Nearly 80 per cent of respondents said the industry should voluntarily adopt a lower limit than that proposed by the Government.
More than 50 per cent said all agencies should publish differences in gender pay, no matter how many people they employ, while a further 21 per cent said agencies that employ more than 50 people should publish results.
More than 80 per cent of those surveyed either agree or strongly agree that publication of gender pay information will encourage employers to take positive action on the issue, indicating strong support for the industry to take the lead on this issue.
The PRCA has pledged to ask its members to adopt voluntary reporting of gender pay gap data, following a Government consultation which could see companies that employ more than 250 people forced to reveal this information.
Earlier this year, PRWeek reported how the average pay gap between men and women stands at between £8,500 and £10,000 for doing the same role.
Prime Minister David Cameron said in July that he wants to close the gender pay gap within a generation.
The PRCA said it will "name and praise" agencies which agree to publish gender pay data in the form of a quarterly report.
PRCA director-general Francis Ingham said: "The PRCA will publicly recognise all the firms that sign up, in the format of quarterly reports containing the names of all those that have confirmed their commitment to publishing gender pay gap data."
The CIPR has also thrown its weight behind initiatives to close the gender pay gap in PR and comms, with Sarah Pinch, its president, welcoming the industry fresh impetus to "pull its finger out and deliver action".
