The impact of digital economy on industrial carbon emission performance:Threshold effect analysis of heterogeneous environmental regulations
Given the backdrop of heterogeneous environmental regulations,investigating the influence of the digital economy on industrial carbon emission performance assumes paramount significance.Leveraging panel data spanning 2011 to 2020 from 30 provinces,and employing administrative order,market incentive,and public participation environmental regulations as threshold variables,we construct a bi-directional fixed-effect model and a panel threshold regression model to scrutinize this relationship.Our findings reveal that while the digital economy can enhance industrial carbon emission performance,its efficacy is contingent upon the regulatory landscape.Across different types and intensities of environmental regulations,the impact of the digital economy varies.Regional analysis underscores this variability:in the eastern region,the digital economy's impact peaks under the threshold of market-incentive environmental regulation,transitioning from inhibitory to promotional effects pre-and post-threshold.Conversely,in the central region,the digital economy's impact peaks under the threshold of public participatory environmental regulation,transitioning from promotional to inhibitory effects pre-and post-threshold.In western China,the digital economy's impact peaks under the threshold of administrative order environmental regulation,exhibiting its strongest effect within the threshold.Consequently,policymakers are urged to craft a diverse environmental regulatory framework and leverage digital economy development to enhance industrial carbon emission performance,tailored to regional characteristics.
