Impact of Digital Economy on Energy Supply Chain Efficiency: Evidence from Chinese Energy Enterprises

Abstract

The global industrial chain and energy supply chain are being reconfigured at an accelerated pace, and the uncertainty of China’s energy supply security is growing significantly. Empowering energy supply chains through the digital economy (diec) has a positive effect on accelerating the transformation of China’s energy supply structure. This paper discusses the effect and mechanisms of the digital economy on energy supply chain efficiency (esce). Specifically, based on the panel data of 112 energy enterprises in China from 2011 to 2019, energy supply chain efficiency and digital economy at the enterprise level were evaluated through three-stage DEA and content analysis, respectively. A two-way fixed effects model and mediation effect mode were adopted to investigate the nexus of diec and esce. The results show that the digital economy improves energy supply chain efficiency, and the conclusion holds water even after a series of robustness tests and endogenous treatment. Meanwhile, its promotion effect is more significant among large enterprises, non-state enterprises and enterprises in high market-oriented regions. The main impact mechanisms are regional industrial agglomeration and technological innovation of enterprises. Based on the above conclusions, it is suggested to take advantage of the industrial aggregation effect and technological innovation effect of the digital economy to further improve the efficiency of the energy supply chain for the purpose of maintaining energy supply security.

Assessing the Impact of Digital Technologies on Energy Efficiency: The Role of OFDI and Virtual Agglomeration

“…With the deepening of the integration of digital technologies, automatic early warning monitoring and control at the millisecond level will be expected in the future. For example, intelligent solutions help improve supply chain link efficiency, such as enterprise production and operation, and improve the efficiency of energy resource allocation (Fu et al, 2023). Supply chains for specific energy sectors, such as the energy and gas industry, are complex systems that involve sales decisions by oil suppliers/distributors, market prices, refining operations, gantry operations, and product transportation.…”

The relationship between digital economy and industrial green innovation efficiency – based on the perspective of external knowledge sources

“…The innovation-leading effect will be stimulated, thus help reducing energy consumption and improving the efficiency of industrial green innovation. At the same time, by optimizing the traditional industrial structure, changing the production mode and improving the efficiency of the supply chain (Luo et al, 2023;Fu et al, 2023;Mikhaylova et al, 2021), the digital economy forces the industrial upgrading of enterprises. These can help enterprises gain new competitive advantages to better exchange and integrate knowledge with external organizations, thus enhancing innovation capabilities.…”

Impact of digital technology on carbon emissions: Evidence from Chinese cities

“…Zhao et al (2020) found that the digital economy can enhance entrepreneurial activity and promote high-quality economic development using empirical research on the panel data of 222 cities above the prefecture level in China. In addition, several studies have analyzed the impact of DT on trade in services (Zhou L. et al, 2023), total factor energy efficiency (Fu et al, 2023;Huang et al, 2023), knowledge innovation (Orlando et al, 2020;Wang and Li, 2023), economic growth (Qu et al, 2017), air pollution , and green total factor productivity (Guo et al, 2022;Zhao et al, 2022).…”
