Abstract: China’s agricultural water consumption accounted for more than 60% of the total water consumption in 2016. Water has become an important guarantee for national agricultural safety. Improving agricultural production efficiency is conducive to reducing agricultural water consumption. Firstly, this paper uses the Super-SBM model of non-expected output to measure the agricultural production efficiency of 30 provinces in China during the period of 1998-2015. Then, the paper applies non-parametric kernel density estimation to present the agricultural production efficiency and agricultural water consumption in some important years and months. Finally, the threshold model by Hansen is used to examine the threshold effect of agricultural production efficiency on agricultural water consumption. The result shows the inverted “U”-shaped trend of China’s agricultural production efficiency, and inter-provincial differences were narrowing. Agricultural water consumption decreased first and then rose with the expanded gaps among provinces. Improving agricultural production efficiency is an effective way to reduce agricultural water consumption. Agricultural production efficiency exerts threshold effect in controlling agricultural water consumption which shows “N”-shaped trend. The increase of the proportion of grain crops, rural labor force and income of rural residents can effectively inhibit the increase of agricultural water consumption. Water resources endowment, water investment and irrigated area are positively correlated with agricultural water consumption. What’s more, the effect of peasants’ education level is not significant.

Key words: agricultural production efficiency, agricultural water consumption, kernel density estimation, Super-SBM, threshold effect
