Abstract：Most agricultural production efficiency evaluations of irrigation district are based on single input and output index now. We used data envelopment analysis(DEA)method and set the input and output index system which can represent the characterization of production efficiency, after that we compared the relative production efficiency of 35 irrigation districts in Jiangsu using the CCR model as an example. Results showed that the comprehensive efficiency of Jiangsu province was not high; The differences between irrigation area were large; The average value of the comprehensive efficiency of Jiangsu was 0.634; Three irrigation districts were DEA effective; The popularization and utilization of agricultural production technology in different region were at the same rate; The imbalance of relative production efficiency of irrigation districts was mainly caused by the unreasonable production scale; We can increase the production efficiency of DEA ineffective irrigation area by reducing the input;The effective irrigation area, water resources and agricultural population we can saved in all the DEA ineffective irrigation districts were accounts for 20.7%,13.3% and 9.4% respectively by improving production efficiency when compared with the input. The comparison of the relative DEA efficiency can provide a new method for irrigation production efficiency improvement and the calculation of agricultural water saving potential.
