The Asian Development Bank (ADB) study When Manufacturing Matters Most: Structural Transformation and Productivity Growth Trajectories in Developing and Emerging Economies suggests that despite the rise of the digital economy, manufacturing remains the most powerful driver of labor productivity for developing nations.
Analysing data from 31 economies, including India over 60 years, the findings indicate that expanding manufacturing employment delivers nearly double the productivity benefits for slower-growing countries compared to high performers.
The research identifies a major "structural break" in 1982, after which expansion of manufacturing became a central driver of productivity growth, particularly in slower-growing economies.
While concerns about premature deindustrialisation persist, the findings suggest that economies maintaining a strong industrial base can achieve significantly higher productivity gains, with low-manufacturing economies potentially improving annual productivity growth by up to 3.4 percentage points.
Key Findings on Global Productivity Trajectories
The 1982 Shift: Before 1982, growth was mostly about moving people out of agriculture. Post-1982, manufacturing became the primary engine, while the expansion of the services sector contributed less to overall productivity growth.
The Catch-Up Mechanism: Slower-growing economies benefit the most from manufacturing. By adopting the manufacturing intensity and technology of top-tier nations, bottom-quartile countries could boost their growth by 2.7 percentage points.
Invisible Drivers: As economies mature, "unobservable" factors like Institutional Quality and Technological Capability become just as important as the number of factories built.
The Counterfactual Proof: The study shows that economies with low manufacturing levels have significant untapped growth potential. Increasing industrial employment toward levels seen in manufacturing-intensive economies could raise productivity growth by up to 3.4 percentage points annually. However, these gains depend on parallel improvements in institutional quality and technological capability.
Specific Context: India as a Global Benchmark
The ADB identifies India as a standout high-performer that achieved strong productivity growth during the post-1982 global economic shift. While many emerging markets struggled, India leveraged international integration and trade openness to achieve consistent productivity gains, similar to the "Asian Tigers" (South Korea, Taipei, China).
Top-Tier Performance: India is among the high-performing economies in the study, demonstrating how international integration and trade openness can facilitate technology transfers and specialisation, contributing to sustained productivity growth.
Manufacturing Resilience: Unlike regions that faced "premature deindustrialization," India managed to improve its manufacturing employment shares, which directly fueled its strong economic trajectory.
What is "Premature Deindustrialization"?
Premature Deindustrialization is a trend where an economy begins to lose its manufacturing jobs and share of GDP before it has become wealthy. It acts as a catalyst for Economic Stagnation because it shrinks the sector that traditionally provides high-paying jobs and technological innovation for unskilled workers.
This mechanism manifests as a transition from "productive factories" to "low-value services" (like basic retail or manual labor), making it harder for a country to reach high-income status. For Policy Makers, preventing this trend is a primary lever to benchmark a trajectory where the "Make in India" initiative ensures long-term prosperity.
Policy Relevance
Refines the Case for Industrial Subsidies: The ADB's evidence transforms "protectionist manufacturing support" into an Essential Growth Strategy, showing that factory jobs are the most efficient way to raise a nation's standard of living.
Challenges the "Service-Led" Growth Myth: The finding that services do not significantly drive productivity transforms "IT-centric planning" into a Balanced Economic Roadmap, where physical production is seen as the necessary foundation for digital wealth.
Institutional Quality Alongside Infrastructure: Since unobservable capabilities drive long-term returns, the report indicates that Improving Governance is just as vital as building industrial corridors to maximise productivity.
Regional Integration and Trade: India’s success as a benchmark transforms "closed-market thinking" into Strategic Openness, suggesting that exposure to global competition is what forces domestic industries to become more productive.
