The 2014 Ryder Cup at Gleneagles boosted the Scottish economy by £106 million and generated £22 million in Perth and Kinross alone.
An independent study shows the event in September last year attracted more than 63,000 visitors from outwith Scotland.
The biennial competition, which saw Europe’s golfers defeat the team from the USA, was hailed as the best-ever staging of a Ryder Cup by media, public and organisers alike.
The report compiled by Sheffield Hallam University’s Sport Industry Research Centre revealed that 57% of event spectators came from outwith Scotland, with 22% travelling from overseas to attend the event.
Attendees at the Ryder Cup accounted for a total of 133,104 bed nights during the week of the event alone, while a further 10,793 attendees extended their stay either pre or post event, which accounted for an additional 57,758 bed nights.
The report also revealed that almost three quarters of accommodation providers reported greater than normal takings compared with September 2013.
The experience of the event inspired spectators to return to Scotland, with 68% of attendees from outwith the country indicating they would visit again within a year for a leisure break.
The media value for the event totalled £42 million, including more than 5,000 hours of television coverage by 50 broadcasters in 200 territories.
Leader of the administration at Perth and Kinross Council, Councillor Ian Miller, said the report reinforced the long-term benefits that the Ryder Cup has had in Perth and Kinross.
He said: “The 2014 Ryder Cup and Junior Ryder Cup were magnificent for Perth and Kinross and we feel strongly that these events have left a powerful legacy here.
“Every day we see the improved infrastructure in use by the local community and visitors, such as the new, safer A9 link road by Gleneagles station and the 4G network now accessible in rural areas.”
Chairman of VisitScotland Mike Cantlay said: “The 2014 Ryder Cup showed what Scotland can do on the world stage and we were honoured to throw open our doors to so many spectators from countries around the globe.”
