This is a plain-language summary of “Regional Heterogeneity and Firms’ R&D in India” (Innovation and Development, 2011).
In short:
- Corporate R&D in India is heavily concentrated — just five states account for over 67% of all manufacturing R&D investment.
- What drives a firm’s R&D isn’t what you’d guess: science-and-technology institutions, a technology-intensive industrial base, and the presence of foreign firms matter most.
- The “obvious” factors — market size, the size of the local talent pool, and telecom infrastructure — barely mattered, a notable contrast with what drives patenting and enterprise creation.
Innovation has an address
Whether a manufacturing firm invests in research turns out to depend not only on the firm itself, but on where it sits. Using a firm-level dataset spanning 1991–2008, this study maps corporate R&D across Indian states — and finds it strikingly uneven. Over two-thirds of all manufacturing R&D comes from just five states. The rest of the country, between them, accounts for less than a third.
What actually drives a firm’s R&D
The interesting part is why. The study tests a wide range of regional conditions, and the ones that matter are not the ones conventional wisdom would nominate.

Three regional factors stand out. Science-and-technology institutions raise local firms’ R&D through knowledge spillovers — and the benefit reaches both high-tech and low-tech firms. A technology-intensive industrial base lifts R&D across the board: even low-tech firms innovate more when they sit among high-tech neighbours. And the presence of foreign firms pushes domestic firms to invest more, through a mix of competitive pressure and knowledge transfer.
What’s striking is what didn’t matter. Market size had little effect — firms in smaller states innovated just as actively. The size of the local talent pool mattered surprisingly little, because skilled people are mobile and move to where the work is. And telecommunications infrastructure played only a minor role. For research intensity, in other words, being near knowledge and sophisticated industry beats being near a big market or a big labour pool.
The firm still matters too
Location isn’t everything — a firm’s own characteristics shape its R&D as well:
| More R&D | Less R&D |
|---|---|
| Older, established firms | Younger firms |
| Export-oriented firms | Domestically focused firms |
| Foreign-owned firms | Smaller firms |
| Business-group affiliates | Standalone firms |
So the firms most likely to invest in research are established, outward-looking, and connected — and they do still more of it when they sit in the right regional ecosystem.
What it means
For state governments, the levers that follow are concrete: invest in science-and-technology institutions, attract technology-intensive manufacturing, build academia–industry links, and spread these innovation assets more evenly rather than letting them pool in a handful of states. For firms, the lesson is that location is a strategic choice — proximity to research institutions, to foreign firms, and to industrial clusters can do for a smaller firm what its own size cannot.
Read the academic abstract
The present study seeks to examine the influence of regional factors on firm-level R&D activities in an emerging economy. Based on a unique firm-level dataset, it shows that total manufacturing R&D investment in India is unevenly distributed regionally, with a few Indian regions and states accounting for a disproportionate share of it. This inter-state disparity in the magnitude and intensity of manufacturing firms’ R&D continued during the period 1991–2008. The empirical results, obtained from a multidimensional framework of analysis, confirm that a group of regional factors — the local abundance of science and technology (S&T) institutions, the presence of a greater number of foreign firms, and a technology-intensive structure of manufacturing — play an important role in shaping the R&D intensity of the sample of firms.Cite this article

This is one of three studies in which I map the geography of innovation in India — and, read together, they make a subtle point: different innovation outcomes have different regional drivers.
- Innovation Nation: The Hidden Geography of India’s Patent Revolution — where market size and skills are central to patenting…
- Where Do India’s Small Businesses Thrive? The Geography of Entrepreneurship — where those same factors drive enterprise creation…
- …yet here, for firm R&D, it’s institutions, industrial structure, and foreign presence that matter, while market size barely registers.
