中国粮食作物全要素生产率评价研究

摘要

运用DEA-Malmquist指数模型,构建"四投入、一产出"的评价指标体系,对2007~2015年中国13个粮食作物主产区全要素生产率进行评价,包括技术效率、技术进步效率.结果表明,由于技术效率(0.990)和技术进步效率(1.201)的双重作用,中国粮食全要素生产效率实现以年均1.1倍的速度增长.技术进步是促进全要素生产率增长的主要动力,技术效率的衰退是影响全要素生产率增长的重要阻力.%Making use of DEA-Malmquist model , this paperbuildevaluation index system with four input and one output .It made evaluation on total factor productivityof thirty main production with food crops in China from 2009 to 2015 including technical efficiency and technical progress efficiency .Results shown that due to the dual role of technical efficiency (0.990) and technological progress efficiency (1.201),Chinesetotal fac-tor productivity grown at an annual rate of 1.1 times.Technological progress was the main driving force for to-tal factor productivity growth .The decline of technical efficiency was an important resistance to total factor pro-ductivity growth .
