Outline
In order to solve the incompatibility between the green development capability indicators of non-ferrous metal enterprises and the lack of full consideration of subjectivity and objectivity in the process of index weighting, an evaluation model of green development capability of non-ferrous metal enterprises based on game theory combined weighting-improved matter-element extension model was proposed. Firstly, through literature analysis and consulting experts, the evaluation index system of green development capability of non-ferrous metal enterprises was constructed. Secondly, the subjective weight and objective weight of the evaluation index were calculated by the genetic algorithm-analytic hierarchy process and the CRITIC method respectively, and the comprehensive weight was calculated according to the game theory. Finally, the asymmetric closeness degree criterion was used to replace the maximum correlation degree criterion, and the evaluation model of green development capability of non-ferrous metal enterprises based on the improved matter-element extension model was established, and the model was studied by an example. The research results show that the evaluation grade is consistent with the bias degree of the previous year, which verifies that the green development capability evaluation of non-ferrous metal enterprises based on the improved matter-element extension model has certain reliability and accuracy.
