Abstract:
Using the super-efficiency SBM model and the Malmquist index，agricultural productivity in the northwest region from 2008 to 2022 from both static and dynamic perspectives was analyzed.By decomposing production efficiency and conducting projection analysis，the causes affecting production efficiency was identified，in order to enhance agricultural productivity in the northwest region，promote agricultural development，and contribute to rural revitalization.The results showed that the overall northwest region had not achieve DEA efficiency，indicating room for improvement in the utilization of agricultural resources.The main reason for the lack of DEA efficiency was low scale efficiency，suggesting diminishing returns to scale in agricultural production and the absence of scale effects.Further projection analysis on input factors revealed that total sown area of crops and effective irrigated area had the highest redundancy.The total factor productivity in the Northwest region grew at an average annual rate of 11.5%，with technological progress being the largest contributor.This indicated that the improvement in total factor productivity in the Northwest region mainly relied on advancements in agricultural technology.
