An Analysis of the Agricultural Water Resources Utilization Efficiency Based on DEA and Malmquist Index: Taking the Water Receiving Area in Central Yunnan as an Example
In order to give full play to the utilization efficiency of agricultural water resources and realize the sustainable development of agriculture in the central Yunnan water receiving area, the output of main crops is selected as the output index, the agricultural water consumption, the comprehensive irrigation quota, the planting area of grain crops and the agricultural population are selected as the input indexes. Taking 2008 and 2018 as the cross-section data, the static data envelopment calculation analysis is carried out, and the Malmquist dynamic analysis is carried out based on the 2008-2018 data series. The results of static analysis show that the utilization efficiency of agricultural water resources in the whole and each water receiving area in Central Yunnan is invalid, and show a downward trend in recent years. The results of dynamic analysis show that TFP index of agricultural water resources utilization efficiency is not more than 1, the average value is 0.911 6, and it has been declining in the past 11 years. As an important factor in leading the utilization efficiency of agricultural water resources, technology directly determines the change rhythm of total factor productivity to a great extent. The key to improve the utilization efficiency of agricultural water resources is to strengthen the construction of water-saving and cooperate with reasonable resource allocation.
