发展中国家粮食安全与贫困--基于“交换权利映射”的分析

The Theoretical Analysis of Relationship between Food Security and Poverty in Developing Countries

发展中国家贫困的特征表现为生产力和人均收入水平低,这两点导致了发展中国家个人的粮食获取能力受到制约。市场交易、自行生产和粮食援助是个体获取粮食的三种渠道。贫困通过对这些因素的影响最终导致了对粮食安全的威胁。"交换权利映射"通过个体拥有的资源与交换权利集合的映射关系说明了在发展中国家因为贫困而导致的个体拥有的资源匮乏而使其处在粮食不安全集合中。

In developing countries, poverty is represented by low productivity and low income per capita. These restrict the ability of the individual to access food in developing countries. Trade, own - production and food aid are three accesses to food. Poverty threatens food security by influencing these factors. Exchange entitlement mapping accounts for poverty leading to food insecurity by the exchange entitlement set.
