This study analyzes caloric intake in Iran as a proxy for food security to determine factors associated with caloric intake that could be impacted by policies. We modeled regional heterogeneity by analyzing a complete countrywide dataset disaggregated for rural intra-provincial areas using unique data from the Iranian Statistical Centre for 2007-2016. We applied logistic regression modeling and likelihood ratio tests to assess the association between socio-economic determinants and caloric intake among rural areas of all provinces. National policies (nation-wide food subsidies and a cash equivalent for food for each adult regardless of residence or income) had significant negative associations with caloric intake among all provinces. The detected spatial diversity suggests policies specific to each area could be more effective than a centralized national policy for food security. Rather than implementing one-size-fits-all policies, such as across-the-board cash food subsidies, the government should take a differential spatially targeted approach to directly support low-income households.
本研究以伊朗的热量摄入为代表来分析粮食安全，以确定与热量摄入相关的因素，这些因素可能会受到政策的影响。我们通过对 2007 年至 2016 年伊朗统计中心提供的独特数据进行省级农村地区的全国范围内数据集进行分析，研究了区域异质性。我们应用逻辑回归模型和似然比检验来评估社会经济决定因素与各省农村地区热量摄入之间的关系。国家政策（全国范围内的食品补贴和每个成年人的现金等价食品，无论其居住地或收入如何）与各省的热量摄入呈显著负相关。检测到的空间多样性表明，针对每个地区的具体政策可能比针对粮食安全的集中式国家政策更有效。政府不应该采取一刀切的现金食品补贴等政策，而应该采取差异化的、有针对性的空间方法来直接支持低收入家庭。
