Twin Transition: Do 5G Applications Really Improve Corporate Environmental, Social, and Governance (ESG) Performance?
This study utilizes a difference-in-differences model on Chinese listed firms to demonstrate that the 5G Pilot Program significantly enhances corporate ESG performance by accelerating digital transformation and promoting green technological innovation, with stronger effects observed in non-state-owned enterprises, high-tech industries, and eastern regions.

In the modern world, two massive shifts are reshaping how societies function: the rapid move toward digital technology and the urgent push for environmental sustainability. For years, these two paths have often been viewed as separate, or even conflicting. On one side, digital tools promise to make industries more efficient, transparent, and connected. On the other, the physical hardware required to build these digital networks—servers, cables, and communication towers—consumes vast amounts of energy and resources. This tension has led to a debate among experts: does building a smarter, more connected world actually help the planet, or does the sheer energy cost of that connection cancel out the benefits? This question sits at the heart of a concept known as the "twin transition," which describes the simultaneous journey toward a digital and a green future. To understand if this dual transformation works in practice, researchers needed to look beyond theory and examine real-world data from companies that have actually adopted these new technologies.
A team of researchers set out to investigate this question by studying the impact of fifth-generation mobile communication, or 5G, on how companies perform in environmental, social, and governance areas. These areas, collectively known as ESG, serve as a scorecard for how well a business manages its impact on the environment, treats its people, and runs its internal operations. The researchers focused their study on China, a country that launched a massive, carefully planned experiment in 2019. The government selected forty cities to serve as test sites for a new 5G pilot program, rolling out the technology in stages while other cities waited. This setup created a unique opportunity to compare companies in the pilot cities against similar companies in non-pilot cities, effectively isolating the effect of the new technology from other economic factors. The team gathered data on over fifty thousand listed companies spanning fifteen years, allowing them to track changes in ESG scores before and after the 5G networks went live.
The results of this extensive analysis were clear and positive. The study found that companies located in cities with the 5G pilot program saw a measurable improvement in their ESG performance compared to those without access to the new infrastructure. This suggests that the benefits of the technology—such as better data collection, more efficient resource management, and improved transparency—outweigh the energy costs of building the network. The researchers identified two specific ways this improvement happened. First, the presence of 5G accelerated the companies' own digital transformation, allowing them to integrate advanced software and monitoring systems into their daily operations. Second, the technology spurred an increase in green technological innovation, encouraging firms to develop cleaner production methods and new patents focused on environmental solutions.
However, the study also revealed that this benefit was not felt equally by everyone. The positive impact was strongest among private companies, which tend to be more agile and quicker to adapt to new market signals than state-owned enterprises. The effect was also most pronounced in the eastern region of China, where the existing digital infrastructure and skilled workforce were already more developed, and in high-tech industries that could immediately leverage the speed and connectivity of 5G. In contrast, companies in central and western regions, as well as those in traditional, non-high-tech sectors, saw little to no immediate change in their ESG scores. This indicates that while the technology holds great promise, its ability to drive sustainability depends heavily on a company's existing resources and its ability to absorb new tools.
The researchers took great care to ensure these findings were not the result of other policies or random chance. They tested their results against other major initiatives, such as smart city programs and broadband expansion, and found that the 5G effect remained distinct and significant. They also ran simulations where they randomly assigned the 5G status to different cities; in those scenarios, the positive results disappeared, confirming that the real-world rollout was indeed the cause of the improvement. The study concludes that while the energy footprint of building 5G is real, the systemic efficiency it unlocks creates a net positive for sustainability. For policymakers, this suggests that investing in next-generation digital infrastructure can be a powerful tool for achieving green goals, provided that support is also given to help less developed regions and traditional industries catch up. The evidence points to a future where digital connectivity and environmental responsibility are not competing interests, but rather partners in a shared transition.
