论文摘要
使用不平衡的面板数据涵盖1991年至2019年的75个国家，我们探讨了政治风险如何影响食品储备的比率。经验发现表明，日益增加的政治风险会对食品储备的比率产生负面影响，并且对内部风险和外部风险均具有相同的影响。此外，我们发现外部或内部风险的增加既会对产量和出口产生负面影响，但是外部风险并没有对进口产生重大影响，并且对消费产生了积极影响，而内部风险对进口和消费产生了负面影响。结果表明，面对政治风险的增加，大多数政府都难以提高随后的食品储备比，无论其内部风险还是外部风险，尽管影响背后的机制是不同的。
Using an unbalanced panel data covering 75 countries from 1991 to 2019, we explore how the political risk impacts on food reserve ratio. The empirical findings show that an increasing political risk negatively affect food reserve ratio, and same effects hold for both internal risk and external risk. Moreover, we find that the increasing external or internal risks both negatively affect production and exports, but external risk does not significantly impact on imports and it positively impacts on consumption, while internal risk negatively impacts on imports and consumption. The results suggest that most of governments have difficulty to raise subsequent food reserve ratio in face of an increasing political risk, no matter it is an internal risk or an external risk although the mechanisms behind the impacts are different.
