Research on the Utilization Efficiency of Agricultural Water Resources in Tianjin based on DEA Model

Improving the efficiency of agricultural water resources is an important measure to enhance the comprehensive strength of agriculture and build a water-saving society. In this context, this paper takes the efficiency of agricultural water resources utilization in Tianjin based on DEA model from 2008 to 2017 as the research object, and uses the input index of agricultural water consumption, annual precipitation, effective irrigation area, irrigation water consumption, agricultural labor force required under the unit effective irrigation area, and the total power of agricultural machinery required under the effective irrigation area of the unit. The output index of total agricultural output value and unilateral aquatic quantity are selected The results show that Tianjin needs to reduce the proportion of agricultural water use according to local conditions, speed up the application and transformation of agricultural water-saving achievements, and increase the proportion of technology input to replace labor input, so as to further improve the efficiency of agricultural water resources utilization.
