Green innovation ecosystem value realization is crucial to building an environmentally friendly society and achieving the “dual-carbon” goal, and trust transfer provides a new perspective. This paper divides the participating subjects in the green innovation ecosystem into technology R&D platform, promotion and service group, consumption, and application group. It constructs a game model of the trust transfer mechanism’s evolution to examine each key factor’s impact on the value realization decision. The conclusions are as follows: (1) The initial willingness of the three groups does not affect the stabilization strategy of ecological value realization, and the higher the degree of green technology innovation and application, the more perfect the trust transfer network, the higher the benefits generated by value realization of innovative subjects. (2) Subsidized incentives for technology R&D platform by promotion and service group can facilitate the ecosystem value realization process. At the same time, excessive monitoring can discourage technology R&D platform from conducting green technology R&D. (3) The consumer application group is an essential “navigator,” providing a particular direction guidance for green technology R&D, in which the consumer application group chooses to accept the green product strategy will promote the improvement of the trust transmission network and the value realization process, and on the contrary, it will have an inhibitory effect. The study’s conclusions provide a vital decision-making basis for green innovation ecosystems’ high-quality and sustainable development.
