数字经济对种植业碳排放的影响OA

To explore the internal impact mechanism of the digital economy on carbon emissions from the planting industry is conducive to promoting the low-carbon transition of the planting industry.Based on the panel data of 30 provinces,autonomous regions and municipalities(directly under the central government)in China(excluding Xizang Autonomous Region,Hong Kong,Macao and Taiwan regions)from 2011 to 2023,this paper analyzed the role of the digital economy in the whole process of social reproduction from the planting industry,and used the fixed-effect regression model,mediation effect model,and threshold effect model to empirically examine the internal relationship between the digital economy and carbon emissions.The results showed that:the digital economy significantly inhibited carbon emissions from the planting industry,with distinct regional heterogeneity and carbon source heterogeneity,the inhibition effect was favorable in the central region,western region,major grain-producing areas and hilly areas,and the emission reduction effect performed well in terms of chemical fertilizers,pesticides,agricultural plastic films and tillage;the mediation effect results indicated that the digital economy achieved carbon emission reduction mainly by promoting large-scale operation and the development of agriculture-related finance,and this inhibition effect was affected by the local development level of the digital economy;the threshold effect results indicated that the impact of the digital economic development on carbon emissions from the planting industry exhibited nonlinear characteristics.In the early stage of digital economic development,it inhibited carbon emissions from the planting industry.However,as development progressed to the intermediate stage,further advancement of the digital economy led to an increase in carbon emissions from the planting industry.When the digital economy entered a higher advanced stage,the emission reduction effect on the carbon emissions from planting industry re-emerged.Therefore,policies should be formulated in the following four aspects,such as increasing investment in digital infrastructure in rural areas,strictly controlling carbon emissions,promoting large-scale planting,and enhancing regional coordination and cooperation.
