In order to implement the new development concept and improve the performance evaluation system of green supply chain of prefabricated Constructions in my country, a performance evaluation of green supply chain of prefabricated Constructions from the perspective of collaborative innovation is proposed. First, draw lessons from the balanced scorecard theory and apply it to construct a performance evaluation index system for the green supply chain of prefabricated Constructions based on the balanced scorecard. Meta-extension model. Then, the performance evaluation grade is determined by the asymmetric closeness of the matter element to be evaluated about the evaluation grade of each index and the characteristic value of the grade index. Finally, the established evaluation model is applied to a green supply chain of a prefabricated Construction, and the results prove the validity of the model.
