我们研究了津巴布韦统一社会现金转移支付（HSCT）在实施12个月后对家庭粮食安全的影响。我们通过一个众所周知的食品安全量表——家庭食品不安全获取量表（HFIAS）——以及由自己生产、市场购买和收到的礼物组成的家庭食品消费价值来衡量食品安全的决定因素。我们发现，家庭脆弱性的几个维度与粮食安全措施的相关性比与粮食消费的相关性更强。劳动力约束是HSCT对目标家庭使用的关键脆弱性指标，是粮食安全得分的重要预测指标，但不是粮食消费的重要预测指标，在淡季对粮食安全的影响更大。影响分析表明，该计划对食品安全和饮食多样性得分产生了统计上显著的影响，但对食品消费的影响为零或低。然而，总的粮食消费掩盖了家庭内部发生的动态活动，在这些活动中，现金被用来从市场上购买更多的食物，而对作为礼物收到的食物的依赖较少。这些现金反过来又使受益人在食物篮子中有更多的选择，从而改善了饮食的多样性。
We study the impact of the Zimbabwe Harmonized Social Cash Transfer (HSCT) on household food security after 12 months of implementation. We investigate determinants of food security as measured by a well-known food security scale - the Household Food Insecurity Access Scale (HFIAS) - and as measured by value of household food consumption composed of own-production, market purchases and gifts received. We find that several dimensions of household vulnerability correlate more strongly with the food security measure than with food consumption. Labor constraints, which is a key vulnerability criterion used by the HSCT to target households, is an important predictor of the food security score but not food consumption, and its effect on food security is even larger during the lean season. Impact analysis shows that the program has had statistically significant impacts on Food Security and Diet Diversity scores but null to low impacts on food consumption. However aggregate food consumption hides dynamic activity taking place within the household where the cash is used to obtain more food from the market and rely less on food received as gifts. The cash in turn gives beneficiaries greater choice in their food basket, which improves diet diversity.
