Structural transformation: the textbook pattern and India's peculiar path to 1990
Sectors of the Indian Economy · section 5 of 10
In this note
Detail
1. What "structural transformation" means
- Structural transformation is the shift of output and jobs from agriculture to industry, and then to services, as a country develops.
- It is measured in two ways. Always check both:
- Output share: a sector's share in GDP or GVA (gross value added, which is the value of output minus the value of inputs used up).
-
Employment share: a sector's share in total workers. This is the occupational structure, meaning how workers are spread across sectors.
-
Formula:
- Sector share (%) = (Sector's GDP or GVA ÷ Total GDP or GVA) × 100
-
Workforce share (%) = (Workers in the sector ÷ Total workers) × 100
-
Worked example: Total GDP = ₹100 crore and agriculture = ₹35 crore. So agriculture's GDP share = 35%. If agriculture also holds 67 of every 100 workers, its workforce share = 67%. That gap is the sign of a problem, as shown in the sections below.
- Three sectors (the NCERT classification):
- Primary: uses natural resources directly. Examples: farming, dairy, fishing, forestry, mining.
- Secondary: changes natural products into other forms through manufacturing. Also called the industrial sector.
- Tertiary: activities that help the other two sectors, such as transport, storage, banking, trade and communication. Also called the service sector.
2. The developed-country sequence (Class 10, "Historical Change in Sectors")
-
Early stage: - The primary sector is the biggest in both production and employment.
-
Farm surplus stage: - Better farming methods produce more food than before. - Fewer people are needed on farms. The people who are freed can work as craftspersons, traders, transporters, administrators and soldiers. - Most goods are still natural products, and most people still farm.
-
Industrial stage (over 100+ years): - New ways of manufacturing bring factories. - Farm workers move into factories. They were often "forced" to move (see the NCERT history chapters on industrialisation). - The secondary sector becomes the largest in both output and jobs.
-
Service stage (last 100 years): - The tertiary sector becomes the largest in output. - Most workers are in services too.
- Key point: in this sequence, output and jobs move together. When a sector's GDP share rises, its job share also rises.
3. Theories behind the pattern (Beyond NCERT)
- Fisher-Clark three-sector hypothesis:
- Named after A.G.B. Fisher and Colin Clark.
-
As incomes rise, labour and output move from the primary sector to the secondary sector and then to the tertiary sector.
-
Dual economy:
- Here a modern sector exists side by side with a traditional sector.
- The modern sector is capital-intensive (it uses many machines) and highly productive.
-
The traditional sector is farming or informal work with low productivity.
-
Lewis model (1954):
- Farms have surplus labour, meaning workers who can leave without reducing farm output.
- These workers move to the modern sector. Growth continues until the surplus is used up.
-
Full treatment is in growth-theories-business-cycles.
-
Disguised unemployment:
- More people work on a farm than are actually needed. If some leave, output does not fall.
- Class 10 example: a family of 5 works on a plot that needs only 2 workers.
- This is the "surplus labour" of the Lewis model.
4. India's colonial baseline (Class 11, §1.7)
- The occupational structure was stagnant. It barely changed during British rule.
- Agriculture: 70-75% of workers
- Manufacturing: about 10%
-
Services: 15-20%
-
Regional variation:
- Agriculture's share fell a little in parts of Madras Presidency, Bombay Presidency and Bengal, because manufacturing and services grew there.
-
Agriculture's share rose in Orissa, Rajasthan and Punjab.
-
Result: India began planning in 1950-51 with most workers on farms and a very small factory base.
5. 1950-1990: the numbers (Class 11, Indian Economy 1950-1990)
| Share (%) | GDP 1950-51 | GDP 1990-91 | Change | Workforce 1950-51 | Workforce 1990-91 | Change |
|---|---|---|---|---|---|---|
| Agriculture | 59.0 | 34.9 | −24.1 | 72.1 | 66.8 | −5.3 |
| Industry | 13.0 | 24.6 | +11.6 | 10.7 | 12.7 | +2.0 |
| Services | 28.0 | 40.5 | +12.5 | 17.2 | 20.5 | +3.3 |
- Read the "Change" columns: agriculture lost 24.1 points of GDP share but only 5.3 points of workforce share. So output left the farms, but people stayed on them.
Worked example: relative labour productivity
- Formula: Relative productivity = GDP share ÷ Workforce share
- A value above 1 means a worker in that sector produces more than the average worker.
-
A value below 1 means the worker produces less than the average.
-
Agriculture:
- 1950-51: 59.0 ÷ 72.1 = 0.82
-
1990-91: 34.9 ÷ 66.8 = 0.52
-
Industry:
- 1950-51: 13.0 ÷ 10.7 = 1.21
-
1990-91: 24.6 ÷ 12.7 = 1.94
-
Services:
- 1950-51: 28.0 ÷ 17.2 = 1.63
-
1990-91: 40.5 ÷ 20.5 = 1.98
-
Meaning:
- By 1990-91, a farm worker produced about half the output of the average worker.
- A worker in industry or services produced about 2 times the average, which is nearly 4 times a farm worker.
- The dual economy gap became wider between 1950-51 and 1990-91.
6. Industry, 1950-1990
- Industry grew at about 6% a year.
- It diversified beyond cotton textiles and jute, mostly through the public sector (industries owned by the government).
- NCERT calls industry's rising GDP share "an important indicator of development".
- But industry's workforce share rose only from 10.7% to 12.7%. Most of this industry was capital-intensive, so it added output faster than jobs.
7. Box 2.4, "The Service Sector": the "peculiar" path
- By 1990, services were 40.59% of GDP (the table shows 40.5). This was more than agriculture or industry, "like what we find in developed nations".
- Why NCERT calls this "peculiar":
- In developed countries, industry became the largest sector first, and services came later.
-
In India, services became the largest sector before industry ever dominated. India skipped the factory-led stage.
-
The shift to services accelerated after 1991, because of globalisation (the opening of India's economy to world trade and investment).
- Beyond NCERT: premature deindustrialisation. This means manufacturing's share begins to fall, or stops rising, at a much lower income level than it did in today's rich countries. India's services-first path is often discussed under this idea.
8. The failure: jobs did not follow output
- Agriculture's GDP share fell sharply, but the share of people who depended on it barely moved.
- Industry and services did not absorb the farm labour.
- Many economists call this an important policy failure of 1950-1990.
- The chain of cause and effect:
- Industry used many machines and few workers → few new factory jobs
- Farm population kept growing → more disguised unemployment on small plots
- Farm incomes stayed low → rural poverty stayed high
9. NCERT inconsistency: flag this in answers
- The same chapter's text says the population depending on agriculture fell from 67.5% (1950) to 64.9% (1990). It also speaks of "65 per cent" in 1990.
- The chapter's own table shows 72.1% → 66.8%.
- Rule: quote the table for workforce shares, and mention the mismatch. Box 2.4's 40.59% and the table's 40.5% differ only because of rounding.
10. Where the path stands now (2017-18 to 2023-24)
- Agriculture's workforce share is rising again:
- It rose from 44.1% (2017-18) to 46.1% (2023-24) (PLFS) [2].
-
Compare this with 66.8% in 1990-91 (NCERT table). The share has fallen over the long run, but the fall has reversed since 2017-18. PLFS and the older NCERT data use different survey methods, so treat this long-run comparison as a rough guide.
-
Industry and services lost job share (2017-18 → 2023-24):
- Manufacturing fell from 12.1% to 11.4% of workers [2].
- Services fell from 31.1% to 29.7% [2].
-
Construction employed 12% of the workforce (2023-24) [2].
-
Gender pattern (2017-18 → 2023-24):
- The share of female workers in agriculture rose from 57.0% to 64.4% [2].
- The share of male workers in agriculture fell from 40.2% to 36.3% [2].
-
In rural areas, the female share in agriculture rose from 73.2% to 76.9% [2].
-
The output-job gap continues in services:
- Services give over 50% of GVA but only about 30% of jobs (2023-24) [3].
- Services added nearly 40 million jobs over the past six years [3].
-
This is the 1990 "peculiar" pattern (Box 2.4), still visible.
-
International comparison (World Bank data, cited by NITI Aayog):
- India's services share of employment rose from 22.1% (1992) to 31.0% (2022), a rise of only 8.9 percentage points [3].
-
The world's services share of employment rose from 35.5% to 49.8% over the same period [3].
-
Job need: the economy must create about 78.5 lakh non-farm jobs every year until 2030. This will speed up the "structural transformation from farm to non-farm jobs" (Economic Survey 2024-25) [2].
- Policy response, the National Mission on Manufacturing (Union Budget 2025-26):
- Target: raise manufacturing's share of GDP from 12.9% (2023) to 25% by 2035 [4].
- Target: create 143 million jobs [4].
-
This is an attempt to build the factory stage that India skipped.
-
Labour-market backdrop (PLFS, July 2023-June 2024, age 15+, usual status):
- LFPR (labour force participation rate: the share of people who are working or looking for work) was 60.1% [5].
- WPR (worker population ratio: the share of people who are actually working) was 58.2% [5].
- The unemployment rate was 3.2% [5].
- Female LFPR rose from 37.0% (2022-23) to 41.7% (2023-24) [5].
- Much of this new female work is in agriculture, as the gender figures above show [2].
Prelims Hooks
- Fisher-Clark hypothesis: as a country develops, output and labour move from the primary sector to the secondary and then to the tertiary sector.
- Colonial occupational structure: agriculture 70-75%, manufacturing about 10%, services 15-20%. It was stagnant.
- Trap: during colonial rule, agriculture's workforce share rose in Orissa, Rajasthan and Punjab. It fell in parts of Madras, Bombay and Bengal.
- 1990-91 (NCERT table): services 40.5% of GDP (Box 2.4: 40.59%) was the largest sector, but only 20.5% of the workforce. Agriculture had 34.9% of GDP and 66.8% of the workforce.
- "Peculiar" (Box 2.4): in India, services became the largest sector before industry ever dominated.
- Trap: the NCERT text says 67.5% → 64.9% of the population depended on agriculture. The NCERT table shows workforce share 72.1% → 66.8% (1950-51 to 1990-91).
- PLFS 2023-24: agriculture's workforce share rose from 44.1% (2017-18) to 46.1%. Manufacturing fell from 12.1% to 11.4% [2].
- Services (2023-24): over 50% of GVA but about 30% of jobs [3].
- National Mission on Manufacturing (Budget 2025-26): manufacturing to 25% of GDP by 2035, up from 12.9% (2023) [4].
- Lewis model (1954): surplus farm labour, which is disguised unemployment, moves to the modern sector.
Mains Points
- Growth without job shift:
- From 1950-51 to 1990-91, agriculture lost 24.1 points of GDP share but only 5.3 points of workforce share.
- Farm workers' relative productivity fell from 0.82 to 0.52.
-
Use this to explain rural poverty, disguised unemployment and the dual economy. It is NCERT's "important policy failure".
-
Services-led vs manufacturing-led paths:
- India skipped the factory stage.
- Services give high output but few jobs: over 50% of GVA against about 30% of jobs [3].
-
Services need skills, while manufacturing can absorb low-skill farm labour. Link this to Make in India, PLI schemes and the National Mission on Manufacturing target of 25% of GDP [4].
-
Reversal after 2017-18:
- Agriculture's job share rose to 46.1%, and female workers moved towards farms (64.4%) [2].
- This may be "distress" absorption (people taking farm work because there are no other jobs), not progress.
-
Argue for labour-intensive manufacturing, construction, and rural non-farm jobs (78.5 lakh a year needed until 2030) [2].
-
Policy lesson from 1950-1990:
- The capital-intensive, public-sector-led industrialisation of this period raised output but not employment.
- Use this in GS-III answers on inclusive growth and on choosing technology that creates jobs.
