The construction of energy internet enterprises is an important way for new round of energy revolution and green friendly development in China. For achieving high efficient use of energy

it is imperative to study the fusion of industry chain of energy internet enterprises. First

a multi-dimensional and integrative method is used to analyze the constituent elements of upstream

midstream

and downstream industries in the energy internet system.The multi-energy comprehensive utilization system of one-stop energy internet enterprises based on multiple subjects and the linkage of supply and demand is studied and proposed by using internet data center and block chain. Then

the optimization configuration mode of of profit mechanism

core competitiveness and energy internet of the energy internet enterprises are discussed on the basis of agile manufacturing concept

big data and artificial intelligence technology

and the horizontal complementary and vertical optimization of multi-industry energy supply is achieved. Finally

it is proposed to accelerate the transformation in the field of energy supply and consumption pattern under the environment of energy internet and the countermeasure suggestion on exploring the potential value of energy utilization. The conclusions of the study have important implications for the energy internet enterprises to achieve construction of relevant mechanism and countermeasures of fusion of industry chain.
