The MIA report, the fourth in a series on the impact of the recession on the conferences and events market, is sponsored by the Confex Group and was conducted during October and November last year.
Asked about the biggest challenge they faced going forward, 37% of respondents identified "increasing yield" while 15% cited "achieving value for money for clients".
Value for money was cited as the highest priority in venue selection by 69% of respondents.
The report also found that lead times continued to shorten, with 74% of those surveyed quoting lead times of between two and eight weeks.
MIA chief executive Jane Evans said: "The opportunities to win business are expected to grow in 2010 and the MIA is working to prepare members to ensure they are all well positioned to achieve maximum success."
