湖南省农业经济增长的动态面板分析

Dynamic Panel Analysis of Hunan Agricultural Economic Growth

摘要: 基于1988~2012年湖南省14个市州动态面板数据，运用广义矩估计GMM方法，对湖南省农业经济增长的影响因素进行实证研究。研究发现，前一期的农业经济、农作物播种面积、农业机械总动力和化肥施用量对农业经济增长有着显著的正向促进影响。有效灌溉面积和农业劳动力人数对农业经济增长具有负向影响。在此基础上，就促进湖南省农业经济增长提出了政策建议。

The result identifies that the former agricultural economic growth, the agricultural crop sown area, the total power of agricultural machinery and fertilizer input have a positive function of agricultural economic growth; while agricultural labor and effective irrigate area have a negative impact. On this basis, this paper puts forward policies to improve the growth of agricultural economy.
