become commercially mature may encourage excessive investment, generate overcapacity, depress international prices, and provoke retaliatory trade measures. The central policy question is therefore not whether governments should employ industrial subsidies, but under what conditions such interventions enhance social welfare, and at what point they begin to undermine economic efficiency and fair competition.
This essay argues that the economic justification for subsidies depends fundamentally on the stage of industrial development. During the early phases of an industry’s evolution, temporary subsidies can accelerate learning, stimulate innovation, and help overcome market failures. As industries mature and become commercially viable, however, the rationale for continued government support progressively weakens. If subsidies persist beyond this point, they risk creating excess capacity, distorting international competition, and reducing global welfare. Effective industrial policy should therefore adopt a dynamic approach: providing support during the infant stage, gradually withdrawing it as industries mature, and avoiding persistent over-subsidization.
Building on this framework, the article proposes an international trade arrangement that distinguishes between welfare-enhancing and distortionary subsidies. Rather than relying primarily on unilateral countervailing duties imposed by importing countries, the trading system should, where feasible, neutralize excessive producer subsidies through an internationally supervised mechanism under the auspices of the World Trade Organization (WTO). Such an arrangement would preserve governments’ ability to foster innovation and address market failures while safeguarding fair competition in international trade.
The Usefulness of Subsidies
Subsidies are among the most important instruments of industrial policy because they directly influence firms’ investment decisions, production activities, and innovation incentives. Although they are frequently criticized for distorting market outcomes, economic theory identifies several circumstances in which subsidies can improve economic efficiency by correcting market failures. These include learning-by-doing, the infant industry problem, network externalities, capital market imperfections, and environmental externalities. In such cases, well-designed government intervention can increase both national and global welfare.
The infant industry argument has long occupied a prominent place in economic thought. Newly emerging industries often begin with production costs that are too high for them to be immediately commercially viable. These high costs, however, do not necessarily reflect permanent inefficiency. Rather, they often arise because firms have not yet accumulated sufficient production experience. As production expands, firms improve manufacturing processes, workers acquire skills, supply chains become more efficient, and economies of scale are realized, causing average costs to decline over time. Temporary government support can therefore enable industries with strong long-term potential to survive the early stages of development and eventually become commercially viable.
This process is commonly described by the learning curve, which captures the systematic decline in production costs as cumulative output increases. Learning curves have been documented across a wide range of manufacturing industries and are particularly evident in modern clean-energy technologies, where technological progress depends heavily on production experience.
The solar PV industry provides one of the clearest illustrations. During the 1970s and 1980s, electricity generated from solar PV remained prohibitively expensive for large-scale commercial deployment. Governments in Japan, Germany, the United States, and later China supported the industry’s development through research funding, investment incentives, and deployment subsidies. As cumulative production expanded, manufacturers continuously refined production processes, improved product quality, and achieved substantial economies of scale.
According to the International Renewable Energy Agency (IRENA), the global levelized cost of electricity generated from utility-scale solar PV declined by nearly 90 percent between 2010 and 2022, while module prices fell by a comparable magnitude. What was once regarded as an expensive niche technology has become one of the world’s most cost-competitive sources of electricity. Importantly, these cost reductions benefit consumers worldwide, regardless of which countries initially financed the subsidies that accelerated technological learning.
Lithium-ion batteries exhibit a similar pattern. In 2010, battery packs cost well over $1,000 per kilowatt-hour, making electric vehicles prohibitively expensive for most consumers. Continuous advances in battery chemistry, manufacturing technology, automation, and production scale have dramatically reduced costs. BloombergNEF estimates that the average battery pack price had fallen below $140 per kilowatt-hour by 2023, bringing electric vehicles much closer to cost parity with conventional internal combustion engine vehicles.
These examples illustrate how temporary subsidies can generate lasting social benefits by accelerating technological learning and innovation. Without sufficient early production, firms would accumulate experience much more slowly, delaying cost reductions that ultimately benefit consumers around the world.
Network Externalities and Capital Market Imperfections
Learning-by-doing represents only one source of market failure. Many emerging technologies also exhibit network externalities, whereby the value of a product depends on the number of other users or the availability of complementary infrastructure.
Electric vehicles provide a clear example. Consumers may hesitate to purchase EVs because charging stations remain scarce, while investors may be reluctant to build charging infrastructure because too few consumers own EVs. This coordination problem can prevent an otherwise efficient technology from reaching the critical mass necessary for widespread adoption. Temporary subsidies for either vehicle purchases or charging infrastructure can help the market overcome this coordination failure and move toward a self-sustaining equilibrium.
Emerging industries may also face severe financing constraints. In principle, firms could borrow to finance temporary losses until production costs decline through learning and scale economies. In practice, however, private investors are often reluctant to finance projects characterized by substantial technological uncertainty. Banks may be unwilling to lend to firms lacking established cash flows, proven business models, or sufficient collateral. Government support can therefore compensate for imperfections in capital markets by enabling socially valuable investments that private financiers would otherwise be unwilling to undertake.
Environmental Externalities
Industrial policy may also be justified when new technologies generate significant positive environmental externalities. Climate change provides perhaps the most important contemporary example.
Carbon emissions impose substantial costs on society that are not fully reflected in market prices. As a consequence, markets tend to underinvest in low-carbon technologies such as renewable energy, electric vehicles, advanced batteries, hydrogen, and carbon capture. Subsidies help correct this market failure by encouraging the production and adoption of technologies whose social benefits exceed their private returns.
Most economists regard carbon pricing as the first-best policy for addressing climate change because it directly internalizes the environmental costs of greenhouse gas emissions. In practice, however, political constraints often prevent governments from adopting carbon taxes or emissions pricing mechanisms that are sufficiently stringent. Under these circumstances, subsidies constitute an important second-best policy instrument. By accelerating technological progress, lowering future production costs, and encouraging wider adoption of clean technologies, they facilitate the transition to a low-carbon economy while partially compensating for the absence of optimal carbon pricing.
A Dynamic View of Industrial Policy
The economic justification for industrial subsidies is inherently dynamic rather than static. Whether a subsidy enhances or reduces welfare depends not only on its size or form but also on the stage of industrial development at which it is applied. Policies that are highly beneficial during the emergence of an industry may become increasingly distortionary once the industry reaches commercial maturity. Consequently, industrial policy should evolve alongside the industries it seeks to support.
During the first stage, an industry is in its infancy. Production costs remain high, technological uncertainty is substantial, consumer acceptance is limited, and firms often face significant financing constraints. At this stage, learning-by-doing is particularly important, network externalities impede market expansion, and private investment typically falls short of the socially optimal level. Temporary subsidies can therefore play a critical role in accelerating technological learning, encouraging investment, and facilitating market adoption. By helping firms move down the learning curve more rapidly, such policies not only benefit domestic producers but also generate knowledge spillovers and lower costs that ultimately benefit consumers worldwide.
As the industry expands, it enters a second stage of commercial development. Technological capabilities improve, production costs decline, supply chains mature, and firms become commercially viable without extraordinary government assistance. Many of the market failures that initially justified intervention gradually diminish. Learning effects become weaker, financial markets gain greater confidence in the industry, and consumer acceptance increases as complementary infrastructure expands.
At this stage, the rationale for broad production subsidies becomes considerably weaker. Government support should progressively shift away from subsidizing production toward addressing the remaining market failures that continue to justify public intervention. These may include support for basic scientific research, policies aimed at reducing greenhouse gas emissions, or investments in public infrastructure that facilitate the adoption of new technologies. In other words, industrial policy should evolve from promoting industrial expansion to correcting residual externalities.
If subsidies continue beyond this point, the industry may enter a third stage, in which government support itself becomes a source of market distortion. Persistent subsidies encourage firms to expand production capacity beyond socially efficient levels, even when market demand no longer justifies such investment. Excess capacity depresses international prices, intensifies trade disputes, and diverts public resources toward industries that are already commercially viable. Rather than correcting market failures, subsidies begin to create new distortions, reducing both domestic and global welfare.
This dynamic perspective implies that the effectiveness of industrial policy depends not only on whether governments intervene but also on whether they withdraw support at the appropriate time. The central challenge for policymakers is therefore one of policy timing. Introducing subsidies too late may fail to overcome the barriers faced by emerging industries, while maintaining them for too long risks encouraging inefficiency and undermining fair competition. Successful industrial policy requires not only the capacity to identify promising industries but also the discipline to phase out support once its original economic justification has disappeared.
This framework also helps reconcile two seemingly conflicting perspectives in current policy debates. Advocates of industrial policy emphasize its role in promoting innovation and technological upgrading, whereas critics stress its tendency to distort markets and generate unfair competition. Both views capture important aspects of reality. The apparent contradiction arises because they often focus on different stages of industrial development. Subsidies that are welfare-enhancing during an industry’s infancy may become welfare-reducing after the industry has matured. Recognizing this dynamic evolution provides a more coherent framework for evaluating industrial policy than treating all subsidies as either inherently beneficial or inherently harmful.
From this perspective, the appropriate question is not whether governments should subsidize industries, but whether a particular subsidy remains economically justified given the industry’s stage of development. Industrial policy should therefore be judged by its ability to facilitate industrial upgrading while minimizing long-run distortions. A well-designed subsidy is temporary, targeted, and responsive to changing economic conditions rather than permanent or unconditional.
Consumer versus Producer Subsidies
The form of government support is as important as its magnitude. Governments can subsidize either consumers or producers, and although both instruments can help address market failures, they operate through different economic mechanisms and have distinct implications for innovation, market development, and international competition. Understanding these differences is essential for designing industrial policies that promote innovation while minimizing trade distortions.
Consumer subsidies reduce the purchase price paid by buyers through tax credits, rebates, or direct grants. By stimulating demand, they encourage firms to expand production, move more rapidly down the learning curve, and exploit economies of scale. Demand-side support is particularly effective when the principal obstacle to industrial development is insufficient market adoption rather than inadequate production capacity.
Consumer subsidies are especially valuable in industries characterized by network externalities. Electric vehicles again illustrate the point. Consumers may be reluctant to purchase EVs until charging infrastructure becomes widely available, while private investors may hesitate to build charging stations until EV ownership reaches a sufficient scale. By encouraging early adoption, consumer subsidies help overcome this coordination problem and enable the market to reach a self-sustaining equilibrium.
From the perspective of international trade, consumer subsidies are generally less distortionary than producer subsidies. If they are available on equal terms to both domestic and imported products that satisfy the same eligibility requirements, they do not directly discriminate among producers. Firms continue to compete primarily on the basis of product quality, technological performance, and production efficiency rather than unequal government support. Consequently, consumer subsidies are less likely to generate accusations of unfair competition.
Nevertheless, consumer subsidies also have important limitations. Their effects are largely confined to the domestic market, because governments can subsidize purchases made by their own residents but have little ability to influence demand abroad. Moreover, eligibility criteria based on specific technical characteristics may unintentionally encourage firms to design products to maximize access to subsidies rather than to improve overall economic efficiency. Consumer subsidies may also become fiscally costly if they are maintained after technologies have become widely competitive.
Producer subsidies operate through a different channel. Rather than stimulating demand, they directly reduce firms’ production costs through grants, tax incentives, concessional loans, subsidized land, or support for research and development. These measures are particularly valuable when firms face financing constraints or when innovation requires substantial up-front investments with highly uncertain returns. By lowering the cost of experimentation and investment, producer subsidies can accelerate technological progress and strengthen long-term industrial capabilities.
Producer subsidies are therefore often better suited to promoting innovation than consumer subsidies. They encourage firms to invest in advanced manufacturing equipment, improve production processes, and undertake risky research projects whose social returns may substantially exceed their private returns. Such investments are especially important during the early stages of technological development, when uncertainty is greatest and private financing is most limited.
The same characteristics that make producer subsidies effective in fostering innovation also make them more likely to distort international competition. Because they directly lower production costs, producer subsidies may allow firms to compete successfully for reasons unrelated to productivity or technological superiority. If governments continue to support industries that have already become commercially mature, subsidized firms may expand exports on the basis of fiscal transfers rather than genuine comparative advantage. Such policies are more likely to depress world prices, encourage overcapacity, and provoke countervailing measures by trading partners.
The distinction between consumer and producer subsidies reinforces the dynamic framework developed in the previous section. During the infancy of an industry, both forms of support may be justified because they address different market failures. Consumer subsidies stimulate demand and facilitate market adoption, while producer subsidies encourage innovation and help firms overcome financing constraints. As industries mature, however, the justification for both forms of support diminishes. Consumer subsidies should gradually be withdrawn once network externalities have largely disappeared, while producer subsidies should be limited to activities that continue to generate substantial knowledge spillovers, such as basic research and pre-commercial technological development.
Accordingly, policymakers should focus not only on whether subsidies are provided but also on selecting the policy instrument most closely aligned with the underlying market failure. A subsidy that is well targeted, temporary, and proportionate to the problem it addresses is more likely to enhance social welfare than one that is broad, permanent, or poorly designed. In this sense, the effectiveness of industrial policy depends as much on policy design as on the scale of government intervention.
Trade Arrangements to Safeguard Fair Competition
The preceding analysis suggests that industrial subsidies should not be evaluated solely on the basis of their existence. Temporary subsidies that enable infant industries to overcome market failures may enhance both national and global welfare, whereas prolonged subsidies for commercially mature industries may distort competition and reduce economic efficiency. The central challenge for the international trading system is therefore to distinguish between these two types of government intervention.
Existing WTO rules provide an important framework for disciplining subsidies, but they have become increasingly difficult to apply in an era of widespread industrial policy. Governments across both advanced and emerging economies now subsidize strategic sectors, including semiconductors, batteries, renewable energy, and electric vehicles. The policy issue is no longer whether governments intervene in markets, but whether the scale and persistence of such intervention confer an unfair competitive advantage.
From this perspective, the objective of international trade rules should not be to eliminate industrial policy, but to preserve competitive neutrality while allowing governments sufficient flexibility to address genuine market failures. Trade rules should therefore distinguish between subsidies that promote innovation and long-term productivity growth and those that merely shift production across countries by artificially lowering production costs.
When producer subsidies exceed what is economically justified and cannot be reduced through negotiation, their competitive effects should be neutralized. One approach is to impose a compensating tariff equal to the excessive subsidy received by exporters. Unlike a conventional protective tariff, the purpose of such a measure is not to shield domestic producers from legitimate competition but to restore a level playing field by offsetting the artificial cost advantage created by excessive government support.
The compensating adjustment should reflect the difference between the producer subsidies available to exporters and those received by competing firms in the importing country. If firms in both countries receive broadly comparable support, little or no adjustment would be necessary. Conversely, if exporters benefit from substantially greater producer subsidies, the adjustment should offset only the excess advantage rather than the entire subsidy. Such an approach recognizes the growing reality that industrial policy has become common across countries, while seeking to ensure that competition remains based primarily on productivity, innovation, and efficiency.
An important institutional question concerns which government should implement such an adjustment. Under current WTO practice, importing countries may impose countervailing duties after determining that foreign subsidies have caused material injury to domestic industries. While this mechanism serves an important purpose, importing governments also face strong political incentives to provide additional protection for domestic producers. The combination of political pressure and tariff revenue may encourage duties that exceed what is necessary to neutralize the effects of foreign subsidies.
This essay therefore proposes that, wherever practicable, the exporting country should impose an export tariff equivalent to the excessive portion of the producer subsidy. Although this proposal differs from current practice, it offers several important advantages. From an economic perspective, consumers and producers in the importing country are largely indifferent as to which government collects the tariff revenue. In either case, the effective export price rises by approximately the same amount, thereby neutralizing the artificial competitive advantage created by excessive subsidies. The distribution of tariff revenue differs, but the impact on market competition is broadly similar.
The incentive structures facing governments, however, are fundamentally different. When the importing country imposes the tariff, it benefits both from protecting domestic producers and from collecting tariff revenue, creating incentives for excessive trade restrictions. By contrast, an exporting country that levies an export tariff receives the tariff revenue but simultaneously bears the cost of reduced export competitiveness. These opposing incentives are more likely to encourage moderation and reduce the risk of protectionist abuse.
Implementing such a system would require an independent institution capable of measuring government support in a transparent and internationally accepted manner. Estimating subsidy levels is inherently challenging because government assistance takes many forms, including direct grants, tax preferences, concessional loans, subsidized land, preferential procurement policies, publicly funded research, and other indirect forms of support. Disagreements over valuation have often complicated the application of existing subsidy rules.
The WTO is well positioned to perform this role. Building on its existing responsibilities under the Agreement on Subsidies and Countervailing Measures, it could establish an independent technical body responsible for evaluating subsidy programs, estimating their economic value, distinguishing between temporary and persistent support, and assessing whether an industry has moved beyond the infant stage. On the basis of these technical assessments, the WTO could recommend compensating export tariffs designed to offset only the excessive portion of producer subsidies.
Such a mechanism would offer several advantages. First, it would enhance transparency by establishing internationally accepted methodologies for measuring subsidies. Second, it would reduce the scope for politically motivated trade remedies by placing technical assessments in the hands of an independent body rather than national authorities. Third, it would preserve governments’ ability to pursue legitimate industrial policies aimed at promoting innovation while limiting distortions once industries have reached commercial maturity. Finally, because excessive subsidies would ultimately be neutralized through internationally recognized adjustment measures, governments would have stronger incentives to phase out support once its economic rationale had disappeared.
The proposed framework is therefore intended not to discourage industrial policy but to improve its governance. It recognizes that government intervention can enhance global welfare when it corrects identifiable market failures, while also acknowledging that prolonged subsidies can undermine fair competition and weaken confidence in the multilateral trading system. By distinguishing between these two situations, international trade rules can better balance the objectives of innovation, economic efficiency, and competitive neutrality.
Reconciling Industrial Policy and Open Trade
Industrial policy has once again become a defining feature of the global economy. China, the United States, the European Union, and many other economies increasingly rely on industrial subsidies to strengthen technological capabilities, promote strategic industries, and accelerate the transition to a low-carbon economy. The widespread resurgence of industrial policy reflects the presence of significant market failures, including learning-by-doing, knowledge spillovers, network externalities, financing constraints, and environmental externalities.
This essay argues that the economic justification for industrial subsidies is fundamentally dynamic. During the early stages of industrial development, temporary government support can accelerate innovation, reduce production costs, and generate substantial long-term social benefits. As industries mature, however, the rationale for broad-based subsidies progressively weakens. Continued support may encourage excessive investment, create overcapacity, distort international competition, and ultimately reduce global welfare. Effective industrial policy therefore requires not only well-designed interventions but also credible mechanisms for phasing them out once their original objectives have been achieved.
The article further argues that international trade rules should evolve to reflect this dynamic perspective. Rather than treating all subsidies as equally problematic, the multilateral trading system should distinguish between welfare-enhancing subsidies that address genuine market failures and persistent subsidies that merely confer artificial competitive advantages. Excessive producer subsidies should be neutralized through compensating adjustments based on differences in subsidy levels across trading partners. To reduce protectionist incentives and improve policy credibility, such adjustments should, wherever feasible, be implemented by exporting countries under the supervision of an independent WTO mechanism responsible for assessing subsidy levels and determining appropriate corrective measures.
Industrial policy and an open trading system need not be viewed as conflicting objectives. When industrial subsidies are carefully targeted, temporary, and designed to address clearly identified market failures, they can complement rather than undermine a rules-based international trading system. At the same time, transparent multilateral disciplines are essential to ensure that government support does not evolve into a source of persistent market distortion. A trading system capable of distinguishing between necessary and excessive subsidies would better promote innovation, reduce trade tensions, and enhance global economic welfare.
