Abstract：The new generation of information and communication technology characterized by big data,5G and artificial intelligence has greatly promoted the digitalization process of the energy industry.Energy Internet is a new format produced by the deep combination of a new generation of digital technology and traditional energy industry.In 2016,the Guiding Opinions on Promoting the Development of"Internet+"Smart Energy started the process of China's energy Internet construction.The investment in digital technology accounted for about 11％of the total investment in the power grid from 2009 to 2020,and the investment of State Grid in the field of new digital infrastructure in 2021 was as high as 24.7 billion yuan.However,it is not clear what contribution digital technology will make to the development of the energy Internet industry.In order to quantitative analyze of the impact of digitalization on the comprehensive benefits of the energy Internet,based on the perspective of industrial chain,this paper adopted the method of System Dynamics theory to describe the key role of digital technology investment in upstream energy production,midstream energy transmission and downstream energy consumption of the energy Internet industry.It quantified and simulated the comprehensive impact of different types of digital technology investment on the economic,energy and environmental benefits of the Energy Internet Industry.The results show that digital technology investment plays a key role in improving the comprehensive benefits of energy Internet.In scenarios with a high proportion of digital technology investment,digital technology can greatly increase the total installed capacity of clean energy,reduce carbon dioxide emissions,and strongly support China's carbon emission reduction strategy.Moreover,it is expected that by 2025,the increase in investment of digital technology will provide nearly 720,000 jobs per year for Chinese society,strongly supporting the development goals of China's 14th Five-Year Plan.
