摘要: Based on stochastic nonparametric envelopment of data, this paper estimates the shadow prices of agricultural water and the technical efficiencies, using an input-output data of 30 provincial units in Mainland China from 2002 to 2012. The results show that the average shadow price estimates for agricultural water range between 2.57 yuan/m 3 and 3.88 yuan/m 3; the estimated price elasticity of agricultural water is 0.12, and that improving technical efficiencies of the agricultural sector has a significant effect on the water demand …
