[Impact of Digital Technology on Agricultural Carbon Productivity Under the Dual-carbon Goal]

Enhancing agricultural carbon productivity under the dual-carbon goal is important for mitigating global climate change, and the development of digital technology provides a new impetus for the low-carbon transformation of agriculture and the green development of the economy. Using the panel data of 30 provinces in China from 2013 to 2023, the projection pursuit model based on the accelerated genetic algorithm and the emission coefficient method are used to measure the development levels of rural digital technology and agricultural carbon productivity, respectively, and the panel fixed-effect model and spatial Durbin model are used to study the impact of digital technology development on agricultural carbon productivity. The results showed that: ① The development of digital technology in China had a spatial distribution pattern of decreasing gradient from east to west, and the agricultural carbon productivity in the southwest region had a high-high clustering pattern, with both showing an increasing trend year by year. ② The development of rural digital technology had a significant effect on the improvement of agricultural carbon productivity. ③ The heterogeneity test showed that the effect of digital technology on the improvement of agricultural carbon productivity was "western > central > eastern" and "balanced grain production and marketing area > main grain production area > main grain marketing area." ④The development of digital technology had a positive spatial spillover effect on agricultural carbon productivity in neighboring regions, with intensive spillovers within 300 km and detectable effects extending to 700 km of the spillover effect.
