对2009—2011年我国30个省区粮食生产的投入产出效率进行了测度,结果表明:13个粮食主产区中仅吉林、黑龙江、山东、河南在3年中始终处在前沿面上,且处于投入产出前沿省份的数量呈下降趋势.进一步地,对粮食生产效率影响因素进行实证检验,结果表明:农户收入和政府对农业的财政补贴对粮食生产效率的影响并不显著,而城镇化推进与自然灾害,仍然成为粮食生产投入产出效率的制约因素.
The measurement of 30 provinces' Grain Productivity in China during 2009 to 2011 indicates that only Jilin,Heilongjiang,Shandong and Henan are on the production frontiers among 13 main grain production area and the amount of provinces that are on the production frontiers has declined. Furthermore,the result of the panel date regression shows that the effects of farmer income,government financial allowance,labor quality are not notable. However,the high speed of Urbanization level and natural calamities are the two factors that restrict the improvement of Grain Production.
