An Intra-State Regional Framework for Analysing the Western Australian Economy

Western Australia is a diverse state with unique regions. Studies on the economy that ignore regional developments are likely to be hindered by a lack of the richness and variability inherent in the intra-state regions. This note introduces a framework for analysing and projecting WA economic growth using a regional approach. As an export-oriented state, WA is affected by external factors such as the exchange rate, commodity prices and developments in emerging economies. However, with different composition of domestic- versus external-facing industrial sectors, each region is expected to respond differently to such shocks. Initial projections suggest WA’s growth is likely to decrease from its present 6.7 per cent to between 4-5 per cent through 2014-2015. When hit with an adverse shock to commodity prices initiated by, for example, a structural change in the Chinese economy, the mining-intensive region of Pilbara suffers by a factor of 4 percentage points in the near term over less exposed regions such as Great Southern and Peel.
