Can the digital economy reduce carbon emission intensity? Chinese research offers a new perspective for Africa's green transition

Global climate governance is entering a critical decade. China's commitment to peak carbon emissions before 2030 and achieve carbon neutrality before 2060 makes its cities a natural testing ground for examining the synergy between digitalization and emission reduction. A study recently published in *Humanities and Social Sciences Communications* used panel data from 249 Chinese cities from 2010 to 2019 to systematically examine the impact of digital economy development on urban carbon emission intensity. The core conclusion is that digital economy development is indeed associated with a decline in carbon emission intensity, but this relationship is not a simple linear decline; rather, it exhibits obvious regional heterogeneity and technological generational differences.

Key findings: Nonlinearity and regional divergence

The study used fixed-effects models and nonparametric additive models to identify a complex relationship between the digital economy and carbon emission intensity. At the national level, the digital economy lowered urban carbon emission intensity overall. By region, eastern and central cities showed a consistent downward trend, while western cities exhibited an inverted U-shape—carbon emission intensity may rise in the early stage of digitalization and begin to decline only after crossing a certain threshold.

The study further distinguished between the traditional digital economy and the new-generation digital economy. The traditional digital economy mainly refers to internet infrastructure and informatization applications; the new-generation digital economy encompasses frontier technologies such as big data, artificial intelligence, and cloud computing. The results show that the new-generation digital economy has demonstrated broader and more stable emission-reduction effects in the eastern, central, and western regions, while the environmental performance of the traditional digital economy varies significantly across cities.

Development logic: Efficiency gains and technological generational leap

Why can digital technology reduce carbon emissions? The core mechanism is efficiency improvement. Digital platforms optimize logistics scheduling, smart grids precisely match supply and demand, and digitalization also promotes the upgrading of industries toward knowledge-intensive forms. These structural changes naturally reduce energy consumption per unit of output. However, the appearance of the inverted U-shaped relationship indicates that digitalization does not reduce carbon immediately upon launch. The construction of data centers and the manufacturing and disposal of electronic devices are themselves accompanied by carbon emissions. In the early stage of industrialization, large-scale deployment of digital infrastructure may push up energy consumption. Only when digital technology deeply penetrates production processes and begins to replace high-carbon factors do the emission-reduction effects become apparent. Therefore, the stage of development and regional endowments are crucial.

Implications for Africa: Crossing the digital high-carbon fence

Africa is one of the fastest-growing regions for the digital economy globally. Mobile payments, e-commerce, and remote services are reshaping its economic landscape. At the same time, Africa still faces challenges such as power shortages and weak basic industries. The greatest insight from the Chinese study is that digitalization and low-carbon development are not naturally synergistic linear processes; rather, they depend on the way infrastructure is built and the choice of technological pathways.When African countries launch large-scale digital infrastructure, they can proactively design renewable energy as the primary power source. For example, solar resources in sub-Saharan Africa can power data centers, reducing operating costs while avoiding carbon lock-in. In other words, Africa has the opportunity to leverage late-mover advantages to directly build a green digital foundation, skipping the inverted U-shaped rising segment that once appeared in western China.

Regional Development: Green Digital Standards under the AfCFTA Framework

The African Continental Free Trade Area is promoting cross-border digital trade. If member states compete to lower environmental standards in order to attract investment, this could lead to regional carbon leakage. The differences among China's eastern, central, and western regions remind Africa that a unified green digital standards framework is more efficient than exploring separately. Regional organizations can draw on China's experience by coordinating early on digital economy statistics, carbon emission accounting, and data-sharing mechanisms, laying green rules for cross-border digital supply chains.

The Next Five to Fifteen Years: Green Digital Growth Poles

In the next 10 to 15 years, Africa's youth population will reach a historical peak. If digital education and new-generation technical training become widespread, Africa is expected to form industrial clusters centered on green data services, smart energy, and low-carbon logistics. The conclusion in China's research that "the new generation of digital economy reduces carbon more steadily" suggests that Africa does not need to copy the traditional path of informatization, but can directly invest in cutting-edge technologies such as artificial intelligence, the Internet of Things, and blockchain traceability for renewable energy management and cross-border trade.

Of course, this requires policy coherence and sustained infrastructure investment. African countries also need to be vigilant against digital-colonial-style data outflow. Only by building their own digital capabilities and green technology systems can Africa truly turn its demographic dividend into sustainable growth momentum.

Key Node Assessment

For Africa, the significance of this Chinese study lies not in providing ready-made experience, but in revealing a fundamental choice: the carbon trajectory of the digitalization process is not predetermined. Africa can become the first continent in the world to build digital infrastructure directly on clean energy. If this choice can be put into practice within the next decade, the African continent will not only avoid becoming a follower of the "high-carbon digital era", but may instead become a key node in the global narrative of green digital growth.
