A new report published by the corporation showed licence money spending had a positive knock-on effect for regional economies.
The total expenditure over the two-year period came to £4.3bn, which led to a gross value-added (GVA) boost to the economy of £8.3bn.
However, spending in London was three times the rest of the UK combined.
The report said: "The effect of initial BBC spending is 'multiplied' as it ripples through the economy from region to region and sector to sector (and to the employees of those sectors). This is known as the 'multiplier effect'."
The BBC's chief economic and policy adviser Najma Rajah explained: "The basic premise is that when the BBC spends a pound, the impact of that pound is 'multiplied' as that pound spent by the BBC creates value elsewhere in the economy.
"So, for example, if the BBC were to buy a camera from a supplier in Manchester, the camera supplier would receive some money in return for the camera.
"The camera company would then use the income generated from the sale of the camera to pay their suppliers for the components that went into the camera and to also pay their employees and so on."
Rajah added: "A really good example of how this multiplier effect works is when the BBC commissions a programme that is made by an independent television production.
"The programme might be filmed in Scotland using local runners, electricians, make-up artists etc. who are paid and then will spend their wages in Scotland to the benefit of the Scottish economy."
The report revealed significant growth in the north of England following the opening of the new BBC North headquarters in Salford Quays, with GVA growing 19.7% to £391m.
But in the Midlands, it fell 21.7% to £199m, while the south was down 18.8% to £699m and Wales dropped 6.2% to £276m.
London saw the biggest expenditure of £2.98bn - nearly three times as much as the rest of the UK combined - which in turn generated £5.65bn GVA.
John Tate, the BBC's director of policy and strategy, used the findings of the report to call on Ofcom to reverse its plans for a spectrum tax on broadcasters next year.
In a blog post he wrote:  "The wider benefit of the licence fee provides an extra reason for Ofcom to think again before it implements a spectrum tax next year: a levy on the spectrum broadcasters use to transmit their programmes.
"As well as hitting licence fee payers, such a tax would remove much-needed cash from the UK's creative sector."

The Mental Welfare Commission found elderly patients stuck on wards for months at the Royal Edinburgh Hospital because of a lack of care home places.
It also found patients left in bed until lunchtime due to staff shortages.
NHS Lothian said urgent changes were being implemented and the hospital would be redeveloped by 2016.
The commission, which expects NHS Lothian to act on its report, visited Royal Edinburgh's ward 14 and Canaan Ward, where dementia patients are assessed.
Dr Donald Lyons, the then chief executive of the commission, wrote to Tim Davidson, NHS Lothian chief executive, about its findings in March.
The letter said: "We found very poor evidence of activity provision, a serious concern about the high number of people who appeared to be delayed discharges and significantly poor care, apparently due to lack of staffing.
"I would particularly point out to you that, on Canaan Ward, we discovered that there were two individuals who were still in bed by lunchtime because staff had not had the time to get them up yet. This is not acceptable."

Batsman Godleman, 27, has signed a two-year contract, while Thakor, 22, has agreed a three-year deal.
Thakor has scored 606 runs at an average of 67, and taken 22 wickets at an average of 31, in nine County Championship matches this summer.
Godleman this week scored 100 against former club Essex - his third century in his last eight Championship innings.
He joined Derbyshire in 2012 after being released by Essex, while Thakor was signed from Leicestershire at the end of the 2014 season.
Head coach John Sadler said: "To secure Shiv's services for the next three years is brilliant for the club.
"He is a big player for us across all three formats and someone we can build our team around.
"He worked extremely hard over the winter and he's reaped the rewards this season.
"He has been brilliant and he is only going to get better and better."
The BBC generated more than £8bn for the UK economy in 2011-12, almost twice its licence fee spend.
