Reliable supply chains are crucial to the productivity and economic growth of nations. Despite the recognition of its importance, especially brought to the forefront by the challenges of the coronavirus crises, formal research on the contribution of supply chain logistics is less forthcoming. This paper uses data on 130 nations to examine the relative effects of different aspects of supply chain logistics, including overall logistics performance, and the performance of the input and output dimensions of logistics, on economic growth. The results show that improvements in the supply chain logistics performance yield positive growth dividends. Further, the input and output dimensions of logistics performance have positive growth effects, with some quantitative differences. Significantly, the growth impact of logistics performance varies across nations with different growth rates. Implications for public policy and spillovers for COVID-19 initiatives are discussed.

可靠的供应链对于国家的生产力和经济增长至关重要。尽管认识到它的重要性，尤其是在冠状病毒危机的挑战中尤其突出，但有关供应链物流贡献的正式研究却很少。本文使用有关130个国家的数据来检验供应链物流各个方面的相对影响，包括整体物流绩效以及物流投入和产出规模对经济增长的影响。结果表明，供应链物流绩效的改善产生了正增长红利。此外，物流绩效的投入和产出维度具有积极的增长效应，但存在一些数量差异。显着地，物流绩效对增长的影响因国家而异，增长率也不同。讨论了对公共政策的影响以及对COVID-19计划的影响。
