Impact of agricultural subsidies on Xinjiang cotton irrigation water efficiency:the mediating effect of farmers'arable land operation scale
Water resources are a prerequisite constraint for agricultural development,and their utilization efficiency has a significant impact on economic and social development.Effectively measuring the impact of agricultural subsidies on irrigation water use efficiency is important for assessing agricultural subsidy policies and improving water use efficiency.To assess the impact of agricultural subsidies and farmland operation scale on cotton irrigation water use efficiency on the basis of research data of 312 farm households in Xinjiang,China,in 2023,we used the transcendental logarithmic stochastic frontier production function model and analyzed the nonlinear impacts of agricultural subsidies and farmland operation scale on the irrigation water use efficiency of Xinjiang cotton with the Tobit model.The results showed that the average cotton irrigation water use efficiency of the farmers was 0.560,and the loss of efficiency was relatively serious.The agricultural subsidies and farmland operation scale of the farmers had a direct inverted"U"effect on the cotton irrigation water use efficiency.The farmland operation scale had a mediating effect on the impact of agricultural subsidies on cotton irrigation water use efficiency.The study shows that,to improve irrigation water use efficiency in the context of the coexistence of severe water scarcity and low water use efficiency in Xinjiang,policy efforts should be increased in terms of promoting moderate agricultural subsidies and guiding farmers to operate on an appropriate scale.
