This is a plain-language summary of “Foreign Direct Investment and Economic Growth in India: A Production Function Analysis” (Pradhan, The Indian Journal of Economics, 2002).

In short:

Treating the economy as a production process with three inputs — domestic capital, foreign capital, and labour — the study measures how much each contributed to India’s output over 1970–1997.
Over the full period, FDI’s effect was positive but not statistically significant; domestic capital did the heavy lifting.
The key twist: when the period is split, FDI’s effect becomes statistically significant only after liberalization — the opening-up itself is what made foreign investment start to count.

The question

In the early 1990s, India had to decide how far to open its economy to foreign capital. Behind that political question sat an empirical one: when foreign companies invest in India, does it actually raise output? This study by Jaya Prakash Pradhan answers it with a production-function analysis — modelling the economy as if it turns inputs into output, and estimating how much each input contributes. The three inputs are domestic capital (machines, buildings, plant), foreign capital (the accumulated stock of FDI), and labour (the workforce).

A door that opened in stages

The backdrop is India’s shift from a closed to an open investment regime — visible in how much foreign capital had actually accumulated.

In the restrictive years (1970s to mid-1980s), tight controls kept the foreign presence small — an average FDI stock of about ₹582 crore (in the rupee values of that era). The transition of the mid-1980s to early 1990s roughly doubled it, to about ₹1,045 crore. And the reform era of 1992–1997 saw it jump to about ₹4,727 crore as India actively courted foreign investors. (These are nominal figures in their original pre-1997 terms — small by today’s standards, but the trajectory is the point.)

What actually drove output

Here is where the production-function estimates do their work — and they’re refreshingly honest about FDI’s modest measured role.

Over 1970–1997 as a whole, domestic capital was overwhelmingly the biggest driver: a 1% rise in domestic capital was associated with roughly a 0.87% rise in output. Labour came next at about 0.24%. Foreign investment registered as positive but small — about 0.02% — and not statistically significant over the full period. On its own, that might read as “FDI didn’t matter much.” But the study’s central move is to split the sample by policy regime, and that changes the picture: in the post-liberalization phase (the late 1980s and 1990s), FDI’s estimated effect rises to about 0.04% and becomes statistically significant, whereas in the restrictive earlier years it had been positive but insignificant. In other words, foreign investment began to register in the growth data precisely when the policy regime opened to let it work.

What it means

The finding is more interesting than a simple thumbs-up for FDI. It suggests that foreign investment’s contribution to growth was conditional on the policy environment — it became a measurable, significant contributor only once liberalization removed the constraints around it. That’s an argument for the reforms: the opening-up didn’t just let in more foreign capital, it appears to have let that capital actually contribute to output. At the same time, the study is candid that domestic capital remained the dominant engine of Indian growth throughout — so the sensible reading is about balance: welcoming foreign investment while continuing to build domestic strength, rather than treating FDI as a substitute for it. As an early, compact piece of econometric evidence from just after the reforms, it’s a measured contribution to the long debate over whether opening up paid off.

Read the academic abstract

The economic role of FDI has become increasingly significant in the Indian economy with the transition of FDI policy from the restrictive phase of the 1970s and early 1980s to the relatively liberal phase of the late 1980s and 1990s. In this context, it is essential to investigate whether FDI contributes positively or negatively to the production process. Estimation of a production function for the Indian economy suggests that the FDI stock contributed positively to national production. Although the FDI impact was not significant for the overall period, bifurcating the sample indicates a significant impact in the relatively liberal policy phase.
