Digital Economy Effects in Smart Logistics Growth: Spatial Patterns and Financial Thresholds
This study of 30 Chinese provinces from 2015 to 2024 reveals that while the digital economy lacks a significant direct impact on local smart logistics growth, it exerts a robust negative spatial spillover effect, with financial deepening showing only tentative conditional relevance and causal identification remaining limited.

In the modern world, the digital economy acts as a vast, invisible nervous system for business. It is the collection of internet infrastructure, software services, and data flows that allow companies to communicate, trade, and organize themselves with unprecedented speed. Logistics, the physical movement of goods from factories to homes, has long been the industry most eager to tap into this power. The hope has been that by feeding more digital technology into the supply chain, the entire system would automatically become faster, cheaper, and more efficient. This idea is so widely accepted that governments and corporations have poured billions into building smart warehouses, automated sorting centers, and AI-driven delivery routes. Yet, a critical question remains unanswered: does simply adding more digital tools actually guarantee that the logistics industry will grow? Or are there hidden conditions and regional dynamics that determine whether these investments succeed or fail?
A team of researchers from West Anhui University set out to test this assumption by looking at the real-world performance of China's logistics sector over a decade. They analyzed data from thirty provinces between 2015 and 2024, a period that included the massive disruption of the global pandemic. Instead of just measuring how big the digital economy was or how efficient logistics became at a single moment, they focused on the rate of growth. They wanted to see if digital expansion actually drove the industry to expand faster, and if so, how that growth spread across the map. Their investigation revealed a story far more complex than the simple promise of automatic efficiency. They found that the benefits of the digital economy do not stay neatly within the borders where the technology is installed. Instead, the growth of smart logistics is shaped heavily by how regions interact with their neighbors, often in ways that create competition rather than cooperation.
The researchers began by asking a straightforward question: if a province invests heavily in digital technology, does its own logistics sector grow faster as a result? When they looked at provinces with similar economic levels, the answer was surprisingly quiet. There was no strong statistical evidence that digital investment automatically translated into faster logistics growth in the same location. The effect was so weak that it was difficult to distinguish from random noise. This lack of a direct, automatic link suggests that simply buying more servers or building more data centers is not a magic switch for growth. The technology requires time to be absorbed, and its impact is often masked by other factors like local demand, infrastructure quality, and market conditions.
However, when the researchers changed their lens to look at geography, a clear and unexpected pattern emerged. They examined how a province's digital economy affected the logistics growth of its immediate neighbors. Here, the data told a different story. While a province's own digital growth showed only a faint, marginal positive link to its own logistics, the digital growth of its neighbors had a distinct negative impact. When a neighboring province advanced its digital capabilities, the local logistics growth in the adjacent area tended to slow down. This suggests a "siphoning" effect, where digital resources, talent, and market share are drawn toward the leading region, leaving its neighbors with fewer opportunities. It is as if the digital economy creates a gravity well, pulling the most valuable elements of the logistics network toward the center and leaving the periphery struggling to keep up. This negative spillover was the most consistent finding in the study, holding true across alternative weight matrices and extended time windows; however, when the researchers excluded the pandemic years, the local positive effect vanished entirely, and the negative indirect effect remained significant at the 10% level, indicating that the evidence for this competitive structure is robust.
The study also explored whether the local financial environment acted as a gatekeeper for these effects. The idea was that digital technology might only work if a region had enough access to loans and capital to fund the necessary upgrades. The researchers found some evidence for this, but only under specific conditions. In a model that ignored the influence of neighboring regions, they saw that when financial support crossed a certain threshold, the positive impact of the digital economy became stronger. However, once they brought the spatial competition back into the equation, this financial threshold effect disappeared. This indicates that the ability of money to unlock digital growth is fragile and easily overwhelmed by the competitive pressure from nearby regions. The financial condition is not a reliable, standalone key to success; its role is secondary to the complex dance of regional rivalry.
The researchers also tested a common theory that digital growth happens because companies cluster together, forming denser networks that share information and resources. They looked to see if the density of logistics firms was the missing link that explained how digital tools improved efficiency. The data did not support this. The network density of firms did not act as a bridge for the digital economy to boost growth. This ruled out a popular explanation and pointed the finger elsewhere, suggesting that the mechanisms at work are likely more subtle, involving supply chain coordination or technology diffusion that is harder to measure with current data.
Ultimately, the study paints a picture of a digital economy that is powerful but uneven. It does not act as a uniform engine that lifts all boats equally. Instead, it operates through a spatial dimension where the success of one region often comes at the expense of its neighbor. The most reliable finding is that digital advancement in one place can suppress growth in the next, creating a landscape of winners and losers based on geography. This challenges the notion that digital investment is a guaranteed path to prosperity for every region. For policymakers, the lesson is clear: throwing money at digital infrastructure without considering the broader regional context may lead to a zero-sum game where one province's gain is another's loss. The path forward requires looking beyond the local borders and designing strategies that manage these competitive tensions, ensuring that the digital revolution lifts the entire network rather than just the strongest nodes. The evidence suggests that the future of smart logistics depends less on the sheer volume of digital inputs and more on how regions coordinate to share the benefits rather than fight over them.
