河南省粮食综合生产能力影响因素的量化分析结果及其政策含义

QUANTITATIVE ANALYSIS AND POLICY IMPLICATIONS OF THE INFLUENCE FACTORS OF GRAIN COMPREHENSIVE PRODUCTIVITY IN HENAN PROVINCE

通过分析明确影响粮食产量的主要因素,使用2011-2013年河南省各地区相关数据的均值,通过主成分分析法求出分析影响河南省粮食产量的主成分,达到降低影响因素数量的目的。通过线性回归找到分析粮食产量和主成分之间的量化关系,进一步求出各影响因素对粮食产量的边际影响,以分析现在河南粮食生产的投入状况和经济效益,并提出改进农业生产的政策建议。

This article analyzes the main factors influencing the comprehensive productivity of grain by means of principal component analysis（ PCA） to spot the principal components,using the data in various areas of Henan Province from 2011 to 2013 so as to achieve the purpose of reducing the number of influence factors. In this paper,the quantitative relationship between grain yield and principal components is found based on linear regression to find out the marginal impact of various influence factors on grain productivity so that analysis can be conducted of the current input status and economic benefits of grain production in Henan Province. Meanwhile,relevant policy is put forward.
