The construction industry must change the traditional extensive mode of production and take the sustainable development road.The promotion of green supply chain in the construction industry is conducive to improving the high consumption of resources,serious environmental pollution,and beneficial to the realization of green building.In the meanwhile,choosing a suitable supplier is a key to ensure that the green supply chain operates effectively.Therefore,according to the characteristics of green material suppliers,this paper establishes the evaluation indicator system of green material suppliers from the following three aspects: product level,enterprise status and green level,and then constructs the green material supplier selection model with Entropy Weight method and TOPSIS method.Finally,this paper carries out empirical research to test the effectiveness of the model.
