The impact of industrial digitalization on reducing air pollution and carbon emission:Perspectives from the productivity paradox
Digital economy has played an important role in the process of industrial green trans-formation,which is of great theoretical and practical significance to explore the pollution and carbon dioxide emission reduction effects and impact mechanisms of industrial digitalization.Based on the input-output table of China's between 1991 and 2008 provided by the Eora global supply chain database and the matching industrial environment and energy consumption satel-lite accounts,this paper empirically investigates the possible impact and mechanism of digital investment on carbon dioxide emissions and pollution emissions from the perspective of factor productivity.Empirical results suggest that digital investment has a non-linear effect on carbon dioxide emissions and pollution emissions,which is robust after mitigating the endogenous nature of digital investment.Mechanism analysis shows that the nonlinear relationship between digital investment and pollution reduction and carbon dioxide reduction are driven by the level of digital investment and the industrial factor productivity.During the sample period investigated in this paper,empirical results verify the existence of"productivity paradox"of digital economy,which is mainly because the marginal benefit of digital investment in the digital infrastructure indus-try is less than the marginal cost,and the relationship between factor productivity and digital investment is"U"-shaped,while there is an inverted"U"-shaped relationship between factor pro-ductivity and emissions.The digital investment and factor productivity during the sample period are both at a low level,as a result,digital investment promotes pollution reduction and carbon dioxide reduction of industry through the effect of"negative negative gain positive".Moreover,heterogeneity analysis shows that digital investment has a stronger pollution and carbon dioxide reduction effect on medium and high energy consumption industries,manufacturing industries,resource-based industries,and when the industry is in a higher export dependence,and a series of robustness tests suggest that the conclusions of this paper are robust.The findings of this paper provide an important policy reference for formulating a digital economy development strategy to serve the achievement of high-quality development economy and strengthening green supply chain management.
