The data is published today ahead of the stage one budget debate at Holyrood this week – when the Scottish Conservatives will oppose the SNP’s damaging plans to tax families and firms more than elsewhere in the United Kingdom.
The analysis reveals that, had Scottish growth matched UK figures since 2007, our gross domestic product would have been £3.1 billion higher over the last ten years.
It equates to £1,291 per Scottish household.
The Scottish Conservatives will this week call on the SNP to ditch its plans to use new powers to turn Scotland into the highest taxed part of the UK - saying this will only cut growth even more in Scotland, leaving us all worse off.
Scottish Conservative shadow finance secretary Murdo Fraser said:
“This week’s budget should prioritise growth, by setting competitive taxes that help support jobs and the economy.
“Instead we have an SNP Government which is going to cut growth even further, by turning Scotland into the highest taxed part of the UK.
“The consequence of the SNP's low growth Scotland is laid bare in our figures. If we had matched UK growth over the last ten years, Scotland would have earned an extra £3bn – the equivalent of £1300 per household.
“The SNP now wants make this even worse. By increasing taxes, their plans will act as a ball and chain on growth, leaving us all poorer.
“Unless the SNP signal they are re-thinking their tax plans, we will be voting against this anti-jobs Budget this week.
"If the Budget falls as a result, that will be the Nationalists' own fault. Instead of using our new powers to set a course, they have been caught in the headlights.
"Time is now running out and they need to make up their mind. Are they for jobs and growth or against them?
"The Scottish Conservatives have a plan to grow Scotland: it is time the SNP listened.”
