To help enterprises utilize digital technologies to increase their green innovation awareness and behavior and further clarify the “black box” of this process, this study first develops a theoretical framework to explain the mechanism of the functional attributes of digital technology, stakeholder value co-creation, and enterprise green innovation. Data are subsequently gathered from 342 manufacturing enterprises, and the meditation and moderation hypotheses are empirically analyzed using hierarchical regression and the bootstrapping method. A robustness test is conducted via data grouping. The findings indicate that digital technology openness and affordance have a positive effect on green product innovation and process innovation through value co-creation between businesses and stakeholders. Additionally, digital technology self-growth positively moderates the indirect effect of digital technology affordance on the green innovation of enterprises through value co-creation.
