      abstract = {We build the influence function empirical model of China's  grain production at the present stage in view of the  factors influencing direct grain subsidies, using  Cobb-Douglas production function model. And we estimate the  elasticity coefficient of impact of China's direct grain  subsidies on grain yield, using the panel data pertaining  to 29 provinces in the period 2004-2007; comparatively  analyze the validity and limitation of policy factors of  direct grain subsidies on China's grain yield. The results  show that at the present stage, the elasticity coefficient  of impact of China's direct grain subsidies on grain yield  is 0.0023, and under the existing subsidy system and level,  direct grain subsidies play a positive role in increasing  grain yield, but the role is limited; the elasticity  coefficient of impact of the food price on grain yield is  much larger than that of impact of direct grain subsidies  on grain yield. Therefore, the government should strengthen  and improve direct grain subsidy policies; in the mean  time, pay full attention to the use of market mechanism to  consolidate the basic role of the food price in promoting  food security to a great extent.},
