摘要

自2015年以来，粮食不安全的威胁比前几年更加严重，自2020年以来，特别是在发展中国家，粮食不安全的情况创历史新高。这一记录可能是由于采取了应对措施，特别是因COVID-19大流行而关闭边境。这意味着贸易开放在实现世界粮食安全方面发挥了重要作用。然而，关于贸易开放对粮食安全影响的争论在经济文献中仍未达成共识。正是在这种背景下，本文旨在重新审视贸易开放对撒哈拉以南非洲国家粮食安全的影响。方法动员2004年至2018年期间覆盖37个撒哈拉以南非洲国家的面板数据。我们使用基于系统广义矩法(GMM)的动态经验模型来控制解释变量的未观察到的异质性和潜在的内生性。由于粮食安全是一个多维度的概念，我们使用了四个指标(“平均膳食能量供应充足性”、“平均蛋白质供应”、“人均粮食供应变异性”和“膳食能量供应份额”)来捕捉粮食安全。为了提高开放对粮食安全实证效应的稳健性，我们还将全球化作为贸易开放的替代因素。结果实证结果表明，贸易开放显著改善了37个撒哈拉以南非洲国家的粮食安全。然而，在政治不稳定的情况下，粮食安全情况出现恶化。研究结果还表明，制度质量、经济增长、汇款、人力资本和农业部门的重要性也是影响撒哈拉以南非洲国家粮食安全水平的因素。任何旨在贸易开放的政策都必须考虑制度的质量，以实现预期的结果。

期刊介绍： Agriculture & Food Security is a peer-reviewed open access journal that addresses the challenge of global food security. It publishes articles within the field of food security research, with a particular focus on research that may inform more sustainable agriculture and food systems that better address local, regional, national and/or global food and nutritional insecurity. The journal considers cutting-edge contributions across the breadth of relevant academic disciplines, including agricultural, ecological, environmental, nutritional, and socio-economic sciences, public health and policy. The scope of the journal includes, but is not limited to: -Agricultural and environmental sciences, including genetics and systems ecology- Animal husbandry, fisheries science and plant science- Global change, biodiversity, climatology and abiotic stresses- Food technology and balancing agricultural outputs across food, feed, fibre and fuel- Economics, information sciences and decision theory- Strategies for the implementation of new policies and practices- Public health in relation to the condition of food and nutritional security. The pioneering advances in research reported in Agriculture & Food Security have far reaching implications both for the developing world and for sustainability in the developed world. The published articles are accessible not only to researchers, but are also of special interest to the wider community of farmers, development and public health workers, policy makers and the general public.
