Answer: specialization
Step-by-step explanation:
Specialization simply refers to a production method whereby a country company produces the goods that it has a lower opportunity cost with regards to its production. This implies that more goods will be produced by the countries and at lower prices when compared to their counterparts.
With regards to the question, since Australia and China are trade partners and Australia sells natural
resources while China sells computers and cars, this is an example of specialization as the countries specialize in producing goods that they can produce more efficiently.
