However John McLaren, of the University of Glasgow's Centre for Public Policy for Regions, declared business investment was still too low to suggest a fully-fledged recovery was underway.
David Tinsley of French bank BNP Paribas expects the recent economic momentum to continue over the next six to 12 months, with his outlook reflected by some economic consultants raising their growth forecast to as high as 3% in 2015. But he is surprised that view is not universally shared north of the Border.
Speaking in Glasgow after meeting clients in Scotland this week, Mr Tinsley said: "I have been looking at a lot of the indicators and it is quite clear that across a range of business surveys things have picked up really quite markedly.
"And there is no obvious reason why the momentum will fade.
"You can argue about where we might be in, say, the middle of next year. But over the next six to 12 months it seems like the momentum should be sustained and may even be strengthened.
"But I have been a bit struck coming up here how there are still quite a lot of sceptics. There are people still quite bearish on the UK and it is quite interesting.
"I think you can be a structural bear, in the sense that what we are seeing is a recovery that is probably a bit more than optimally led by the consumer [and] the housing market than you would like.
"Nonetheless it is going to be reflected in reasonably solid GDP growth."
Colin Borland, head of external affairs at the Federation of Small Businesses (FSB) in Scotland, said he is "not hugely surprised" to hear Mr Tinsley's optimism.
He said: "What we have seen is rising confidence almost quarter and quarter now.
"Now, it is all relative and we are maybe getting back to a level where we were say a couple of years ago. However the trend does seem upward."
But John McLaren questioned whether there was enough evidence to suggest a genuine recovery is underway.
He said: "The recovery, if you can call it that, is basically one quarter, which is Q2 of 2013, which will probably be revised at some future date as well.
"Up to that, there is not really much in the way of recovery. Business investment was falling all the way to Q1 of 2013, which is not a very good sign of a robust recovery.
"One of the things that has contributed most in the last five or six quarters has been consumers' household consumption, but that has been at the cost, certainly until the first quarter of 2013, of a falling savings ratio, which means it is not sustainable.
"It might be the start of something, but it is just one quarter in."
Mr Tinsley tempered his own analysis by highlighting that real income growth remains significantly behind inflation.
With recent data pegging those figures at 1.5% and 2.7%, he said real disposable income is shrinking per head, though said this is being offset to some extend by employment growth.
Mr Tinsley added: "It is a bit of an uneasy mixture which makes one wonder the extent to the momentum in consumer spending can build.
"It is not necessarily saying it will fall back, but the extent to which it can build further."
The economist also described the position on bank and corporate lending as soft. He insisted this will improve but said the question mark was over whether it improves "at a pace that sustains a decent pick-up in growth".
Mr Tinsley noted the correlation between the economy here and in Europe and said the better-than-expected GDP performance in the eurozone in quarter two as a factor fuelling the UK recovery.
But he said some factors unique to the UK alone are contributing to the improved outlook, citing renewed growth in the housing market that he said has been boosted by the Funding for Lending scheme.
Mr Tinsley played down fears the Government scheme, designed to stimulate lending by banks to households and businesses, was helping to fuel an unsustainable housing bubble.
He said the UK has faced a historic challenge going back 20 to 30 years to provide a sufficient supply of new stock to prevent big price rises occurring.
Mr Tinsley said: "At the end of the day the level of housing market transactions is still way below where it was pre-crisis. Any recovery or normalisation in the economy is going to involve an increase in housing market transactions - that is inevitable.
"And any increase in transactions is going to involve more mortgage lending. In the absence of a big increase in supply, it is going to put upward pressure on house prices."
He also said the effect of the new-build market on the economy can be overstated, stating that even when house building was growing rapidly in the early 2000s it contributed to just 0.4 percentage points of GDP.
On the debate over Scottish independence, he said the referendum was still seen by the City as too distant to have an effect on market behaviour at present.
However he highlighted a raft of economic complications that would emerge should Scotland vote yes on September 18 next year. These include how to calculate the share of UK debt and liabilities from bank bail-outs an independent Scotland should inherit to how the benefits from North Sea oil would be shared. Mr Tinsley said: "The Vienna Convention [on Diplomatic Relations] states there should be fair and equitable distribution of debt following a state leaving some sort of union. But that treaty has not been ratified by many states.
"When the USSR fell apart, Russia took on the liabilities of the USSR.
"But when Czechoslovakia split up, the Czech and the Slovak republic split the debt on a two-to-one basis which was roughly in line with their populations.
"There is not single obvious legal precedent for this. That is the sort of the thing the market would worry about if it came to pass."
He also said a currency union between an independent Scotland and the rest of the UK could shackle Scotland with "quite a lot of fiscal constraints".
