There can no longer be any argument over whether Scotland can afford to be independent, the Finance Secretary has said.
John Swinney told delegates at the SNP conference in Glasgow that "the answer was yes and the case is closed".
"The question our opponents have to answer is: can we afford the consequences of remaining part of the UK?" he said.
Mr Swinney used his address at the SECC in Glasgow to set out how "Scotland will not only stand on her own two feet and survive" but also how "the economy can and will thrive".
The Finance Secretary said Scotland was already "holding our own" against "the backdrop of global economic problems and UK mismanagement".
He said the economic future of the country was "at the heart" of the debate on independence.
"We must persuade Scotland of the strength of our country's future and we need to do that now because for year after year our country has been told that we can't afford to be independent," he said.
Mr Swinney pointed to last week's Government Expenditure and Revenue in Scotland figures, which the Scottish Government said showed Scotland in a stronger financial position compared with the whole of the UK, taking North Sea revenues into account.
"Scotland contributed 9.6% of UK taxes but we received only 9.3% of UK spending in return," he said. "With only 8.4% of the UK population we paid more than our share and got less back.
"Two years ago in 2009-10 Scotland paid in 9.4% of UK taxes but again only 9.3% came back. Even when North Sea revenues fell by 50% Scotland paid in more money to the UK Treasury than came back. Last year we had a £2.6 billion advantage over the UK. An advantage worth £510 for every man, woman and child in Scotland."
