根据2006--2011年中国15个玉米主产省区的玉米生产成本面板数据，采用随机前沿生产函数对玉米生产技术效率进行测算，结果表明：15个玉米主产省区玉米生产的平均技术效率约为78．5％；人工成本等要素投入对玉米生产技术效率存在反向影响，而玉米价格、灌溉等因素具有正向影响；各省区之间玉米生产技术效率差距较大，黑龙江、吉林、内蒙古等省区的玉米生产效率最高，辽宁、山东、河南等省次之，而四川、贵州、湖北等省最低，呈现出较强的南北差异性。因此，在玉米产业发展中，要逐渐由要素投入为主向技术效率提升为主转变，通过发展专业合作社等路径推进优势区域的规模化和专业化玉米种植，完善价格支持系统以强化价格对玉米生产的促进作用，并努力提高玉米灌溉效率。

According to panel data of corn production cost in 15 main corn planting provinces of China during 2006- 2011, by using stochastic frontier production function, corn production technical efficiency is calculated, and the results show that average technical efficiency of corn production in 15 main corn planting provinces is 78.5 percent, that the factor input such as labor and so on has reverse influence on technical efficiency of corn production, however, the factors such as corn price, irrigation and so on have positive influence, that there is big difference of corn production technical efficiency among all provinces, for example, corn production efficiency in Heilongjiang, Jilin, Inner Mongolia and so on is highest, the efficiency in Liaoning, Shandong, Henan and so on is second, the efficiency in Sichuan, Guizhou, Hubei and so on is lowest, which demonstrates the strong difference between the north and the south. Thus, in the development of corn industry, China should change from main factor input to main technical efficiency upgrading, push forward regional specialized corn planting on a large scale by the paths such as developing specialized cooperatives and so on, perfect price support system to consolidate the boosting effect on corn production by price, and make efforts to promote corn irrigation efficiency.
