摘要
通过建立计量经济模型,运用Eviews3.1和Exce l2003软件处理数据,采用逐步回归法分析1990～2007年影响我国种植业经济增长的因素主要有：化肥施用量、耕种总面积、农业劳动力。化肥施用量对我国农业总产值的弹性系数为1.8;耕种总面积对我国种植业总产值的弹性系数为4.29。农业劳动力对我国种植业总产值的弹性系数为-1.7。
Through the establishment of an econometric model,the using of software of Excel2003 and Eviews3.1 to process data.Analyze of factors that impact on the economy growth of planting industry in 1990-2007 by using stepwise regression.The main factors that impact agriculture and economic growth are： the level of fertilizer input,the amount of farming total area,and the amount of agricultural labor.The elasticity of fertilizer input level to total agricultural output value was 1.8.The elasticity of the amount of farming total area to total planting indusrty output value was 4.29.The elasticity of the amount of agricultural labor to total planting indusrty output value was-1.7.
