“Wars without Gun Smoke”: Global Supply Chains, Power Transitions, and Economic Statecraft

Abstract

Abstract Conventional wisdom holds that conflict is highly likely during a power transition between declining and rising powers. The spread of global supply chains has provided new economic weapons for great powers waging these conflicts, but the businesses that constitute global supply chains can make it harder or easier for them to do so. A structural theory of business-state relations shows how power transitions affect a state's ability to exercise economic statecraft. As a dominant power and a rising power approach parity, they face structural incentives to use economic statecraft to decouple their economies. The resulting threat to businesses’ profits changes business-state relations: high-value businesses within the dominant power tend to oppose their state's use of economic statecraft, whereas low-value businesses within the rising power tend to cooperate with their state's use of economic statecraft. The Anglo-German power transition from 1890 to 1914 and the U.S.-China power transition since 1990 illustrate the theory. The findings shift scholarly debates on the use of economic statecraft in modern great power competition and have policy implications for weaponizing supply chains against rising powers like China.
