An assessment of the effects on China's food security

摘要

This paper investigates the relationship between food industry and food security. With data obtained from China Statistical Yearbook and Chinese Rural Statistical Yearbook, we use panel data covering over a decade to construct an index system for estimating the food security of China and demonstrate the food security of China has decreased year by year. Our results imply that food industrial competition and industrial development circumstance contribute to dynamic changes commonly associated with the food security. Results suggest that an increase in the agricultural investment would have much larger economic impacts on national food security. Furthermore, under some conditions, science and technology input should be taken into account.
