The survey of 478 academies, by the membership organisation and think tank Reform, found that 64.9 per cent of academies have not altered terms and conditions and have no plans to do so.
Just 12 per cent had made changes, such as rewarding staff who take on additional work and those who lead on specific projects, and 13 per cent plan to make changes.
Four out of 10 said they had no need or desire to incentivise staff through altering their pay.
But six out of 10 added that national pay and conditions made it "culturally difficult" to change staff’s terms and one in five said they feared union opposition.
Plan A+: Unleashing the potential of academies calls for the removal of nationally agreed pay scales and terms and condition for teachers.
It states: "The continued existence of national pay and conditions makes it culturally difficult for academies to respond to local conditions, test innovative ways of working and incentivise recruitment of better teachers by improving rewards."
The survey also found that just under two-thirds of academies have changed their curriculum or plan to do so.
More than three-quarters said additional money was a motivating factor in converting to academy status, while educational autonomy was cited by a similar proportion.
The vast majority (95 per cent) said they had either maintained or improved relations with other schools since becoming an academy and 85 per cent said relations with their local council had improved or stayed the same.
School Network chief executive Sue Williamson said: "Critics of academy status declared that this movement would be the end of co-operative state education in this country. This survey shows that this is not the case. Schools are co-operating and working with local authorities more than ever before."
Christine Blower, general secretary of the National Union of Teachers, said she was unsurprised additional money was the chief motivator for schools to take academy status.
"The main reason given in the report for schools converting to an academy is the additional money they received," she said. "It is only through offering such bribes that the Education Secretary has had any success with the roll out of his unwanted academy programme."
Blower also rejected calls to abolish national pay and conditions in schools, adding that the move "will only lead to shortages of teachers in some parts of the country and is riven with likely inequities".
