为推动绿色技术创新扩散，缓解能源短缺与环境恶化对社会经济发展的双重压力。基于创新主体与需求主体的利益交互关系，将绿色技术创新扩散分为两阶段，分别为绿色创新技术在集群企业间扩散与绿色创新产品在市场消费者间扩散，且考虑扩散群体网络结构的差异性，构建由博弈主体、演化规则和网络结构三要素组成的供需端异质网络环境下绿色技术创新扩散三阶段博弈模型，并选取典型案例进行数值仿真分析。研究表明：当政府激励绿色技术创新在集群企业间和市场消费者间扩散时，最优补贴阈值分别受集群组织结构和绿色创新企业数量显著影响，且激励效用均存在边际递减现象；相较于边缘企业，核心企业采纳绿色创新技术的决策行为受集群绿色创新组织结构影响，并对政府经济补贴与绿色创新技术成熟度表现出更高的敏感度；绿色创新产品的市场需求遵循价格竞争原则，降低其市场价格有利于驱动其扩散，同时绿色创新产品的技术成熟度以及释放的绿色效益也是影响其扩散的主要因素；绿色技术创新扩散过程的稳定性受扩散群体网络结构影响，降低绿色创新技术研发成本或绿色创新产品价格能够有效提高创新扩散的稳定性。研究结论得到有利于绿色技术创新扩散的稳定条件以及特定条件下的政府补贴边界，对于提升绿色技术创新扩散效率具有理论与实践指导意义。

This study aims to promote the diffusion of green technological innovation，and mitigate the dual pressures of energy shortages and environmental degradation on socio-economic development. We categorized the diffusion of green technological innovation into two stages： diffusion among cluster enterprises and diffusion of green innovation products among market consumers，based on the interactive relationship between innovation subjects and demand subjects. Given the heterogeneity of the diffusion network，a three-stage game model for diffusion of green technological innovation under heterogeneous supply-demand network environments was constructed，consisting of game players，evolutionary rules，and network structures. A representative case study was chosen for numerical simulation analysis. The research showed that government incentives for dissemination of green technological innovation among cluster enterprises and adoption of green products by consumers are notably affected by the cluster's organizational structure and the number of green innovative enterprises，respectively. Furthermore，the impact of these incentives diminishes as their scale increases，reflecting the principle of diminishing marginal returns. Compared to peripheral enterprises，core enterprises are more heavily influenced by the cluster's green innovation organizational structure when deciding to adopt green technology，and they demonstrate greater sensitivity to government subsidies and the maturity of green technology. Market demand for green products follows the principle of price competition，meaning that lowering prices can stimulate their adoption. Furthermore，technological maturity and environmental benefits of green products are key factors influencing their adoption. The stability of the green technology dissemination process is affected by the network structure of the dissemination group. Lowering research and development costs or product prices can effectively enhance this stability. The research findings have identified stable conditions favorable to the diffusion of green technological innovation and defined optimal government subsidy boundaries under specific conditions，and they will provide theoretical and practical guidance for enhancing diffusion efficiency.
