Abstract: 【Objective】 To explore the influence and internal logic between digital new quality productivity and agricultural green total factor productivity in Xinjiang. 【Methods】 Taking 2013-2021 as the study interval, this paper selected panel data from 14 regions and prefectures (cities) in Xinjiang, and used baseline regression model, intermediary model and threshold effect model to empirically analyze the impact of digital new quality productivity on agricultural green total factor productivity in Xinjiang. 【Results】 (1) Digital new quality productivity had a significant positive promoting effect on agricultural green total factor productivity in Xinjiang; (2) Land intensive management efficiency and land scale management efficiency play a significant intermediary effect in the process of digital new quality productivity affecting agricultural green total factor productivity in Xinjiang.when the threshold value is exceeded, the land intensive management efficiency further improves the promotion effect of digital new quality productivity on agricultural green total factor productivity in Xinjiang.(3) In different regions, digital new quality productivity has significant heterogeneity on the improvement effect of agricultural green total factor productivity. 【Conclusion】 Digital new quality productivity plays an increasing role in promoting agricultural green total factor productivity, but there are still insufficient forces in some regions, and it is still necessary to continue to promote the digitalization and intelligent development of agriculture.
