城镇化进程中的粮食安全问题:一个研究综述

A comprehensive literature review:Food security issues during the process of urbanization

研究城镇化进程中的粮食安全问题,本质上是城镇化进程中产业之间的协调问题。中国的城镇化由于规模庞大、人口众多,使得城镇化是否影响粮食安全的研究一直伴随着国家城镇化水平的提升而从未间断过,特别是中国开始进入城镇化快速发展阶段之后。在简单回顾城镇化与粮食安全问题研究历史的基础上,通过着重梳理近十年来中国城镇化对粮食安全的研究文献,从城镇化影响粮食安全的因素和城镇化背景下保障粮食安全的解决方案两个角度的内容出发,指出了研究侧重点的发展变化。在影响因素问题上,研究者们从最初的侧重关注耕地减少,到探索农业生产技术应用提升农业生产力,再到保障劳动力的资源水平和满足粮食消费,越来越全面地认识城镇化对粮食安全的影响。而在解决方案上,从战略政策的演变,到夯实生产能力的策略变化,再到对海外资源依靠方式的转变,体现出不断完善的粮食安全保障体系建立。最后认为未来的研究可以在空间异质性、人力资本和制度要素变化上进一步深入。

Studying the impact of urbanization on food security is a problem of coordination among industries in the process of urbanization.Because of large population,the research about urbanization affecting food security has been popular with the improvement of the national urbanization level,especially after China has entered the stage of rapid urbanization.Based on a brief history of urbanization and food security research,this review sorts out literature over the past decade and points out development and changes of research focus from the perspectives of the factors and the solutions.In the field of factors,researchers gradually focused on farmland reduction,technology adoption for increasing agricultural productivity,human capital and consumption,which gives more and more comprehensive understanding of the impact of urbanization on food security.In the field of solutions,researcher gradually established an improving food security system in the context of urbanization,which appeared in the evolution of strategic policies,the way to strengthen production capacity and the changes depending on oversea resources.Finally,this review thinks it worth doing further research in spatial heterogeneity,human capital and changes in institutions.
