Abstract：
Using the data of 589 wheat growing households in Henan, and taking wheat output per unit of land, technical efficiency and net income per unit of land as measurements of land productivity, this paper deduces the path selection of moderate scale for the exclusive grain rotation and non-grain rotation respectively, from the perspective of maximizing of output and income. The findings are as follows. Firstly, the wheat output per unit of land is relatively stable in Henan under both rotations. The technical efficiency takes a dramatic downward turn when land area exceeds a certain scale, and the average net income per unit of land for single season wheat and annual crops decreased from positive values to negatives. Secondly, the moderate scale of wheat growing in Henan eventually converge to 200-400 mu under the goal of stabilizing wheat production and increasing income. The “moderate” scale can achieve a win-win goal of stable grain growth and income raise. Thirdly, large-scale and ultra-large-scale operation not only reduce the output efficiency, but also lead to a negative net income. It is of practical significance to establish a “moderate” scale detection mechanism to avoid the blind choices of scales.
