尽管粮食自给自足被政策界视为保障粮食供应的有力策略，但政策措施的有效性，特别是其数量效应，仍不被充分认识。我们分析了 2001 年 1 月至 2018 年 12 月期间 10 个猪肉净进口国的国际和当地猪肉价格之间的关系。我们研究的主要结果是，猪肉商品的高自给率和小贸易量可能会削弱全球市场的价格波动传导。这一结果并不意味着应该建立保护主义制度来稳定国家粮食供应。考虑到经济主体预期效用的最大化，它提供了有用的信息，以平衡高效资源配置的效益和更高的粮食自给自足带来的市场稳定性。
Although food self-sufficiency is regarded as a potent strategy to secure food supply in the policy circle, the efficacy of policy measures, especially in terms of their quantitative effects, is still not fully understood. We analysed the relationships between international and local prices of pork between January 2001 and December 2018 for 10 net pork-importing countries. The primary outcome obtained in our research is that high self-sufficiency and a small trade volume of pig meat commodities could impair price volatility transmission from the global market. This result does not suggest that a protectionist regime should be established to stabilise the national food supply. It presents useful information to balance the benefit from highly efficient resource allocation and the market steadiness gained from higher self-sufficiency in food, considering the maximisation of the expected utility of economic agents.
