Promoting environmental innovation through environmental regulation is a key measure for cities to reduce environmental pressure; however, the role of environmental regulation in environmental innovation is controversial. This study used the number of environmental patent applications to measure urban environmental innovation and analyzed the role of urban environmental regulation on urban environmental innovation with the help of the spatial Durbin model (SDM). The results showed that: (1) From 2007 to 2017, the number of environmental patent applications in China has grown rapidly, and technologies related to buildings dominated the development of China's environmental innovation. (2) Although the number of cities participating in environmental innovation was increasing, China's environmental innovation activities were highly concentrated in a few cities (Beijing, Shenzhen, and Shanghai), showing significant spatial correlation and spatial agglomeration characteristics. (3) Urban environmental regulation had a positive U-shaped relationship with urban environmental innovation capability, which was consistent with what the Porter hypothesis advocates.
通过环境监管推动环境创新是城市减轻环境压力的关键措施；然而，环境监管在环境创新中的作用存在争议。本研究使用环境专利申请数量来衡量城市环境创新，并借助空间杜宾模型（SDM）分析了城市环境监管对城市环境创新的作用。结果表明：（1）2007 年至 2017 年，中国的环境专利申请数量迅速增长，建筑相关技术主导了中国环境创新的发展。（2）尽管参与环境创新的城市数量不断增加，但中国的环境创新活动高度集中在少数几个城市（北京、深圳和上海），表现出显著的空间相关性和空间集聚特征。（3）城市环境监管与城市环境创新能力之间呈正 U 型关系，这与波特假说所主张的一致。
