英文文献摘要：
A comprehensive analysis of food demand and nutrient consumption using recent, representative household survey data from Malawi is presented. Expenditure and price elasticities have been estimated for 20 food groups using a quadratic almost ideal demand system based on 4 income groups identified by the Goldfeld-Quandt tests. Although the current boom of maize price provides an opportunity to rethink development strategies that diversify the commodity sectors, developing countries will not necessarily benefit from this change absent significant improvements in production capacities and trade infrastructures. Malawi is likely to suffer from higher commodity prices in the short-run.
利用马拉维最近具有代表性的住户调查数据，对粮食需求和营养消费进行了全面分析。使用基于Goldfeld-Quandt检验确定的4个收入群体的二次型近乎理想的需求系统估计了20个食品群体的支出和价格弹性。虽然目前玉米价格的暴涨为重新考虑使商品部门多样化的发展战略提供了机会，但如果生产能力和贸易基础设施没有显著改善，发展中国家就不一定会从这种变化中受益。短期内，马拉维很可能会受到商品价格上涨的影响。
