摘要

粮食净进口发展中国家占全球国家总数的 30%,约占全球人口的 20%,这些国家必须设法降低其在粮食生产贸易冲击中的脆弱性。本研究利用 2017 年国际比较方案八类食品的数据,调查了 60 个粮食净进口发展中国家的人均粮食消费模式。研究采用线性近似、近乎理想的需求系统模型,得出了边际份额、收入和价格的需求弹性,揭示了消费行为以及对收入和价格变化的反应能力。研究结果表明,人均食品消费的额外开支主要分配给水果、蔬菜、肉类、面包和谷物,但各国之间存在很大差异。同时,在糖和蜂蜜以及油脂方面的分配极少。收入弹性表明各类食品的反应程度各不相同。与此相反,自有价格弹性强调了对价格波动的高度敏感性,尤其是饮料、牛奶、奶酪和鸡蛋、肉类、油脂以及鱼类和海产品。此外,交叉价格弹性表明,平均而言,成对食品类别之间主要存在替代关系。此外,我们还绘制了一张直观的地图,显示八类食品的边际份额、收入弹性和自有价格弹性。这些发现为政策制定者和利益相关者了解消费动态、制定有效战略以解决粮食净进口发展中国家的粮食安全和福利问题提供了宝贵的见解。

Analyzing per capita food consumption patterns in net food-importing developing countries

Net food-importing developing countries, which account for 30% of countries globally, and roughly 20% of the global population, must seek to reduce their vulnerabilities in food production trade shocks. This study investigates per capita food consumption patterns in 60 net food-importing developing countries using ICP 2017 data for eight food categories. Employing the linear approximate, almost ideal demand system model, the research derives marginal shares, income and price elasticities of demand, shedding light on consumption behaviors and responsiveness to changes in income and prices. Results highlight that additional expenditure on per capita food consumption is primarily allocated to fruits, vegetables, meat, and bread and cereals, with considerable variations among countries. At the same time, minimal allocation is observed for sugar and honey, as well as fats and oils. Income elasticities indicate varying degrees of responsiveness across food categories. In contrast, own-price elasticities underscore significant sensitivity to price fluctuations, notably for beverages, milk, cheese, and eggs, meat, fats and oils, and fish and seafood. Moreover, cross-price elasticities suggest predominantly substitution relationships between pairs of food categories, on average. Additionally, a visually informative map displaying estimated marginal shares, income elasticities, and own-price elasticities for the eight food categories was created. These findings offer valuable insights for policymakers and stakeholders in understanding consumption dynamics and formulating effective strategies to address food security and welfare concerns in net food-importing developing countries.
