城市化加速期粮食安全要素的研究

随着中国城市化进入加速期,大量农村剩余劳动力转移到城市,大面积农用耕地转为非农用地,粮食供求矛盾发生了新的变化,粮食安全成为稳定社会经济的焦点问题。运用边际分析等方法从粮食安全要素角度对粮食安全主要架构,如:粮食生产安全、粮食供给安全、粮食消费安全等方面进行了研究,得出城市化加速期粮食安全是粮食生产、粮食供给价格、农民种粮意愿和城市居民粮食消费偏好的函数,并提出达到粮食安全的相应对策。

The Research for Grain Security Essential Factor in the Period of Urbanizing Acceleration

Entering the acceleration period along with our country urbanization, the massive countryside surplus labor force shifts to the city, and large area of agricultural cultivated land was transferred to be non-agriculture use. The contradictory of grain supply and demand had the new change, and the grain safety has become to be the focus to stabilize social economy. This article utilizes method of marginal analysis to study the main construction of grain safety from the grain security essential factor angle, like: the grain production safety, grain supplies security, grain expense security. The results show that the grain security in urbanizing acceleration period is the function for grain production, grain supplies price, the farmer''s will for planting crops, and consumption habit of urban people. And the paper proposed the corresponding countermeasure for achieving the grain security.
