**Introduction** Industrial subsidies can deepen inequalities between advanced and developing economies by reinforcing differences in fiscal capacity, technological depth, and control over high-value production segments. Large-scale support programs in advanced economies increasingly shape where investment flows, where innovation clusters form, and which countries capture the most productive parts of global value chains. Developing economies with more limited fiscal and institutional capacity face growing constraints in competing for strategic industries, widening structural gaps in income and industrial capability. **How industrial subsidies widen gaps between advanced and developing economies** **1.** **Fiscal capacity asymmetry and subsidy scale** Advanced economies can fund industrial programs at levels that most developing economies cannot replicate. Multi-year fiscal commitments to semiconductors, clean energy manufacturing, and other technology-intensive sectors have reshaped investment incentives and influenced where production is located. Many developing economies, however, face tighter borrowing constraints and higher financing costs. Expanding subsidy programs on a comparable scale would increase debt risks or displace essential public spending. As subsidy competition intensifies, economies with limited fiscal space must either reduce participation in priority sectors or accept greater macroeconomic vulnerability[1][2]. This imbalance allows advanced economies to strengthen their position in capital- and technology-intensive industries. **2.** **Concentration of high-value technological ecosystems** Industrial subsidies often concentrate on frontier sectors with high research intensity and strong network effects. Sustained public support encourages the clustering of firms, research institutions, suppliers, and skilled labor in particular locations, reinforcing advantages in productivity and innovation over time. When high-value activities — such as design, advanced manufacturing, and intellectual property development — become concentrated in heavily subsidized economies, upgrading opportunities for developing economies become more limited. Participation in global production networks does not by itself lead to movement into higher-value segments without sustained domestic capability development[3]. Concentration driven by subsidy programs makes it more difficult for economies with smaller fiscal and technological bases to build comparable industrial ecosystems. **3.** **Market distortion, excess capacity, and competitive pressure** Large-scale subsidies shape global supply and pricing dynamics. When multiple advanced economies support the same strategic industries, production capacity can expand rapidly, especially in capital-intensive and scale-driven sectors. The resulting increase in supply may exert downward pressure on prices, placing unsubsidized producers at a competitive disadvantage. Industrial programs often reinforce these effects through local content requirements and preferential procurement provisions. Such measures restrict market access for exporters from developing economies and limit their ability to participate in higher-value stages of production[4]. Together, expanded capacity and selective market access contribute to a more fragmented competitive landscape in which smaller economies face enduring structural disadvantages. **4.** **Investment diversion and reshaping of value chains** Industrial subsidies reduce uncertainty and improve projected returns in the economies that provide them, shaping firms’ decisions about where to establish new production capacity. Foreign direct investment flows remain unevenly distributed, with advanced economies capturing a large share of high-technology and capital-intensive projects[5]. When subsidies are conditioned on domestic production or linked to strategic alignment, investment location decisions adjust accordingly. For developing economies pursuing industrial diversification, reduced access to advanced manufacturing investment constrains technology transfer, skills upgrading, and productivity growth. Continued diversion of high-value projects reinforces specialization patterns in which advanced economies strengthen their position in innovation-intensive sectors, while developing economies remain concentrated in lower-value segments of global production. **Conclusion** Industrial subsidies can widen global inequality when implemented at scales and in sectors that only advanced economies can sustain. Differences in fiscal capacity, concentration of technological ecosystems, market distortions, and investment diversion reinforce existing gaps in productivity and industrial capability. Without greater transparency, more disciplined subsidy design, and governance that accounts for development concerns, subsidy competition may entrench a two-tier global production structure and further constrain upgrading opportunities for developing economies.
