The RBA famously described the China mining boom as a three phase event:
The mining boom can be viewed as a confluence of events that have boosted mineral commodity prices, mining investment and resources production. This combination of shocks has boosted the purchasing power and volume of Australian output. It has also led to large changes in relative prices, most noticeably an appreciation of the exchange rate. The combination of changes in income, production and relative prices has meant large changes in the composition of economic activity. While mining, construction and importing industries have boomed, agriculture, manufacturing and other trade-exposed services have declined relative to their expected paths in the absence of the boom. Households that own mining shares (including through superannuation) or real estate have done well, while renters and those who work in import-competing industries have done less well.
In short, high prices leads to high investment leads to high output. All three phases have virtually played out now.
