Spatial Pattern and Structural Transformation of China's Industrial Carbon Emissions: From Coastal Concentration to Inland Diffusion

Introduction The continuous rise in global industrial carbon dioxide emissions, primarily driven by fossil fuel combustion, poses a severe challenge to achieving climate goals. In China, the industrial sector is the largest source of carbon emissions, and its spatial distribution and structural transformation are core issues for the national "peaking carbon and carbon neutrality" strategy. This study aims to utilize multi-scale spatial analysis methods to quantify the evolution of China's industrial carbon emissions, reveal their driving factors, and provide engineering and policy perspectives for regional energy policy formulation.

Industry Background ### Current Energy Structure and Challenges Globally, although the deployment of clean energy is accelerating, fossil fuels maintain a strong position in the industrial sector. As one of the world's largest industrialized economies, the long-term evolution of China's industrial carbon emissions exhibits significant regional and structural characteristics. Data indicates that despite a slowdown in the overall growth rate under policy intervention, the carbon emission intensity and structure in specific regions remain volatile.

Policy Environment China's "dual carbon" goals (carbon peak by 2030, carbon neutrality by 2060) set a clear long-term direction for deep decarbonization in the industrial sector. The stringency of policies is manifested in the comprehensive promotion of energy efficiency improvements, clean energy substitution, and industrial structure adjustment. However, the effectiveness of policies is also coupled with industrial development, regional economic structure, and environmental governance capabilities.

Global Development Trends International research points out that the growth trend in global industrial carbon emissions is closely related to global economic development and energy structure adjustments. Although technological progress has been made in some areas, fundamentally changing the production methods of high-emission industries remains key to achieving significant emission reductions.

Current Development Dynamics ### Quantification of Emission Volume and Intensity Changes Analysis of data from 2005 to 2020 shows a significant increase in China's total industrial $\text{CO}_2$ emissions. More noteworthy is the continuous downward trend in industrial carbon emission intensity per unit of GDP, indicating that the industrial structure is undergoing a technological and industrial upgrading process from high-carbon intensive to low-carbon intensive.

Fundamental Shift in Spatial Pattern Spatial analysis results reveal the core dynamic of China's industrial carbon emissions: "shift of the center westward." Emission centers are gradually diffusing from traditional coastal areas to inland regions. This phenomenon reflects the reshaping of industrial layout and the driving force of resource endowments on industrial activities. The study finds that certain resource-dependent regions, such as Xinjiang and Inner Mongolia, still have high-emission clusters, with their carbon emission intensity even exceeding the industry average, highlighting the significant reduction challenges across regions.

Structural Changes in Emission Sources Structural analysis shows that emissions related to energy consumption and those related to production processes exhibit different trajectories of change.### Structural Changes in Emission Sources Structural analysis shows that emissions related to energy consumption and those related to production processes follow different trajectories. The steady decline in energy-related emissions indicates the emission reduction effect brought about by optimizing the energy structure; however, the continued rise in process-related emissions suggests that future emission reduction efforts must shift from simply improving energy efficiency to "decarbonizing" the industrial production process itself (Process Decarburization).

Impact on Energy Systems ### Energy Supply and Security Perspective The spatial restructuring of industrial carbon emissions directly affects the matching of regional energy supply and demand. The expansion of industry in inland areas poses new challenges to the load distribution of regional power grids, requiring grid infrastructure to possess stronger regional control and resilience capabilities.

Electricity Costs and Environmental Benefits The structural changes in industrial carbon emissions are key determinants of future electricity costs and environmental benefits. If emission reductions rely solely on improving energy efficiency without effectively controlling process emissions, the expected climate benefits will not be achieved. Therefore, policymakers need to balance the needs of short-term economic growth with the avoidance of long-term climate risks.

Industrial Chains and Regional Coordination The phenomenon that "carbon transfer does not accompany economic convergence" points to the need for coordinated governance between regions. The transfer of carbon-intensive industries, if not accompanied by synchronized regional economic development and environmental governance, may lead to the transfer of environmental burdens to less developed areas, exacerbating structural contradictions between regions.

Facing Challenges ### Energy Storage Systems and Transmission Network Limitations Although the penetration rate of clean energy is increasing, the continuous growth in the industrial sector's demand for stable, low-cost electricity places extremely high demands on grid flexibility. The upgrade speed of existing transmission networks often fails to match the speed of industrial structural adjustments.

Financing and Technology Maturity Deep retrofitting of carbon-intensive industries (such as hydrogen substitution or CCUS application) requires huge upfront capital investment. Bottlenecks in project financing and the engineering maturity of key decarbonization technologies are current obstacles facing the energy transition.

Policy Uncertainty The varying emission intensities across regions demand differentiated policy interventions, but the lack of a unified, forward-looking, and executable regional emission reduction mechanism can lead to the fragmentation and inefficiency of policy implementation.

Future Outlook ### Changes in Energy Structure Over the next 20 years, the structural transformation of China's industrial carbon emissions will be even more pronounced. We expect the rate of decline in "energy-related emissions" to be strongly driven by technological innovation, while controlling "process-related emissions" will be the core factor determining the success or failure of overall emission reductions. The low-carbon path will become more dependent on deep technological innovation rather than simple energy substitution.

Investment Trends Green investment will accelerate from "scale expansion" to "deep decarbonization."### Investment Trends Green investment will accelerate the shift from "scale expansion" to "deep decarbonization." Capital will favor enterprises that can achieve fundamental changes in industrial processes, provide low-carbon technical solutions, and platform investment opportunities that can effectively manage inter-regional carbon flows and risks.

Global Energy Competition Landscape China's experience in managing industrial carbon emissions will provide important policy references for other rapidly industrializing economies globally. The focus of global energy competition will shift from "whose energy is cheaper" to "whose industrial production is more sustainable."<br>
