A Study on the Carbon Emlssion Reduction Effect of Industrial Digitization Transformation:Empirical Evidence from Chinese Industry
Taking various industries of Chinese industry from 2000 to 2018 as the research object,this paper explores the influence and mechanism of industrial digital transformation on carbon emissions.The results indicate that industrial digital transformation in China can significantly promote carbon emission reduction,and this conclusion still holds after conducting robustness checks and endogenous tests.The mechanism test shows that the industrial digital transformation can exert the efficiency improvement effect and cooperation synergy effect,and promote carbon emission reduction by improving energy use efficiency and strengthening cooperation between up-stream and downstream enterprises in the supply chain.Heterogeneity analysis reveals that the carbon reduction effect of industrial dig-ital transformation exhibits industry and regional heterogeneity.In low-energy and low-emission industries,digital transformation shows a significant negative linear relationship with carbon emissions.In high-energy and high-emission industries,digital transformation ex-hibits a non-linear relationship with carbon emissions in the form of an inverted U shape.The promotion effect of digital transformation on carbon emission reduction is significantly higher in the eastern region compared to other regions,and the digital emission reduction effect shows a decreasing trend from the eastern region to the central region,the western region,and the northeast region.Therefore,we should strive to promote the application of digital technologies in industrial production processes,promote the sharing and transmis-sion of emission data among industries,and establish mechanisms for efficiency improvement and cooperative synergy.The digital transformation process of industries,especially high-energy industries,should be phased and implemented in different regions,provi-ding digital assistance for the orderly achievement of carbon neutrality.
