Abstract: With the realization mechanism of the cooperative supply chain of raw material green innovation as a focal point, this paper explores the interest demands and decision-making considerations of manufacturers and suppliers in raw materials green innovation, hoping to form a cooperative mechanism of raw materials green innovation, provide optimal decision for the manufacturers and suppliers during the process of raw materials green innovation, realize their profit maximization, and promote the healthy development trend of supply chain ecologicalization. The findings show that the establishment of the supply chain cooperative pattern for the green innovation of raw materials is feasible; producers can have extra profits through the support of green innovation, while the supplier can gain more profits if they accept the cooperation. However, whether the suppliers carry out green innovation depends on the degree of raw materials greenization brought about by green innovation and the output brought about by raw materials greenization. To sum up, the manufacturers can realize their profit maximization through the optimal green innovation supporting strategy, while the suppliers need to improve their efficiency of green innovation on such a base so as to gain greater earnings.
