智慧城市建设对减污降碳协同治理的影响研究OACHSSCDCSTPCD

Collaborative promotion of pollution reduction and carbon reduction is an inevitable choice to fulfill its commitment to the dual carbon goals and achieve comprehensive green transformation of the economy and society.Based on the panel data of 210 prefecture level cities in China from 2006 to 2020,this paper uses the progressive double difference model to investigate the impact and internal mechanism of smart city construction on the collaborative governance of pollution reduction and carbon reduction,and further reveals the heterogeneous performance and spatial decay law of this effect.Research has found that:(1)the construction of smart cities can significantly promote the improvement of pollution reduction and carbon reduction levels in pilot areas,and its over-all effect shows a dynamic strengthening trend.(2)Promoting technological innovation,promoting industrial structure adjustment,and reducing energy consumption intensity are the three internal mechanisms that exert the aforementioned effects.(3)The im-provement effect of smart city construction on pollution reduction and carbon reduction is only significant in the eastern region,large-scale,non resource oriented,and regions with strong advantages in human,financial,and material resources.(4)The construc-tion of smart cities can promote the synergistic improvement of pollution reduction and carbon reduction levels in surrounding areas,manifested in a significant and gradually decreasing effect within a spatial range of 100 kilometers from the pilot city.The research conclusion can provide certain policy insights for China to continue and efficiently promote the construction of smart cities and a-chieve coordinated governance of pollution reduction and carbon reduction.
