完善绿色创新体系，大力发展绿色金融，切实提升企业创新绩效，是实现社会经济增长与绿色环保协调发展的关键所在。基于市场外部监督和信号传递理论，选取2010—2020年我国新能源上市公司面板数据，采取实证分析方法考察了绿色金融对企业创新绩效的影响，同时探讨了融资成本在绿色金融和创新绩效之间的中介效应。研究表明：(1)绿色金融发展能够有效促进企业创新绩效的提升，对新能源上市公司的创新绩效有明显的推动作用，绿色金融的发展对企业创新具有积极影响；(2)企业融资成本在绿色金融对企业绿色创新绩效的提升中发挥了中介效应。此外，相较于其他企业，绿色金融对企业创新绩效的提升作用在国有企业和东部地区企业的样本中更为突出。应完善绿色金融体系和以市场为主导的绿色创新体系，促进我国经济与社会不断向绿色创新方向转型升级。

Improving the green innovation system, vigorously developing green finance, and effectively enhancing corporate innovation performance are crucial for achieving coordinated socio-economic growth and environmental sustainability. Drawing upon market external supervision and signaling theories, this study empirically analyzes the impact of green finance on corporate innovation performance using panel data from new energy listed companies in China from 2010 to 2020. The mediating role of financing costs in the relationship between green finance and innovation performance is also explored. Results show that:(1) The development of green finance significantly promotes innovation performance in enterprises, particularly enhancing innovation in new energy listed companies;(2) Corporate financing costs play a mediating role in the relationship between green finance development and improved corporate innovation performance. Additionally, the positive influence of green finance on corporate innovation performance is more pronounced among state-owned enterprises and in eastern regions. It is recommended to improve the green finance system and market-driven green innovation systems, thereby accelerating China's socio-economic transformation toward "green innovation."
