购销市场化下影响我国粮食综合生产能力的因素分析

Factor Analysis on the Influence of Grain Marketization on the Comprehensive Productivity of Grain in China

从系统学视角将粮食综合生产能力分解为4个因子。通过主成分分析和因子分析发现,水资源禀赋等自然生产力因子是影响粮食综合生产能力的基本因素;机械化率等科技生产力因子和耕作制度等人文生产力因子是主要因素;制度生产力因子影响不太显著,却是保障粮食综合生产能力的稳定因素。

The paper aimed to decompose grain comprehensive productivity into four factors from the perspective of the systenatics. Through the principal component analysis and factor analysis, the results showed that the nature productivity such as water resources was the basic factor in influencing the grain comprehensive productivity; the science ＆ technology productivity such as mechanization rate and the social productivity such as cultivation regime had the most significant effects on the grain comprehensive productivity ,and that the institutional productivity had no significant effects,but it was the stable factor in ensuring the grain comprehensive productivity.
