North-South cooperation in green innovation activities is an essential avenue for promoting global climate governance. This study examines the impact of technological overlap on the scale of international cooperation in environmental technologies (ETs) between Chinese and foreign geographical units. The results show that technological overlap significantly increases the scale of international cooperation in ETs. The main international cooperation partners are located in the G7 countries, with the United States being the most significant partner. Technological overlap has not only promoted China to send many patent inventors to other countries but also encouraged China to introduce more foreign inventors. Further research reveals a significant interaction effect between the scale of existing inventor cooperation, local technological advantages, and technological overlap, which expands the scale of international cooperation. This paper calls for strengthened ET cooperation between developed and developing countries to address climate change.
南北在绿色创新活动方面的合作是促进全球气候治理的重要途径。本研究考察了技术重叠对中外地理单元之间环境技术国际合作规模的影响。结果表明，技术重叠显著增加了环境技术国际合作的规模。主要国际合作伙伴位于七国集团国家，其中美国是最重要的合作伙伴。技术重叠不仅促使中国向其他国家派出众多专利发明人，也鼓励中国引进更多外国发明人。进一步研究揭示了现有发明人合作规模、本地技术优势与技术重叠之间存在显著的交互效应，这扩大了国际合作规模。本文呼吁加强发达国家和发展中国家之间的环境技术合作以应对气候变化。
