中文摘要：

采用非参数的DEA方法对河南省2000-2011年粮食生产的平均综合技术效率、纯技术效率、规模效率和全要素生产率的构成和变化进行分析．结果表明，河南省粮食生产综合技术效率的增长主要与纯技术效率的提高有关，而规模效率的低下则是制约其提高的原因；全要素生产率的增长是由技术效率和技术进步共同带来的，但是全要素生产率的增长十分缓慢，有些年份甚至出现倒退现象；各市的粮食全要素生产率变化也不尽相同．河南省在粮食生产过程中应加强农业基础设施建设，加大科技投入和农业科技的推广力度．

英文摘要：

The non-parametric DEA method was used to analyze the composition of the average food production technical efficiency, pure technical efficiency, scale efficiency and total factor productivity and change of Henan Province from 2000 to 2011. The results show that Henan Province grain produc- tion technical efficiency growth is mainly related to the improvement of the pure technical efficiency and the low scale efficiency restricting the increase. The total factor productivity growth was attributed to the technical efficiency and technical progress, but the total factor productivity growth was very slow, some years appear even reverse phenomenon. The food total factor productivity change of each city is different. The construction of agricultural infrastructure in the grain production in Henan Prov- ince should be strengthened, and investment in science and technology should be increased, and the promotion of agricultural science and technology should also be strengthened.
