**Introduction** Concentrating industrial policy support in selected sectors can accelerate domestic capacity building and strengthen targeted industries. Over time, however, sustained and narrowly focused support can generate inefficiencies and structural dependency if it weakens competition, distorts investment decisions, or creates ongoing fiscal commitments. The long-term effects depend on program design, transparency, and credible limits on duration and scope[1][2]. **Long-term economic effects of concentrated industrial policy support** **1.** **Capital misallocation and reduced competition** Large volumes of public funding directed to a small number of sectors can shift investment away from underlying market demand. When capital allocation reflects policy priorities more than commercial viability, the likelihood of excess capacity, lower returns, and slower productivity growth increases[1]. Sustained support can also weaken competitive pressure. Firms that expect continued government support may expand output despite weak demand or continue operating despite poor performance. Over time, this can slow the reallocation of capital and labor toward more productive activities[1][2]. **2.** **Rising fiscal costs and subsidy competition** Sector-focused support often involves industry-specific infrastructure, workforce training, targeted financing, and regulatory changes. These measures can strengthen domestic production networks, but they can also increase reliance on ongoing public support. Reversing or scaling back support later can require significant public resources and administrative effort[1][3]. When several economies target the same strategic sectors, subsidy competition can intensify[3]. As governments increase support to match one another, public spending rises and resources may be redirected from other priorities. Economies with more limited fiscal capacity may find it difficult to sustain comparable levels of support[2]. **3.** **Trade distortions and excess capacity** Industrial policy frequently includes local content requirements or preferences for domestic suppliers. While intended to anchor production at home, these measures can reduce integration with competitive global suppliers and limit efficiency gains from specialization[6]. Gaps in subsidy notification and reporting make it harder to monitor support measures and address distortions[4]. When multiple governments concentrate support in the same sectors, excess capacity can develop across jurisdictions[3]. Even where resilience objectives are legitimate, this duplication can reduce overall global efficiency. **Conclusion** Concentrated industrial policy support can deliver near-term gains in targeted industries. Over time, however, sustained and narrowly focused intervention can lead to excess capacity, weaker competitive pressure, fiscal strain, and dependence on protected sectors. The risk of long-term inefficiency is lower when programs are transparent, time-limited, linked to clear performance criteria, and regularly reviewed. Without these safeguards, concentrated support can reduce the economy’s ability to adapt to technological change and shifts in comparative advantage.
