The study investigates the relative importance of supply-side and demand-side factors of household food security through a logistic regression analysis applied to data collected from 247 sample households in Southern Ethiopia. Among the nine factors included in the model, seven were identified as statistically significant determinants of household food security: technological adoption, farming system, farm size, land quality, household size, per capita aggregate production and access to market. Among these, technological adoption, farming system, farm size, and land quality are supply-side factors. Household size, per capita aggregate production, and access to market are demand-side factors. Based on the magnitude of their partial effects on the probability of food security, supply-side factors are more powerful than the demand-side factors in determining household food security, implying that interventions focused on these factors need to get priority attention by policy, research and extension.

本研究通过对埃塞俄比亚南部247个样本家庭的数据进行logistic回归分析，探讨了家庭粮食安全的供给侧和需求侧因素的相对重要性。在该模型所包含的9个因素中，有7个被确定为家庭粮食安全的统计显著决定因素:技术采用、耕作制度、农场规模、土地质量、家庭规模、人均总产量和市场准入。其中，技术采用、耕作制度、农场规模和土地质量是供给侧因素。家庭规模、人均生产总量和市场准入是需求方面的因素。从它们对粮食安全概率的部分影响的大小来看，供给方面的因素比需求方面的因素在决定家庭粮食安全方面的作用更大，这意味着针对这些因素的干预需要得到政策、研究和推广方面的优先关注。
