Discussing measurement criteria and competitive strategies of green suppliers from a green law perspective

Abstract

Green suppliers form an active and independent green production management system that complies with green manufacturing regulations, eliminates bottlenecks and difficulties encountered by enterprises related to the requirements of green products, and enhances enterprises’ green competitiveness. Previous studies on competitive indices and strategies of green suppliers have generally had two limitations. First, most studies have assumed that competitive indices are independent of one another and are not causally related. Second, several studies have assumed that the weights of the evaluation indices are identical. To overcome these two limitations, this study integrated simultaneous importance-performance analysis and decision-making trial-and-evaluation laboratory methods and proposed a simultaneous importance-performance analysis–decision-making trial-and-evaluation laboratory model. In this study, simultaneous importance-performance analysis was used to explore the green performance and competitive situations of a case company and its competitors. Subsequently, decision-making trial-and-evaluation laboratory was used to calculate the degrees of influence that the competitive indices of green supplier regarding green performance exhibited on each other and to investigate the causal relationships among the competitive indices. Finally, competitive green supplier strategies for the case company were proposed. The results indicated that the method developed in this study not only provides theoretical contributions but also can be applied to businesses.
