Why India’s States Cannot All Follow the Same Development Model
A development strategy can be successful in one State and still become the wrong template for another.
States do not begin from the same place. They differ in human capital, geography, industrial structure, migration patterns, demography and institutional capacity. More importantly, the choices a State makes in response to those conditions reshape the economy that comes next.
This creates a problem with the way Indian development is often discussed. States are compared as though they were competing versions of the same model: one has higher income, another has better social indicators, another attracts more investment. The comparison is useful, but the assumption beneath it is not.
India does not have one State-development model waiting to be replicated.
It has several.
Each creates its own strengths, constraints and second-stage problems.
Development is not a formula
The temptation to search for a universal formula is understandable.
If one State combines strong education with industrialisation, another has high human development alongside migration and remittances, and a third builds rapid growth around modern services, it is easy to treat their outcomes as evidence for a single recipe.
But development does not work like a recipe.
The starting conditions matter. A State with a large pool of educated workers can pursue a different economic strategy from one where basic human-capital gaps remain substantial. A State with an established manufacturing ecosystem can build on supplier networks that another State does not possess. A State with a large overseas migrant population can receive an economic contribution from remittances that cannot simply be reproduced through a policy announcement.
The same policy can therefore produce different results across States. Policy operates through an existing economic and social structure; it does not operate on a blank sheet of paper.
The more useful question is not which State has discovered the perfect model. It is how different States built different combinations of capabilities—and what those combinations now demand from them.
Tamil Nadu shows why success changes the problem
Tamil Nadu is a useful illustration because its development story combines economic growth with unusually broad social investment.
Successive governments built infrastructure while expanding access to health and education. Higher education was deliberately widened beyond traditional elite access. Its industrial structure was built through interaction between large-scale investment and a wide base of smaller firms.
Large manufacturers brought capital, technology and access to wider markets, while MSMEs provided local production capacity and employment across different parts of the State. This helped connect industrial expansion with a broader network of skills, firms and workers rather than concentrating all the gains of manufacturing within a few large enterprises.
That structure mattered for the development model that followed. Growth was not treated simply as an increase in industrial output; it was also expected to expand productive capabilities and employment across the State.
For a long period, this produced a distinctive development structure.
But once a State reaches a higher level of human development and industrialisation, the problem changes.
The question is no longer simply how to attract capital.
It becomes: what kind of growth is the new capital creating?
Tamil Nadu’s recent experience makes that distinction visible. Between 2021 and 2025, announced investments reached ₹6.80 lakh crore, while completed investments stood at ₹1.57 lakh crore, a completion ratio of 23.09%. The Annual Survey of Industries also records a ratio of workers to gross capital formation of 0.58 for Tamil Nadu, compared with 0.34 for Gujarat and 0.33 for Maharashtra. The latest Annual Survey of Industries continues to show Tamil Nadu as a major manufacturing State, recording 15.02% of India’s operating factories and 15.24% of persons engaged in 2023-24.
These numbers do not mean that investment has stopped generating employment. They point to something narrower: the relationship between capital formation and job creation is changing.
Capital is becoming more important to production, while the employment generated by each additional unit of investment can become smaller.
That matters for a State whose earlier development model depended heavily on connecting industrial growth with employment.
The pressure is visible among smaller firms as well. Traditional labour-intensive clusters have faced repeated shocks, while new factories have not always developed strong linkages with existing MSMEs. Rising contractualisation, weaker wage shares and skill gaps add another layer to the problem.
This does not mean Tamil Nadu’s development model has failed.
It means that the success of one phase of development can alter the conditions under which the next phase must operate.
The State that once needed to expand access to education and attract manufacturing now faces a harder problem: how to translate higher skills, larger investments and greater industrial sophistication into sufficiently broad employment and productivity gains.
Development has moved to its next stage.
Kerala illustrates a different route
Kerala demonstrates why even States with broadly comparable social outcomes cannot simply be placed inside the same economic model.
Its development path has been strongly associated with human development, migration and remittances. Social investment has helped produce high levels of education and health outcomes, while migration has become an important part of the relationship between Kerala’s households and the wider economy.
That creates a very different economic structure from a manufacturing-led State.
Human development creates capabilities. What happens with those capabilities depends on the economic structure available to absorb them.
In Kerala’s case, migration became an important mechanism connecting human capital to employment and income outside the State. That helped households and the broader economy, but it also means that Kerala’s development story cannot simply be reproduced in a State without the same migration networks, skills or demographic conditions.
The fiscal side reveals another feature of this model.
Kerala has a high burden of committed expenditure, including salaries, pensions and interest payments. RBI’s State Finances publications provide comparable State-level evidence on revenue expenditure, salaries, pensions, interest payments and capital expenditure, reinforcing the fiscal dimension of this trade-off. But interpreting that number simply as evidence of inefficient spending would miss part of the story. Public expenditure on salaries and social services is also connected to the institutional architecture through which Kerala built its social-development outcomes.
Kerala’s fiscal tension therefore has two sides. The expenditure commitments that now reduce room for manoeuvre are also linked to the public institutions through which the State accumulated its human-development gains. Salaries, pensions and social-sector spending cannot be understood only as items competing with capital expenditure; they are also part of the institutional legacy of the development path Kerala chose.
The fiscal challenge emerges when that legacy has to be maintained while the State simultaneously needs new resources for investment and a changing demographic structure.
That is not a uniquely Kerala problem. Institutions created to solve yesterday’s problems can become constraints when the structure of the economy changes.
Telangana shows what a different growth structure looks like
Telangana presents a different problem because the composition of growth matters as much as its pace.
Its expansion has increasingly been driven by services, with real estate and IT, together with trade, hotels and restaurants, accounting for a large share of services output. Relative to Andhra Pradesh, the State’s services sector rose from about 1.25 times the corresponding sector in 2013-14 to 1.47 times by 2024-25.
The implications become clearer when the sectoral story is viewed alongside the geography of production. Rangareddy recorded GDDP of ₹2,83,419 crore in 2022-23 and Hyderabad ₹2,28,623 crore, reflecting the scale of the metropolitan economy.
This concentration gives Telangana a powerful growth engine, but it also means that the State’s development pressures differ from those of a manufacturing-led economy.
Manufacturing-led growth creates one set of questions around supplier networks, labour absorption and industrial employment. A metropolitan service economy raises another set around concentration, housing, infrastructure and the spread of opportunity.
The difference is not simply between two sectors; it is between two economic structures that generate different policy problems.
Neither is automatically superior.
They are different economic structures.
Why copying the visible outcome misses the mechanism
This is where State comparisons can become misleading.
Suppose one State has higher income and another has better human-development outcomes. It is tempting to identify the policies associated with those outcomes and recommend that other States adopt them.
But policies travel more easily than the conditions that made them effective.
An industrial policy works differently where supplier ecosystems already exist.
An education expansion works differently where the labour market can absorb newly educated workers.
A migration-based income model cannot simply be legislated into existence.
A metropolitan services strategy cannot be detached from the infrastructure, skills and urban economy that support it.
The important unit of analysis is therefore not the policy by itself. It is the interaction between initial conditions, institutions and economic structure.
That interaction produces the development trajectory. Once the trajectory is established, it also shapes the State’s future choices.
A State’s past development creates its next set of constraints.
Development models create second-stage problems
This is perhaps the least appreciated part of the story.
Development is usually described as a movement from problems to solutions: low education to higher education, weak industry to stronger industry, high fertility to demographic transition, low income to higher income.
But successful development does not eliminate constraints.
It changes them.
A State that expands education creates a more educated population with higher expectations. If the economy does not create enough suitable employment, the success of education can coexist with frustration in the labour market.
A State that builds extensive public services creates a stronger social foundation. But those systems require continuing fiscal commitments.
A State that becomes a services hub creates productivity and investment. Economic activity can also become concentrated around the sectors and places that generate the highest returns.
A State that attracts sophisticated capital may therefore discover that the old employment relationships between investment, local firms and workers no longer operate in the same way.
These are not signs that development has stopped.
They are signs that the development problem has changed.
The deeper federal lesson
This has an important implication for how India thinks about development across States.
A national development strategy necessarily needs national objectives. But implementation cannot assume that every State is moving through the same stage of development or possesses the same economic structure.
The appropriate question is not whether every State should reach the same destination through the same route.
It is whether each State has the institutional capacity and policy space to respond to the particular structure it has built.
That is especially important because State development is cumulative.
Human capital affects industrial possibilities.
Industrial structure affects employment.
Employment affects migration and household income.
Demographic change alters the future labour force.
Fiscal capacity determines how much a State can continue investing in public services and infrastructure.
Each element changes the conditions for the next.
The result is a system in which State trajectories diverge over time even when they operate within the same national economy.
India is not a collection of identical laboratories
The real mistake, then, is not comparing States.
Comparison is valuable.
The mistake is treating the comparison as if it were a search for a single winner whose model can simply be copied everywhere else.
Tamil Nadu’s experience shows how a broad social-development and manufacturing strategy can eventually confront a harder employment problem as capital intensity rises.
Kerala shows how human development, public services and migration can combine into a distinct economic structure—with strengths that are difficult to reproduce and fiscal pressures that emerge from the same institutional architecture.
Telangana shows how a rapidly expanding service economy can produce a different growth trajectory altogether.
These are not three versions of the same story.
They are three demonstrations of the same principle.
Development is path-dependent.
What a State can do today depends partly on what it built yesterday. And what it builds today determines the constraints it will face tomorrow.
That is why India’s States cannot all follow the same development model.
The objective of development policy should not be to make every State look alike. It should be to understand the economic structure each State has created well enough to know which problems belong to its current stage—and which solutions would only work somewhere else.
