城市绿色治理与减污降碳协同效应分析OA

Energy structure transition is one of the most critical strategic tasks in China at present.The New Energy Demonstration City Policy,as a core policy tool for energy structure transformation,is not only an important testing ground for promoting clean energy innovation and industrial upgrading,but also a key means of urban green governance.Based on the data of coordinated pollution reduction and carbon reduction in 272 prefecture-level cities from 2005 to 2022,this study empirically tested the coordinated pollution reduction and carbon reduction effect of urban green governance using methods such as the difference-in-differences model,non-desired super-efficiency SBM model,coupling coordination degree model,spatial Durbin model,kernel density estimation,and text analysis.The research found that the New Energy Demonstration City policy has significant coordinated pollution reduction and carbon reduction effects,which are verified through a series of robustness tests such as propensity score matching and placebo tests.Mechanism research found that the New Energy Demonstration City policy promotes coordinated pollution reduction and carbon reduction by stimulating green technological innovation and strengthening environmental regulation.Heterogeneity analysis shows that in the eastern cities with high levels of non-resource endowment,scientific and technological level,and marketization,the coordinated pollution reduction and carbon reduction effect of the policy is more significant.Finally,the New Energy Demonstration City policy has a spatial spillover effect,that is,the diffusion of new energy technology and industrial linkages can break geographical boundaries and promote coordinated pollution reduction and carbon reduction in surrounding cities.The above research provides insights for the deployment of new energy policies,accelerating urban energy transformation,and coordinated pollution reduction and carbon reduction.
