摘　　要：利用2001-2008年中国22个玉米主产区的投入与产出面板数据建立了随机前沿生产函数模型,并对中国玉米生产的技术效率进行了测算,全国玉米生产平均技术效率为0.862。在此基础上,进一步探讨分析了技术效率的时间差异、地区差异和收敛性,发现玉米生产技术效率随时间波动且地区差异明显,但从全国来看,各省份之间的玉米生产技术效率的差距正在逐步缩小,具有趋同的趋势。今后应提高玉米生产技术效率,加大政府投入力度,提高机械化水平,进行科学管理;加强玉米生产技术的研发和创新。A stochastic frontier production function model was established based on the 1995-2008 input and output panel data of China＇s 15 major maize producing areas,and then it was used to measure and analyze the technical efficiency of maize production in China.On this basis,a further exploration was made to analyze time difference,regional differences and convergence of technical efficiency.The results showed that the technical efficiency of maize production varied over time and had obvious regional differences,but from a national perspective,the efficiency gap of maize production among various provinces was narrowing,with the convergence trend.To improve the technical efficiency of maize production,measures should be taken to increase financial aid,enhance mechanization and scientific management,and strengthen RD of maize production techniques.
