主要运用因子分析方法对畜产品消费需求量的影响因素问题进行了研究.首先确定了影响猪肉消费的14个影响因素,然后通过因子分析对影响因素进行降维处理,接着对因子进行了旋转,进一步修正了因子分析的结果,同时运用主成分分析,对因子个数的科学性进行了验证,最后确定了影响猪肉消费需求的3个主要因子,即需求因子、价格因子和人口因子.

 In this paper, issues on demand for animal products consumption mainly  are studied by using factor analysis. First, we determine 14 factors influencing pork consumption. Then we reduce the dimensions through factor analysis. Next,  followed by the rotation of the factors, the factor analysis results are
  further adjusted, while using principal component analysis,   scientific validation of the number of factors are conducted. Finally,    we determine 3 main factors influencing pork consumption, namely, demand factor, price factor and population factor.
