This study takes the agricultural resource utilization efficiency of Gansu Province and its cities(prefec-tures)during 2008-2017 as the research object,evaluates the efficiency by using data envelopment analysis(DEA),mathematical statistics and literature research methods,selects 10 input indicators and 3 output indicators of ag-ricultural production,and then calculates the comprehensive efficiency,technical efficiency and scale efficiency of agricultural resources utilization in Gansu from 2008 to 2017,the redundancy of the input was analyzed by com-bining with the redundancy value,and projection analysis was applied to improve the input and allocation of agri-cultural resources.For the temporal characteristics of agricultural resource utilization efficiency in Gansu,the re-sults show that the utilization efficiency is relatively low and fluctuates over time while gradually stabilizing,the comprehensive efficiency increased from 0.857 to 1,with values that were not 1 in 2008,2009,2010,2011,2012 and 2015,showing a relatively ineffective utilization state,and the utilization efficiency had a hysteresis effect on the implementation of policies.Meanwhile,the spatial distribution characteristics indicate large regional differ-ences in utilization efficiency among the cities and prefectures,all of the cities can be divided into four categories according to their different comprehensive efficiency levels:the best(1.00),the second best(0.98-1.00),the lower(0.90-0.98)and the lowest(<0.90),and the corresponding characteristic agricultural development regions were divided based on their actual situations;the redundancy of agricultural input factors still exists,especially in eco-logical factors such as climatic resources,agricultural fertilizer usage and agriculture practitioners;while the tech-nical efficiency had obvious restrictions on the comprehensive efficiency.In summary,the input-output efficiency of agricultural resources in Gansu is relatively low overall,the unbalanced regional development of utilization effi-ciency is obvious,and agricultural development is greatly constrained by ecological and technical factors.Therefore,the key to improving this situation lies in the integration of agricultural support funds to develop agricultural facili-ty construction,adjust the agricultural input and industrial structure,actively promote the application of science and technology,vigorously develop regional characteristic agriculture,and create ecological and civilization agriculture.
