[Impact and Mechanism of Rural Digital Economy Development on Agricultural Low-carbon Transformation].

As a vital support for rural revitalization and low-carbon development strategies， the role of rural digital economy development in promoting agricultural low-carbon transformation has become increasingly prominent. Based on panel data from 30 provinces in China during 2010-2023， this study constructs a two-way fixed effects model to systematically evaluate the impact of rural digital economy development on agricultural low-carbon transformation. Furthermore， it explores the underlying mechanisms from the perspectives of mediation effects， threshold effects， and regional heterogeneity. The results show that： ① Rural digital economy development significantly promoted agricultural low-carbon transformation， and this conclusion remained robust across various tests. ② Mechanism analysis revealed that rural digital economy development advanced agricultural low-carbon transformation primarily by enhancing regional economic development. ③ Threshold effect tests indicated that the promotive impact of rural digital economy development became stronger with higher levels of rural human capital， while the effect failed to be effectively triggered under weak government environmental governance. ④ Regional heterogeneity analysis revealed significant disparities in the impact of rural digital economy development on agricultural low-carbon transformation across the two sides of the "Hu Huanyong Line."
