Beyond Adoption: A Complementarity Threshold in the Digitalization–Innovation Nexus in the Brazilian Industry
Using firm-level data from 1,435 Brazilian industrial enterprises, this study demonstrates that the innovation benefits of digitalization emerge only when firms adopt a comprehensive, complementary portfolio of six advanced technologies rather than isolated tools, suggesting that systemic digital transformation is a more stable strategic commitment than piecemeal adoption.

In the modern industrial world, companies are constantly asked to embrace the digital revolution. The prevailing wisdom suggests that simply picking up a new digital tool—whether it is a system for analyzing massive amounts of data, a network of connected sensors, or software for artificial intelligence—is enough to spark innovation. The assumption is linear: more technology leads to better products and smarter processes. However, this view often overlooks a crucial complexity. Digital tools rarely work in isolation; they are part of a vast, interconnected ecosystem where the value of one tool often depends on its ability to talk to others. Just as a single instrument in an orchestra cannot create a symphony, a single digital technology may not be enough to transform how a factory operates. The question facing economists and business leaders is whether the benefits of digitalization come from adopting a few scattered tools or from weaving them together into a complete, coordinated system.
This question is particularly pressing in emerging economies like Brazil, where the industrial landscape is a mix of highly advanced sectors and traditional firms struggling with productivity. Researchers from several Brazilian universities and the national statistics office set out to investigate this dynamic by looking directly at the behavior of large industrial firms. They focused on 1,435 companies with at least 100 employees, drawing data from two major government surveys conducted in 2022. These surveys provided a rare, detailed snapshot of exactly which advanced digital technologies these firms were using and whether they had introduced new products or improved their manufacturing processes that same year. The researchers zeroed in on six specific technologies: Big Data analytics, Cloud Computing, Artificial Intelligence, the Internet of Things, Additive Manufacturing (often known as 3D printing), and Robotics.
The study tested two distinct scenarios to see which one actually led to innovation. The first scenario looked at firms that had adopted at least one of these six technologies, representing a partial or entry-level approach to digitalization. The second scenario examined a much smaller, more exclusive group of firms that had adopted all six technologies simultaneously, representing a comprehensive digital transformation. The results revealed a clear threshold effect. Firms that had merely adopted one or a few digital tools showed no statistically significant increase in their likelihood of innovating. In other words, picking up a single tool did not automatically make a company more innovative. However, the picture changed dramatically for the firms that had integrated all six technologies. These companies were significantly more likely to introduce new products, new processes, or both. The data suggested that the innovative power of digitalization does not come from the tools themselves, but from the way they are combined and used together.
To ensure these findings were not just a coincidence caused by the fact that already-innovative companies happen to buy more technology, the researchers used a sophisticated statistical method to account for hidden factors. They found that the link between partial adoption and innovation was shaky; it appeared that companies which were already innovating were simply the ones most likely to buy a single digital tool. This suggested that isolated adoption was often a reaction to existing success rather than a cause of it. In contrast, the decision to adopt the full suite of six technologies behaved differently. It showed no signs of being driven by past innovation habits, suggesting it was a deliberate, stable strategic commitment. When a company invests in a complete digital portfolio, it is making a structural change to how it operates, and this deep integration is what drives the creation of new products and processes.
The study also highlighted that digital transformation does not happen in a vacuum. The companies that successfully leveraged these six technologies were also the ones investing heavily in research and development, collaborating with outside partners, and utilizing government support. The digital tools acted as a powerful amplifier, but they required a foundation of human capability and organizational support to work. For policymakers and business leaders, the implication is clear. Supporting the purchase of isolated digital gadgets may not yield the desired results. Instead, the path to genuine innovation lies in encouraging firms to build comprehensive digital systems where different technologies work in harmony, supported by strong internal research and external cooperation. The evidence from Brazil suggests that the future of industrial innovation belongs not to those who buy the most tools, but to those who learn how to make them work together.
