Industrial Growth Trends

India’s industrial growth trajectory since independence is characterized by major shifts in state policy, structural transformations, and macroeconomic shocks. This evolution can be analyzed across four distinct chronological phases.

Phase I: The Era of Foundation and Heavy Industrialization (1951–1965)

This phase was characterized by state-led industrialization under the framework of the First, Second, and Third Five-Year Plans. Guided by the Mahalanobis Model, the primary focus was on establishing import-substituting, capital-intensive heavy industries (such as steel, machine tools, and heavy chemicals). During this period, industrial growth averaged a robust 7% to 8% per annum, driven by massive public sector capital expenditure.

Phase II: The Period of Structural Deceleration and Stagnation (1965–1980)

Industrial growth dropped to an average of less than 4% per annum. This prolonged stagnation was triggered by several structural bottlenecks:

• Consecutive severe droughts and agricultural distress that compressed rural consumer demand.
• External shocks, including the India-Pakistan wars of 1965 and 1971, and the global oil shocks of 1973 and 1979.
• Extreme regulatory tightening through the Monopolies and Restrictive Trade Practices (MRTP) Act of 1969 and the Foreign Exchange Regulation Act (FERA) of 1973, which institutionalized the “License-Permit Raj” and stifled private capital.

Phase III: Period of Partial Recovery and Deregulation (1980–1991)

The industrial sector witnessed a revival, with growth rates bouncing back to nearly 6% per annum. This recovery was fueled by initial, tentative steps toward internal liberalization under the governments of the 1980s. Reforms included the relaxation of industrial licensing, introduction of broad-banding of industries, and fiscal expansion financed by external borrowing, which ultimately proved unsustainable and triggered the 1991 Balance of Payments crisis.

Phase IV: The Post-Liberalization Era (1991–Present)

The rolling out of the New Industrial Policy (NIP) in 1991 dismantled the License Raj, removed investment caps under the MRTP Act, opened up sectors to Foreign Direct Investment (FDI), and initiated public sector disinvestment. This phase shifted the industrial ecosystem toward market-driven dynamics, causing structural volatility but leading to high growth phases (exceeding 8-9% annually) during the mid-2000s boom, followed by a transition toward high-technology and infrastructure-led growth in the mid-2020s.

Statistical Measurement of Industrial Growth

The tracking and quantitative assessment of industrial performance in India are managed through two primary statistical frameworks compiled by the Ministry of Statistics and Programme Implementation (MoSPI).

Index of Industrial Production (IIP)

The IIP is a short-term macroeconomic indicator that measures the monthly volume changes in the production of a selected basket of industrial products.

Sectoral Classification of IIP

The IIP divides the entire industrial sector into three broad structural components with distinct assigned weights based on the base year of 2011-12:

Use-Based Classification of IIP

To understand the economic destination of industrial outputs, the IIP is also cross-classified into six functional categories:

• Primary Goods (Weight: 34.05%): Basic raw materials like coal, crude oil, natural gas, and electricity used for further processing.
• Intermediate Goods (Weight: 17.22%): Semi-finished items required as inputs in further manufacturing (e.g., cotton yarn, plywood, electronics components).
• Infrastructure / Construction Goods (Weight: 12.34%): Materials vital for capital creation in building and infrastructure projects (e.g., steel, cement, bricks, cables).
• Capital Goods (Weight: 8.22%): Plant, machinery, and equipment used directly to manufacture other goods (indicative of the private investment cycle).
• Consumer Non-Durables (Weight: 15.33%): Fast-Moving Consumer Goods (FMCG) meant for immediate consumption (e.g., food products, medicines, apparel).
• Consumer Durables (Weight: 12.83%): High-value goods with a long utility life span (e.g., automobiles, white goods, electronic devices).

Annual Survey of Industries (ASI)

Unlike the quick monthly volume estimates of the IIP, the ASI is a comprehensive annual exercise that tracks the registered factory sector in India. It captures actual financial variables—such as Gross Value Added (GVA), profits, employment, emoluments, and capital formation. The ASI relies on accounting data from factories registered under the Factories Act, 1948, providing the baseline structural inputs required for compiling National Accounts and GDP calculations.

The Core Sector Framework

The Index of Eight Core Industries (ICI) measures the collective performance of eight foundational production sectors that act as infrastructural pillars for the broader economy.

Weight Distribution and Hierarchy

The core industries comprise 40.27% of the total weight of the items included in the overall Index of Industrial Production (IIP). The individual weights of these eight core sectors are distributed as follows:

Stagnant Share of Manufacturing in GDP

A defining paradox of India’s structural transformation is that while the services sector expanded exponentially post-1991, the share of the manufacturing sector in India’s Gross Value Added (GVA) remained stubbornly stagnant around 16% to 17% for nearly three decades. India bypassed the traditional transition from an agrarian economy to an industrial powerhouse, moving directly into a services-driven growth model.

Transition to Medium and High-Technology Production

As highlighted in modern macroeconomic indicators, a structural upgrade is underway within the manufacturing sector. Medium and high-technology manufacturing now accounts for approximately 46% of India’s total manufacturing value added. This shift reflects an advanced production structure away from low-value primary processing toward sophisticated domains like defense electronics, pharmaceuticals, aerospace engineering, and automobile assembly.

Recovery and Growth Dynamics

Following the global supply shocks of the early 2020s, India’s industrial sector demonstrated a robust structural recovery. The industrial sector recorded a growth rate of 7% in the first half of the 2025-26 fiscal year, outperforming the 6% expansion registered in the preceding year. This momentum was largely supported by resilient domestic consumption, strong public capital expenditure on transport infrastructure, and healthier balance sheets across commercial banks and corporate firms (resolving the historical Twin Balance Sheet problem).

Contemporary Policy Initiatives Driving Growth

Production Linked Incentive (PLI) Scheme

The PLI scheme is the government’s flagship intervention designed to scale up domestic manufacturing, enhance export capabilities, and position India as an integral hub in Global Value Chains (GVCs). It shifts the traditional policy focus from input subsidies to performance-linked cash incentives.

• Mechanism: The scheme offers an incentive ranging from 4% to 6% on incremental sales of goods manufactured in India over a designated base year.
• Coverage: It spans 14 champion sectors, including Mobile Manufacturing and Specified Electronic Components, Critical Key Starting Materials (KSMs)/Drug Intermediates, Medical Devices, Automobiles and Auto Components, Advanced Chemistry Cell (ACC) Batteries, and Specialty Steel.

PM GatiShakti National Master Plan

Launched as a digital public platform, PM GatiShakti integrates the geospatial planning of 16 ministries (including Railways, Highways, Shipping, and Power) into a single map repository. It breaks down departmental silos to ensure synchronized, multi-modal connectivity, directly reducing the domestic logistics cost burden from 13-14% of GDP toward a globally competitive single-digit level.

National Manufacturing Policy and NIMZs

The policy aims to increase the share of manufacturing in GDP to 25% and create 100 million jobs. A primary tool under this framework is the establishment of National Investment and Manufacturing Zones (NIMZs)—massive, self-governing industrial townships featuring state-of-the-art infrastructure, clean technologies, and simplified regulatory compliances.

National Industrial Corridor Development Programme

This program focuses on developing integrated industrial corridors across the country, leveraging Dedicated Freight Corridors (DFCs) to establish high-velocity manufacturing zones. Prominent corridors include the Delhi-Mumbai Industrial Corridor (DMIC) and the Amritsar-Kolkata Industrial Corridor (AKIC), designed to promote balanced regional development.

Key Challenges Inhibiting Full Potential

Underinvestment in Research and Development (R&D)

India’s national expenditure on R&D stands stagnant at a modest 0.64% of GDP, which is significantly lower than advanced industrial economies or peers like China. Furthermore, the private business sector contributes only about 41% to total R&D spending, shifting the burden onto public institutions and limiting cutting-edge industrial innovation.

Missing Middle in the MSME Sector

India’s industrial structure suffers from a sharp polarization: a vast number of micro and informal enterprises that cannot scale up due to credit and technology bottlenecks, and a few massive capital-intensive conglomerates. The “missing middle”—healthy, mid-sized manufacturing corporations capable of driving mass employment and participating extensively in international supply chains—remains thin.

High Logistics and Energy Input Costs

Despite infrastructure upgrades, Indian manufacturers face higher logistics overheads and industrial power tariffs compared to competitors in Vietnam, Bangladesh, and China. This hampers cost competitiveness in low-margin, labor-intensive export markets like textiles and leather.

UPSC Prelims Trivia and Fact Check

Base Year Revisions

To ensure statistical tracking accurately mirrors modern industrial shifts, MoSPI updates the base years of macroeconomic indices periodically. The new series of IIP and GDP is transitioning to a updated base year of 2022-23 to incorporate new industrial items (like green energy equipment and digital electronics) and drop obsolete items.

Core Sector Lead Indicator

Because the Index of Eight Core Industries is released on the last working day of every month—nearly two weeks ahead of the complete IIP release—it serves as a critical lead economic indicator used by analysts to predict the directional momentum of the overall industrial sector.

Use of Double Deflation Methodology

To align national accounting with global standards, India’s statistical agencies are moving toward a double deflation methodology for calculating manufacturing GVA. This involves deflating the value of gross output by an output price index and the value of intermediate inputs by an input price index separately, preventing artificial inflation of industrial productivity numbers when input costs drop sharply.
