Abstract: This paper selected relevant indicators from the perspective of relative low carbon and absolute low carbon,and used the entropy weight method to evaluate the low carbon development level of agricultural production in 31 prefecture-level cities in the three northeastern provinces,and focused on technological progress and environmental regulation.It analyzed the influencing factors of development level empirically.The results showed that: the overall average level of the three northeastern provinces and the low-carbon development level of agricultural production in the prefecture-level cities were on the rise as a whole.From the perspective of spatial distribution,the growth rate of low-carbon agricultural production in each city had the characteristics of local spatial aggregation; from the perspective of the temporal and spatial evolution trend,cities with a higher level of low-carbon development extend from the southeast and northeast as the source points over time.In the process of improving the level of low-carbon development,technological progress had an important positive effect on the improvement of the level of low-carbon development,and government environmental regulation policies had a negative impact on the level of low-carbon development by negatively affecting scale efficiency.
