Abstract

Study on the production of agricultural water resources and input-output efficiency of grain production from 2005 to 2012 of Henan Province. Using the investment orientation of DEA method to calculate technical efficiency and scale efficiency of input indicators. The results show that agricultural water and other indicators have factor substitution. If the grain production is technical efficiency and scale efficiency,improving the efficiency of the labor force,the power of agriculture machinery,pesticide and fertilizer,and stabilizing or reducing the amount of agricultural water,can guarantee the grain production yield.
