Factors Influencing Economic Development: Economic and Non-Economic Determinants

Some countries turn a single generation of hard work into decades of rising incomes, better hospitals, and modern cities. Others, despite similar starting points, stay stuck. Economists have long tried to explain this gap, and the answer usually comes down to a mix of measurable economic inputs and softer, harder-to-quantify social and political conditions. Together, these are called the determinants of economic development, and understanding them explains why some economies sprint ahead while others struggle to find momentum.

Two broad categories of determinants 🔗

Development economists typically split these determinants into two groups. Economic determinants are tangible and measurable: things like capital, resources, and the efficiency with which investment converts into output. Non-economic determinants are less visible but just as powerful: the skills of the workforce, the state of technology, the quality of institutions, and the stability of the political environment. Neither category works in isolation. A country can have abundant capital and still stagnate if its institutions are weak, just as it can have a brilliant, educated population and still struggle without enough investment to put that talent to use.

Economic determinants of development 🔗

These are the factors that show up directly in national income accounts and investment data. They are the machinery of growth, the part of the story that can be measured in rupees, tonnes, and percentages.

Capital formation: building tomorrow’s productive capacity 🔗

Capital formation refers to the net addition to a country’s stock of productive assets such as machinery, factories, roads, and irrigation systems. It is not the same as accumulating money; it means converting part of today’s output into equipment and infrastructure that can produce even more output tomorrow.

The logic is straightforward. When households save instead of spending everything they earn, and when businesses and governments channel those savings into new factories, highways, or power plants, productive capacity expands. Higher capacity means more goods and services can be produced with the same labour force, which raises national income. That higher income then generates fresh savings, and the cycle repeats. This is why economic planners watch the domestic savings rate so closely; it is the fuel that feeds the entire growth engine. A country’s telecom rollout or highway expansion in one decade often shows up as new jobs, new businesses, and higher exports in the next.

Natural resources: potential, not destiny 🔗

The availability of natural resources such as fertile land, minerals, water, and energy sources is often the first thing people associate with a country’s growth potential. Abundant resources can lower the cost of production and support entire industries, from agriculture to mining to manufacturing.

But resources alone guarantee nothing. Several resource-rich nations have failed to translate their mineral or oil wealth into broad-based development because the gains were captured by a narrow elite, mismanaged, or drained by weak governance rather than reinvested in productive capacity. Conversely, resource-poor economies such as Japan and Singapore built prosperity by importing raw materials and adding value through skill and technology. Natural resources are best understood as an opportunity that still needs the right economic and institutional conditions to be realised.

Capital-output ratio: how efficiently investment turns into growth 🔗

The capital-output ratio measures how much capital investment is needed to generate one additional unit of output. If an economy invests 32 percent of its GDP and grows by 8 percent, the ratio works out to 4, meaning four units of capital are required to produce one unit of extra output. Planners use this ratio to work backwards from a growth target to figure out how much investment is actually needed, a method that has long informed India’s approach to investment planning.

A lower capital-output ratio is desirable because it signals that capital is being used efficiently, usually because of better technology, skilled management, or improved infrastructure. A rising or high ratio, by contrast, points to inefficiencies such as poor infrastructure, red tape, or underused capacity, all of which force the economy to invest more just to achieve the same growth. The related concept, the incremental capital-output ratio, tracks how much additional investment is needed for each additional unit of growth, making it a more dynamic tool for policymakers tracking year-on-year efficiency.

Non-economic determinants of development 🔗

Once the economic building blocks are in place, growth still depends on forces that don’t appear directly on a balance sheet. These non-economic determinants often decide whether capital and resources are put to good use or wasted.

Human resources: the most valuable asset an economy has 🔗

A country’s workforce is only as productive as its health and education allow it to be. Human capital formation is the process of building knowledge, skills, and physical wellbeing in a population through spending on schooling, healthcare, and training. The circular link between human development and growth is well established: better-educated, healthier workers are more productive, and that productivity generates the income that funds further investment in health and education.

India’s own numbers illustrate why this matters. The World Bank’s Human Capital Index found that a child born in India can expect to reach only around half of their full productive potential by adulthood, given prevailing health and education conditions, though this figure has improved compared with earlier assessments, according to a government release on the index. This is exactly why public spending on nutrition, school quality, and healthcare access is treated as an economic priority rather than just a welfare concern. Research on measuring human capital across countries confirms that education and health outcomes are strong predictors of a nation’s future workforce productivity, as documented in a global study on human capital covering nearly 200 countries.

Technological know-how 🔗

Technology determines how much output a given amount of capital and labour can produce. Economies that adopt better machinery, software, and production techniques get more value from every rupee invested, which directly lowers the capital-output ratio discussed earlier. This is why economists since Schumpeter have treated innovation, not just investment, as a central driver of long-term development. A country doesn’t need to invent every technology itself; importing and adapting existing techniques, as many late-developing economies have done, can be just as effective a growth strategy.

Institutional factors and governance 🔗

Institutions are the rules of the game: property rights, contract enforcement, regulatory quality, and the rule of law. Strong institutions give businesses the confidence to invest for the long term, while weak or corrupt ones discourage exactly the kind of capital formation discussed earlier. Studies of governance across developing Asian economies have found that government effectiveness, regulatory quality, and control of corruption have a measurably stronger link to growth than some other governance indicators, based on research from the Asian Development Bank. Where institutions are extractive rather than productive, even resource-rich or capital-rich economies can underperform their potential.

Political stability 🔗

Investors, whether domestic or foreign, need a reasonable degree of certainty that today’s policies will still hold tomorrow. Political instability disrupts this certainty, delays infrastructure projects, and can trigger capital flight, all of which slow development. Academic analysis across dozens of countries has consistently linked greater political stability with stronger growth outcomes, though research also cautions that excessive, unchallenged stability can eventually breed complacency and resistance to reform, a finding explored in a comparative study of governance quality in Asia. The healthiest environment for development, in other words, is stable enough to plan around but open enough to keep improving.

Why both sets of factors have to work together 🔗

The clearest lesson from comparative development history is that economic and non-economic determinants reinforce each other rather than operating independently. Economies that combined steady capital formation with heavy investment in education, disciplined institutions, and political continuity industrialised rapidly and moved up the technology ladder within a few decades. Economies that focused on capital formation alone, often financed through heavy borrowing, without parallel investment in institutions and human capital, tended to run into inefficiency, debt problems, or stalled growth once the initial investment advantage wore off.

This is also why development strategy cannot be reduced to a single lever. Boosting the savings rate matters, but so does improving learning outcomes in schools. Attracting investment matters, but so does strengthening regulatory institutions that make that investment worthwhile in the first place.

What do you think? Between capital formation and human capital, which do you think matters more for a country at India’s current stage of development, and why? Can strong institutions compensate for a shortage of natural resources, or does resource scarcity set a hard limit on how far development can go?
