摘要

在沙特阿拉伯,鸡蛋是一种直接或间接(作为其他食品的配料)广泛消费的主食。鉴于鸡蛋在沙特消费者饮食中的重要性,本研究旨在确定影响沙特消费者鸡蛋需求的社会人口因素,以及鸡蛋价格和消费者收入的变化如何影响鸡蛋的膳食摄入量。本研究分析了来自 466 名受访者的调查数据。我们使用双对数需求模型得出了鸡蛋需求的价格和收入弹性。结果显示,鸡蛋需求的价格弹性为负且无弹性,表明鸡蛋价格的变化对鸡蛋需求的影响较小。此外,收入弹性为正且小于 1,这意味着鸡蛋是一种必需食品。交叉价格弹性表明,奶酪和牛奶是鸡蛋消费的补充。同时,玉米片(一种早餐谷物)被认为是鸡蛋的良好替代品。此外,研究结果表明,随着家庭人口的增加,消费者对鸡蛋的需求也会增加。与男性相比,女性对鸡蛋的需求量更大。营养素收入弹性表明,消费者收入增加会增加鸡蛋中蛋白质、脂肪和卡路里的摄入量。营养素价格弹性表明,鸡蛋价格上涨对蛋白质摄入量的负面影响最大,导致鸡蛋消费量下降。本研究建议决策者积极监测鸡蛋价格,并采取一切必要行动防止鸡蛋价格飙升,因为这将改善营养和食品安全,并帮助消费者从鸡蛋消费中保持稳定的蛋白质摄入量。

Demand and Nutrient Elasticities of Egg Consumption: Evidence from Saudi Arabia
Chicken eggs are a staple food widely consumed directly or indirectly (as an ingredient in other food items) in Saudi Arabia. Due to the importance of eggs in Saudi consumers’ diet, this study aimed to determine the sociodemographic factors affecting Saudi consumer demand for eggs and how changes in egg prices and consumer income may influence dietary intake derived from eggs. This study analyzes survey data from 466 respondents. We used a double-log demand model to obtain the price and income elasticities of egg demand. The results show that the price elasticity of egg demand is negative and inelastic, indicating that changes in egg price have a small influence on egg demand. Additionally, income elasticity is positive and <1, implying that eggs are a necessary food item. Cross-price elasticities show that cheese and milk complement egg consumption. Meanwhile, cornflakes (a breakfast cereal) were found to be a good substitute for eggs. Furthermore, the results show that consumer demand for eggs is expected to increase as household size increases. Women exhibited a higher demand for eggs, compared with men. Nutrient income elasticity shows that an increase in consumer income increases protein, fat, and calorie intake from eggs. Nutrient price elasticity shows that an increase in egg price has the greatest negative influence on protein intake, resulting from a decrease in egg consumption. This study recommends that decision makers actively monitor egg prices and take all necessary actions to prevent spikes in egg prices, as this will improve nutritional and food security and help consumers maintain a stable protein intake from egg consumption.
