The survey - by staffing, consulting and outsourcing firm, Aquent - revealed that a marketing director's post in Hong Kong paid between US$77,000 and $154,000 annually, compared with $69,000 and $92,000 in Singapore.
For design and creative directors, Singapore outranks Hong Kong with a salary range of $115,000 and $173,000 compared with $76,000 and $153,000 in Hong Kong.
Aquent Hong Kong area manager, Duncan Cunningham, said that while both Hong Kong and Singapore have been hard hit by the sluggish global economy and the atypical pneumonia outbreak, Hong Kong's drop was steeper because its salary levels were at unrealistically high levels several years ago.
He expects that salaries would continue to stagnate in the near term as employers look for freelance and ad hoc options rather than take on permanent staff.
"Our belief is that the situation will not worsen significantly because of the expectation that the market will become more competitive," Cunningham said.
Agency chiefs said the figures underlined the point that Hong Kong's role as a regional centre for the marketing communications industry remains under pressure.
Part of the problem is that despite more than three years of deflation, Hong Kong remains one of the costliest cities in the world to do business in.
Grey Global Group Southeast Asia president Chris Leong said: "Cost factors and the need to be closer to the markets you are serving means that senior executives are relocating to Shanghai to oversee China or moving to Singapore for Southeast Asia and even regionally."
She believed that the trend would continue especially on the client side because they still pay expat perks.
"Agencies have generally stopped paying perks except for the top two or three executives. But clients still have them so they will have to calculate the most cost-effective place to locate their people."
She stressed that if the regional marketers were moving to Singapore, then agencies would follow suit.
Leong and Cunningham added that many markets have taken steps to make themselves more attractive to foreign investors, including lowering income taxes.
