Abstract: Taking China’s 30 provinces (autonomous regions and municipalities) as research objects, the fixed-effects model and mediation effect model were constructed to empirically test the impact of digital new quality productivity and high-quality agricultural development on agricultural total factor carbon productivity from 2012 to 2021. The results showed that the agricultural total factor carbon productivity had a steady growth trend from 2012 to 2021, and the agricultural total factor carbon productivity in central China was higher. The digital new quality productivity had a significant promoting effect on the agricultural total factor carbon productivity. Digital new quality productivity significantly positively impacted agricultural total factor carbon productivity by empowering high-quality agricultural development. Furthermore, heterogeneity analysis revealed that the digital new quality productivity had a more significant promoting effect on agricultural total factor carbon productivity in low digitalization level regions and central regions. It was suggested to establish a regional heterogeneous digital technology promotion system, strengthen the technological innovation driven by high-quality development of agriculture, and improve the dynamic monitoring mechanism of agricultural carbon productivity.

Key words: digital new quality productivity, high-quality development of agriculture, total factor carbon productivity in agriculture, fixed effect model, mediation effect model
