基于超效率DEA和Malmquist指数的湖南省农业全要素生产效率分析

Study on the Agricultural Total Factor Productive Efficiency of Hunan Province:Based on the SE-DEA and Malmquist Index Model

在湖南2007-2012年地市级面板数据的基础上,运用基于超效率DEA全要素生产效率测度模型,测算湖南省各地市(州)的农业全要素生产效率,然后利用Malmquist生产率指数法对农业生产效率进行动态对比研究。实证结果表明:2007-2012年间,湖南农业生产效率呈上升趋势,但各地市(州)之间差异较大,衡阳市农业全要素生产效率最高;Malmquist指数分析结果表明该期间农业全要素生产效率年均增长率为5.4%,通过Malmquist指数的进一步分解发现技术进步是推动湖南农业全要素生产效率增长的主要动力,但不同地区的增长动力具有差异性。

Using the municipal panel data in Hunan from 2007 to 2012, this paper employs SE-DEA to estimate every city’s ag-ricultural total factor productivity. Then the dynamic comparative study of agricultural total factor productivity has been done by using Malmquist index model. The results indicate that during this period, the agricultural total factor productivity in Hunan has an upward trend and Hengyang is on the leading position among all the cities, however, there is a big difference among cities. By using Malmquist index model analysis we know that the average annual growth rate of agricultural total factor productivity is 5. 4%. The further decom-position of growth rate shows that Hunan agricultural total factor productivity growth depends mainly on agricultural technical progress, while the growth momentums in different regions have differences.
