Abstract: Green supply chain management (GSCM) practicing mode has become one of the hot topics to scholars and managers. Because buyers increasingly expected purchasing behavior and the supply chain operation is conducive to environmental protection. Pressuring and monitoring suppliers to become more environmentally responsible dominates the coercive approach to GSCM. In contrast, a cooperative approach is associated with training and helping suppliers to become ‘greener’. In this study, we draw on institutional theory, and probe into the mode selection of green supply chain management practicing, the results show that coercive and cooperative mode choice depends on the institutional pressure (mimetic, normative and coercive) and downstream customers demand for green supply chain management. Through the analysis of the survey data of 262 companies, results reveal that the coercive or cooperative mode selection of green supply chain management practice is driven by different factors: Institutional pressure significantly determines the cooperative green supply chain management; And coercive mode in a larger extent, is driven by the downstream customer demand, the downstream customer needs adjust the cooperative mode, but no significant effects have been found for coercive mode.
