Has the Deepening of Digital Trade Rules Brought Environmental Benefits:An Analysis Based on the Perspective of Embodied Carbon Emissions in Trade
Based on MRIO and environment account data of 42 major economies in the world from 2000 to 2014,this paper empirically investigates the impact of the deepening of digital trade rules on the intensity of embodied carbon emissions in export.The research shows that:(1)the deepening of digital trade rules can significantly reduce the intensity of embodied carbon emissions in export of the contracting party,and this conclusion passes a series of robustness tests;(2)mechanism analysis indicates that the deepening of digital trade rules exerts inhibition effect on the intensity of embodied carbon emissions in export mainly through strengthening bilateral value chain correlation,enhancing service factor inputs substitution of manufacturing industry and promoting technology spillover of digital intermediate goods imports;(3)heterogeneity analysis reveals that data flow clauses have the strongest effect on the intensity of embodied carbon emissions in export,followed by trade environment clauses and privacy protection clauses;the overall improvement of digital trade clauses exerts more significant carbon emission reduction effect on pollution-intensive industries and non-technology-intensive industries.Based on the research findings,this paper provides policy recommendations for advancing the signing of high-standard digital trade rules,improving the quality of opening up and promoting the construction of digital economy.
