本文运用数据包络分析了中国玉米工业深加工消费行业的生产效率,发现玉米酒精系列产品加工业的纯技术和规模效率均达到较高水平,玉米淀粉系列产品加工业的纯技术效率较低且规模效率较低,因此需要淘汰落后产能、扩大企业规模来提高整个行业收益水平。 This paper uses data envelopment to analyze the production efficiency of China’s deep processing of corn industry, found that the pure technology and scale efficiency of corn alcohol series products processing industry reached a high level, the pure technical efficiency of corn starch series products processing industry is low and the scale Low efficiency, it is necessary to eliminate backward production capacity, expand the scale of enterprises to improve the level of the entire industry income.
