Enhancement effect of rural digital development on agricultural total factor carbon productivity
In response to global climate change,the green benefits of digital transformation are attracting attention.As agriculture is the basis of the national economy and the second largest source of greenhouse gas emissions,how to simultaneously reduce carbon emis-sions and increase production in agriculture by means of digitalization is a key issue for China to achieve the'dual carbon'goals.Based on the panel data of 30 provinces in China from 2011 to 2020,this study constructed a comprehensive index of rural digitaliza-tion following the logic of'development foundation,development dynamics,and development results,'and applied the EBM-GML method to accurately quantify the agricultural total factor carbon productivity(ATFCP).The study found that:① Rural digitalization could increase ATFCP,and this finding still held after a series of robustness tests and endogeneity treatments.② Rural digitalization promoted technological innovation,scale operation,structural upgrading,industrial agglomeration,and non-farm employment,which in turn had an enhancing effect on ATFCP.③ The results of the heterogeneity analysis demonstrated that the positive effect of rural digita-lization on ATFCP showed a marginal decreasing effect,which could play a significant enhancing role in both high and low-green devel-opment level areas.In addition,the existence of a financial threshold for rural digitalization,which had a stronger effect in areas with high rural financial development levels,was a main constraint to digitalization in the process of promoting ATFCP.④ Spatial economet-ric analysis showed that there was a significant spatial effect between rural digitalization and ATFCP,and the long-term and short-term indirect effects were significantly positive,indicating that rural digitalization not only enhanced local ATFCP,but also positively affect-ed ATFCP in neighboring areas through technology diffusion.Based on this,we should further strengthen the dividend effect of rural digitalization by reducing carbon emissions and increasing production.We should also promote factor flow and technological applica-tion and enhance the development potential of rural digitalization by increasing financial investment and improving digital infrastruc-ture construction.At the same time,we should implement dynamic and differentiated digital rural development strategies,improve re-gional cooperation mechanisms,and promote the coordinated development of the digital economy in various regions.
