基于岭回归法的河南省农业产量影响因素研究

本文利用岭回归分析方法,基于河南省1995-2014年的面板数据,拟合了河南省农业生产产量与劳动力投入、土地投入和机械动力三要素之间的超越对数生产函数模型,探寻影响农业生产的因素,结果表明:目前劳动力投入是河南省农业增产变化的最大贡献因素,占所研究三要素总和的46.68%;机械动力产出弹性增加了8.09%,是增加最快的因素,机械动力能有效的替代人力劳动;农业生产函数处于规模报酬递减阶段。

This paper , by using ridger egres sanalysis based on panel date of henan province in 1995-2014 is a combination of henan agricultural production and labor inut,land in put and output mechanical power between the three elements beyonde the logaritnm production function model to explore the influencing factors of agricultural production.biggestcon tribution factor in the change of agricultural production in Henan province,Accounted for of the three elements of the study and the 46.68%;The mechanical power output elasticity increased by 8.09%, It wss the fastest growing factor , Mechanical power can effectively replace human labor ; Agricultural production function was in the stage of diminishing returns toscale.
