Abstract:

Abstract: This research takes SFA measure methods to calculate and estimate the technical efficiencies about rice production for main grain producing districts from 1988 to 2008 (we get rid of the date of 2001 due to unavailability).The study shows that, in view of the overall situation, the technical efficiency of rice in main grain producing districts stay a certain upper level, and becomes balance at the district level. To large degree, There are natural disasters to impact producing technical efficiency in main grain producing area. Based on the whole analysis, this paper comes up to improve the conditions for agricultural production to reduce loss of natural disasters; expand the main food crop planting area; strengthen well-bred breeding and popularization, further improve the efficiency of conversion technology. so as to increase our nation’s grain producing technical efficiency.
