Digital Leadership,Low-Carbon Development,and Urban"Emission Reduction and Efficiency Enhancement"
摘要
Abstract
Leading urban low-carbon transitions with digitalization and coordinating the construction of Digital China with the achievement of the"dual carbon"strategic goals are crucial measures for promoting high-quality economic development and realizing Chinese-style modernization. Based on panel data from 279 prefecture-level cities between 2006 and 2021,this paper takes the"National Big Data Comprehensive Pilot Zone"strategy and the dual pilot construction of low-carbon cities as quasi-natural experiments,and employs a multi-period difference-in-differences method to empirically study the effects and mechanisms of the"dual pilot"policy on urban emission reduction and efficiency enhancement.The findings indicate that the"dual pilot"policy promotes urban emission reduction and improves green total factor productivity,that is,exerting the effect of urban emission reduction and efficiency enhancement;agglomeration effects and factor effects are important mechanisms for the"dual pilot"policy to achieve urban emission reduction,while technological effects are important mechanisms for achieving urban efficiency enhancement;environmental regulation,public environmental attention,and local government competition play positive moderating roles in the policy effects.Further research shows that the"dual pilot"effect is superior to that of the"single pilot"policy.The"National Big Data Comprehensive Pilot Zone"performs outstandingly in efficiency enhancement,while the low-carbon city policy performs outstandingly in emission reduction.Only the synergistic linkage of the two policies can release the dual dividend of emission reduction and efficiency enhancement. This study provides a reference for how to balance emission reduction and efficiency enhancement in the low-carbon transition of cities,and offers new empirical evidence and policy insights for policy coordination and cooperation.关键词
