Abstract By introducing the innovation process of green technology, this study constructs a green supply chain composed of a single shared supplier and two manufacturers, and uses a stochastic stopping model to describe the impact of green technology innovation on green R&D investment decisions. Based on the differential game, the green R&D investment decisions and coordination of supply chain are researched. The results show that: a higher probability of success of technological innovation and a higher rate of greenness improvement can motivate enterprises to increase green R&D investment before successful technological innovation, and then improve product greenness. The impact of green technology innovation on manufacturers’ green R&D investment is related to the intensity of green competition. The bidirectional cost-sharing contract can coordinate the supply chain, in which the share ratio of the shared supplier to the manufacturers’ green R&D input cost is negatively correlated with the intensity of green competition, and the sum of the share ratio of the two manufacturers to the shared supplier’ s green R&D input cost is determined.
