The Impact Mechanism Research of Integrated Development of Electricity, Computing Power and Energy Storage—Based on Mediating Effect Model Inspection

Against the backdrop of the global energy transition and the in-depth advancement of the digital economy, the integrated development of electricity, computing power and energy storage has emerged as a core pathway to achieving energy security, digital transformation, and low-carbon development. This paper presents a theoretical analysis framework to examine the impact of integrating electricity, computing power, and energy storage, focusing on its direct effects on upgrading the regional industrial structure, improving energy efficiency, and constructing a new type of electricity system, as well as its indirect effects mediated by technological innovation, industrial agglomeration, and the intensity of policy support. Using panel data from 30 Chinese provinces from 2016 to 2025, the paper empirically tests the multi-path impact mechanism of electricity, computing power, and energy storage integration. Stepwise regression and bootstrap tests are adopted for the mediating effects model. The results show that: (1) the electricity, computing power and energy storage integration have a significant positive direct impact on regional high-quality development, which is more pronounced in regions with advanced digital infrastructure and superior energy resources. (2) Technological innovation and industrial agglomeration partially mediate the impact path of the electricity, computing power and energy storage integration, whereas the mediating effect of policy support intensity is insignificant. (3) The mediating effects vary across different regions. Specifically, technological innovation plays a stronger mediating role in eastern China, while industrial agglomeration has a more significant impact in central and western China. This paper clarifies the transmission path of electricity, computing power and energy storage integration, providing empirical evidence and policy implications for optimizing the integrated industrial development model and promoting high-quality economic growth.
