Agricultural labor productivity growth means related to the sustainability of agricultural growth. This paper analyzed China ’s major grain producing areas agricultural labor productivity growth path. Relative to the increased in productivity per unit of land, the greater output came from the value of per unit labor. Its essence was the result of reduced labor
