With the resource scarcity and environmental deterioration, green supply chain management (GSCM), as a practice of circular economy at the enterprise level, has become an important strategy for manufacturers to realize sustainable development. Based on the literature and suggestions from international and domestic environmental experts, we developed a questionnaire and completed a survey. Through factor analysis, we identified main factors of GSCM pressure/drivers among Chinese manufacturers. Considering situations abroad and in China, we study on affecting mechanism of these factors and thus put forward a driving model of GSCM for Chinese manufacturers. Suggestions on how to implement GSCM among manufacturers are summarized in the end.
