Abstract:

New agricultural operators are the main force of agricultural development in China. Based on the field investigation data of the North China Plain area, this study selected winter wheat as the research object, applied a stochastic frontier analysis (SFA) model to calculate the irrigation water use efficiency of winter wheat with different agricultural operators, and used the Tobit model to explore the factors that affect the irrigation water use efficiency of different subjects. The study found that there are great differences in irrigation water use efficiency of smallholder farmers, large grain growers, family farms, and agricultural cooperatives, and the irrigation water use efficiency values of farmers in family farms and agricultural cooperatives are mostly concentrated at the level of more than 70%. On the other hand, smallholder farmer irrigation water use efficiency values are concentrated at the level of 10% to 30%. Combined with the technical efficiency of various agricultural operators, we can see that the irrigation water use efficiency of smallholder farmers and new agricultural operators have a certain space to improve; significant differences exist in the factors that affect irrigation water use efficiency of smallholder farmers and new agricultural operators, such as the level of education and labor force; and the proportion of agricultural income, water cost, and adoption of advanced irrigation technology have a positive impact on the irrigation water use efficiency of all agricultural operators. Among the new agricultural operators, farmers’ age, irrigation area, irrigation facilities, and training measures can improve their irrigation water use efficiency, but have no significant impact on the irrigation water use efficiency of smallholder farmers. Smallholder farmers should be an important target to promote the application of water-saving irrigation technology and improve the efficiency of irrigation water use. Measures such as speeding up the transformation of traditional farmers to a new type of agricultural operator and increasing the development of public services will help to improve the efficiency of irrigation water use.

Key words: smallholder farmers, new agricultural management entities, irrigation water use efficiency, stochastic frontier analysis (SFA), North China Plain
