Abstract: Exploring the key influencing factors of food security guarantee during the typical period is of significance for the development of cultivated land protection and agricultural policy. This paper aims at exploring the factors between 1999 and 2007 which was in the new period of cultivated land protection administration. Methods such as comparison, spatial and econometric analysis are used to analyze the change in cultivated land productivity which was the cause of the disparity between cultivated land area and grain output changes. Results show that farmers' willingness to grow grain which determines cultivated land use intensity is the key factor. The sustained improvement of the willingness in 2003-2007 was mainly resulted from the rise of grain market price. Meanwhile, direct subsidy merely inspired farmers' anticipation for the profit of grain growing at the beginning years of implementing this policy. In addition, suggestions on the development of cultivated land protection are proposed involving improvement of farmers' willingness to grow grain, optimization of inputs in grain growing and improvement of cultivated land protection models.
