I'll come back to the description I was just using.
If a business can produce more with each hour of labour input it has, it will become more productive. If we do that en masse in the economy, the economy becomes more productive.
Often those improvements take a certain amount of investment, whether it's in training your employees or buying them different equipment. It also can be in our digital economy. It can be on intellectual property. Business investment that helps a business become more productive will help increase overall productivity.
