Consider the following production chain. Gina Rinehart's mining company in Western Australia produces coal worth 20000 AUD in 2019 with no other purchased input. All of this output is bought by a Shanghai Steel, a Chinese rm, and using only coal as an intermediate good, it produces Steel worth 50000 AUD in 2020. All of the steel from Shanghai Steel is purchased by Holden Automobiles in Adelaide to make cars, using only imported steel as a purchased input.
