| Based on the analysis of wheat production resources in China,by using factor loading matrix theory,this paper builds the factor analysis models and ascertains the factors that influence the general output of wheat and their effect weight. It is discovered that the first factor impacting wheat output in all is resources factor,including science and technology development level,agricultural resources,etc.;the second factor is input and output factor,including price and revenue;the third factor is policy factor,including subjunctive policy variables and the price rate of industrial commodities to agricultural commodities;the fourth factor is climate factor,especially the disaster-suffered proportion.Therefore,to improve the integrated throughputs of wheat,it is necessary to follow the principia of "policy the first,science and technology the second and investment the third". |
