RDA Northern Territory

Shift-share analysis

In the RDA Northern Territory, the strongest regional competitive effect between 2008/09 and 2022/23 was experienced in Metal Ore Mining.

Shift Share Analysis provides a useful mechanism for better interpreting changes in economic variables between different time periods. It is a way of breaking the growth or decline in an industry into three components to help understand what is driving the change. These three change components are commonly known as:

National/State growth effect - the amount of growth or decline in an industry that could be attributed to the overall growth of a larger area that encompasses the region's economy, usually state or national.

Industry mix effect - the amount of growth or decline in an industry that could be attributed to the performance of the specific industry at the national/state level.

Regional competitive effect - the amount of growth or decline in a specific industry that could be attributed to a local advantage or disadvantage. This is generally the most interesting component as it clearly quantifies the level of advantage or disadvantage an industry has in the local area.

The regional competitive effect for an industry generally indicates how the local industry performed against benchmark trends. An industry with a positive regional competitive effect suggests local characteristics supported above trend growth in that period. For example, if Retail Trade in a region grew by 3% but at a state/national level it only grew by 2%, some regional specific factors (e.g. new shopping centre, population growth) must have contributed to this above trend growth. A negative effect suggests the opposite.

An industry with a positive regional competitive effect may still have experienced decline, but by less than the state/national trends.
