Abstract Based on the survey data of 697 farmer households in Heilongjiang Province, this paper investigates the soil and water resources utilization methods and the matching degrees. Then it discusses the influence of soil and water resources utilization methods on technical efficiency of major producers of grain by adopting super-efficiency DEA-Tobit two-stage model. Results show that: 1) The scale of land management of major grain producers falls mostly between 100-300 mu, but it shows a trend towards large-scale. With the expansion of scale, the land leveling grows more active. However, irrigation is still dominated by traditional irrigation, and there are signs of regression, so the land and water resources are badly matched. 2)The technical efficiency of major grain growers is not high, and there is much room for improvement. 3)There is a “U” curve variation law between land management scale and the technical efficiency of major grain growers. The structures of land use, the condition of the water conservancy facilities in the farmland and the way of irrigation have significant positive effects on the technical efficiency of major grain producers.
