The environmental and social concerns in managing agribusiness are increasing in Thailand. Green supply chain management (GSCM) is becoming more significant tool to improve performance of the process and products according to the environmentally friendly regulations. However, there is a question associating with how to evaluate the green performance of supply chain. This paper applies two-stage DEA model for measuring the network performance of the growers and processors in longan supply chains. The major result represents that the high level of economic efficiency of longan supply chains does not ensure the high score of green performance efficiency. The finding of this research leads to the policy making of the government agencies in promoting the green supply chain of longan to create value added of products and enhance competitiveness, as well as encourage the environmental awareness of the growers and processors.
