以2011年咸阳市秦都区调查数据为基础,利用主成分分析方法对影响粮食产量的因素进行了分析.结果表明:人工费、种子费、化肥费和农药费对粮食产量影响较大.据此提出了提高农村劳动力素质、加大高产种子的培育力度、适当增加对农药和化肥的投入的建议.%According to the survey data of Qindu district in Xianyang city in the year 2011, the author used the principle component analysis to analyze the factors affecting the grain yield. The results showed that the labor cost, seed cost, chemical fertilizer cost and pesticide cost had great influence on the grain yield. Based on these results, the author put forward the following suggestions: enhancing the quality of rural labor force, strengthening the breeding of high - yielding seeds, and appropriately increasing the input of pesticide and chemical fertilizer.
