The Future Watch 2011 report includes insight from more than 450 conference and events industry professionals in 20 different countries and from 67 MPI chapters.
A total of 11% of respondents were from EU countries, while 76% were from the US.
MPI president Bruce MacMillan said: "After two challenging years for the business of our industry, we’re back with Future Watch 2011 responses indicating material real growth in activity."
He added the research showed that virtual events and collaboration through social media would become increasingly mainstream.
"Thinking outside the room to drive performance through connectivity is becoming entrenched," said MacMillan.
