Sustained industrialisation is not possible without trade. While domestic demand provides the initial momentum for the circle to turn and to thus jumpstart the economies-of-scale and the rise in productivity, the sustainable growth of manufacturing industries requires access to foreign markets and technologies. This access helps boost demand and productivity spillovers considerably (UNIDO, 2017b). Specifically, developing countries can use spatial industrial policies to support the upscaling of their industrial capabilities, which may help them target global markets.
