China’s Food Security Evaluation Based on Factor Analysis

Abstract

China’s food security has been a hot issue of social concern. Based on existing studies, this paper chose 12 factors to establish comprehensive evaluation system of good security, including the arable land area per capital, the fluctuation rate of grain yield, the grain price rising rate, the degree of agricultural mechanization, etc. Comprehensive evaluation of China’s food security over the years by factor analysis shows that China’s food security is in a tense balance state, the sources of which are the supportability factor slowdown and the score of stability factor decrease. Base on the analysis, we proposed to strengthen financial support to agriculture, improve the land protection mechanism, and improve the utilization rate of grain and other countermeasures to ensure China’s food security in the future.
