Abstract： To accelerate green technological innovation and foster new growth drivers for sustainable development is crucial for achieving the“dual carbon”goals. As a vital vehicle for the difusion of green technologies，the structural characteristics and evolution mechanisms of patent cooperation networks demand systematic exploration. This study employs a multi-modal network analysis framework based on joint patent data from China's green technology sector spanning 2O08-2023. Specifically，the framework utilizes applicant data to construct a collaborative network of entities，quantifying historical collaboration features of nodes. It combines KeyBERT for extracting patent knowledge elements to build a bipartite network of entities and knowledge，thereby quantifying the knowledge attributes of nodes. The study employs a random exponential graph model to investigate the impacts of endogenous network structures，historical collaboration patterns，and knowledge attributes on the evolution of green technology patent cooperation networks.The findings reveal that selectivity and transitivity play significant roles in promoting network formation. Knowledge diversity has a positive and significant impact on network development，while collaboration depth exhibits a negative and significant influence. The effects of partner diversity and knowledge uniqueness vary across network development stages，showing partial significance. These conclusions provide quantitative evidence for optimizing the green technology cooperation ecosystem and advancing the transformation of innovation network governance paradigms under the dual carbon goals.
