Evaluation of the Development Maturity of Emerging Industry of Energy Internet Based on Entropy Weight Matter-Element Model

The emerging industry of energy Internet represents the direction of a new round of scientific and technological revolution and industrial change, and is the key to cultivate new drivers of development and gain new competitive advantages in the future. Based on the connotation, development direction and features of the emerging industry, this study designs 11 second-level indicators from 5 dimensions, including operation ability, innovation ability, social benefits, ecological benefits and information development, and constructs an entropy weight matter-element model for the evaluation of emerging industries' development. In addition, according to the theory of industrial maturity, the development level of emerging industry is divided into five stages, namely, forming, initial, growth, maturity and maturity optimization. And a theoretical model of development maturity evaluation of emerging industry is constructed. Further, this study takes the indicators of energy + e-commerce industry in 2019 as an example to evaluate its development maturity. The results show that the development maturity of the industry in 2019 is in the growth stage, and the fixed asset investment and information level of core business need to be further improved. The research model in this study provides a certain research basis for the development maturity of emerging industry of energy Internet.
