河南省农业生产要素贡献率的比较研究

选取我国粮食产量最大的河南省作为研究对象,以1978~2009年粮食产量作为产出指标,从业人数、耕地面积、农业机械动力、有效灌溉面积、化肥施用量、农村用电量作为投入要素指标,运用逐步回归进行演算,定量分析河南省农业投入要素与产出量之间的关系。结果表明,在耕地要素投入基本不变的情况下,化肥和电力的投入对农业发展贡献突出。最后有针对性地提出了建议和措施。

Comparative Study on the Contribution Rate of Agricultural Production Factors in Henan Province

With Henan Province which has the largest grain output in China as the research object,the grain yield from 1978 to 2009 as the output indicators,the number of employees,farmland area,power of agricultural machinery,effectively irrigated area,consumption of chemical fertilizer and rural electrical consumption as input indicators,the stepwise regression method was adopted to quantitatively analyze the relationship between the agricultural input and output in Henan Province.As indicated by the results,the inp...
