Toward green development of the Belt and Road Initiative is an important measure to address global environmental risks and promote sustainable development.Based on the panel data of prefecture-level cities in China from 2010 to 2022,evaluate the impact and mechanism of the Belt and Road Initiative on green innovation in Chinese cities along the route by constructing a difference-difference model.The results show that:the Belt and Road Initiative significantly promotes the green innovation of Chinese node cities along the route,and it is still significant after a series of robustness tests,such as parallel trend,placebo,PSM-DID,and exclusion of concurrent policy interference.In terms of impact mechanism,the implementation of the Belt and Road Initiative can improve the quality of the business environment and the development level of green finance of Chinese cities along the route,and thus enhance their levels of green innovation.Heterogeneity analysis shows that the promoting effect of the Belt and Road Initiative on green innovation in Chinese cities along the route is more significant in the"Road"region,central and eastern regions and areas with high environmental regulations.Further research finds that network infrastructure construction plays a positive regulatory role in green innovation of Chinese cities along the Belt and Road.The research conclusions are not only beneficial to the realization of green and high-quality development of the Belt and Road,but also provide theoretical and empirical basis for the government to give full play to the role of the Belt and Road Initiative and formulate urban green innovation development strategies.
