Based on the increasing size of the service sector, some believe that growth in advanced countries has come without much change in the physical weight of output. To investigate the question, I generate rough estimates of the physical weight of Australian output from 1831 to 2018, using data on the weight of traded goods. These ballpark estimates imply that the weight of annual output increased from around 50,000 tonnes to around 800 million tonnes. Over the long term, a 10 per cent increase in real GDP was associated with a 12 per cent increase in the physical weight of output.

将澳大利亚经济规模化

基于服务业规模的增长，一些人认为，发达国家的增长在产出的实际重量方面没有太大变化。为了调查这个问题，我使用贸易商品重量数据对1831年至2018年澳大利亚产出的实际重量进行了粗略估计。这些估算表明，年产量的权重从大约50,000吨增加到大约8亿吨。从长远来看，实际国内生产总值增加10％，而产出的实际重量增加12％。
